STOP - 4 Things Every RV Owner Must Know About Their Roof

1. Does the product you're applying need a Primer? Most RV Roof products do NOT stick well to EPDM Rubber Roofs without a Primer. RV Flex Repair Products do not require a Primer for EPDM rubber roofs, Metal/Aluminum or Fiberglass.

2. Are the products you're applying compatible with each other? Most products do not work with different products. RV Flex Repair products are compatible with each other.

3. Are the products you're applying waterproof? Most RV roof coatings are not waterproof and state in their fine print that it cannot handle ponding water. RV Flex Repair 100% Silicone Coating is completely waterproof.

4. Is there a warranty that comes with your produts? RV Flex Repair products are the only RV Roof Products that come with a warranty, let alone a Lifetime Warranty!

  • Is your RV Roof getting tired?
  • Ready to restore or repair your RV, Camper or Trailer Roof?
  • Need a lifelong solution? Our RV Roof Sealant is what you need.

RV Roofs have a limited life before they need to be replaced.  Generally it's on average every 10 - 15 years.  This typically costs approximately $3000 - $4000 each time unless you know the secret to restoring your roof once and for all at an average lifetime cost of about $549.95 with our RV Roof coating.

Are you asking yourself how is this possible?

It's possible with new technology that has been developed recently in the RV Roof coating world which allows 50+ year performance.  RV manufacturers who build RV's are not concerned about how long your roof lasts, they just want to make sales and have it last long enough so they don't get any warranty recalls.  Plus, if they offer RV Service centers, they make a killing servicing your RV year after year.

Now why would you want to dish out $10,000 over the life of your RV when you can Do It Once for about $549.95 with our RV roof sealant and have it Guaranteed for the life of your RV?  

I didn't want to either and that's why I developed the only RV Roof Coating that is guaranteed for the life of your RV.   Read MY STORY for full details.


All you have to do is:

  1.   Clean the surface well.  Acetone works as a good final wipe
  2.   Cut the top and puncture the inner seal
  3.   Apply the caulking over clean, well adhered old caulking (no silicone)
  4.   Final Coverage - 25 linear feet per 10 oz tube


  • Works on EPDM, Metal, Aluminum, PVC, Kynar, Wood, Concrete, Fiberglass
  • Can be applied in wet or dry conditions
  • Curing depends on humidity, temperature and airflow
  • Caulking is a moisture cure product
  • Non-hazardous.  Use outdoors and indoors
  • Paint or coat over in 24 - 48 hours
  • Apply in 35F/2C temperatures and rising
  • Roughen/Sand smooth (fiberglass), plastic surfaces before applying
  • Adhesion increases over time
  • Store in low humidity, cool environment
  • Shelf Life - 2 years
  • 100% Lifetime Guarantee

It's a great idea to always keep a tube of RV Self Leveling Caulk on hand for when issues come up.  You don't want to get caught without it when you really need it.  It's also a great gift for your fellow campers.

This stuff is amazing, it is so easy to apply, I would recommend an extra case of this if you are buying the kit. I will be applying this every couple years because it appears to be working so well and so easily.
