Why is it better?

Fiber Infusion

The Crazy Seal Roofing System was designed from years of research and testing across thousands of flat roofing applications. Combining several strength enhancing roofing systems into one unique and proprietary formulation, we were able to create a suite of products uniquely effective in solving your roofing problems.


Crazy Seal is the only silicone coating system on the market that uses Polyethylene fibers in its product. It makes whatever it’s applied to stronger. Think what rebar does to concrete. In the past, this has traditionally been a drawback to silicone coatings and a major concern for RVers where contact with tree branches are commonplace. In other words, it adds additional strength, durability and even scratch resistance.

Fiber Infusion

More Actual Silicone Content

Unfortunately, many big box brand coatings use cheap fillers to increase their solids content on their coatings to lower their product costs. This results in less overall silicone by volume. While incorporating cheap fillers can help keep prices low, it comes at the cost of reduced performance and longevity. Here at Crazy Seal we will never lower the quality of our ingredients simply to produce a cheaper product. We source our silicone and silica based ingredients from the same suppliers that supply the pharmaceutical industry to guarantee the quality and performance of our ingredients. That means the tightest tolerances, and we put more of the good stuff in our products. We do not use cheap fillers, etc.

Other Silicones

Crazy Seal


Cheap coatings often are not much more than glorified paint, and at best, only offer a temporary solution. Often, you the buyer are not aware of the negative repercussions of using low grade products and end up in a loop repeating the process over and over again. As Crazy Curtis our Mascot says, “If you buy the best, you only cry one time!”

21½ Reasons Why

Forged from the knowledge gained from thousands of flat roofing installations, we developed the Crazy Seal system with you in mind. 


A system is only as good as YOUR ability to install it! Years of trial and error went into making our system extremely strong yet simple to apply.

Why does Crazy Seal succeed where others fail?

We Support & Care About Our Customers

We have a suite of instructional materials, and have experts on hand to help assist you in making your project a success. 

3 Part Sealing System

Our 3-part sealing system actually stops leaks! Simply applying a membrane to your roof doesn’t necessarily “seal the deal”. Our system focuses on eliminating your problem areas first, then finalizes the sealing process with our final membrane! This ensures you actually solve your problems and eliminate leaks where they are most likely to occur. All components are derived from the same base formula and merge seamlessly together into a single membrane. The end result seals all penetrations and fortifies your roof with a seamless, custom fit membrane covering every square inch of your roof.

We Are One of a Kind

Why Crazy Seal For Your Roof?

Our multi-component system flips the roofing equation upside down.




Traditional Roofing

The application of our system completely flips the roofing equation upside down. In typical roofing, you have a substrate like rubber, epdm, etc. that is laid down first with adhesive. Roof components are then installed on top of this substrate with screws, tacks, and nails creating hundreds of potential leak points. Then a layer of sealant is applied on top of the penetrations. At this point, the only protection over those penetrations is that layer of sealant, which over time can rot or deteriorate, leaving your roof vulnerable to water intrusion.

Water Intrusion Examples

Deterioration leading to water intrusion can be incredibly destructive to your vehicle and everything inside. Here are a few examples of how much damage water can do.

The Crazy Seal System

Crazy Seal does exactly the opposite! Our system begins first by using our specially formulated caulk and mastic to seal all seams and penetrations. From there a final membrane is applied on top of the sealed penetrations. The entire roof is now sealed under one giant chemically bonded molecule.
All components are derived from the same base formula and merge seamlessly together into a single membrane. The end result seals all penetrations and fortifies your roof with a seamless, custom fit membrane covering every square inch of your roof. See the before and after sliders below to see how Crazy Seal creates a seamless membrane on every inch of your roof.

Much of the cost of a typical roofing installation comes with labor. Do it yourself and save big with raw materials factory direct from Crazy Seal!


Hiring a roofing technician can take several weeks or even months. With Crazy Seal, you can have a brand new roof within hours of receiving your kit.



If it’s worth doing, it’s worth doing right. Rather than putting a bandaid on a problem, do it right and do it once with the Crazy Seal roofing system.

Fire Department Saves $39,000. Their review says it all.

The Town of Emerald Isle Fire Department recently sealed the roof of a 24’ emergency response rescue trailer. The EIFD staff completed the repairs using Crazy Seal products. Instead of spending $40,000 and waiting 12-months for a replacement trailer, town staff spent $1,000 on product. Two days later, the trailer was dry and ready to save lives along the weather impacted coast of North Carolina. Thank you to Crazy Seal and the fantastic folks that make such a wonderful product!

Thank you,

Matt Zapp – Town Manager
