Asphalt shingles are ubiquitous. If you’ve ever owned a home then you’ve had them on your house at one time or another. Asphalt shingled roofs have been in use in America since 1901. They are durable for the price, affordable and come in many different textures and colors. Face it, we Americans love them!
In this tutorial lets take a look at some of the actions you can take to check and repair your asphalt shingled roof when it is near the end of its life. A great idea is finding a roofing repair pro using a company like HomeAdvisor which you can use as a resource to find a roofing contractor in your area. They have an idea of what issues to watch out for and how to repair them, and have provided some tips.
Problem #1: Curled Asphalt Shingles
Over time, asphalt shingles begin to curl upwards or downwards (curling, cupping, clawing) as a result of improper installation, age or environmental conditions. This is a serious problem and will require a roof replacement. A buckling shingle may be caused by the roofing installer not laying down a roof underlayment (roofing paper) on top of the roof decking. The lack of underlayment will cause moisture problems to the shingle and roof boards / decking.
You can sometimes repair this problem for a short while gluing the shingle down with a bituminous roof sealant in caulk tube, but it’s not a permanent solution. You’ll use a caulking gun, apply some roofing sealant to the curling shingle and push it down. You’ll then weigh it down with a brick for at least 24 hours. It’s best to do this kind of repair in warm weather, to ensure the glue actually sticks to the structure and doesn’t pop back up. In cold weather, shingles become more brittle; you run the risk of breaking the shingle when trying to curl it back down.
As asphalt shingles age you may see them start to curl and cup because of sunlight, moisture and changes in climate conditions. While you can repair some of them, it may be time for a new roof. You can only delay the effect for so long by gluing them down, so don’t wait until it’s too late to replace your roof.
Some steps you can take to extend the life of your roof and prevent curling include:
- Adequate roof ventilation (inadequate ventilation also a cause of ice dams)
- Dry conditions (e.g., getting snow off the roof during the winter)
- Consistent temperature whenever possible
