I am trying to decide on different options for reroofing my 1800 sf flat
roof in Florida. Due to the past hurricanes the prices are high. The quotations run like this 1) $9000 to do a 2 ply fiberglass IV with a mineral surfased fib. cap sheet 2) 10,000. for a 2 ply fib. IV with a top of modified bitumen 3) $11,000. for 3 ply fib IV with gravel embeded in hot tar 4) $12,000. for 4 ply fib IV with gravel embeded
They all carry a guarantee of only 5 yrs.
I get confusing statements like:
a) mineral surface cap sheet will last 7 yrs or 15 yrs
b) modified bitumen top sheet, gets moldy due to water puddles
c) a 3 ply gravel roof will last 10 yrs or 15 yrs.
c) a 4 ply gravel roof will last 15 yrs to 20 yrs.
Aside from making the right choice I think the primary issue is to get
a good workmanship job done and I have no way of knowing who will do
an appropriate job. I’ve been unlucky in the past. Thats why I’m coming to you roofing psychiatrists. Help …Nat
