Up to 50 design decisions to consider in a high-performance roof

Up to 50 design decisions to consider in a high-performance roof

The design and construction of a roofing system is a complex undertaking that can involve up to 50 considerations. To ensure that state-of-the-art roofing practice is incorporated into the finished product, the licensed design professional, architect, engineer, building owner, facility manager or roofing contractor should have the latitude to select the most suitable product, system and assembly available on the market.

The factors that will impact roofing system design include:

Type of structure that needs to be protected.
Interior usage of the structure.
Geography and climate where the building is l

ocated.
Extreme weather conditions the roof will need to withstand (hail, high winds, etc.).
Orientation of the building.
Climatic impacts of the building.
Planned longevity of the roofing system and structure, as well as the recyclability of the roofing membrane.
Environmental impact of the materials to be used in the construction process.
Given these factors, the roofing professional can then determine the specifics of the roofing system design. This will include basic considerations such as how will the roofing membrane be attached to the roof deck. Options such as fully adhered, mechanically attached, and ballasted systems each offer unique benefits: a fully adhered system, for instance, which is attached to the substrate with adhesives, is essential to protect a roofing system in an area that frequently experiences high winds.

The roofing professional must also accommodate any special requirements presented by the overall design of the building (such as the presence of solar panels, plant equipment, generators, or other equipment adhered to the roofing surface). Will the roof be used for materials storage? How much insulation is needed, and how might that impact the choice of a roofing membrane? How will future access to the roof be managed safely to facilitate ease of maintenance? And finally, how will the construction of the roof be sequenced properly to ensure that a durable finished product is delivered on time, on budget and adhering to local building codes?

This complex orchestration of interdependent design and construction decisions requires a steady hand, a wealth of experience and access to a broad range of design solutions, not prescriptive requirements that limit creative choice.

Three tips for a great new roof

Three tips for a great new roof

Most houses in Canada have asphalt shingle roofs, and June is an excellent month to have new shingles installed. With hot weather on the way, shingles will seal down reliably later on in the summer sun. But June itself is also not usually so hot that the shingles will be soft and easily damaged underfoot during installation.

If you’re interested in getting the best possible asphalt shingle roofing job, there are details you need to discuss with your roofer. As with any other professional in life, don’t assume all roofers necessarily use the best possible techniques. Be your own watchdog by asking about the re-roofing details here and you’ll get the best possible results.

There are three parts to any great asphalt shingling job — the shingles themselves, the underlay system and the roof vents that round out any good installation.

Improved tar, gravel and substrates have boosted potential shingle lifespan enough that 40- and 50-year shingle warranties are now common. Thirty years ago shingles were sold with 10-, 15- and sometimes 20-year warranties at the top end. These days all manufacturers have doubled these numbers, and the difference is about more than just marketing.

The “10-year” shingles on the left lasted for 30 years before needing to be replaced. Thefibreglass shingles, right, have a rated lifespan of 40 years. (STEVE MAXWELL)

Most of the gain in shingle life comes from the use of fibreglass as a shingle substrate instead of the more traditional organic felt. Fibreglass shingles look the same as organic ones on your roof because they’re impregnated with the same kind of tar and gravel used as part of all asphalt shingles. That said, fibreglass is much more resistant to heat than felt, and this makes all the difference. Even on very hot, unventilated roof surfaces, fibreglass shingles consistently deliver their expected lifespan without curling. You also get a higher fire rating with fibreglass. In addition, fibreglass shingles are about 30 per cent thinner than organics for a given quality of shingle, making them easier to install on ridges, as part of woven valleys or any other application where bending of some shingles is required.

Ventilation is another critical roof issue. Most roofs need more of it than they have for two reasons — first, more ventilation reduces attic temperatures during summer, making it easier to keep upper floors cool, and second, attic ventilation allows internal moisture from domestic activities like washing, showering and breathing to vent away freely in winter, in case this moisture happens to enter the attic incidentally. You can’t have too much attic ventilation, and there’s no better time to install more vents than during a reroofing job. Ridge vents deliver the most ventilation for the least amount of visual distraction.

The best roof installations are waterproof before shingles go on, and this means more than just a layer of that old-fashioned, 15-pound tarpaper nailed to roof sheathing. There are two philosophies behind creating a reliable secondary layer of protection underneath your shingles, and they’re completely different.

The black fabric being installed here keeps water out if the shingles fail, but also allows watervapour to escape if necessary. (STEVE MAXWELL)

When self-sticking ice and water shield arrived on the scene about 25 years ago, it didn’t take long for it to replace tarpaper as a complete roof underlay on high-end installations. And this approach still makes a lot of sense, except for one universal Canadian issue.

Cold climates create a moisture threat that can attack roof structures from both top and bottom. In addition to the usual hazard of water leaking from above, there’s also the possibility of moisture condensing in parts of the roof structure from below during winter. This is why the best roof underlay these days is breathable. It combines the ability to shed water along with the ability to dry out from the inside.

Ask any prospective roofers for homeowner references, check them out, then go with a contractor who has a track record of good work and is willing to use today’s best shingling methods.

How to choose a quality roofing contractor

How to choose a quality roofing contractor

nstalling a new roof is one of the most important — and expensive — home improvement projects you’ll run into as a homeowner. Considering this, and the fact that your roof is your first line of defense against the elements, it’s important you hire a qualified, licensed professional for your roofing repair and installation

projects. There are a number of roofing companies to choose from, so it helps to follow a few basic rules to ensure that you find, choose and hire the best professional for the job.

 

TALK TO SEVERAL CONTRACTORS

Talking to several roofing companies will help you identify an honest and reasonable price range. You probably don’t want to hinge your final hiring decision on the difference of a few hundred dollars for a project that costs several thousand dollars, but you should be wary of any remarkably low or excessively high bids. Of course, this will also provide you the opportunity to gauge your level of rapport with each contractor as you work your way through the rest of the rules for hiring a qualified roofing professional.

 

RESEARCH CREDENTIALS

It’s also important to perform research on the different companies you’re speaking with — particularly those who stand out after your initial conversations. Reputable contractors should be licensed and willing to provide you with at least three references verifying the quality of their work. Confirming that a contractor is licensed — and speaking with past customers who can verify their credibility and qualifications — will give you added peace of mind.

REVIEW THE CONTRACT AND WARRANTIES CLOSELY

Never sign a contract without reading it over carefully. Professional contractors won’t be annoyed with your taking the time to understand the terms of your agreement — and most will be happy to sit down with you and explain parts you don’t understand. Also, make sure you understand the warranty that comes with your new roof. All materials and workmanship should be guaranteed for at least five years, and the roofing itself ought to come with a 20- to 40-year warranty.

COVER YOUR BASES

Before work begins, be sure to cover your bases. Check with your contractor about whether you need to acquire a permit (most roofing companies will take care of this as part of their service), and confirm that their employees are covered by workers comp as well. Finally, if you’re submitting an insurance claim on your roof, make certain you’ve followed all the necessary procedures — and undergone all the necessary approvals — before work on your new roof begins.

NEVER PAY THE ENTIRE BALANCE UPFRONT

Never pay the entire balance of your new roof up front. This goes for all large projects. If your contractor asks this of you, terminate your relationship and be sure not to sign a contract. Asking for a reasonable deposit and a payment schedule that parallels the work is common practice. In no case should you ever pay with cash. Using a credit card increases the likelihood that, in a worst-case scenario, you’ll be able to recover your money without expensive litigation.

Roof Maintenance

A residential property could have triple-reinforced titanium steel walls, and it still wouldn’t be worth a darn without a sturdy roof. It’s through the roof and rooftop features that many problematic elements can enter a building

, from wind to rain to ice to debris. And because of that, the roof must be adequately fortified and properly maintained. Otherwise, the integrity of the building – along with resident safety and property value – are bound to suffer.

Basics for Beginners

Roofs are not just complicated, relatively delicate structures—they’re also harder to keep tabs on than a facade, or windows that people look at all day. Fortunately, there are myriad experts – from property managers to A/E/C professionals to trades persons who work solely on roofs – who can do the job for your building and keep your roof in good repair.

“A roof should be inspected every few years,” says Frank Sausa, Vice President of Altura Construction Company, Inc., in Garfield, New Jersey. “If a leak gets severe enough, a homeowner’s ceiling can literally collapse. The most common cause of leaks that we see is when the rubber boot around plumbing vents deteriorates. Additionally, we often conduct repairs around chimneys, skylights and valleys, utilizing shingles, leak barrier ice and water shield, synthetic paper, step flashing, counter flashing, and, most importantly, kick-out flashings.”

Between formal inspections by a roofing professional, associations should be doing routine maintenance on their own. “Inspection of roofs should be part of the basic building maintenance, and reviewed at a minimum of a few times per month, especially during and after heavy rains or snow,” says Dennis DePaola, Executive Vice President of Orsid Realty Corp., in New York City. “Not only should the roofing surface, pitch pockets, and flashings be checked, but the floor below should be looked at as well, in order to catch even the smallest amount of water infiltration as early as possible, before any major damage occurs.”

Of course, roofs are not ‘one size fits all,’ and a maintenance schedule therefore depends on the make and age of one’s model, as well as the weather to which it’s subjected. “Appropriate frequency of inspections of a roof may depend on its age, but annually is probably a general minimum,” recommends Christopher R. Berg, President of Independent Association Managers, Inc., in Naperville, Illinois. “Severe weather conditions may necessitate specific inspections, particularly for shingled roofs. If you can see the roof from the ground, loose or missing shingles can be spotted by the board or management on a simple walk. However, many problems would only be identified via closer inspection. For example, an examination of the attic may identify leaks and problems that wouldn’t be apparent elsewhere, such as insufficiently ventilated bathroom moisture or dryer lint.”

In areas like New England, where the weather in a given year can reach sweltering highs and frigid lows, roofs can wear much faster than in more temperate regions. To be proactive, an association should perform a visual inspection of its roof on an annual basis,” suggests Tim Arel, Owner and Principal at North Point Management, which has offices in both Massachusetts and New Hampshire. “This inspection should look for missing or damaged shingles, as well as wear and warping. That will allow an association to perform the small and relatively easy repairs before they develop into serious issues that result in the need for full roof replacement, or damage to the buildings. Proactive annual inspections work to extend the life span of the roof, but they also provide information needed to plan for a roof’s eventual replacement. And they can initially be performed by qualified members of the management team, or by association volunteers. The key is to have individuals who know what they’re looking for perform these inspections. Then, when issues are identified, management and the board should contact a qualified roofing contractor to perform the needed repairs, or to provide a professional assessment with recommendations.”

Damage Done

Certain roof-based dilemmas are more common than others, so it pays for a board or management to be aware of the likely suspects.

“We’ve taken over buildings from other firms wherein we have found severe structural steel damage due to neglect, and the failure to stop water infiltration for prolonged periods of time,” notes DePaola. “In such instances, we’ve had to install shoring within apartments to offset the load from the damaged steel. That may require a relocation of the residents, depending on the severity of the situation.

“We’ve also been successful in spotting smaller repairs of roofing systems that are still under warranty, at little-to-no expense to the building owner,” he continues. “By regularly checking for these smaller repairs and addressing them in a timely manner, owners can greatly extend the useful life of the roofing system, sometimes well beyond their 20-to-25-year warranty.”

As one may intuit, ice is a major enemy in regions with particularly cold winters. “The improper removal of ice dams has been a significant contributor to roof damage over the past several years,” says Arel. “When faced with an emergency situation caused by interior water intrusion from ice dams, some vendors believe that the solution lies in removing the ice via the use of hammers and pickaxes. While this may temporarily alleviate the problem, the net result is often significant damage to shingles and roofs. This makes for a great example as to how proper planning and hiring vendors with the correct equipment will benefit an association in the long-term.”

And the type of roof – shingled or flat – also affects its aging process.

“Shingled roofs often age prematurely, as a result of insufficient ventilation and/or insulation, and may need to be inspected more frequently,” warns Berg. “When attics can’t vent the summer heat, cooked shingles will curl and break the adhesive that holds them down, leaving an edge up to become a sail in the wind. Sometimes you can be alerted by shingles on the ground or in the gutters, but other times they seem to have vanished from the earth. When attics can’t stay cold under snow-covered roofs, they cause ice dams that can lift shingles, split wood and bend metal, whether or not it causes visible interior damage. Rubber parts and applied sealants need to be inspected for cracking, so they can be replaced before they leak. However, gutters often have to be cleaned of leaves and other tree debris in both spring and fall, which makes for two great opportunities to just inspect all of the roofing.

“And then flat roofs have both masonry and metallic elements, in addition to drains, pipes, and other membrane penetrations, so they may need regular engineering inspections as well,” Berg adds. “Minor cracking in masonry joints and membrane transitions can lead to serious problems, whose resolution come with serious price tags. So the more complicated your roofing system is, the more regular inspections you may need, and by more technical professionals.”

Balance in Budget

The more on top (pun intended) of roof-related affairs an association is, the less likely they’ll have to spend exorbitant amounts of money to fix a disaster. With that said, unpredictable calamities, however, can happen, and an association is best served tucking away some extra funds in the event of a rainy day.

“Every association should have both short- and long-term capital plans for the essential building components,” says DePaola. “We know that roofing systems have a useful life between 10 and 30 years, depending on the system and the warranties received. Therefore, the association should be funding or implementing a plan to fund – via either borrowing or assessment – for the roof replacement during the entire life cycle of the capital component. The most costly roofing projects to which we’ve been privy are those that have not been planned for and those that have been deferred for too long.”

“Having a reserve study and financial plan in place to ensure that the funds needed for capital projects exist in the association’s reserve account is the best method to avoid the significant impact of special assessments,” Arel agrees. “Proper funding is always based on proactive planning. Unfortunately, a great number of associations are under-funded, and thus do not have sufficient reserve funds required for a significant capital project. In these occasions, associations need to evaluate their options to determine what plan best suits its owners. Due to the current financial environment, a great number of associations are looking to loans to make up for their lack of reserves. This option allows an association to borrow the necessary funding, typically through a fixed interest rate loan that may cost less per month than delaying work and facing the increased costs of labor and materials. When roofs need to be replaced within a several-year period due to leaks or other severe issues, financing the project allows an association to spread out the payment over a greater span, thus resulting in a lower monthly increase.

“However,” he continues, “it’s important to note that one option is not right for all association. A board should weigh all options and the financial impacts thereof and present that to the owners. It’s important to involve the owners when making any decision that will result in a significant fee increase, such that the owners can understand the process that the board has undergone and the options available, then provide input as to what they believe is the best option to meet the association’s needs.”

Roof Maintenance

Repairing or replacing your roof can be expensive. Spending a few minutes every six months looking closely at your roof can help you identify roof maintenance opportunities that will help prevent costly repairs later. It’s also important to periodically check your homeowners insurance to make sure that serious roof damage is covered by your policy.

Roof maintenance: What to look for

It’s critical that you inspect your roof every spring and fall. A good time to do this is when you’re cleaning your gutters.

Look for missing, damaged or curling shingles and any other signs of wear and tear. It’s easy and inexpensive to replace one or two shingles, or to hire someone to do it for you.
Check for signs of fungus or algae. If your roof is starting to collect moss or algae, install zinc or lead control strips.
Inspect metal areas for rust. If it’s present, wire brush the rust, then prime and paint the metal.
Examine the flashing to make sure it’s solid. If not, remove all of the old caulk and scrub the area clean before resealing.
Seal any cracked mortar or caulking around joints and chimneys, if it appears to be deteriorating.
If you see any signs of leaking, like dark spots on the ceiling, or mold or dampness in your attic, take action immediately. Roof leaks get worse, not better, and it’s better to spend a few dollars on roof maintenance rather than a lot on a big repair.

Other roof maintenance issues

Sweep or blow off excess debris on the roof. Sticks, leaves and other debris can damage shingles, cause algae to grow and eventually clog the gutters.
Trim any branches that are hanging over the roof to prevent damage and keep squirrels and raccoons away.
A thick layer of snow accumulation could lead to roof collapse. If this happens, carefully pull the snow off the roof using a snow rake available at most home improvement stores.
Roof maintenance is often ignored, but small problems with a roof can lead to some of the most costly home repairs around.

Roof Shingling Tips and Tricks

Roof Shingling Tips and Tricks

Roof shingling is an easy job to do yourself, especially if you use a few shortcuts that don’t compromise the quality of your work. Keep in mind that safety should always be your first priority when it comes to doing any construction work on a roof. With the proper equipment and know-how, you will be able to complete your shingling jobs without wasting money or time.

Shingle Over Shingles

 

Some professionals will suggest that you not place new shingles over the top of existing shingles. The reason is that asphalt shingles have a lifespan of up to 20 years. Placing multiple layers of shingles will give your roof time to develop problems that can’t be easily detected if the roof is stacked with shingles. It is acceptable, however, to add new shingles over existing shingles. The rule is that there should not be more than 3 layers of shingles already placed. While this is a time saving shortcut, it is best practice to strip the roof to inspect for any damaged areas of the roof.

The Best Roof Stripping Tool

On occasion you will see do it yourself roofers armed with a crowbar to strip the shingles from their roof. The best and most convenient tool for this job is called a Roofer’s Spade. This tool is very similar to a snow shovel but is out-fitted with teeth or notches in the front of the shovel and a fulcrum underneath. This allows the prying up of the shingles and nails to be much easier than using a crowbar or a regular shovel

 

Rent a Dumpster

When stripping your roof, there will be lots of debris that will come from atop, including nails. Instead of throwing the loosened shingles and nails into the back of your truck and causing damage, you can call your local equipment rental company and rent a dumpster. This will allow you to throw the debris directly into the dumpster and call the company to pick it up when 

 

you are done.

Underlay

The purpose of underlay is to be that second layer of waterproof and leakage protection on your roof. While many professionals and do it yourself experts will disagree, an underlay is not necessary to install before you add your shingles on your roof. If your shingles are properly installed, you will not have to be concerned with any roof leakage issues. Although adding an underlay of felt has become the industry standard for asphalt shingles, it is not crucially needed.

Ice Guard

When you have completely stripped your roof of all shingles, walk the roof again to check for any nails that didn’t come up during your initial sweep. Remove them if there are any and prepare your roof for an application of roof guard. Ice guard is waterproof membrane that will help protect your roof from water damage. Ensure you follow the directions of use and application.

 

 

Bar Magnet

Trying to find all the nails that fell from your roof to the ground is an all day job that you don’t have time for. To remedy this issue, tie a rope to a bar magnet and drag it along the perimeter of your house. You will pick up all the nails that your eyes could not see.

5 tips to think about when renovating roof

5 tips to think about when renovating, repairing and replacing your roof

1. Roofs should ideally be inspected twice a year or more, both from the outside (with binoculars) and inside the loft. If you can see daylight in the loft, there may be something missing on the outside. Roof tiles or slates that have broken, slipped or been blown off are a common occurrence. If they’re not replaced, rainwater will get into the loft and cause damage there, and then in the rooms below. Other parts of the roof can cause leaks and damp, too, including the flashing, guttering and chimneys. You may be able to spot these problems yourself, but will usually need a roofer to put them right.

2.If the roof has to be retiled, do you replace the tiles like for like or go for something different, provided there are no planning restrictions? “Although handmade tiles look great, they can make the job more time consuming – you may need an experienced roofing team to manage the materials,” says Simon Braithwaite, category manager at builders merchant Travis Perkins. “Handmade tiles are also expensive. Expect to pay around £1,000 per 1,000 tiles – the average detached house requires 8,000 tiles. Another consideration is the area – if you live in a rustic village, handmade tiles may be much more in keeping with your surroundings.”


3“Handcrafted tiles, which are tiles that have been dealt with by hand during part of the production process, usually cost much less than handmade ones,” says Braithwaite. “If you have a smaller budget, machine-made clay or concrete tiles are the most affordable options. Concrete tiles can degrade in appearance and structure over time, whereas clay lasts much longer and is more aesthetically pleasing.” He continues: “Another consideration is the roof pitch – you can’t use certain types of tile on certain roof pitches because they don’t look good and could cause structural problems.”


4 If you’re overhauling a roof, think about fitting skylights (again as long as there are no planning restrictions). Skylights (also called roof windows) come in all shapes and sizes and can make a big difference to the amount of light entering the room below. If you’re doing major building work, such as an extension or loft conversion, skylights are a great addition, but they can also transform existing rooms with little or no natural light. While fitting a skylight is usually a job for a roofer or builder, experienced DIYers can fit them. You may think that skylights are expensive, but they don’t have to be – the Tyrem range at Screwfix starts at £161.22 for a 550mm x 780mm double-glazed skylight. These skylights are straightforward to fit, have a handle instead of a bar, which can make opening and closing them easier, and come with a 10-year manufacturer’s guarantee – just remember to get the correct flashing kit for the type of roof covering.


5 Flat roofs can be prone to leaks, not least because they should have a gradient, but the gradient often isn’t steep enough. If the roof is too flat or doesn’t have an adequate structure or materials under the roof covering, it will sag, allowing rainwater to pool and eventually enter the room below. The roof covering can also get damaged. If you’re building a single-storey extension, putting a flat roof on it will enable you to easily access the house above (to repair the guttering on the main roof, for example), but a pitched roof should be more reliable long term and is more aesthetically pleasing inside and out.

12 Roof Repair Tips: Find and Fix a Leaking Roof

12 Roof Repair Tips: Find and Fix a Leaking Roof

You can stop leaks yourself-no experience necessary. We show you how to track down and fix the most common types of roof leaks. Most leaks take only minutes to repair.

Roof Leak Overview

Roof Leak Overview

If you have water stains that extend across ceilings or run down walls, the cause is probably a roof leak. Tracking down the leak is the hard part; the fixes are usually pretty easy. We'll show you some simple tricks for finding and repairing most of the common types of roof leaks. But if you live in the Snow Belt and in the winter you have leaks only on warm or sunny days, you probably have ice dams. We won't go into those fixes in this story. Check out this article for more on preventing ice dams.

If you have a roof leak, you'd better fix it immediately, even if it doesn't bother you much or you're getting a new roof next year. Even over a short time, small leaks can lead to big problems, such as mold, rotted framing and sheathing, destroyed insulation and damaged ceilings. The flashing leak that caused an expensive repair bill was obvious from the ceiling stains for over two years. If the homeowner had dealt with it right away, the damage and subsequent repairs would have been minimal.

How to Find Roof Leaks

How to Find Roof Leaks

When you're trying to track down a leak, start by looking at the roof uphill from the stains. (Plus: here's how to clean roof stains.) The first thing to look for is any roof penetrations. Items that penetrate the roof are by far the most common source of leaks. In fact, it's rare for leaks to develop in open areas of uninterrupted shingles, even on older roofs. Penetrations can include plumbing and roof vents, chimneys, dormers or anything else that projects through the roof. They can be several feet above the leak or to the right or left of it.

If you have attic access, the easiest way to track down a leak is to go up there with a flashlight and look for the evidence. There will be water stains, black marks or mold. But if access is a problem or you have a vaulted ceiling, you'll have to go up onto the roof and examine the suspect(s).

A Trick for Finding Difficult Leaks

A Trick for Finding Difficult Leaks

If a leak is difficult to find, enlist a helper and go up on the roof with a garden hose. Start low, soaking the area just above where the leak appears in the house. Isolate areas when you run the hose. For example, soak the downhill side of a chimney first, then each side, then the top on both sides. Have your helper stay inside the house waiting for the drip to appear. Let the hose run for several minutes in one area before moving it up the roof a little farther. Tell your helper to yell when a drip becomes visible. You'll be in the neighborhood of the leak. This process can take well over an hour, so be patient and don't move the hose too soon. Buy your helper dinner. If running water doesn't reveal the exact location of the leak, don't be timid. Start removing shingles in the suspect area. With them removed, there'll be evidence of the leak and you'll be able to track it down right to the source. You'll see discolored felt paper or water-stained or even rotted wood directly below and around it.

Solution for a Small Leak

Solution for a Small Leak

Some roof leaks are tough to locate. Sometimes the water shows up at a ceiling spot distant from the leak. If your ceiling has a plastic vapor barrier between the drywall and the attic insulation, push the insulation aside and look for flow stains on the plastic. Often water runs to openings in the vapor barrier, such as at ceiling light fixtures.

If you can't see any telltale flow marks, and since the stain is fairly small, look at the underside of the roof for 'shiners.' A shiner is a nail that missed the framing member, in this case when the carpenter nailed the roof sheathing to the rafters. Moisture that escapes into the cold attic from the rooms below often condenses on cold nails. Sometimes you can spot this if you climb up into your attic on a cold night. The nails will look white because they're frosted. When the attic heats up a bit during the day, the frost melts and drips, then the nails frost up at night again and so on. The solution is to simply clip the nail with a side-cutting pliers.

Fix Plumbing Vent Boots

Fix Plumbing Vent Boots

Plumbing vent boots can be all plastic, plastic and metal, or even two-piece metal units. Check plastic bases for cracks and metal bases for broken seams. Then examine the rubber boot surrounding the pipe. That can be rotted away or torn, allowing water to work its way into the house along the pipe. With any of these problems, you should buy a new vent boot to replace the old one. But if the nails at the base are missing or pulled free and the boot is in good shape, replace them with the rubber-washered screws used for metal roofing systems. You'll find them at any home center with the rest of the screws. You'll have to work neighboring shingles free on both sides. If you don't have extra shingles, be careful when you remove shingles so they can be reused. Use a flat bar to separate the sealant between the layers. Then you'll be able to drive the flat bar under the nail heads to pop out the nails.

Fix Roof Vents

Fix Roof Vents

Check for cracked housings on plastic roof vents and broken seams on metal ones. You might be tempted to throw caulk at the problem, but that solution won't last long. There's really no fix other than replacing the damaged vents. Also look for pulled or missing nails at the base's bottom edge. Replace them with rubber-washered screws. In most cases, you can remove nails under the shingles on both sides of the vent to pull it free. There will be nails across the top of the vent too. Usually you can also work those loose without removing shingles. Screw the bottom in place with rubber-washered screws. Squeeze out a bead of caulk beneath the shingles on both sides of the vent to hold the shingles down and to add a water barrier. That's much easier than renailing the shingles.

Fix Walls and Dormers

Fix Walls and Dormers

Water doesn't always come in at the shingled surface. Often, wind-driven rain comes in from above the roof, especially around windows, between corner boards and siding, and through cracks and knotholes in siding. Dormer walls provide lots of spots where water can dribble down and enter the roof. Caulk can be old, cracked or even missing between the corner boards and between window edges and siding. Water penetrates these cracks and works its way behind the flashing and into the house. Even caulk that looks intact may not be sealing against the adjoining surfaces. Dig around with a putty knife to see if the area is sealed. Dig out any suspect caulk and replace it with a siliconized latex caulk. Also check the siding above the step flashing. Replace any cracked, rotted or missing siding, making sure the new piece overlaps the step flashing by at least 2 in. If you still have a leak, pull the corner boards free and check the overlapping flashing at the corner. Often, there's old, hardened caulk where the two pieces overlap at the inside corner.

Complex Roof Problem

Complex Roof Problem

This roof leaks during the snowy part of winter and during storms in the summer, certainly due to poor flashing. The soffit that meets the roof is one of the toughest areas to waterproof. In the photo, you can still see signs of an ice dam. An ice dam occurs when snow melts and the water freezes when it hits the colder edges of your roof. Eventually, water pools behind the dam and works its way back up under the shingles and under the soffit until it finds an opening through the roof.

The solution begins with good flashing, since this should stop leaks from rainfall and might stop the leaks from ice dams as well. Begin by removing the shingles down to the wood sheathing and slip a strip of adhesive ice-and-water barrier (available where roofing products are sold) under the soffit/main roof joint. Depending on how the roofs join, you may have to cut a slot to work it in far enough. It should overlap another piece of ice-and-water barrier laid below, all the way down to the roof edge. This should cover the most leak-prone areas. Then reshingle, sliding metal step flashing behind the fascia board (the trim behind the gutter). The valley flashing, laid over the joint where the two roofs meet, should overlap the step flashing at least 2 in.

If leaks continue to occur from ice dams, consider installing roof edge heating cables. (Find them locally at hardware stores or home centers.) Improved attic insulation and ventilation are usually the best ways to prevent ice dams, but they might not be effective in this complicated roof situation.

Fix Step Flashing

Fix Step Flashing

Step flashing is used along walls that intersect the roof. Each short section of flashing channels water over the shingle downhill from it. But if the flashing rusts through, or a piece comes loose, water will run right behind it, and into the house it goes. Rusted flashing needs to be replaced. That means removing shingles, prying siding loose, and then removing and replacing the step flashing. It's that simple. But occasionally a roofer forgets to nail one in place and it eventually slips down to expose the wall. Check out this article for more on installing your own step flashing.

Don't Count on Caulk!

Don't Count on Caulk!

Rarely will caulk or roof cement cure a roof leak?at least for very long. You should always attempt a 'mechanical' fix whenever possible. That means replacing or repairing existing flashing instead of using any type of sealant. Only use caulk for very small holes and when flashing isn't an option.

Fix Small Holes

Fix Small Holes

Tiny holes in shingles are sneaky because they can cause rot and other damage for years before you notice the obvious signs of a leak. You might find holes left over from satellite dish or antenna mounting brackets or just about anything. And exposed, misplaced roofing nails should be pulled and the holes patched. Small holes are simple to fix, but the fix isn't to inject caulk in the hole. You'll fix this one with flashing.

Leaks Around Brick Chimneys

Leaks Around Brick Chimneys

All kinds of bad things can happen around brick chimneys. In fact, there are far too many to cover in this story. Flashing around chimneys can rust through if it's galvanized steel, especially at the 90-degree bend at the bottom. A quick but fairly long-term fix is to simply slip new flashing under the old rusted stuff. That way any water that seeps through will be diverted. The best fix, though, is to cut a saw kerf into the mortar and install new flashing. Get complete instructions on how to install chimney flashing.
