What Roof Coating Involves

Roof coating is not a paint job. It's a engineered membrane system that bonds to your existing roof — whether that's TPO, EPDM, metal, or built-up asphalt. We start with a power wash to remove dirt, algae, and loose granules. Then we prime any bare metal or repaired areas. The coating itself is applied in two coats, at 20–25 mils dry film thickness, using a spray rig or rollers.

Materials matter. Silicone coatings are the go-to for ponding water — they're moisture-tolerant and don't need a primer on most substrates. Acrylic elastomerics are cheaper and reflect UV well, but they need good drainage and a dry surface. Polyurethane is the toughest, often used as a base coat over foam or in high-traffic areas. We'll spec the right system for your roof, not just the cheapest one.

Signs You Need Roof Coating

Your roof is telling you it needs attention. Look for ponding water that stays 48 hours after a rain — that's a sign the membrane is sagging or the drainage is failing. Seam separation at the laps, blistering or alligatoring on the surface, flashing pulling away at the parapet — these are all openings for water to seep in.

Inside the building, check for staining along column lines or near the roof drains. If you see any of this, the roof is at end-of-life wear, but it's not necessarily ready for tear-off. Roof coating can restore it — if we catch it before the deck rots or the insulation delaminates.

Our Roof Coating Process

Roof asset survey. We walk the entire roof, map every penetration, and document existing conditions with photos.
Specification review. We pull the original roof specs, check the warranty status, and determine if coating is the right call — sometimes it isn't.
Surface prep. Power wash, scrape, prime, and repair any blisters or open seams. This is 60% of the job and we don't skip it.
System install. Two coats of coating, reinforced at seams and details with fabric or seam tape. We use ring-shank nails for any loose flashing, and we hand-seal every penetration.
Final inspection. We walk it with you, show you the wet film thickness readings, and register your warranty.

Cost Considerations in Hillsborough

Roof coating runs $4.00–$8.00 per square foot for silicone systems, installed. Acrylics are a bit less, polyurethane a bit more. For a typical 10,000 sq ft commercial roof, that's $40,000–$80,000 — but compare that to a full replacement at $15–$25 per square foot, plus the disruption of a tear-off. Coating is usually half the cost and can be done without shutting down your operations.

In Hillsborough, the climate matters. Heavy snow and ice dam risks in winter mean the coating has to handle freeze-thaw cycles. Humid summers promote algae and moss growth on roofs — a silicone system resists that better than acrylic. We'll factor all that into the spec.

Warranty & Insurance

Manufacturer warranties for roof coating run 10–20 years, depending on the system. We use GAF Unisil, Henry, and Tropical Roofing products — all of which offer NDL (no-dollar-limit) warranties when installed by an approved contractor. That means the manufacturer covers material and labor for the full term, not just a pro-rated amount.

If your roof has storm damage, we'll document it for your insurance claim. We work with your adjuster, provide photos and moisture readings, and make sure the coating work is covered — not just the temporary tarp.

Ponding Water

Water standing 48 hours after rain is a red flag. It means the membrane is sagging or the drains are blocked — and that water is wicking into the insulation.
