How much does TPO roof repair cost in Myrtle Beach?

Single-point TPO repairs on Grand Strand commercial buildings run $275-$1,800 in our typical scope. A puncture patch with hot-air weld is $275-$850. A failed seam runs $350-$1,200. HVAC curb flashings run $650-$2,400. Hurricane edge metal repairs run $1,200-$6,500 per perimeter run. Multi-point repair scopes (3+ locations on one visit) usually run $1,800-$4,500 total because mobilization, infrared scan, and probe-testing are shared overhead. Emergency tarp service runs $385-$650 for the initial dispatch. All ranges assume one mobilization to the site, certified-installer labor, manufacturer-matched TPO stock, stainless fasteners on coastal exposures within 2 miles of the Atlantic, and probe-tested seams. We give a written scope with line-item pricing before any work starts — no on-roof surprises.

Can a TPO roof be patched, or does it need full replacement?

Yes, TPO roofs are highly repairable when the membrane itself is structurally sound. The decision rule we use: if the membrane is under 70% of its rated lifespan and the damage is localized (seams, punctures, HVAC curbs, edge metal, pipe boots), repair is the right answer. If the membrane is past 80% of its rated lifespan, has widespread blistering or de-lamination, or has multiple wet-insulation zones detected on an infrared scan, replacement is the right answer. The honest math: a $1,500 repair on a 22-year-old membrane that has 2-3 years of life left is wasted money. A $1,500 repair on a 12-year-old membrane that has 10-13 years of life left is excellent value. We give you the age math up front — we'd rather not sell you a repair you shouldn't buy.

How do you find the actual leak source on a TPO roof?

Three-step process. First, walk the membrane and inspect every seam, penetration, edge detail, HVAC curb, and visible failure point. About 60-70% of Grand Strand TPO leaks are visible on a careful walk. Second, on the 30-40% where the visible signs don't match the interior leak location, we run a commercial-grade infrared moisture scan during late-afternoon thermal differential (typically 4-7 PM when the roof has stored heat and wet insulation reads cooler than dry). The infrared scan maps every wet zone in the substrate, which is rarely directly under the visible interior leak — water travels along seams and substrate boards before it drops through the deck. Third, we do an electronic leak detection (ELD) low-voltage probe scan on the membrane surface if the moisture pattern doesn't have a visible cause. ELD will find pinholes invisible to the naked eye. We use whichever combination is appropriate for the leak profile — and always tell you why.

How long does TPO roof repair take?

Same-day for a single-point repair (one seam, one puncture, one boot). 1-2 day scope for multi-point repairs (3-6 locations). 3-5 days for HVAC-curb-heavy scopes that require metal fabrication and counterflashing. Emergency tarp service is dispatched within 2-4 hours for active leaks in the Myrtle Beach/Conway/Surfside/North Myrtle service radius. Hurricane edge metal repairs run 2-4 days because the metal work, membrane work, and edge sealing all have to dry before the next layer is installed. We schedule occupied buildings (hotels, restaurants, retail) around low-traffic windows to minimize guest or customer impact, and we send a project manager to every active job daily so the owner gets a written progress note every evening.

Will saltwater and hurricane wind affect my TPO repair?

TPO membrane itself is salt-air stable — the polymer chemistry doesn't degrade in coastal exposure. What gets attacked is every piece of metal in the roof system: fasteners, termination bars, edge metal, counterflashings, coping, pipe flashings, HVAC curb seals. Standard galvanized steel corrodes 3-5x faster within 2 miles of the Atlantic vs inland. For any Grand Strand commercial TPO repair on the ocean side of Highway 17, we upgrade to stainless-steel fasteners, heavy-gauge galvanized or stainless edge metal, and marine-grade coping on every repair we touch — even when the original install used standard galvanized. The 3-5% material premium doubles the lifespan of those components. On hurricane wind: every perimeter repair gets FM-approved hemmed edge metal with hurricane cleats, because edge-metal failure is the #1 hurricane-related commercial roof failure mode on the Grand Strand, not membrane failure.

Do you offer 24/7 emergency TPO repair in Myrtle Beach?

Yes — 24/7 emergency dispatch on the Grand Strand at (843) 877-5539. Active commercial leak calls (hotel, condo, restaurant, retail, industrial) get priority routing. Typical response time is 2-4 hours during business hours, 4-6 hours overnight or weekend. Initial dispatch includes infrared moisture mapping when conditions allow, emergency tarp installation if the roof is safely accessible, photo documentation for insurance, and a written scope of the permanent repair sent the next business morning. We carry TPO stock in 60-mil and 80-mil, both white and tan, in the most common manufacturer formulations (GAF EverGuard, Carlisle Sure-Weld, Firestone UltraPly, Johns Manville) so we can make a manufacturer-matched repair on the same dispatch in most cases.

Can you repair a TPO roof if I don't know who installed it originally?

Yes. About 40-50% of our Grand Strand commercial repair calls are on TPO roofs where the original installer is gone, unknown, or not returning calls. We identify the membrane manufacturer and mil thickness on the first site visit through visible markings, sample-cut analysis, or weld-pattern signature. We then source manufacturer-matched repair stock and execute the repair using that manufacturer's heat-weld specs. If the existing membrane is past warranty (typical for 15+ year-old roofs), we cannot extend or transfer the original manufacturer warranty — but our own workmanship warranty on the repair scope is 1-5 years depending on the failure mode and how much of the surrounding membrane we touched. The repair documentation we deliver is enough to satisfy most commercial insurance carriers for ongoing coverage purposes.

Should I try a TPO repair kit from Home Depot first?

Honest answer: no, not on a commercial Grand Strand building. Peel-and-stick TPO patches and over-the-counter sealants work on RV roofs, sheds, and DIY-scale residential flat decks. On a commercial roof exposed to hurricane wind load, salt-air UV, and 12-month thermal cycling, a peel-and-stick patch will fail within 30-90 days — and the failure often happens at the worst possible time (during a storm event, when wind catches the patch edge). Liquid sealants cover the symptom for a few weeks but don't address the structural cause of the leak. The only legitimate DIY emergency use case for a commercial building is a 24-48 hour stop-gap to control active interior damage before a heat-welded permanent repair. Even then, photograph the temporary patch carefully so your insurance carrier has documentation that you took reasonable steps to mitigate the leak.

What's the warranty on a Weather Shield TPO repair?

Our workmanship warranty on a single-point TPO repair is 1 year on small patches and seam repairs, 3 years on full HVAC curb rebuilds and pipe boot replacements, and 5 years on hurricane edge metal rebuilds where we install fresh FM-approved metal. The warranty covers our weld integrity and the metal-flashing work — it does not cover damage to the rest of the membrane from causes outside the repair scope (storm damage, foot-traffic punctures elsewhere, third-party HVAC work). On larger-scope repairs (full-coating extension, partial re-roof, large infill patches), we work with the manufacturer (GAF, Carlisle, Firestone, JM) to extend their material warranty to the repaired zone wherever the existing roof is within warranty age. We document the warranty terms in writing on every job — no verbal-only promises.

Why should I use Weather Shield instead of a national TPO repair service?

Three reasons. First, we live here. Hurricane response time matters when your building has an active leak and the storm has just rolled through — we're on the Grand Strand and can dispatch in hours, not days. Second, we know the specific coastal SC failure modes — salt-air fastener corrosion patterns, ocean-vs-inland material specs, hurricane edge-metal requirements that national providers learn after the fact. Third, accountability is local. If something goes wrong on a repair, we're driving back to the same building tomorrow — not filing a callback through a regional dispatch center two states away. National providers have a place on very large multi-property portfolio contracts. For a single Grand Strand commercial building, a local certified contractor is the better choice in 90% of repair scenarios.
