What is Caulking?
Roofing Glossary · Maintenance
Definition
The application of a flexible sealant compound to fill gaps, cracks, and joints in roofing and flashing systems. In roofing, caulking is used to seal the edges of counter flashing, fill small gaps around penetrations, and supplement mechanical seals. Roofing-grade polyurethane or rubberized asphalt caulk is required — general-purpose construction caulk lacks the UV and temperature resistance for roofing applications.
