Flat & Low-Slope Roofing
in Charlotte, NC

Flat Roofing That Actually Stays Dry

Flat and low-slope roofs present unique challenges that most residential roofers are not equipped to handle. Water does not run off a flat roof the way it runs off a pitched one. It pools. It sits. It finds every seam, every penetration, every weakness in the membrane — and it exploits them relentlessly. Installing a flat roof correctly requires specialized knowledge, specific materials, and meticulous attention to detail at every seam, flashing point, and drain location.

Charlotte Roof Master has installed and repaired flat roofing systems on hundreds of commercial buildings, multi-family residences, home additions, garages, carports, and covered patios across the Charlotte area. We use only commercial-grade membrane systems designed for the long haul — not the cheap rolled roofing that home improvement stores sell to weekend warriors.

Flat Roofing Systems We Install

• TPO (Thermoplastic Polyolefin) — The most popular commercial membrane. Heat-welded seams create a monolithic waterproof surface. Highly reflective white surface reduces cooling costs by up to 30%. 15-30 year warranty depending on thickness. Excellent resistance to UV, ozone, and chemical exposure. Our recommended system for most flat roof applications.
• EPDM (Rubber Roofing) — Proven synthetic rubber membrane with 50+ years of track record. Excellent flexibility in cold weather, superior puncture resistance, and long-term durability. Available in black (standard) or white (reflective). Ideal for large, uninterrupted roof surfaces.
• Modified Bitumen — Asphalt-based membrane reinforced with fiberglass or polyester. Installed in overlapping sheets with torch-applied, cold-adhesive, or self-adhering methods. Excellent for roofs with moderate foot traffic. Multi-layer systems provide redundant waterproofing.
• Spray Polyurethane Foam (SPF) — Seamless, self-flashing insulation and waterproofing in one application. Fills every crack and contour. Excellent for irregularly shaped roofs with many penetrations. R-value of 6.5 per inch provides superior insulation.

Flat Roof Drainage Design

The number one cause of flat roof failure is inadequate drainage. Standing water — known as ponding — accelerates membrane degradation, adds structural load, breeds algae and mosquitoes, and will eventually find its way inside. Every flat roof we install includes a comprehensive drainage plan with proper slope (minimum 1/4 inch per foot), strategically placed internal drains or scuppers, and overflow provisions. We do not install a membrane and hope for the best. We engineer the system to move water off your roof quickly and completely.
