Using this specific product

Sashco Through the Roof! Roof & Flashing Sealant is listed here as the Clear and colors version for roof, flashing, and gutters. For sealing a joint, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Clear and colors; related versions can use different timing.
  • For roof, flashing, and gutters, pay particular attention to joint depth, tooling, ventilation and exposure to water.

How to check readiness

Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. Tack-free: 30 minutes (ASTM C679). Can be painted or stained with latex-based coatings after 24 hours. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Surface skin is not the same as through-cure, especially in a deep joint.
