flat roof carport

We are about to buy a house that has a flat roof carport. The roof seems to be leaking because the underside has a lot of black stains on it. The roof seems to be a rolled asphalt. What is the proper procedure to follow to replace this roof? Can a doityourselfer handle it? It's a small carport - just for one car.

Thanks for your help.

 

Install a metal roof on it. Asphalt and/or fiberglass roofing products and flat roofs just don't mix.

 

Lefty is correct. Install a metal roof. Good Luck

I have to disagree with Jack and lefty. If you want to save it and are willing to spend a little more money you could always have a 1 pitch roof installed so the water would run off instead of sitting on a flat surface.
If you go to install a metal roof or a wood framed roof make sure it's pitched and always get as many estimates as you can, but don't go with the cheapest est.
but the most experienced.

GOOD LUCK!

Gump, you have a point there, However, I have never seen anybody who knew what they were doing build a perfectly flat roof. What most folks call a flat roof, on a carport, shed, or whatever, in fact does have a slight slope to it. I assumed that the roof that JMB is talking about does have a slight slope. If it doesn't, then he needs to redo it in such a way that it does. If it falls 3 or 4 inches over a 20' span, that's plenty. But what he needs to get away from is the comp. roofing. 3-tab or architectural shingles work fine as long as the slope is at least 3/12. If the slope is less than that, then metal roofing, in my opinion, is the only vialbe alternative. The 90# rolled roofing that is presently there -- I, personally, wouldn't put that stuff on a dog house!
