Low-slope roofs cover most of Central Florida’s retail, office, warehouse and multifamily common-area square footage. The system under that square footage decides how the building handles summer heat, afternoon downpours and hurricane wind. Here are the options and where each fits.
TPO (Thermoplastic Polyolefin)
The most common commercial membrane in the region. White, reflective, heat-welded seams, available in 45 to 80 mil. Good cost-to-performance, strong in heat, and widely supported by manufacturers. Best for warehouses, retail, offices and multifamily breezeways.
PVC
Similar to TPO in installation and appearance, higher cost, better resistance to grease, chemicals and standing water. The choice for restaurants, kitchens and buildings with rooftop exhaust. Compared in detail on the TPO vs PVC guide.
EPDM (Rubber)
A black synthetic rubber membrane with taped or glued seams. Durable and forgiving of movement, but black absorbs heat in Florida and seams need more maintenance than welded thermoplastic. Less common on new Central Florida commercial roofs; still found on older buildings.
Modified Bitumen
Asphalt-based rolls with polymer modifiers, applied in two or more plies by torch, cold adhesive or self-adhered. Handles foot traffic and rooftop equipment well, and granulated cap sheets come in reflective colors. Common on multifamily, schools and buildings with heavy HVAC service.
Built-Up Roofing (BUR)
Multiple plies of felt and asphalt with a gravel or cap-sheet surface. The traditional system; heavy, long-lived, and still specified on some institutional buildings. Repairs and recovers are common; new installs are less so.
Metal
Standing seam or screw-down metal works on low-slope roofs with at least minimal pitch. Long life, high wind ratings and low maintenance. Sunny Roofing fabricates panels and trim in house; see metal roofing.
Coatings
Silicone or acrylic coatings restore a sound existing roof at a fraction of replacement cost, add reflectivity and can carry a manufacturer warranty. They are not a fix for wet insulation or failed seams; a moisture survey decides whether a roof is a coating candidate.
Choosing
- Kitchen or chemical exposure: PVC
- Budget and broad manufacturer support: TPO
- Heavy rooftop traffic: modified bitumen
- Long life and wind: metal
- Sound roof, tight budget: coating

Frequently Asked Questions
Which commercial roof lasts longest in Florida?
Metal, followed by thicker PVC and TPO systems with good drainage and documented maintenance. Any system fails early with ponding water.
Can a flat roof be recovered instead of replaced?
Often, when there is one existing layer and the insulation is dry. A moisture survey and code review decide.
What does a maintenance program include?
Scheduled inspections, drain clearing, seam and flashing repairs and a written report each visit, which most manufacturer warranties require.
