What is Hand-Sealing?
Roofing Glossary · Installation
Definition
The manual application of roofing cement or activating pressure to the sealant strips on shingles in cold weather to initiate adhesion before the sun activates the factory-applied sealant. Most asphalt shingles have a factory sealant that activates when the roof reaches approximately 40 degrees F and direct sunlight. In cold temperatures below 40 degrees F, hand-sealing is required to meet wind warranty specifications and prevent blow-offs.
