If you live in an area near a lake or ocean or if you are in a designated hurricane area, then you probably are used to high speed winds hitting your home. If your house has an asphalt roof, then you may have seen some of the wind damage in the way of broken and dislodged shingles. These areas of damage need to be repaired by professional roof contractors from companies like Acoma Roofing as soon as possible. After the new shingles are applied, make sure your roof is resistant to the wind. Keep reading to find out what you are able to do to minimize the effects of the wind.
Add a Protective Coating
Sometimes, asphalt shingles are just not strong enough to remain secured against your roof when strong winds hit them. This is the case, because tropical storms produce wind speeds up to 73 miles per hour, while hurricane winds can reach 157 miles per hour. Unfortunately, your roof may not even be able to withstand 90 mile per hour winds if class D shingles were installed. If class G shingles were added, then they can endure 120 mile per hour winds, and class H shingles are capable of holding strong if winds reach 150 miles per hour. Even if you have class H shingles, they still might not be strong enough if they are old or if they were not initially installed properly. However, you can create strength and greater endurance against wind regardless of shingle class by adding a protective coating over the shingles.
One of the best protective coatings you can add to your roof is an acrylic sealer. The sealer is made out of a polymer material that is sprayed on top of the roof. The coating creates a membrane that is typically between 15 and 30 mils thick. The sealer works its way into cracks and openings to fill them in, and it sits on the surface of the shingles too. This helps to force the find away from the roof instead of allowing it to pick up shingles along edges and corners.
Secure Your Flashing
If the shingles on your roof have recently been fixed or replaced, you may have forgotten to inspect your flashing. Flashing consists of the aluminum or galvanized steel pieces that sit on roof joints, around vents, and next to chimneys and roof edges. The material is meant to direct both wind and water away from unprotected sections of the roof so leaks and other types of damage do not occur. Unfortunately, if the flashing is loose or bent, then it can direct high-speed winds downward where it can damage the asphalt shingles in the area.
Fixing Loose Flashing
To prevent this from happening, inspect your flashing thoroughly. If flashing is loose, but not bent or otherwise damaged, then consider reattaching it to the roof. Flashing is usually secured with roofing nails. Shingles may sit over the flashing as well, so peel up these shingles gently and use the claw end of a hammer to loosen the nails. Lift up the flashing a small amount and place a bead of polyurethane flashing sealant around the bottom edge of the metal. Make sure a small amount of the sealant fills in the old nail holes. Afterwards, measure one half an inch from the edge of each old nail hole and drive new nails in the flashing. This is best to make sure the nails are as secure as possible. The nails will likely be loose if they are set in the old holes.
When you are finished, spread a small amount of the sealant underneath the shingles you pulled aside. Set them back in place and make sure they are secure. You can complete the same process if the flashing is bent. However, you will need to use a new piece of flashing to replace the bent one.Share
