I am wondering if it would be possible to DIY install a metal roof on two sheets of torch down? I have read so far that this should often be possible. I live in the PNW, so lots of snow/ice is not expected.
I am wondering because my low-slope roof is not leaking, but there are areas where the sheets are a bit wavy. From the install instructions I have seen so far, I would be attaching the metal to pieces of wood that are fastened to the roof, so I don't think it would matter too much?
