A properly installed TPO roof typically lasts 15 to 30 years. Membrane thickness is the biggest variable — 45-mil membranes generally perform toward the lower end of that range, while 60-mil and 80-mil systems installed on well-maintained substrates consistently reach 25–30 years in Louisiana's climate. Annual inspections and prompt attention to minor repairs are the most reliable way to extend service life toward the upper end of that range.

TPO is a white, reflective thermoplastic membrane with heat-welded seams. EPDM is a black thermoset rubber membrane seamed with adhesive or tape. The core difference that matters in Louisiana's climate is energy performance — TPO's reflective surface can reduce rooftop surface temperatures by up to 50–80°F compared to dark membranes like EPDM, which translates directly into lower cooling costs during hot summers. Heat-welded TPO seams also tend to outperform adhesive EPDM seams under the thermal expansion and contraction that Louisiana's seasonal temperature swings create.

They're different tools for different jobs — and we install both. TPO is a single-ply thermoplastic membrane best suited for flat and low-slope roofs where energy efficiency and installation speed are priorities. Modified bitumen is a multi-layer asphalt-based system that provides excellent redundancy through its layered construction and handles heavy foot traffic better than TPO. We'll tell you which one makes more sense for your building after a free inspection.

Installed TPO roofing in the Shreveport market typically ranges from $5 to $10 per square foot depending on membrane thickness, attachment method, roof accessibility, existing substrate condition, and whether tear-off is required. Larger commercial and multifamily projects often come in at the lower end of that range per square foot due to economies of scale. We provide free written estimates after an on-site inspection — contact us to schedule yours.

In some cases, yes. A TPO recover can be installed over an existing membrane if the substrate is structurally sound, moisture-free, and local building codes permit it. Most jurisdictions allow up to two roofing layers before a full tear-off is required. A recover can reduce labor and disposal costs significantly, but it's only the right call when the existing substrate is in solid condition. We'll assess your roof during the free inspection and advise honestly on whether a recover or full replacement gives you better long-term value.

Yes. Hodge Roofing provides a 2-year labor warranty on all full TPO installations. Manufacturer material warranties are available depending on the TPO system selected — coverage terms and conditions vary by manufacturer and system. Extended warranties covering both labor and materials are available on qualifying projects. We'll walk you through warranty options during the scoping process so you know exactly what coverage you're getting before work begins.

The clearest signs that your TPO roof needs professional attention are visible membrane shrinkage pulling away from flashings, seam separations, blistering or bubbling in the membrane surface, water that pools and doesn't drain within 48 hours after rainfall, or active interior leaks. A TPO roof that shows isolated damage in one or two areas is often a strong repair candidate. A roof with widespread seam failures, significant shrinkage, or a substrate compromised by long-term moisture intrusion typically warrants full replacement. We offer free inspections to make that call honestly.

Yes — it's one of the strongest arguments for TPO in Louisiana's climate. TPO's white reflective surface meets ENERGY STAR reflectivity standards and can reduce rooftop surface temperatures by up to 50–80°F compared to dark membranes. For a commercial building or apartment complex running HVAC heavily through a Louisiana summer, that surface temperature reduction translates directly into lower cooling loads and reduced energy costs. It also reduces thermal stress on the membrane itself, which contributes to longer service life.
