TPO Roofing Contractors in Coastal Georgia

Quality TPO roofing typically lasts 20-30 years with proper installation and maintenance. Lifespan depends on membrane thickness (45 mil vs. 60 mil vs. 80 mil), installation method, maintenance frequency, and environmental factors. Regular inspections and minor repairs can extend your TPO roof's life well beyond 25 years. Many manufacturers offer warranties ranging from 15-30 years depending on the system specification.

Both are white single-ply membranes, but TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) have different chemical compositions. TPO is generally less expensive, lighter weight, and performs well in most commercial applications. PVC offers superior chemical resistance (important near grease exhaust or chemical facilities), stronger seam strength, and typically longer warranties—but costs 20-40% more than TPO. For most Coastal Georgia commercial buildings, TPO provides excellent performance at a better value.

Yes, TPO is specifically designed for flat and low-slope commercial roofs. Its heat-welded seams create a completely waterproof barrier that prevents ponding water infiltration. TPO performs exceptionally well on roof slopes from completely flat (0°) up to 3:12 pitch. The reflective white surface is especially beneficial on flat roofs where heat absorption is a concern. TPO is used successfully on warehouses, retail centers, office buildings, and industrial facilities throughout Coastal Georgia.

TPO roofing costs typically range from $5-10 per square foot installed, depending on membrane thickness, insulation type, roof size, accessibility, and system complexity. Larger roofs (10,000+ sq ft) usually cost less per square foot than smaller installations. Thicker membranes (60 mil or 80 mil) cost more but last longer. Additional factors like removing old roofing, structural repairs, or complex flashing details affect total cost. We provide detailed written estimates after inspecting your specific facility and discussing your requirements.

Yes, in many cases TPO can be installed over existing roofing (called a "roof overlay" or "recover"). This saves on tear-off and disposal costs. However, the existing roof must be in good structural condition, relatively dry, and code-compliant for weight capacity. We assess your current roof during inspection to determine if an overlay is feasible or if complete tear-off is necessary. Some building codes limit the number of roof layers allowed, and heavily damaged or wet substrates require removal before new TPO installation.

TPO roofing requires minimal maintenance but shouldn't be neglected. We recommend biannual inspections (spring and fall), clearing debris from drains and scuppers, removing standing water or vegetation growth, and addressing minor issues before they escalate. Most TPO warranties require documented maintenance to remain valid. Professional inspections can catch small problems like loose seams, punctures, or fastener issues early—preventing expensive repairs or voiding your warranty. Regular maintenance typically extends TPO roof life by 5-10 years.
