Roofing question?

Can water, if it stands long enough, seep through "roll roofing"? I assumed that it could not since it is seamless, but if it can,this will explain one of my roofing leaks.

1. i have a construction business, need an estimate email me..
2. is there any cracks in the roofing material or on the tar edges
3. Yes, it can...water is a universal solvent given enough time. It will percolate through solid granite over time so a thin layer of asphalt hasn't a chance if it just stands on it. Might want to build a grade of at least 1" rise per foot to solve that problem. Sorry.
4. Yes, if you look at the installation instructions on roll roofing you will see that is states that it is not for standing water applications. For that you need a torch down (modified rubber bitumen) roof or an EPDM roof (innertube rubber). The other option is to build a slope onto the roof.
5. It shouldnt seep threw but it all depends on how it was put on..if they used nails then yes it will leak... hubby ownes a roofing business 20 years experience..
6. depends on the pitch of your roof
