A Semi Annual RV Roof Inspection Helps Prevent Leaks

A semi-annual RV roof inspection should become a regular part of your maintenance routine. Here you can learn about the things to look for and repair.

There are some differences depending on the type of roofing material. Older roofs were constructed of sheet metal or fiberglass. If you have one of the older vehicles, you should inspect the seams around anything that protrudes from the roof. Examples include vents, antennas and pipes.

The seams should be sealed using a sealant created specifically for this purpose and for this type of roof. Sealing and resealing on a regular basis reduces the risk of leaking.

You should not seal the area around a rooftop air conditioning unit because the condensation drains are located beneath the unit. If you seal around this area, the condensation will leak into the interior of the vehicle.

Newer RVs will have either TPO or EPDM rubber roofing. TPO is said to require no semi-annual cleaning or treatment but the roof should still be inspected for signs of wear. The seams of the material and the entire roof can be sealed using products specially formulated for use on TPO. The sealants may extend the life of the material.

Liquid EPDM rubber roofing manufacturers recommend a semi-annual inspection at a minimum. Some manufacturers recommend quarterly inspections, when the seasons change. Special cleansers, sealants and liquid rubber coatings are available for EPDM roofs. No silicone or petroleum-based products should be used on EPDM.

Liquid roof and EPDM rubber roofs for RV repair should also be treated with a UV blocker to prevent chalking. Liquid Rubber is the best solution for this purpose. It will resist chalking for years once it has been applied.

Regardless of the type of roof, the main purpose of the inspection is to check areas that are prone to leak and make any necessary repairs before leaking occurs. You should inspect all seams and any previously caulked or sealed areas on your RV roof.

The vent covers should be inspected on all RV Roof. Any cover with a dull finish or a brittle appearance should be replaced before you head out on the road. They may seem stable while the vehicle is parked. But at highway speeds they can break apart.

Remember to check the rubber roofing on your RV roof of any slide-outs while you are at it to look for cracking, holes or other signs of wear. Slide-outs are common leak locations. Some of the seals can be caulked using silicone. Check your owner’s manual to be sure. EPDM rubber is one of the best solution for your RV roof repair.
