We have finially started removing the old rubber membrane off of the camper. We found this to be very difficult because the old membrane was in so bad of shape it tore apart when trying to pull off. Once we removed the membrane we noticed that a lot of the wood decking had rotted and had to be replaced. The support rafters were still ok. On this install instead of removing all of the rotted board we covered it with new one quarter inch thick plywood. then screwed it into the rafters. We then cut all of our vent holes and cut a hole for the air-c0nditionare. We now had our Rv roof ready to install. We opened our box that contained our Roof-Top EPDM rubber membrane and carried it onto the RV roof. We unfolded the rubber roofing and completly covered the wood deck. We had about ten inches extra hanging over the edge, this was ok since we will trim the excess after the rubber membrane is glued down. After the rubber roofing was in place we folded it back in half over itself. We did this length wise not width. Always be carfull when doing this and avoid falling into the holes you have cut into your roof deck for your vents and air-conditionare. Once the membrane was folded back over itself we applied the glue onto the wood deck and membrane. We let dry to touch and then laid the membrane into the glue. Once this is done repeat the proceedure. The easiest way we found to lay the rubber roofing onto the deck was to get two ladders and put them on opposite sides of the RV. Then have a person on each ladder. Each person would grab the rubber roofing and pull into the glue. Try to stay to geather while doing this to keep from getting wrinkles in the roofing. This install went smooth and we are now ready to install the metal end pieces and the metal around the roof. Will do this later.
