TPO Roofing Cost in Myrtle Beach: 2026 Commercial Price Guide
TPO roofing in Myrtle Beach typically costs $6.50-$13.50 per square foot installed for commercial flat and low-slope roofs. The final number depends on roof size, membrane thickness, insulation, tear-off, ponding water, HVAC curbs, wind exposure, and whether the building is a hotel, condo, restaurant, retail center, or warehouse.
Important pricing note: the numbers on this page are educational planning ranges for Myrtle Beach and Grand Strand commercial roofs. They are not hard quotes, bids, or warranty promises. A real TPO price requires roof access, moisture checks, deck review, drainage review, and a written scope.
If you only need a localized leak fixed, replacement may be more than you need. See our TPO roof repair Myrtle Beach guide for seam, puncture, HVAC curb, ponding water, and emergency repair ranges. This page is for owners and property managers trying to budget a full TPO roof installation or replacement.
The Direct Answer: TPO Roofing Cost Per Square Foot
For a normal Myrtle Beach commercial TPO roof, use $6.50-$13.50 per square foot as the planning range. A clean, open, easy-access roof with dry insulation and a simple perimeter can land near the lower end. A roof with tear-off, wet insulation, ponding water correction, lots of HVAC equipment, or ocean-front wind exposure moves toward the upper end.
| TPO Scope | Planning Range | Typical Use Case |
|---|---|---|
| Basic recover over sound roof | $6.50-$9.50/sqft | Dry existing roof, code-compliant layers, simple roof field |
| Standard TPO replacement | $8.00-$12.00/sqft | Tear-off, new insulation, 60-mil TPO, normal curbs and drains |
| Coastal/high-traffic upgrade | $10.00-$13.50/sqft | 80-mil TPO, stronger edge metal, added walkway pads, more flashing |
| Complex hotel, condo, or drainage rebuild | $13.50+/sqft | Phased occupied work, saturated insulation, ponding water, many penetrations |
TPO Roofing Cost by Roof Size
Size matters, but it does not scale perfectly. Smaller roofs often look expensive per square foot because mobilization, dumpster, safety setup, edge metal, and flashing are spread across fewer square feet. Larger roofs can get better production efficiency, but hotels, condos, and retail centers add scheduling and access complexity.
| Building Type | Roof Size | Planning Range | What Changes Cost |
|---|---|---|---|
| Small retail bay or office addition | 2,500 sqft | $16,250-$33,750 | Often driven by minimum mobilization, edge details, and HVAC curb count. |
| Restaurant, medical office, or small strip-center unit | 5,000 sqft | $32,500-$67,500 | Grease exposure, curb flashing, and tenant schedule can change the scope. |
| Highway 17 retail strip or HOA clubhouse | 10,000 sqft | $65,000-$135,000 | Drainage, tear-off, and insulation upgrades usually decide the final number. |
| Mid-size condo, warehouse, or multi-tenant commercial roof | 25,000 sqft | $162,500-$337,500 | Staging, access, wet insulation, and phasing become major cost drivers. |
| Hotel, resort, large condo, or big-box commercial roof | 50,000 sqft | $325,000-$675,000 | Occupied-building logistics, hurricane edge metal, and guest disruption planning matter. |
The Six Cost Drivers That Matter Most
Two TPO roofs with the same square footage can price very differently. The membrane is only one line item. Insulation, tear-off, ponding water, roof access, edge metal, and flashing details often decide whether a job is a simple install or a major commercial capital project.
Membrane Thickness
45 mil, 60 mil, or 80 mil
60-mil TPO is the standard commercial choice. 80-mil costs more but adds puncture resistance for hotels, condos, and roofs with frequent HVAC service traffic.
Insulation and R-Value
$1.50-$5.50+ per sqft influence
Code-required insulation, tapered insulation, and wet-insulation replacement can move a TPO project more than the membrane itself.
Tear-Off vs Recover
$1.50-$4.50+ per sqft influence
Recovering over a sound roof can reduce cost, but saturated insulation, two existing roof layers, or trapped moisture usually require tear-off.
Ponding Water Correction
$3,500-$25,000+ added by zone
Drain cleaning is minor. Tapered crickets, added drains, or rebuilding low spots can become a separate drainage scope before the new membrane goes down.
Coastal Edge Metal
$15-$45+ per linear foot influence
Myrtle Beach wind exposure makes perimeter details critical. Ocean-side buildings often need heavier edge metal, hurricane cleats, and corrosion-resistant fasteners.
HVAC Curbs and Penetrations
$350-$1,500+ per detail influence
Every curb, vent, pipe, scupper, and roof drain needs flashing. Roofs packed with units cost more than clean open roof fields.
Myrtle Beach Examples: Hotel, Condo, Retail, Restaurant, Warehouse
Building use changes the roof specification. A warehouse can sometimes use a straightforward mechanically attached 60-mil TPO system. A restaurant may need PVC around grease exhaust. A hotel may need phased work, extra walkway pads, heavier edge metal, and stronger documentation because guests are under the roof while the work happens.
Ocean-front hotel or resort
$9.50-$15.00+ per sqftHigh wind exposure, many HVAC curbs, occupied-building phasing, guest disruption control, and stronger perimeter metal.
Condo or HOA flat roof
$8.00-$14.00 per sqftBoard documentation, multiple unit interiors below, reserve-study timing, and drainage correction often drive decisions.
Retail strip center
$7.00-$12.50 per sqftLarge open roof fields help cost, but tenant HVAC traffic, signs, parapets, and grease exhaust can add complexity.
Restaurant or food service roof
$8.50-$15.00+ per sqftGrease exhaust can make PVC or a partial PVC zone smarter than standard TPO around kitchen equipment.
Warehouse or light industrial building
$6.50-$11.50 per sqftSimple geometry can keep cost lower, unless process vents, chemical exhaust, or shutdown scheduling complicate the roof.
TPO Membrane: 45 Mil vs 60 Mil vs 80 Mil
TPO membrane thickness affects material cost, puncture resistance, and how much abuse the roof can take from service traffic. Most commercial Myrtle Beach projects should start the conversation at 60 mil. The 80-mil upgrade is worth pricing when the roof has frequent HVAC traffic, tenant access, hotel maintenance routes, wind-blown debris exposure, or a long hold period.
The lowest membrane number is not always the lowest lifetime cost. If a cheaper membrane saves money today but punctures more easily around HVAC routes, the owner can give the savings back in service calls. On the other hand, a simple warehouse with limited roof traffic may not need the most expensive membrane package.
Tear-Off, Wet Insulation, and Ponding Water
The biggest surprise in TPO pricing is usually under the existing roof. If insulation is wet, it has to be addressed. Covering wet insulation traps moisture, lowers R-value, risks deck damage, and can shorten the life of the new roof system.
Ponding water is the second major surprise. Myrtle Beach roofs take heavy rain, and flat roofs must drain. If water sits after storms, the project may need tapered insulation, crickets, scupper work, drain work, or a partial deck correction. That adds cost, but skipping drainage correction can turn a new TPO roof into an early leak problem.
Repair vs replacement checkpoint: if the roof only has one failed seam, one puncture, one HVAC curb leak, or a small ponding zone, get a repair assessment before budgeting a full replacement. Start with the TPO repair cost breakdown and compare that to the replacement ranges above.
What a Responsible TPO Estimate Should Include
- Measured roof area and roof sections included in scope
- Existing roof condition, layer count, and tear-off plan
- Moisture findings or core-cut assumptions
- Membrane manufacturer, color, and thickness
- Insulation type, R-value plan, and tapered drainage details
- Edge metal, scuppers, drains, curbs, pipes, and wall flashing
- Walkway pads for HVAC service routes where needed
- Occupied-building schedule, staging, and safety plan
- Clear exclusions, alternates, and change-order triggers
TPO Roofing Cost FAQs
How much does TPO roofing cost in Myrtle Beach in 2026?
Most Myrtle Beach TPO roofing projects fall between $6.50 and $13.50 per square foot installed. Simple open commercial roof fields can be near the lower end. Ocean-front hotels, condos, restaurants, roofs with saturated insulation, and roofs needing drainage correction can exceed the upper end. These are educational planning ranges, not a quote. A real price requires roof access, moisture checks, and a written scope.
Why is Myrtle Beach TPO roofing more expensive than inland work?
Coastal roof specs usually need stronger edge metal, corrosion-resistant fasteners, better attention to wind uplift, and more drainage planning. Salt air attacks metal components, hurricane wind stresses the perimeter, and heavy rain exposes ponding-water problems.
Is 60-mil or 80-mil TPO worth it?
60-mil TPO is the normal commercial standard. 80-mil TPO can be worth pricing on hotels, condos, retail centers, and roofs with heavy HVAC service traffic because it adds puncture resistance. The right choice depends on roof traffic, wind exposure, budget, and expected hold period.
Can TPO be installed over an existing flat roof?
Sometimes. A recover can reduce tear-off cost when the existing roof is dry, structurally sound, and within code layer limits. If the roof has wet insulation, trapped moisture, soft decking, or two existing roof layers, tear-off is usually the responsible path.
What costs more: TPO replacement or TPO repair?
Repair is cheaper when the damage is isolated. If you have a seam failure, puncture, curb leak, or small ponding zone, start with a repair assessment. If the membrane is near the end of its service life or moisture mapping shows broad wet insulation, replacement may be the better financial decision.
