   I have a roof with a 1 in 12 (seven degree) pitch. The house has cathedral ceilings (plastered) with about 8 inches of fiberglass insulation between the rafters. I am located in Eastern Massachusetts and the house was built in 1958. I have lived here with my family for 20 years.
   The house has a heavy grade of shingle and when we put a new roof on about 7 years ago we had ice and moisture barrier put over the entire roof. This worked reasonably well for about 5 years but now when we have a build up of snow or ice, or a heavily blown rain, leaks are developing. I know that I have found the offending nail when I pull it and find it rusty over its entire length. It appears that as the nails have worked up and down with temperature changes the ice and moisture barrier is losing its seal.

   The only solution, I am sure,is a new roof. I believe that there are just a few options available to me, rubber (black), a single ply material made by Duo Last (white, black or tan) or possibly standing seam metal roofing. Parts of the roof are visible from the ground and I like the tan color.

   The Duo-Last product is classified as a Co-polymer alloy consisting of resins and plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. The quote we received so far for this roofing are also less expensive than the rubber roof quote that we received. Both quotes included removing the shingles and putting an insulating board over the existing ice and moisture barrier material.

   Comments on any roofing options for a low slope roof in a residential application would be greatly appreciated.

   *Rubber is good. Two-ply torch-on modified bitumen comes in colours and is nearly as good as long as the edge detail is done well.

   *Ron,Many thanks for your response. The "Duro Last" material we have looked at is single ply modified Bitumen. Are you familiar with it? The colors offered are black, white and tan, and the tan would be acceptable to us.The contractors we have talked to about "rubber roofing" have told us that it only comes in black and white and they advise against the white because it quickly looks dirty in our climate and they claim it costs twice as much. It sounds like you are familiar with manufacturers offering colored materials. Do you have any names of manufacturers that we could contact? Again, thanks for your help.Regards,Al Amos

   *You're welcome.Soprema mod-bit roofing is available nearly everywhere. http://www.sopremaworld.com/Monsey Bakor, a US company, is available in most of North America.http://www.monsey-bakor.com/Their product lines are available in quite a few different colours and I think they both have a self-adhesive line. Most of my roofing is done with IKO products. I'm not a full-time roofer, though. Check the yellow pages. Talk to a roofer. I hear there are honest ones. I'd go with 2-ply instead of a single layer. And do the details the way the manufacturer says to.

   *Use a reputable roofer, who has insurance and previous experience. This material is like welding steel. it looks easy but it is more difficult than it appears. 2 ply mod bit makes a very durable roof Mike Galt, Ontario, Canada

   *Good joke. It rings true, too. The MG I was asking about is well known in the canoe world mainly for what is called "canoe dance". I've just told you all I know about it.
