Flat and low-slope roofs need a different system than pitched roofs. All Phase Construction USA installs and replaces single-ply and built-up flat roofs across Broward and Palm Beach County — on modern homes, additions, and commercial buildings — engineered for standing water, intense UV, and high winds.
For a typical residential flat section, single-ply runs about $4.00 to $10.00 per square foot installed ($8,000–$20,000 for a 2,000 sq ft roof), depending on membrane, insulation, and the number of penetrations and parapet walls. Most single-ply systems carry a 20–30 year service life.
Broward County is a legal High-Velocity Hurricane Zone, so flat roofs there use Miami-Dade NOA-approved assemblies with enhanced edge-metal detailing and fastening. Palm Beach County is not legally HVHZ, but we build to the county's wind code — and to HVHZ spec on request — with product-approved membranes on every job.
Call (754) 227-5605 for a free flat-roof inspection. We check the membrane, seams, flashings, and drainage, and give you a written repair-or-replace recommendation. Comparing membranes? See our single-ply roofing and infrared moisture inspection pages.
