The Best Products to Fix RV Roof Leaks

Repairing a roof leak properly can ensure that your RV does not suffer from further damage. While temporary solutions like silicone or duct tape may suffice for a short period of time, permanent solutions have become rather affordable and easy to find. There are many products available. However, the following items are the best option when you have a roof leak in your RV.


EternaBond is used by more than 25 top-notch RV manufacturers. It is also used by a number of RV repair technicians for roof leaks. This product can be used for the yearly resealing that is required on your RV. Its design ensures that it can withstand the test of time against UV rays. It has a built-in primer, reducing the work you have to do and provides a watertight seal so that the job is done right the very first time. EternaBond can also be used for a variety of other settings. It is suitable for repairing rips, open seams and tears for nearly all types of roofs, including concrete, tile and wood.

Liquid Rubber EPDM

In some cases, roof leaks are caused by worn caulking around fixtures like refrigerator vents, skylights and plumbing vents. Holes are made in the roof of the RV to install these items and then caulked to prevent leakage. However, after prolonged exposure to temperature fluctuations, moisture and UV rays, the caulking starts to wear. Liquid rubber is easy to apply, has a slow cure time and provides a water-resistant coating to your RV roof.

PolyScrim Roofing Fabric

PolyScrim roofing fabric is manufactured by EDPM to be used in conjunction with liquid rubber coating. This product reinforces the coating along the RV seams and other high stress areas. The benefits to this product include a good resistance to cracking or splitting as well as a dimensionally stable product. PolyScrim also conforms really well to flashings, transitions, and parapet walls.

SeamStich Buytl Tape

SeamStich Buytl tape can be used for repairing seam leaks on the top of your RV. The tape is pressure sensitive and provides a quick, watertight solution. It uses a Dupont Sontra fabric backing and contains no harmful VOCs. It has the ability to withstand extreme temperatures and provides excellent adhesion. Buytl tape comes ready to use. It uses a very simple peel and stick method. However, you should not remove the tape after it has been applied. This can cause damage to the roof of your RV. Slight wrinkling should not affect the seal. If you apply a piece accidentally, just leave it there.
