The EPDM (Ethylene Propylene Diene Monomer) material that is used for rubber roofs on RVs protects the RVs roof, but must be maintained. If petroleum-based products are used on it the petroleum will penetrate the roofing material and cause it to bubble. These bubbles can be ignored if there are just a few scattered across the roof, but if there are many they should be fixed to prevent further damage.
Things You'll Need
- Butyl rubber sealant
- Disposable syringes
- Plastic wrap or wax paper
- Something heavy
Purchase a syringe at a drug store. You do not want to cut away the bubbles, this will cause a larger hole.
Load the syringe with a silicone-based sealant..
Inject the sealant into the bubble.
Massage the bubble flat. Place plastic wrap or wax paper over it.
Put a weight on the area and let it dry for one day.
