Curling is a condition common among old asphalt shingles. Roof replacement companies typically have to deal with curled shingles on both fiberglass mat and organic mat asphalt shingle roofs, although curling is more often associated with the latter.
Why Do Shingles Curl?
Shingle curling is an obvious sign of damage. Often, the reason behind it is traceable to the attic instead of the elements the roof is exposed to outside. When an attic lacks ventilation and insulation, heat, which naturally rises up, is trapped, making the attic temperature rise. Superheated attics can reach up to 150 degrees on a summer day.
Heat like that can make your home uncomfortable. As for the roof, the shingles are exposed to heat from the outside and baked by the heat trapped in the attic. Over time, shingles will start to curl.
New shingles are not likely to curl, but all that punishment can considerably shorten their life span. Old roofs are more prone to curling.
It’s inadvisable to walk on a roof with curled shingles. From a roof that’s due for replacement in the near future, it can quickly become a roof that’s due for replacement immediately if you delay action.
Addressing Attic Overheating
You can discuss this problem with home insulation contractors. While you can install fans that can help cool down your attic in the meantime, you should already consider redesigning your attic vents. Professionals know how to do this without exposing your roofing system to leaks. As long as your attic stays too hot, you might have to keep replacing the roof.
Shingle curling is never a good sign. Repairing the shingles might not be a great solution, as you might be throwing away money. It’s better to start planning for a roof replacement and for a way to address that superheated attic.
