How much does a flat roof cost per square foot in Rancho Santa Fe?
Flat and low-slope roofs in Rancho Santa Fe 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.
Can a flat roof be coated instead of replaced?
