Flat and low-slope roofs in Jacumba run about $11 to $18 per square foot installed, TPO at the top for its heat reflectance and lifespan, modified bitumen and built-up lower. A 1,200 square foot low-slope section lands roughly $14,000 to $22,000 depending on membrane, insulation, and how many penetrations need flashing.

If the existing membrane is sound and dry underneath, a silicone or acrylic restoration coating at $3 to $7 per square foot can add years for a fraction of a tear-off. If the insulation is wet or the seams are failing, coating just traps the problem, the matched roofer moisture-tests before recommending it.
