PVC Roofing Savannah GA Chemical & Grease-Resistant Commercial Membrane Systems
PVC single-ply roofing built for Savannah's restaurants, cold storage, food-service plants, and chemical-exposure rooftops where TPO won't hold up. Heat-welded seams. 20-30 year warranties. Installed by the locally-owned Savannah commercial roofing crew who already maintains it under CoastalCare™.
Why PVC Roofing Is the Right Membrane for Savannah Commercial Buildings
PVC (polyvinyl chloride) is the single-ply membrane the rest of the industry quietly defaults to when a building has chemical exposure, grease venting, animal fats, or restaurant kitchen exhaust on the roof. Coastal Georgia's restaurant density, cold-storage and seafood-processing footprint, hospital and lab buildings, and tourism kitchens all sit squarely in that category. TPO is cheaper up front. PVC lasts on a rooftop that TPO would have to be patched on within five years.
A PVC membrane is reinforced with a polyester or fiberglass scrim, then heat-welded at every seam during install. The welded seam becomes one continuous piece of plastic — there is no glue, no tape, and no overlap dependent on adhesive aging. Properly installed PVC roofs in Savannah routinely run 25-30 years before reroof, with manufacturer warranties available up to 30 years on commercial assemblies.
Coastal Roofing of Georgia is a locally-owned Savannah commercial roofing contractor. We install PVC systems for restaurants, hospitals, cold-storage facilities, hotels, schools, and industrial buildings across Chatham, Bryan, Liberty, and Effingham counties. Our crews are based in Richmond Hill — not Atlanta, not a regional rollup's satellite office.
When PVC Wins Over TPO — and When It Doesn't
PVC and TPO look almost identical on the rooftop. The difference shows up at year five and year fifteen, and it shows up under specific exposure conditions. Here's when each wins:
Choose PVC when…
- • The building has kitchen exhaust, fryer venting, or grease discharge on the roof
- • The property is a restaurant, food-service plant, or cold-storage facility
- • There is chemical exposure (labs, hospitals, manufacturing, marine)
- • You want a 25-30 year service life and a 30-year warranty option
- • The roof has animal fat, oils, or petrochemical exposure
- • Owner wants the longest-life single-ply membrane available
Choose TPO when…
- • The roof is a clean warehouse, retail, office, or church without chemical exposure
- • Budget is the deciding factor and the projected service life is 15-20 years
- • The owner wants the lowest material cost commercial single-ply
- • Building has no grease, no chemicals, no animal fats on the roof
- • A 15-20 year warranty meets the asset-hold horizon

Savannah Building Types We Recommend PVC For
Restaurants & Commercial Kitchens
Savannah's downtown and Pooler restaurant corridor put grease, animal fats, and frying oils directly onto rooftops via exhaust vents and hood discharge. PVC is chemically resistant to all of them. TPO is not — grease softens TPO and degrades the seam adhesion. For a 20+ year tourism-economy restaurant roof, PVC is the right call.
Cold Storage & Seafood Processing
Refrigeration condensate, ammonia, and salt-air exposure are routine on Coastal Georgia's cold-storage and seafood-processing buildings. PVC handles all three. We install PVC over rigid polyiso insulation with thermal-barrier sequencing that meets FM Global standards for refrigeration buildings.
Hospitals, Labs & Healthcare Facilities
Hospital and lab rooftops vent chemicals, sterilizers, and lab-exhaust fume hoods. PVC is the single-ply membrane the design-engineering community defaults to for healthcare. Pairs with our hospital roofing minimal-disruption work plan and Joint Commission-ready documentation.
Hotels, Tourism & Hospitality
Downtown Savannah hotels and River Street hospitality buildings combine rooftop kitchen exhaust, salt-air corrosion, and the financial reality that a roof failure during peak tourism season is catastrophically expensive. PVC's 25-30 year service life and grease-resistance make it the conservative engineering choice.
Schools & Institutional Buildings
School cafeteria kitchen exhaust + 30-year asset hold + budget-conscious lifecycle planning = PVC. Many Savannah-Chatham County and surrounding district schools spec PVC for cafeteria and kitchen blocks specifically. See our school roofing program for K-12 and private school work.
Manufacturing & Industrial Plants
Coastal Georgia's industrial corridor — Pooler logistics parks, the Savannah ports footprint, and Brunswick's industrial properties — frequently has chemical exposure and FM Global rating requirements that drive PVC specs. We work to FM Global 1-90, 1-60, and 1-75 wind-uplift ratings depending on geographic zone.
Our PVC Installation Process in Savannah
1. Roof Assessment & Substrate Survey
We start with a thermal-imaging assessment of the existing roof to identify wet insulation, hidden saturation, deck issues, and uplift risks. We document everything in writing before any teardown begins — saves change-order surprises.
2. Tear-Off, Deck Repair & Insulation
Where appropriate we tear off to the deck, repair any structural deck damage, and install rigid polyiso insulation to current code R-value (Climate Zone 3A for Savannah). Cover board over the iso. Crews are OSHA 30 and fall-protection trained.
3. PVC Membrane Layout & Mechanical Attachment
The PVC membrane is rolled out, plated, and mechanically attached (or fully-adhered, depending on deck and design wind speed). We work to the manufacturer's wind-uplift pattern, not eyeballed spacing. Documented per fastener pattern in the warranty package.
4. Heat-Welded Seams & Detail Work
Every seam is heat-welded with a robotic welder at the manufacturer-specified temperature and speed. Penetrations, parapet walls, and curbs are detailed with prefabricated PVC pipe boots and target patches. Probe-tested for cold-weld defects.
5. Manufacturer Inspection & Warranty Issuance
A manufacturer field-technician inspects the completed install before sign-off. Once approved, the 20, 25, or 30-year manufacturer warranty is issued — covering both labor and materials per the spec sheet.
6. Onboarded to CoastalCare™
The new PVC roof is added to our CoastalCare™ commercial roof maintenance program for semi-annual inspections, photo documentation, and minor repair credits. Preserved warranty, longer service life.
PVC Roofing Cost Ranges & Warranty Options in Savannah
PVC is typically 15-25% more expensive than TPO up-front, but lower lifecycle cost when the building has chemical, grease, or fat exposure. Real 2026 Savannah-area ranges for commercial PVC work:
| Project Scope | Typical Range |
|---|---|
| PVC patch / small repair (under 200 sq ft) | $800 - $3,500 |
| PVC re-cover (over existing approved substrate) | $8 - $14 / sq ft installed |
| PVC full tear-off + reinstall (typical commercial) | $10 - $18 / sq ft installed |
| PVC for restaurant / grease-exposure rooftop | $12 - $20 / sq ft installed |
| PVC for cold-storage / FM Global rated assembly | $14 - $24 / sq ft installed |
Available warranty terms (depending on system + assembly + manufacturer):
- • 20-year standard: material + labor, single-source manufacturer-issued
- • 25-year extended: includes wind-uplift coverage and is the most common spec for hospital / cold storage / school work
- • 30-year premium: available with thicker-mil membranes (typically 80-mil PVC) and FM Global-rated assemblies

Common Questions About PVC Commercial Roofing in Savannah
How long does a PVC commercial roof last in Savannah, GA?
A properly installed PVC commercial roof in Savannah typically lasts 25-30 years before requiring replacement, with manufacturer warranties available up to 30 years on premium 80-mil membranes. Heat-welded seams, UV stability of the PVC formulation, and Coastal Georgia's relatively mild winters all extend membrane life compared to inland-South commercial roofs.
Is PVC roofing better than TPO for Coastal Georgia?
PVC is better than TPO for any commercial building in Coastal Georgia that has restaurant kitchen exhaust, grease venting, animal fats, chemical exposure, or refrigeration condensate on the roof. For clean warehouses, retail boxes, churches, and offices without that exposure, TPO is the more cost-effective single-ply at a 15-20 year service life. See our PVC vs TPO guide for the full decision framework.
What does a PVC roof cost per square foot installed in Savannah?
PVC commercial roofing in Savannah typically runs $10-$18 per square foot installed for standard commercial assemblies, $12-$20 per square foot for restaurant grease-exposure rooftops, and $14-$24 per square foot for cold-storage or FM Global-rated assemblies. Tear-off versus re-cover, deck condition, insulation R-value, and warranty term all move the number.
Can PVC be installed over an existing TPO or built-up roof?
Sometimes — depends on the substrate condition. If the existing membrane is intact, dry, and structurally sound, a re-cover assembly is often viable and saves the cost of tear-off and disposal. We do a thermal-imaging assessment first to confirm there is no hidden wet insulation or deck damage. Where saturation or deck damage exists, full tear-off is required to honor manufacturer warranty.
Does PVC roofing qualify for cool roof / Energy Star credits?
Yes — white PVC membranes have high solar reflectance (typically 0.80+ initial reflectance) and meet Energy Star and CRRC cool-roof rating thresholds. In Savannah's climate that translates into measurable cooling-load savings on conditioned spaces. See our cool roofing Savannah GA page for utility rebate and energy-savings detail.
Do you handle PVC roof repair as well as new installs?
Yes. We patch, repair seam separation, replace pipe boots, and repair puncture damage on existing PVC roofs across Savannah and Coastal Georgia. Many of our PVC repair calls come through the CoastalCare™ maintenance program, where the issue is caught at a semi-annual inspection before it becomes a leak.
