Through the Roof Sealant

When your roof absolutely, positively needs to be water-tight (and really, when does it not?), use Through the ROOF!

Through the ROOF! is a seriously unique roofing caulk it can be applied in the rain. (No, we're not kidding.) It sticks to wet surfaces, which means you can fix the leak while it's leaking.

Through the ROOF! will stick to almost any roofing surface metal, plastic, asphalt, wood, concrete, and more. Plus, it won't freeze.

  • Elastic - flexes with temperature changes and wind
  • Ultra-clear and stays clear - will not yellow over time
  • Lasts 20 times longer than asphalt
  • Excellent UV resistance
  • Adheres to most existing roof patches
  • Paintable
  • Water and mildew resistant
  • Won't freeze
