Florida homes with flat or low-slope sections — additions, lanais, carports, mid-century designs — need a different system than the sloped roof they attach to.
TPO and PVC heat-welded single-ply, modified bitumen in torch, cold-adhered or self-adhered form, and silicone or acrylic coatings as a restoration over a sound substrate.
Ponding water is the number one cause of premature flat roof failure in Florida. If water is not clearing, correcting the drainage or adding tapered insulation matters more than the membrane choice.
Where a flat section meets a sloped roof is the most common leak point we find. That detail is worth more attention than the membrane brand.
