Roof Coating in Hillsborough, NJ — Hillsborough Roofing Pros

What Roof Coating Involves

Roof coating is a liquid-applied elastomeric membrane that bonds with your existing roofing surface to create a seamless, reflective barrier. For commercial low-slope roofs in Hillsborough, we typically install silicone coatings (e.g., GAF Unisil) for superior ponding water resistance, or acrylic elastomerics (e.g., Henry 887) for cost-effective UV protection on well-drained decks. Polyurethane base coats are used over aged modified-bitumen or built-up roofs to bridge hairline cracks. Every job includes a primer system — usually a water-based acrylic primer for asphalt surfaces or a solvent-based primer for smooth metal. We apply coatings at 20–30 mils dry film thickness using spray or roller, ensuring proper coverage over flashings, parapets, and penetrations. ASTM D6083 testing is performed on acrylic systems to verify elongation and tensile strength.

Signs You Need Roof Coating

For commercial building owners in Hillsborough, these symptoms indicate your roof membrane needs restoration rather than full replacement:

• Ponding water remaining 48 hours after rain — silicone coatings self-seal in standing water conditions.
• Membrane seam separation or alligatoring on modified-bitumen roofs — coating bridges gaps without tear-off.
• Blistering or fishmouths in built-up roofing — polyurethane primer fills voids before topcoat.
• Flashing pull-away at parapet walls — coating re-bonds flashings and terminates into reglets.
• Ballast displacement on gravel-surfaced roofs — coating encapsulates gravel and restores reflectivity.
• Interior staining at column lines indicating slow leaks — coating stops water intrusion at the membrane level.

Our Roof Coating Process

Step 1: Roof Asset Survey. We measure your roof’s square footage, slope, drainage points, and existing membrane type. We document all penetrations, curbs, and flashings with photos and note any areas of ponding or deterioration.

Step 2: Specification Review. Based on the survey, we select the appropriate coating system — silicone for ponding-prone areas, acrylic for well-drained roofs, or a polyurethane base for crack bridging. We provide a written specification including dry mil thickness, primer type, and manufacturer warranty terms.

Step 3: Surface Preparation. We power-wash the roof to remove dirt, algae, and loose gravel. For modified-bitumen roofs, we apply a primer to promote adhesion. We caulk all seams, flashings, and penetrations with a compatible sealant.

Step 4: System Installation. We apply the coating in one or two coats using spray equipment for even coverage. We stripe all flashings and terminations with a brush to ensure full encapsulation. Curing time is typically 24–48 hours depending on temperature and humidity.

Step 5: Final Inspection & Warranty Enrollment. We perform a wet-mil thickness check at 10 locations per 1,000 square feet. We provide a written warranty certificate from the manufacturer (typically 10–15 years for NDL warranties) and a final condition report with photos.

Cost Considerations in Hillsborough

For commercial roof coating in Hillsborough, pricing ranges from $2.50 to $5.00 per square foot for acrylic systems and $3.50 to $6.50 per square foot for silicone systems, depending on substrate condition and number of penetrations. A typical 10,000-square-foot warehouse roof coating runs $28,000 to $65,000. Primer systems add $0.30–$0.60 per square foot. Costs include surface preparation, primer, coating application, and manufacturer warranty registration. We do not charge for the initial roof asset survey or specification review.

Warranty & Insurance

We offer manufacturer-backed NDL (No Dollar Limit) warranties from GAF Unisil and Henry that cover material defects and labor for 10–15 years, depending on system selection. Our liability insurance covers up to $2 million per occurrence, and we provide certificates of insurance upon request. For Hillsborough commercial properties, we can also assist with insurance claim documentation if coating is applied as part of a storm-damage restoration plan — we provide detailed photo evidence and moisture meter readings to support your claim.
