Do asphalt shingles need time to settle and adhere?
Thursday, May 14, 2020
Asphalts shingles require anywhere from several days to a month of warm weather for the adhesive strips under the lower edge of each shingle to soften and stick firmly to the shingle below it. Also, if there is any minor waviness in the surface right after installation, the whole shingle will gradually relax and settle under the heat to flatten out evenly.
But any waviness in an older roof, like the one shown below, is likely due the shingles telegraphing deformation of the sheathing below them.
Sometimes, problems with installation or manufacturing will cause the shingle tabs to not set properly. To learn more about this problem, see our blog post What would cause a new asphalt shingle roof to have loose tab adhesion (sealant strips)?
