My NTM 8' 2007 Flagstaff PUP had ripples in the roof when I bought it. The roof itself is sound, with no apparent sagging or damage--although I'm prepared to address any damage I may reveal when the existing membrane is removed. I have done some research and would like recover the roof before my camping season begins. I'm confident that the remaining 2 ft of snow will be gone by April! I'm leaning toward EPDM, but I would appreciate feedback from others who have used this or other membranes. Questions: >I would use white EPDM. I've read about the black base discolouring or showing through. Has this been an issue in your application? >One video showed using a heat gun to remove the caulking, but did not recommend a temperature. Another website recommended 300F. Will this do the job? I can buy either a 300/500F or 750/1000F heat gun for under $30 CDN. >I'm looking for a source of roof membrane in a 12' length--preferably between Barrie and North Bay, Ontario. It seems that the shortest online lengths are 25'. All comments, advice and suggestions welcome!
