Have a house in Tucson with a flat roof. Has some ponding, but the Sun out
here would dry a lake. Had some roofers look at it and now have conflicting
suggestions. Roofer 1 says a fabric roof is best, roofer 2 says a built up
roof with three layers of fiberglass and hot tar is best.

My question should be, what is the best roof system for a flat roof in
Southern Arizona?

What really surprises me is their quotes. They are about $50 apart?? $7,500
for 3,500 sq. ft. +, +, + for any hidden stuff.
