A picture may help here, but I will try to explain my situation.
I have an old garage with a roof that slopes from front to back. The side walls just go straight up about 14 feet creating a garage that looks like it has fins. In other words its like a normal flat roof building, but there are walls at the edges. If you have seen one of these before you can probably picture it.
The slope of the roof is about a 12/2. I am going to use roll roofing because of a limited budget. What is the best way to deal with these sidewalls so they don't leak? I already have some #30 felt on the desk and going up the walls and overlapping the top plate. The problem is avoiding air space where the sidewall meets the roof deck. I am afraid this area will get holes poked in it easily. I was thinking about cutting the felt at this point and lapping ice guard down the walls out onto the deck a couple of feet. Then I would nail flashing on top of all this before installing the roll roofing.
In this situation I will have ice on top of felt. Is this a big problem? Has anybody else delt with this problem?
I will try to post a picture later.
