Asphalt roofs are extremely common, and many roofing installation experts and shingle manufacturers guarantee a 15 to 30 year lifespan for their shingles. If your roof is already more than 15 years old, then you may start to see some shingle damage. There are a variety of different types of damage that may be apparent. Keep reading to learn about a few types and how the shingles can be fixed until you decide to have a completely new roof installed.
Cupped shingles are ones that have started to pull up around the edges to leave a concave cup in the middle of the shingle. Cupping can sometimes occur due to age and wear. In general, cupping occurs when shingles are exposed to cold temperatures over the course of many winters. Cold temperatures cause the shingles to shrink, and the shingle mat will pull up a small amount from the bottom of the shingles when this happens. The shingle mat will typically flatten down when the warm temperatures hit the shingles during the spring and summer months.
Over time, shingles will lose some of their flexibility. When this happens, the mat will no longer flatten out. The shingles will appear more and more cupped over time. If the cupped asphalt shingles are still somewhat pliable, then you can use an adhesive to secure the raised areas of the shingles. You will need to test the shingles first to make sure they do not crack as they are flattened.
Climb on your roof and use your hands to force the edges of the shingle down. If the shingle flexes and bends without cracking, then purchase a tube of roofing cement. Roofing cement is an all-purpose adhesive that contains asphalt, mineral spirits, reinforcing fibers, and plasticizers. Place a thick layer of the cement underneath the raised portions of the shingle and press the shingle down.
If your asphalt shingles have cracks along the edges, then this is often a sign of thermal splitting. Thermal splitting occurs when the heat of the sun causes the shingles to expand. When shingles become old and less pliable, the expansion causes the top asphalt surface to crack and split. One or several cracks can form in the shingle when this happens. Typically, shingles that are exposed to the most sun during the day will form the cracks.
Cracks can be patched with the same type of roofing cement that is used to secure cupped shingles. To make the repair, gently pull up the shingle and place a bead of cement underneath the crack. Press the shingle down into the cement. Allow the cement to dry for about 24 hours. While you wait, go to your local home store or roofing supplier and ask for a small bucket of roofing granules or minerals. These are the small rocks that you see on the top of your asphalt shingles, and they help to reflect the rays of the sun. This solar reflection will help to reduce thermal splitting issues after your initial repair is made.
After you purchase the granules, place a small amount of roofing cement over the shingle crack. Smooth out the cement and sprinkle a generous amount of the granules over the cement. This will help to secure the granules to the damaged shingle.
Roofing shingles will wear over time and require replacement. In some cases, you can extend the life of your roof by making some minor repairs. Cupping and cracking are two types of damage that can easily be repaired. If you do not feel confident about making the repairs yourself, then contact a local roofing repair expert from a company like All American Roofing Incorporated to make the fixes for you.Share
