RV Rubber Roof Repair: How to Locate a Leak


It is  important to take up any RV rubber roof repair urgently, as any leakage can be destructive. A small unnoticed roof leak can slowly spread out to both walls and the floor structures.

RVs are provided with durable rubber roofs, but they may get punctured with sharp objects. The roofs have plywood or metal sheets underneath the rubber coating. The roof plies or metal sheets are seamed together in several places. If the rubber is punctured or cracked, water can seep underneath the rubber and leak through the seams.

The inside water stains may not indicate the exact location of leakages. You need to carefully examine the roof to locate the leakages from their point of entry.

Materials and Tools

  • Works Horses
  • Planks
  • Repair Kit

Step 1: Observing stains on Walls and Ceiling

Scan the ceiling and walls to look for any water stains. If there are stains, there are leaks in the roof. You need to inspect the roof from the top to find the points of water entry.

Step 2: Getting to the Roof

Get to the roof of the RV. Please ensure before getting to the roof that there are adequate supports provided in the roof to withstand your weight. You may need to use the work horses for side supports and put planks on them to check and repair the roof in such cases. In other vehicles you can walk on the roof without fear.

Step 3: Inspecting the Roof

Check for any major damages on the roof. Particularly observe the front and rear of the roof.

Keenly observe the areas around A/C units mounted on the roof and all other vents provided for gas, air ventilation, refrigerators or any plumbing fixtures.

Another source of leaks can be low areas in the roof where there are dents, cracks or cuts in the roof rubber lining where water may accumulate or enter. You may find dirt rings at those spots. Check those cracks, splits or holes. Once you have located the leaks, you can repair these points.
