Modern Tech Taking On an Old Challenge
Our chemical strategists and product testing teams spent years developing what may well be the strongest fluid-applied membrane ever brought to market — now patented and backed by a fifty year warranty.
For decades, there has been a huge gap in roofing
Low-grade coatings
Temporary at best
Inferior membranes
Often fail within 3-5 years
Crazy Seal
Affordable, high-grade, built to stand the test of time
High quality materials used to be available only to large roofing contractors. We've changed that with Crazy Seal! It's time to take care of the small and mid-size project.
Our Products
SeamsCrazy Caulk
A fiber-infused silicone, moisture-curing sealant with excellent adhesion to most surfaces. Seals seams — like the sides of an RV, or where gutter systems attach to the roof.
PenetrationsCrazy Patch
A fiber-infused silicone, moisture-curing mastic that ensures penetrations are sealed wherever sealant was previously applied. Also works alone as a single component repair product to patch leaks.
MembraneCrazy Seal
A weatherproof, fiber-infused silicone, fluid-applied membrane that protects any weathered roof against harsh UV rays, severe weather, mold and mildew. Won’t chalk or blister; stays permanently flexible yet strong.
RepairsCrazy Tape
Strong adhesive on one side adds structural integrity to the seam, while the fabric on top lets the Crazy Seal System adhere to it — opening up many possibilities for repair.
PrepCrazy Clean
A concentrated cleaning solution that removes oils, dirt and oxidation. Environmentally safe, non-toxic, and leaves no contaminating by-products or pollutants behind.
