DIY metal roof install

[Rich Riesmeyer]

Our rental has a covered deck on the back. Shingles, about 1 in 8 pitch. Of course, it leaks..... I thought a metal roof would be a permanent fix. Home Depot's site makes it seem like a straight forward install. One question I had was what keeps a metal roof from leaking at the screws? Can anyone recommend a better DIY guide to read?

I have a metal roof on my own home - I had a roofing guy do it. The type I have is called a "standing seam" & each course (containing screws) is covered by the lip of the next panel, so they're covered. The ends of the roof are wrapped in metal edging & then the panels overhang that slightly. You need to be ultra-careful with the flashing installation, as well. This is probably the most common type in these parts, although there are others. I will tell you that walking on those panels is like skating on a greased mirror - be extremely careful if you DIY!
