Crystal-Clear Roof Sealant

DAP Ultra Clear is a 10.1 fl oz elastomeric synthetic rubber sealant designed for homeowners and contractors who need an invisible, waterproof barrier around roof fixtures and penetrations. It stops minor leaks and prevents moisture damage while blending seamlessly with existing substrates.

Wet-Surface Application Limits

The sealant adheres to wet, damp surfaces and even through standing water, functioning in temperatures from 0°F to 120°F. It cannot bridge structural gaps or replace flashing on active, high-volume leaks that require mechanical repair rather than a surface-applied coating.

Permanent Flexibility Decides Suitability

The formula stays permanently flexible and crack-proof in cold temperatures, resisting UV yellowing and breakdown over time. Buyers needing a rigid, paintable patch or a sealant for non-roof substrates such as plumbing joints should choose a different product type.
