The Crazy Seal Roofing System
Commercial Roofing
Break the repair-repair-replace cycle.
Crazy Seal is a seamless, fiber-infused silicone system your own crew — or any local contractor — can install over an existing commercial roof, in stages, as budget allows. Every repair chemically bonds to the last until the whole roof is one permanent membrane.
While we have pre-built kits as examples, 99% of commercial kits are custom built by a professional or a specialist on our team. Tell us about your roof and we'll spec it with you — or run your square footage through the Kit Builder for a quick price estimate.
Sized & priced to your exact roof
Kits scale from a single tube of caulk to a complete system for thousands of square feet. Most commercial projects are custom quoted — staged installs let you spread the cost across budget years.

The Details That Matter
Why the System Works
Begin with a repair, go from there. The fluid-applied system lets you solve immediate problems now and complete your roof in stages to stretch annual budgets.
A few square feet to thousands. The same system scales from spot repairs to full commercial roofs — restaurants, warehouses, self-storage, and more.
Ends the repair-repair-replace cycle. A seamless, permanent silicone membrane instead of another band-aid that has to be torn off later.
50-year product warranty. The strongest warranty in the roofing industry, registered with a simple form.

ResidentialProject #5344
DIY Residential Roof That Sealed the Deal
“The product was easy to apply, and the customer service was fantastic.”
ResidentialProject #5210
Slippery Coats and Solid Results
“The first coating was challenging, the second coating was easier and slippery. By the time we got to the end and finishing up, we were slipping and sliding. It was an experience to hang on to.”
ResidentialProject #5113
Commercial Roof Revived with a Seamless Overlay
“Very easy to install.”
Straight From the Roof
Real reviews from customers who installed it themselves.
“I am an independent contractor and this stuff is different (in a good way) than anything I have ever used. I could tell by how well it adhered that it is very strong and flexible. Very impressed so far.”
Melvin Nixon
“Very satisfied. Best product ever! Would recommend it to anyone looking to be "Once & Done"”
Robert Davies
“Pretty easy install. Followed the directions exactly as prescribed and looks great. Water beads up on the roof and just sheets off now. Very satisfied with how easy it was.”
Brian Mitchell
“Very happy with the product and the customer service is second to none. All the work is in the prep. Take your time with that and everything will go well.”

How It Goes Down
No torches, no tear-off, no special tools. Three steps, guided by step-by-step videos.
1. Clean
Wash the roof with Crazy Clean so the membrane bonds to the roof — not the dirt.
2. Seal
Caulk and patch every seam, screw, and penetration with Crazy Caulk and Crazy Patch.
3. Coat
Roll on the seamless Crazy Seal membrane and never worry about that roof again.
