Shingle curling is never normal, whether you have a new roof or an older one. It is always a sign of a serious underlying issue with your roof. Today, Mass-Tech Roofing and Building Co. explains how shingle curling occurs and what you should do about it.
1. Insufficient Attic Ventilation – A poorly ventilated attic is one of the top causes of shingle curling. When moisture-filled air and heat rise and get trapped in the decking, wood decay will occur. This can cause the shingles over the wood components of your roof to curl.
2. Poor Installation – A botched roof installation can cause a host of problems down the line, including shingle curling. If the roofer didn’t use enough nails or the right kind of nails, or if they placed the nails improperly, this can all potentially lead to curled shingles. Improperly lined shingles also contribute to curling.
3. Extremely Cold Temperatures – Extreme weather changes especially during winter months can cause roofing materials to expand and contract. This can result in shingle curling.
4. Old Age – Curled shingles can occur when the roof has experienced significant wear and tear due to old age. Have your roof replaced before more serious damage happens.
