Shingles on an almost flat roof? How almost flat? You do know you need
a certain amount of pitch for normal shingles, otherwise the water will
go "up". The way the shingles lay on each other reduces the effective
pitch of the roof. We had a leaky Florida room roof in my house in
Orlando -- it was an almost flat roof with asphalt shingles. BTW --
What's a roll shingle?
A drip edge sounds like a good idea to protect the plywood sheathing,
but I think the real weatherproofing comes from having the top row of
shingles go past the edge of the roof about an inch. If you're listing
the house for sale, why not ask whoever is going to certify the roof
what they'd like to see on there? Or do they not do roof certs there
yet?

Subject: How to shingle almost flat roof?
Greetings all,
Been lurking on the list for a few months and learned a great deal.
Finally have a question for you all.
I'll be putting a new roof on our Florida room this weekend and have not
been able to find any instructions on the net on how to deal with the
top edge of the roof. The room comes off the back of the house and,
when looking from the house, the roof pitches ever so slightly from
right to left. The highest point on the roof is on the roght hand side
and does not pitch back down or abutt a wall. The edge of the top
course of shingles is basically exposed. I have not been able to find
any information on the net explaining how to deal with this. I'd rather
not use the existing roof as a guide as it was poorly installed by the
guy we bought the house from and from dealing with his attempts at
wiring I think its safe to assume its wrong.
So how does the top edge get finished? I assume I would want a drip
edge there to keep rain from getting under the top course of shingles
(going to use 36" roll shingles). Would this go on top of the top
course? I would think so as that would be certian to keep rain from
getting under there. Nail every 5" or every 2'?
I would appreciate any input greatly. This is the last issue I have to
deal with prior to the house going on the market next week.
Thanks so much!
