Liquid RV Roof Repair & Fix RV Leaks

Download Liquid Roof Brochure

Liquid Roof is a specially formulated version of Liquid Rubber that has the flexibility needed for vehicles that are traveling and causing significant amounts of tension as it travels and turns. If your RV is stationary the entire year you can order the Liquid Rubber but if you do travel with your RV you will need to purchase the Liquid Roof. Note applying the Liquid Rubber over an RV will void its warranty.

Liquid Roof is a liquefied version of a synthetic rubber typically referred to as EPDM. The letters EPDM stand for ethylene, propylene, diene monomer and M class. Prior to the liquefied version emerging on to the market, rolls of the rubber were used for waterproofing roofs. The liquids are much easier to apply. Can fill cracks and crevices. Liquid EPDM can go where the sheet version could never effectively coat. The liquid roof coatings have more uses. They can be used on RV roofs and other vehicles. They can be applied to a wide range of roofing materials including metal, fiberglass and wood (although wood is not a warrantied application and require the use of the ProFlex primer first). Always consult your roofer to determine if aftermarket coatings are acceptable given the condition of your overall roof. The use of an undercoating means the liquid roof can be applied to built-up and asphalt-based coatings (with the use of the ProFlex primer).

Acceptable roof types for the liquid RV roof

  • Various Metal Roofing systems
  • Weathered Aluminum
  • Weathered Copper

EPDM Roof coatings are aftermarket products designed to extend roof life. Can seal roof leaks, or provide a heat-reflective or aesthetic roof-coating function over existing roof surfaces.

A True Liquid EPDM Rubber

Liquid Roof is a true EDPM rubber, and is the only one sold in liquid form. It makes installations easy. It can be described as a liquid version of the single-ply EPDM membrane that has established an outstanding performance record spanning more than 30 years. The EPDM chemistry has two unique features not possessed by any other rubber: It is unaffected by ultraviolet radiation and ozone and it can tolerate continuous exposure at temperatures above 300° F. The latter feature is also what gives EPDM rubbers the best aging properties of all elastomers (they retain flexibility longer). The shelf life of the products are 6 months. We are not responsible for product that is not stored in room temperature or past the shelf life.

ProFlex Primer

IMPORTANT: ProFlex primer is required for any RV roof where someone has put a 3rd party coating/sealant over the original roof. The primer will ensure a suitable surface for the Liquid Roof. Also owners of Fleetwood units need to apply the primer due to Fleetwood’s Alpha roof membranes. Fleetwood was popular for Alpha membranes. If you are unsure of what is on your roof we highly suggest applying the primer. When using the ProFlex primer only mix half of each part. For the gallon set part A and part B is enough for 200 sq. ft. Note when applying the Liquid RV Roof be sure the primer is still tacky. Do not permit the primer to fully cure as this will result in you needing to sand the primer to allow for adhesion of the Liquid Roof. The primer should be tacky to the point of being able to walk on it without picking up any of the material on the bottom of your feet. The manufacturer offers a warranty when liquid roof is used in conjunction with ProFlex primer.


This is a one coat system for your RV. The result is customers saving labor costs and material costs since many of the other systems on the market require multiple coats and provide no warranty. Stop recoating you RV after just three years with elastomerics and acrylics and get the product with the industry's leading warranty. Over a 26 year history of proven success in the marketplace. Regarding dry times; it normally takes about two days above 50 degrees for the material to develop a skin and then 7 days for a full cure. Should the temp drop below 50 you would need to add that time to the overall cure. So for example if it drops below 50 degrees over the next 15 hours add 15 hours to the overall timeframe. The higher your daytime temperature gets the quicker the material will dry. If you get an unexpected shower no need to worry. Also in the event of that unexpected shower the product is already waterproofed. In fact that ponding rain water will even start curing underwater! Easily applied with a squeegee and a roller a 24 ft unit should take you approx two hours to apply. Note that once you mix the catalyst you have approximately a 3-4 hour pot life depending on your daytime temperatures. The higher the temperature the less pot life you have. During your initial cleaning of your RV you may wish to consider adding 2 cups of bleach to kill any surface mold/mildew along with a standard detergent such as dawn dish washing detergent or Simple Green. You will want to be sure that any oils or fats are removed as they will cause the existing epdm roof to swell. That swelling most of the time will go down but in some cases it will not and that is not covered under warranty. Applying one coat of the proflex primer will alleviate that issue.
