So why do shingles curl?


There are some common causes that lead to curling and cupping of your shingles. When the center of the shingle is concave, the shingle starts cupping. When the sides are changed, they are referred to as curling. Common causes include aging as well as wear due to climate.

  • Bad attic air flow – Inside your house, warm and humid atmosphere usually rises near your attic. In case your attic is well-ventilated, this is not an issue because the excess moisture will probably be circulated and forced back from your attic. If not, then you will start facing issues. In case your attic is poorly ventilated, then dampness will get stuck within the decking, which will trigger mold formation, and shingles to curl consequently.


  • Improperly installed shingles – The most typical problem here is the fact that whoever set up your roof did not use sufficient nails for each shingle, or incorrectly placed the nails. In either case, this is perfect for your shingles to curl. If you do not have sufficient nails for keeping the shingles down or the nails are put in wrong spot, it will have to function over time, leaving your shingles loose.
