RV roof repair is essential to protect and maintain your recreational vehicle and its interiors. Rubber roofing is a relatively new and cost effective alternative to conventional metal roofs installed on recreational vehicles. Though the material from which rubber roofing is made is of the best quality, at times, branches of trees or extreme weather conditions over a period of time can damage the roof. A damaged RV rubber roof increases the temperature control costs, and allows weather elements to enter the interior and damage it. In order to avoid all these problems, if the rubber roof of your RV is damaged, follow the procedure given below to repair it.


Step by Step Procedure

Step 1 – Determine the Rubber Material

Using a step ladder, climb on the roof top of your RV. Clean the roof with a floor cleaner. The material used for rubber roofing can be of different varieties. Find out the kind of material used for rubber roofing on your RV so that if you want to carry out a patch-up work, new material should be exactly similar and compatible with the earlier material used.

Step 2 – Inspect and Measure

Inspect the roof carefully to locate the areas of leakage on your rubber roofing by poking the doubtful areas with the stick. Avoid stepping on such spots as they may collapse totally. Mark those areas and measure the area of the leakage so that you can purchase that amount of rubber material from a rubber roofing supplier.

Step 3 – Clean the Leaky Areas

Use rubber cleaner to clean the areas marked as leaky. Alternatively, benzene solution can also be used for cleaning the rubber roofing.

Step 4 – Fixing Leaky Spots

Leaking spots of the rubber roofing on your RV can be fixed in two ways. You can follow whichever suits you.  

  • Method 1 – Patch Up

    Cut new rubber sheet according to the size of the leaky spot. Apply rubber sealant in the cleaned spot and place the cut rubber sheet at that spot and press it so that it overlaps with the adjoining areas.


    • Method 2 –Roof Coating

      You can coat your RV’s roof top either with elastomeric coating or liquid roof. Liquid roof is also an Ethylene Propylene Diene Monomer (EPDM) rubber coating just like elastomeric coating that can be applied to your roof tops in order to prevent leakages or to stop leakages. Use a broad painting brush or roller to apply a thin coating on the leaky spots of your RV. After it dries completely, apply another coat of liquid roof on the entire roof to prevent any damage in future.

      Step 5 – Test the Repair

      After 5 to 6 days of the repair work, test the work by showering your RV with lots of water. Find if the leakages are fixed or not. If you still find leaking in your RV, then you will have to repeat the process once again and retest. If nothing seems to work, asking a professional's help is the only option left.
