Techniques For Repairing Roofs

Roof repair is a common and relatively straightforward task. However, before repairs can take place, you must find the problem areas. These are typically around plumbing, roof vents chimneys, or any construction that projects through the roof.

Often, they are caused by poor flashing or a deteriorating roof. Fixing them is a matter of removing the old flashing, bending, and replacing it. You can learn more if you click here at

Whether they are missing, cracked, or torn, shingles are the most visible sign of roof damage. You can make an emergency repair with roofing cement and a hammer, but the best solution is to get on a ladder and replace the damaged shingle. Before you start, take safety precautions, such as using a sturdy ladder and having someone at the base to help steady it.

Replacing a single shingle is fairly easy. A flat pry bar is all you need to break the black, self-sealing strip that holds the shingle in place, and once the nails are dislodged it should come up easily. For an extra measure of security, you can also use a pry bar to loosen the shingle above it as well, if the damage extends up into that area of the roof.

When a hole is in the roof that’s not caused by a missing or torn shingle, the first thing you need to do is remove any protruding nails and then scrape away any old cement underneath the shingle. If the shingle is rotting or severely degraded, it may need to be replaced, but most minor cracks and splits can be filled with a good roofing sealant.

Leaks can come in where the roof meets the walls and dormers, so be sure to check with a putty knife for areas of caulk that appear cracked or corroded. These are often the source of water dripping into the house during hard rains.

A 12-by-12-inch piece of galvanized sheet metal roof repair flashing is the easiest solution to fix a leaky spot where the roof meets the wall or dormer. Obtain it from a home improvement center and slip it up under the shingle directly above the hole in the roof. If necessary, use a pry bar to loosen a nail on the shingle above, then pull up that shingle and slide the flashing in place. Fasten it with roof nails, such as 6d galvanized roofing nails, and cover the nail holes with more sealant.


Flashing is a protective tie-in material that prevents water damage at joints and intersections. It’s a thin metal strip that comes in a range of materials, including copper, aluminum, galvanized steel, and lead. Often, it is customized for each project by being fabricated into the shape and profile that’s needed at that point. It can be found in a variety of places in your home, including around chimneys, skylights, walls, and roof protrusions.

It’s installed at points on a roof that are prone to leaks, such as valleys, where two different slopes of the roof meet and joints between structures like skylights, vents, and chimneys. The purpose of flashing is to redirect rainwater and other precipitation away from those areas, towards gutters, or off the roof. It also helps to reduce the risk of leaks by adding another layer of protection in those places.

A skilled roofing contractor can usually tell when the flashing needs to be repaired or replaced. A few signs of faulty flashing include lifted shingles that aren’t secured properly, or rusted and corroded sections that are no longer protecting the walls. It’s important to repair or replace a damaged section of flashing as soon as possible to prevent further water damage.

There are a few different types of flashing, including exposed and concealed. Exposed flashing is typically made of sheet metal, while concealed flashing may be made of a wide range of materials including plastics, rubber, and bituminous-coated fabrics. Most of the time, flashing is a continuous strip that runs across joints and intersections, but there are also instances where flashing is shaped into specific profiles that are used to direct water in certain ways.

For example, step flashing is a type of flashing that’s commonly used for walls and chimneys. This is a method that involves installing squares of flashing that overlap, similar to shingles. It’s a popular option for chimneys because it prevents water from seeping under the chimney. It’s also sometimes used for skylights, as it can be custom-formed to fit the structure and protect against leaks.


Membranes, whether a single-ply elastoplastic like EPDM or a TPO, provide the base waterproofing layer for flat roofs. They offer a wide range of benefits for commercial property managers, including low maintenance and lifecycle costs and a high level of performance in varying weather conditions.

Membrane roofing systems also come with the advantage of being easy to install and repair. This makes them a popular choice for buildings with limited space to accommodate the heavier equipment and materials required to do a torch-down bitumen job. Liquid-applied membranes are typically used to repair or recoat existing roofs, but they can also be installed on new construction with complicated shapes, details, and penetrations, as well as serving as the base waterproofing layer for intensive green roof applications.

Unlike rolled membranes, liquid-applied systems form a monolithic membrane with no seams and strong adhesion to substrates and insulation materials. They also resist cracking in aging and UV exposure much better than rolled membranes.

As with any system, routine maintenance and regular inspections are key to preventing serious problems and costly repairs. Identifying and correcting loose fasteners can prevent leaks, while a spring and autumn cleaning can ensure the roof is ready for the two most extreme weather seasons.

A common area for leaks to develop on a membrane is where the underlying insulation has been depressed, such as by foot traffic or heavy equipment from third-party vendors. Regular inspections can help identify these issues and prevent them from causing serious damage to the membrane or the interior of the building.

Once the leaks are repaired, a surfacing can be applied to provide protection and a decorative finish. The surface material can be as simple as a coating or an aggregate that shields the membrane from the sun’s UV rays and adds an aesthetic appeal to the roof. The type of surfacing chosen should be based on the roof’s long-term exposure and any manufacturer warranties.

The surfacing can be colored to match the look of the existing roofing materials. Alternatively, it can be treated to increase its reflective properties and improve energy efficiency. Infrared and electronic leak detection testing are also available to find the location of leaks quickly and effectively.


Insulation is material designed to prevent heat or sound from being transferred between areas. It usually incorporates materials that consist of millions of tiny pockets of air. The trapped air helps to give most types of insulation their high thermal resistance. Insulation can be installed in many different ways. It can be blown into place with special equipment or poured in. It can also be fitted between studs, joists, and beams. It is most effective in framing that is at standard spacing and relatively free from obstructions. It can also be sprayed into the nooks and crannies of walls and other surfaces.

The best type of insulation for your home depends on the climate where you live. Different regions require different R-values to help conserve energy and reduce utility bills. A general rule of thumb is to aim for an R-value between 40 and 50.

When installing insulation, professional roofers will wear the appropriate personal protective gear, depending on what kind of insulation they are working with. If the professionals are using fiberglass insulation, for example, they will probably wear face masks and protective clothing. Fiberglass is an effective insulation material, but it can irritate your lungs and skin. It can also be messy.

Other forms of insulation include cellulose, which is made of recycled paper and other natural materials, rock wool, a mineral wool material, and XPS or expanded polystyrene (EPS), a rigid foam board. XPS insulation can be used under a variety of single-ply roofing membranes and is a good choice for hot or cool climates because it is moisture-resistant.

It is important to install the right type of insulation because a leaky roof allows moist air to penetrate the structure. This not only reduces the R-value of the roof but can lead to mold and mildew. If these conditions are not addressed quickly, they can damage wall and floor coverings, wood framing, ceiling tiles, and other building components.

Insulation can be expensive, but it can help to save on energy costs. By reducing the amount of heat that is lost through your roof, you can cut your heating and cooling bills significantly. In addition, insulation can help to reduce condensation on the inside of your home and reduce the risk of mold and other health issues.
