   One thing to keep in mind is that, without special treatment, shingles should not be used on a slope any flatter than 3-4 inches in a foot.

   Thanks. We recently married and I have moved in to find this really nice workshop area with a bad roof at the rear. I'd like to salvage the building. ANy thoughts as to what to use? I'm stuck with the slope of 1:12. I realize that the rise/run is suboptimal. Could I use aluminum? A product that Lowes sells called Ondura? Thanks

   Here is a sketch of the problem. The shed is 8 feet at the rear and 10'8" at the front.

   With that slope probably your best bet (zero leaks if properly applied) is a rubber membrane. Cheapest (but also least durable) would be roll roofing with liberal use of mastic. Metal roofing would be more durable and more attractive, but depending on the style (and your weather) you could have some problems with the laps sealing.

   From what I've read on this forum from others, Ondura is not a good product--easily damaged, etc.. The slope is too shallow for shingles, so metal or roll roofing may be your best bet. Some people here have used EPDM on flat roofs, maybe that would work, but I'm not sue how expensive it is. I just saw an ad in The Journal of Light Construction for a product that is self-adhering like water and ice shield but intended for the whole roof. It's called "Peel & Seal;" they have a a toll-free number 800-882-ROOF, or you can go to http://www.mfmbp.com .

   There are apparently other similar products--there was discussion about this just the other day her at Breaktime. Forgot the title of the thread, but it should still be here--something like "self-stick roofing." If you can't find it, you can click on the "advanced search" function at the top of the column that lists all the discussions, type in the words like "self stick roofing" and when it asks for a time frame choose something like "within the past week" and it should give you the discussion.

   Edit: Discussion title is "peel-and-stick roofing: any good?" and is number 95416.

   Ondura is the biggest waste of money you could make so that is out

   The pitch is too low for shingles so that is out

   You want economy job so the EPDM is out

   Which leaves you with metal and caulked laps, or roll roofing

   Aluminum roofing is among the premium choices for metal roofing, just like its more expensive cousins, copper and zinc. That's partly because it offers superior corrosion resistance to regular ferrous (steel) roofing options. This characteristic makes it a frequent choice in coastal environments.
