The manufactured homes forum has few lurkers with actual experience. Most are just people with questions. Friend is considering buying a double-wide already sited on a lot. Thinks the lot itself is worth the price. The double-wide has shingle roof with just 2 - 12 pitch. My thinking has always been that about 3 1/2 - 12 is about the minimum for conventional shingles and that 4 1/2 - 12 or steeper is really better. So how do they get shingles to work on just 2 - 12 pitch?
