While shingles and tiles can stand up to a lot of wear and tear, they aren’t infallible. It’s common for high winds and debris to damage a roof, leading to repairs or replacement.
Whether to repair or replace is a big decision and one that can impact the overall cost of a home.
A roof’s shingles are its first line of defense against rain and wind. In general, shingle roofs don’t need much attention beyond the occasional inspection for moss and lichen, but any damage that requires repair should be handled as quickly as possible. That’s because leaking roofs can lead to serious water damage, which could result in mold growth, wood rot and other costly issues that require extensive repairs or even total roof replacement.
If your shingle roof is leaking, it’s important to contact a professional as soon as possible for a roof repair or complete roof replacement. This ensures that the issue is addressed before further damage occurs, preventing water from seeping into your home’s attic and down into the living areas below.
For minor shingle roof leaks, homeowners can often reseal the area themselves using roofing cement or adhesive. But major roof leaks usually require replacing the damaged shingles.
Start by removing any shingles that are overlapping the damaged one. This will prevent any damage to the intact shingles, as well as allowing you to access the nails that secure them.
Next, slip a pry bar under the shingle directly above the damaged shingle and begin lifting it up. You may have to go a few rows down before you can pull up the entire shingle. If you discover that a nail is exposed (it will have a small strip of the glue on it) put some roofing sealant on it before continuing to the next step.
Once you’ve removed the shingle, use your utility knife to cut any notches that have been made in the surrounding shingles. This will help you slide the new shingle into place without any gaps or overlaps.
When you’re done, apply a thin bead of roof sealant (available for $10 to $20 per tube at home improvement stores) along the bottom edge of the new shingle and press it firmly in place. Be sure to also apply a bead of sealant in any area where the old shingle’s glue broke off during removal. This will ensure that the shingle doesn’t blow off during the next wind storm.
Flashing
Flashing is a thin piece of metal installed on vulnerable points of the roof, such as the areas around chimneys and skylights, or where the roof meets other structures like walls. It is designed to seal these areas, preventing water from entering the home and reducing the risk of leaks and mold.
Flashing is often made of metal like galvanized steel or aluminum, which offer durability and resistance to the elements. However, flashing can still wear out or become damaged, which can cause leaks and other problems in the home. The best way to avoid these issues is to schedule regular roof inspections and repair any damage promptly.
When flashing is properly installed and well-maintained, it creates a tight seal that prevents water from seeping into the home. However, flashing can be damaged or displaced at vulnerable points of the roof, such as where it meets other structures like walls, or where the roof plane meets a vertical surface such as a dormer or chimney.
If you notice that the shingles surrounding a flashing area are starting to lift, this is a sign that the flashing is no longer sealing correctly and needs to be repaired. Leaking at these areas can lead to water infiltration into the home, causing mold and rot.
A professional roofer should be able to identify any problems with the flashing and repair it as soon as possible. Some types of flashing require two pieces, so it is important to check and maintain these areas. The base flashing (also called apron flashing) goes under the shingles and up to the edge of the wall, while counter flashing is placed opposite to it and overlaps.
Other flashing is embedded in wall interruptions like windows, or used to protect the edges of tile roofs against water ingress. There is also channel flashing, which is often found under windows or doors, and sill flashing, which is concealed underneath a window or door threshold to prevent water ingress. Finally, there is stepped flashing, which is used where a roof meets a wall on a slope.
Gutters
Gutters are one of your roof’s best defenses against water damage. During a storm, they effectively channel rain off your roof, through the downspouts and away from your home. Without gutters, rain would likely collect on your roof and cause rot or deterioration of the shingles, fascia and soffit. It could also lead to flooding in the basement or foundation issues.
Gutters keep water from flowing under your shingles and into the house, which can damage the various waterproofing layers and cause mold and leaks in the attic and ceilings. However, if gutters get clogged with leaves, branches or debris, the water will overflow and spill over the sides of your roof, causing all sorts of problems.
It’s important to clean your gutters regularly to prevent clogging and overflow. When it’s time to clean your gutters, make sure you have the proper tools and safety equipment. For example, if you plan to climb a ladder to clean your gutters, be sure to wear sturdy footwear and take regular breaks to avoid overstretching. It’s also a good idea to hire a professional for gutter cleaning if you don’t have the proper tools or experience.
Another function of gutters is to protect the siding along your exterior walls. Without the drainage function that gutters provide, water would overflow and run down your home’s sidewalls, exposing them to moisture and allowing mold, pathogens and aggressive termites to form. In addition, weakened wall boards are more susceptible to being pecked by squirrels and other critters that seek access to the attic.
If your gutters are leaking, they may need to be re-flashed or repaired. To fix a leaky gutter, first remove the old downspout and replace it with a new one that’s the same size or larger. Then, put the downspout in place and use sheet metal screws to fasten it. If the gutter sags even with solid support, consider adding more supports. Loose hangers can be re-nailed using 6d galvanized roofing nails and covered with roof cement to prevent leaks. Also, check that all of the fascia brackets are secure and not sagging or loose.
Soffits
Soffits may seem like a minor detail in your roof’s architecture, but they play an important role in your home’s performance. A soffit is the structure that covers the underside of your roof overhang. It can be made from many materials, including aluminum, vinyl, or wood. They can also be solid panels or include perforations to improve air flow. In addition, they protect your roof from rotting and prevent moisture build-up in your attic or crawl space. They also keep pests and wildlife out of your roof space.
Because soffits can be so easily damaged, it is important to repair them regularly. Damaged soffits are not only unsightly but can allow water, snow, and other elements to enter your roof. Sagging sections, cracks, discoloration, or peeling paint can indicate that soffits need to be replaced.
Another common problem with soffits is that they become clogged, preventing adequate ventilation and encouraging mold growth. This can be caused by a variety of things, including poor installation, wear and tear over time, animal damage, and weather damage. It is also important to check soffits regularly, particularly after cleaning your gutters.
Fascia boards are an important part of your roof system, providing a finished look to your roof’s edges and protecting the board from water damage. They are also a vital component of the roof ventilation system, and it is vital that they remain in good condition. Fascia boards are usually fabricated from wood or composite material. Wood fascias can be prone to insect and wood rot damage, which is why it’s important to consider replacing them periodically with a material that is more resistant to these problems.
Besides enhancing the aesthetic of your roof, a well-maintained fascia can actually save you money on your energy bills by keeping your attic properly ventilated. Ventilation helps regulate attic temperature, preventing overheating in the summer and condensation that can lead to mold in the winter. A properly functioning fascia and soffit can even help prevent the formation of ice dams on your roof.
