Tips For Repairing And Preventing Roof Weather Damage

No matter what part of the country you live in, there can be different types of weather patterns that will affect your home's roof and shingles. After an extreme storm or a cold and snowy winter, you should check your roof for any damage to have it repaired as soon as possible to prevent moisture from getting into your home through the damaged roof. Your roof is one of the most important barriers to your home's integrity, and here are some tips to help you repair and prevent some types of weather damage.

Repair Wind and Hail Damage

If you have not experienced a hail storm with considerably-sized hail stones that can do damage to your home and roof, consider yourself lucky. Hail stones falling upon your roof can cause damage to a shingle's structure and its  surface's protective covering. Because hail stones are not all smooth and rounded, they can have sharp edges and exterior bumps that can cause damage to your roofing materials as they fall and are blown by strong winds onto your roof. 

Hail damage to your roof will appear as randomly spaced spots where the shingles are missing their texture or you can see the roofing felt through a hail-sized hole. Hail stones can cause bruising to the surface of your asphalt shingles, causing the shingle to become softened and to lose its protective granular coating. Sharp-edged hail stones can cut into the surface of the shingle and split it apart, allowing moisture to get through the shingle to the roofing felt. Extreme wind storms can also cause your roof to lose individual shingles, sections of shingles, or shingles that have become lose and are flapping up and down.

Safely get upon your roof after a storm and after your roof has dried to look for any damage to your shingles. You can also hire a professional roofer to inspect your roof for the extend of the damage, and replace the missing or remove and replace individual damaged shingles. Keep in mind it may not be necessary to replace the entire roof.

Be sure you or the roofing professional checks your roofing materials below the shingles to look for any moisture damage. Moisture damage can require you to remove and replace the roofing felt and also the roofing deck below. When the plywood roofing deck becomes wet, it can warp and grow moisture rot, which will require it to be replaced. After the shingles have exposed the below layers of your roof, they can become wet and damaged from the moisture and need replacement.

Repair and Prevent Ice Dam Damage

Ice dams can occur during the winter if you live in a northern climate and receive snowfall. As snow accumulates on your roof, any heat escaping through your roof from your home can cause the snow to melt and flow down to the cold edges of your roof where it freezes into a layer of ice. The problem with this is overtime the ice grows thicker and begins to form beneath your roofing shingles causes moisture to get into the underlayers and decking on your roof. Each time water accumulates around your shingles to freeze and expand, it separates your shingles further apart and causes more damage.

Preventing the formation of ice dams requires you to keep your roof cool by blocking heat escaping from your home and warming the roof. Safely gain access into your attic and seal up any gaps around electrical and ventilation openings that may allow heat from your living space to enter. Use caulk or spray foam to seal these gaps. Also check your insulation to make sure it has not shifted or is exposing any bare attic floor, which can allow heat from below to enter. Replace and supplement any inadequate insulation levels, or hire a professional to complete this task.

Make sure your attic has enough ventilation to keep your roof cool, allowing cold air inside and warm air to escape the attic.  It is recommended to install one square foot of vent area for every 150 square feet of attic floor space. You can talk to a roofing professional to help install any additional roofing vents.
