We are the commercial roof coating contractor for the Asheville market — silicone roof coating Asheville, roof restoration Asheville, and metal-roof restoration across Buncombe County, dispatched from our headquarters in Flat Rock, Henderson County about 25 minutes south. WNC is our home market, not a satellite. The restoration opportunity that most Buncombe County building owners overlook sits at year 15-20 of a commercial roof's life: instead of treating a tired roof as a binary tear-off-and-replace decision, a well-applied silicone or acrylic coating extends the existing roof's service life another 10-15 years at roughly 25-30% the cost of full replacement. The roof has to qualify — sound, dry, clean — but when it does, the math is hard to argue with.
The NPV case almost always favors coating on a qualifying roof. Take a 60,000 sqft TPO roof on a Fletcher or Arden light-industrial building installed around 2010 — now 15 years old and approaching end-of-warranty. Full tear-off and reroof in 2026 runs roughly $540K-780K at WNC commercial TPO replacement pricing. A silicone restoration on the same roof runs $165K-260K with a 15-year warranty extension. Deferring that $600K-plus capex from 2026 to 2041 — even net of replacement-cost inflation — produces meaningful NPV savings, and the roof keeps the building dry the whole time. The same logic applies harder to aging metal: full standing-seam replacement runs $14-22/sqft, so a $3/sqft coating defers an enormous capital line.
There's a tax-treatment dimension too. Full replacement is typically capitalized and depreciated over 27.5-39 years; a coating is frequently classifiable as a repair/maintenance expense deductible in the current tax year under IRC Section 162, with proper substantiation. For a C-corp at 21%, expensing a coating now versus depreciating a replacement over four decades can mean meaningful near-term tax savings on top of the deferred capex — confirm the characterization with your CPA, but the pattern holds for many WNC commercial owners and frequently tips the decision toward coating even before the cash-cost gap.
The constraint — and the reason we won't sell a coating on every roof — is substrate qualification. Coating works only on membrane that is structurally sound, dry, and clean. About 30% of the aging-roof surveys we run across WNC disqualify, and after Hurricane Helene (FEMA DR-4827) in September 2024 the share with trapped moisture rose: wind-driven rain saturated insulation on buildings across the Swannanoa corridor and beyond, and coating a wet substrate locks that moisture in and accelerates failure. We run an infrared thermal scan and moisture-probe cores before every Asheville coating bid. When we tell an owner the roof doesn't qualify, we mean it — the honest answer is a section replacement or full tear-off, and we'll scope that instead. For storm-driven moisture working through carriers, see our insurance-claim documentation and the NC commercial storm-event dataset.
Installed cost runs $2.50-5 per square foot across the Asheville market depending on substrate, required primer, and warranty tier — typically 25-30% of full-replacement cost. Ranges reflect Buncombe County bid data; mountain access on remote sites adds logistics cost.
Coating success is determined 70% by preparation and 30% by application. Our process follows NRCA and manufacturer-specific application standards from GAF, Gaco, and Henry, and starts with a thermal moisture survey on every roof — if the WNC substrate doesn't qualify, we say so before the bid rather than coat over a problem. The sequence below is what runs on a typical Buncombe County commercial roof, scheduled around the region's daily-thunderstorm cure window.
Licensed professional on-site within 48 hours of RFQ. Infrared thermal scan of the entire roof to detect trapped substrate moisture (wet insulation reads as a thermal anomaly versus dry substrate), plus core samples at 2 per 10,000 sqft confirming moisture content below 5%. Surface condition documented — granule loss, chalking, blistering, seam failures, penetration leaks. For Helene-zone buildings, water-intrusion history checked. If any section exceeds manufacturer moisture spec, we scope section replacement or tear-off for that area rather than coat it.
Power wash the entire roof at 2,500-3,500 psi to strip oxidation, dirt, algae, and biological growth — heavy on WNC roofs given the humidity and tree canopy. Anti-fungal treatment on mildew and mold areas. Detergent wash on greasy zones (brewery and food-processing exhaust, manufacturing smokestack drift). Rinse and allow 24 hours to dry completely before proceeding.
Tears, blisters, and mechanical damage patched with manufacturer-compatible material. Field seams inspected and re-welded or re-taped where failed. Metal-roof seams sealed with butyl tape plus elastomeric sealant. Penetration flashings re-flashed where needed; drains checked and cleared. Every repair must cure and bond before coating begins — this is where 70% of coating success is determined.
Substrate-specific primer where manufacturer spec requires it. Aged TPO with surface chalk almost always needs primer; sound EPDM often doesn't; oxidized galvanized metal needs a rust-encapsulating primer. Primer coverage verified at spec mil thickness and cured to tack-free before basecoat. Spot-test on modified bitumen cap-sheet granules to confirm adhesion.
Silicone (or acrylic, per spec) basecoat applied with airless sprayer at manufacturer-spec thickness — typically 10-15 dry mils for silicone. Coverage verified by 10-point wet-mil sampling per 1,000 sqft. Polyester fabric reinforcement embedded at critical seams, penetrations, and high-movement details. Basecoat cures 8-24 hours depending on humidity and ambient temperature — WNC's daily-thunderstorm window is built into the schedule.
Topcoat applied to reach total warranty-spec thickness — typically 25-30 dry mils for a 15-year silicone warranty, 35-40 for 20-year. Dry-mil thickness verified at 10 points per 1,000 sqft with a depth gauge and photo-documented. Manufacturer NDL warranty registered in the building owner's name. As-built drawings, mil-thickness log, warranty certificate, and maintenance schedule delivered.
Silicone and acrylic roof restoration across Buncombe County — aging TPO and EPDM on the I-26 corridor, metal-roof restoration on industrial inventory, and cold-storage envelope coatings. GAF Unisil, Gaco, and Henry NDL warranties registered on every install.
Aging TPO (15-22 years), I-26 corridor: the largest single coating opportunity in the Asheville market. The Fletcher / Arden / Mills River manufacturing and distribution spine carries a deep population of 2000s-era TPO now reaching end-of-warranty. Chalky surface is common and requires primer before a silicone basecoat. Silicone is preferred for the ponding-prone roofs typical of large WNC commercial envelopes. Typical project: $2.50-3.50/sqft for silicone with a 15-year NDL warranty.
Aging EPDM (20-30 years): the 1990s ballast-and-fully-adhered EPDM that reroofed much of WNC's 1960s-1980s commercial cohort is now well into restoration territory. Black EPDM accepts silicone with minimal primer; tape-seam failures must be re-taped or liquid-spliced first. Cost: $3-4/sqft for silicone. We don't recommend acrylic on EPDM — long-term adhesion is the issue.
Metal (galvanized, Galvalume, standing-seam): WNC's industrial, agricultural, and light-commercial inventory carries a great deal of aging metal, and metal restoration is among our highest-volume coating categories here. Power wash, localized rust treatment, rust-encapsulating primer, and seam-sealing with butyl tape plus elastomeric sealant precede the silicone topcoat. Typical project: $2.75-4/sqft — versus $14-22/sqft to replace the metal entirely.
Cold-storage and distribution envelopes: the I-26 cold-storage and distribution spine — anchored by the Ingles Markets climate-controlled distribution complex on the Swannanoa River, one of the largest cold-storage roof assets in the country — represents a distinct coating category. Vapor-retarder discipline matters on refrigerated envelopes that doesn't apply to dry-goods distribution-warehouse roofs, and coating restoration on these large roofs runs $3-4.50/sqft while deferring an eight-figure replacement.
Modified bitumen (SBS/APP, 15-25 years): common on the older WNC commercial and institutional inventory. Excellent primer-free silicone adhesion in most cases, though cap-sheet granules may need spot-removal for adhesion — we spot-test before full application. Cost: $3.50-5/sqft. When a roof doesn't qualify for coating at all, the alternative is full tear-off — see our roof coatings system page for the full substrate-by-substrate spec.
Western North Carolina is the home market — our crews dispatch out of Flat Rock in Henderson County, and the named-facility map below is the inventory we actually walk, survey, and restore in a typical month. For coatings specifically, the relevant sub-markets are the ones with large aging flat roofs and metal inventory: the I-26 manufacturing ring, the cold-storage and distribution spine, the brewery cluster, and the legacy commercial stock across the mountain towns. None of the below is a customer-list claim — it is the named-facility map of the market we operate inside, with the coating-restoration spec and cost pattern that goes with each. Permits run through City of Asheville Building Safety inside city limits and Buncombe County outside, with NCLBGC license filed on every commercial application per the North Carolina Licensing Board for General Contractors directory.
The I-26 manufacturing ring between Fletcher and Mills River is the densest coating-candidate corridor in WNC, because it holds the deepest population of 2000s-era TPO and aging metal-clad industrial roofs. Cummins-Meritor at Fletcher (the former Meritor commercial axle plant, acquired by Cummins in 2022 and now the company's largest North American manufacturing site, producing the majority of US Class 8 truck axles) carries the heaviest rooftop mechanical loading in the corridor — decades of bolt-on HVAC and process equipment leave a flashing-and-penetration map that any coating restoration has to re-detail before the field coat goes down. Eaton Corporation's Arden plant on Heywood Road (in continuous operation since the Westinghouse days in 1977, now producing low-voltage switchgear), the GF Linamar die-casting plant on Ferncliff Park Drive, BorgWarner on Brevard Road, and Nypro Asheville round out the corridor. Aging-TPO and metal restoration here runs $2.50-4/sqft for manufacturing facility coating work, scheduled around production so there's no shutdown — the entire appeal of coating over tear-off on an active plant is that the building stays dry and running through the work.
The I-26 cold-storage and distribution spine is the highest-value coating sub-market by roof area. Ingles Markets — the publicly-traded regional grocer headquartered on US 70 in Black Mountain — operates a climate-controlled distribution complex of roughly 840,000 square feet on the Swannanoa River, among the largest cold-storage roofs in the United States, that took direct flooding during Helene and ran one of the region's more visible commercial recoveries. Cold-storage roofs are prime restoration candidates precisely because their scale makes tear-off an eight-figure event; silicone restoration with proper vapor-retarder discipline defers that for 15 years. The Carquest Distribution Center on Old Shoals Road in Arden, the Mutual Distributing beverage warehouse on Oval Road, and the broader Arden / Fletcher distribution-warehouse cluster along I-26 between the Asheville Regional Airport and the Henderson County line add large dry-goods envelopes where aging-TPO coating runs $2.50-3.50/sqft.
The Asheville brewery cluster is an unusual coating sub-market because brewing process equipment loads steam, condensate, and CIP-chemical exposure onto both the underside of the deck and the rooftop. Sierra Nevada Brewing's 200-acre Mills River campus (a LEED Platinum East Coast brewery anchored by a large bottling-and-packaging warehouse, opened 2014) is the largest single brewery roof asset in WNC, with extensive flat-roof production envelope that is a natural silicone restoration candidate as the original membrane ages. New Belgium Brewing on Craven Street in the River Arts District (the riverfront site that took some of the most direct French Broad flooding during Helene) and Highland Brewing on Old Charlotte Highway add production-envelope roof inventory. Brewery coating work runs $3-4.50/sqft with enhanced underside-ventilation detail and a heavier detergent-wash step for the exhaust-drift zones.
The legacy commercial and metal-roof inventory across the mountain towns closes out the coating picture. Flat Rock and Hendersonville carry Henderson County medical-office, Main Street historic, and small-industrial stock; Balcrank Corporation in Weaverville, Altec Industries in Burnsville, and the broader Madison / Yancey / Transylvania perimeter hold aging metal-clad industrial roofs where restoration coating consistently beats replacement on cost. The 1960s-1980s strip-center, light-industrial, and small-office cohort across Black Mountain, Weaverville, Brevard, and Waynesville is the largest single population of coating-eligible roof inventory in the region — original built-up reroofed once with ballast EPDM in the 1990s, now at 25-35 year age and a candidate for either restoration coating or, where moisture has intruded, full EPDM or TPO tear-off. For owners across any of these sub-markets still working Helene claim cycles, the documentation package on our commercial insurance-claim page applies, and the underlying wind-and-water record is in the NC commercial storm-event dataset drawn from the NOAA Storm Events Database.
We run the thermal moisture survey, confirm substrate eligibility, and deliver a line-item comparison of silicone restoration versus full tear-off with clear NPV. If the substrate doesn't qualify, we tell you and scope the replacement instead. Local WNC contractor, 48-hour bid turnaround.
