Inspection & Repair for Curling Roof Shingles
Curling roof shingles can happen on roofs of all ages, caused by moisture on the underside of the shingle. That moisture builds up in the attic and causes wet/dry cycles in the shingle. Most often, this is a consequence of some other underlying issue that is going on with your roof system. As the roof shingle begins to curl, it becomes weak and damaged. This makes it more susceptible to wind damage, which will cause more problems to your roof.
Fortified Roofing & Siding is here to help. Often times a roof with curling shingles can be repaired if the problem is caught early. If you suspect you have curling roof shingles that need professional repair, we suggest you call us for an inspection; it could indicate the structure has been compromised. We pride ourselves on figuring out the underlying cause and fixing it so the problem doesn’t happen again.
Understanding Why Shingles Curl
Curling shingles happen when the bottom part of the shingle is warmer than the top of the shingle. The difference in the temperature weakens the structure of the shingle, causing it to bend and curl upwards. Cause of curling shingles include:
- Inadequate ventilation: Shingles need air circulation to perform effectively. If the roof has improper ventilation, you are almost guaranteed to have a problem with curling roof shingles. Without proper ventilation, air cannot circulate or escape from beneath the shingles. When there is high temperature or heavy rain, the heat and moisture get trapped under the shingles. The heat will continue to get warmer until the upper layer begins to curl.
- Improper installation: Curling shingles are also a common consequence of improper installation. If the nails are not placed properly or the shingles were not lined up properly, it can lead to curling. Some installers drive the nail through the sealing strip which prevents the shingles from sealing together. This in turn causes the shingles to move and lift. The fluctuating temperatures over time cause the nail to pull out. This leads to the shingle separating and curling.
- Low-quality products: Shingles curl when poor quality products are chosen. When cheap shingles are chosen, they usually deteriorate faster. When choosing a roofing shingle, it is important to pick a shingle that will last and is made of high-quality products.
Other possible causes of curled shingles may be:
- Exposure to extreme weather
- Old age (20+ years)
- Multiple roof layers
