Flat roof options
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. Al |

Will the mosquitos be livestock or pets?

I also recommend the rubber roof, but no tires or flooding.

Your existing roofing system is likely to have insulation material embedded, followed by a top layer of sand cement screet and last but not least water proofing material such as a membrane. To redo the roof system, it is best to remove the existing system to ensure there is no overloading of the roof. In my experience with redoing my own flat roof several years back, I opted for removing the entire roofing system to the bare roof concrete. First layer was like a tar water proofing menbrane joined at the seams by some sort of flame heating guns. The second layer was 2" foam type insulation boards arranged like lap joints. The final layer was the sand cement screet done at a gradient for proper water drainage. It could be followed by another additional layer of water proofing membrane on top, but I did not take that option. I am still quite happy with it. |
