GOLIATH ROOFING
Commercial-grade flat roofing for businesses and modern homes. White TPO reflects 90%+ solar radiation for maximum energy savings.
Modern flat roofing systems deliver energy efficiency, design flexibility, and reliable performance in Florida's heat and rain.
White TPO and PVC membranes reflect over 90% of solar radiation, slashing cooling costs in South Florida's year-round heat.
Warehouses, offices, retail, modern homes, patio covers, and carports. The versatile choice for any flat structure.
No Dollar Limit warranties available for commercial projects. Full coverage for materials and labor with no depreciation.
Properly installed and maintained flat roofing systems deliver 20-30 years of reliable, leak-free service.
Single-ply white membrane, heat-welded seams
The industry standard for flat roofing in South Florida. White TPO reflects over 90% of solar radiation, dramatically reducing cooling costs. Heat-welded seams create a monolithic, watertight barrier that outperforms mechanically fastened systems. Available in 45, 60, and 80 mil thicknesses.
Multi-layer rolled membrane, torch or peel-and-stick
Time-tested multi-layer system with excellent puncture resistance. SBS-modified bitumen stays flexible in Florida heat. Can be surfaced with reflective coatings or granules. The most forgiving system for rooftop traffic from HVAC equipment access. Best for residential flat sections and additions.
Multiple alternating layers of bitumen and reinforcing fabric
The original flat roofing system with a proven track record spanning 100+ years. Multiple layers create redundant waterproofing. Gravel surfacing provides UV protection and fire resistance. Heaviest option, best for large commercial structures with strong decks.
Single-ply synthetic rubber membrane
Extremely durable synthetic rubber membrane with excellent weathering characteristics. Available in black or white. Lower cost than TPO but requires adhesive or mechanically fastened seams rather than heat-welded. Works well for smaller flat roof areas and patio covers.
Single-ply reinforced membrane, heat-welded seams
Premium single-ply with superior chemical resistance. Ideal for restaurants, commercial kitchens, and properties near grease exhaust. Heat-welded seams like TPO. Slightly more expensive but better resistance to ponding water, chemicals, and fire.

Drainage design and material selection are critical in a state that averages 60 inches of rain per year.
Florida's intense summer rain events dump 3-5 inches per hour. We engineer every flat roof with proper slope (minimum 1/4 inch per foot), oversized drains, overflow scuppers, and tapered insulation systems to prevent ponding. Drainage is not an afterthought; it is the design.
Flat roofs are the standard for Miami Beach, South Beach, and contemporary builds throughout South Florida. Modern residential design increasingly features flat roof sections combined with butterfly or mono-slope profiles for a clean, architectural look.
For commercial projects, we offer No Dollar Limit (NDL) warranties from manufacturers including GAF, Carlisle, and Firestone. NDL warranties cover 100% of repair or replacement costs with no depreciation for the warranty period. The gold standard for property managers and building owners.
Beyond standard buildings, flat roofing systems cover patio covers, carports, pool enclosure roofs, equipment platforms, and elevated walkways. We install flat systems on any structure where a low-slope solution is needed.
