All right, I finally got time to get up on the roof. I took off all the trim, a vent, and pulled the rubber back about 4'. Luckily there is absolutely no signs of water intrusion and the rubber is still in great shape. So my plan is to buy some DAP WELDWOOD contact cement from Lowes and roll it on both the rubber and the wood, let it set, and roll the rubber back down. The only problem is the existing cement the factory used is still tacky. I am letting it air out in the hopes it will set up before tomorrow evening or Saturday morning. If not I guess I need to find something to clean it off with. Does anyone have any suggestions or experience with a certain type cleaner? Or should I not even worry about it and just go over it with the contact cement?
