Overview
Silicone roof coating is a liquid-applied, fully adhered roof restoration system that transforms aging flat and low-slope roofs into high-performance, reflective, waterproof surfaces without the cost and disruption of a full roof replacement. Applied as a liquid that cures into a seamless, flexible membrane, silicone coating bridges cracks, seals seams, and creates a continuous waterproof barrier across the entire roof surface. For property owners in the Newark and Essex County area, silicone coating represents one of the most cost-effective approaches to extending the life of a flat roof by 10 to 20 years while simultaneously improving energy efficiency through its highly reflective white surface that reduces cooling costs by reflecting solar radiation away from the building.
Unlike acrylic and other water-based roof coatings that can wash off during cure and degrade in standing water, silicone coatings are moisture-cured and remain stable in ponding water conditions, making them the superior choice for flat roofs in New Jersey where heavy rainfall events are common and some degree of ponding is inevitable despite proper drainage design. Silicone also maintains its flexibility and reflectivity over time without chalking, cracking, or becoming brittle, even through the extreme temperature swings our region experiences between summer and winter seasons.
Newark Quality Roofing has applied silicone roof coatings to hundreds of flat and low-slope roofs throughout Essex County, giving us deep experience in surface preparation, application techniques, and the long-term performance of these systems under real New Jersey weather conditions. We work with premium silicone coating products from manufacturers who back their systems with comprehensive warranties, and we follow strict application protocols that ensure the coating achieves the thickness, adhesion, and coverage necessary for reliable long-term performance.
The environmental advantages of silicone coating extend beyond energy savings from the reflective surface. By restoring an existing roof rather than tearing it off and replacing it, coating eliminates the landfill waste generated by full replacement, which can amount to several tons of material for a typical commercial building. The reduced material and labor requirements also lower the carbon footprint of the project compared to new construction. For property owners pursuing sustainability goals or LEED certification, silicone coating restoration earns credits for waste diversion, reduced material use, and enhanced energy performance, combining environmental responsibility with sound financial management.

Signs Your Flat Roof Is a Candidate for Silicone Coating
- Your flat or low-slope roof membrane is aging and showing surface deterioration such as cracking, crazing, or granule loss, but the underlying structure and insulation are still in good condition, making full replacement premature.
- Seams, flashings, and penetrations on your flat roof are developing leaks as the original adhesives and sealants age, creating multiple small leak points across the roof surface that individual repairs cannot keep up with.
- Your energy bills are higher than expected because the dark-colored or weathered roof surface absorbs solar heat, transferring it into the building and forcing air conditioning systems to work harder during warm months.
- Water ponds on sections of your flat roof for extended periods after rainfall, creating areas of concentrated moisture exposure where most coating types would fail but silicone maintains its integrity.
- Previous roof coating applications have failed, chalked, or washed off, possibly because a water-based acrylic product was used that could not withstand ponding water conditions common on your roof.
- You want to extend your roof's lifespan without the major capital expenditure, tenant disruption, and construction waste associated with a full tear-off and replacement.

Professional Silicone Roof Coating Application
Surface preparation is the single most important factor in the long-term success of any roof coating application, and we invest significant time and effort in this critical step. The existing roof surface must be clean, dry, and free of all contaminants, loose material, and failed previous coatings before silicone application. We use commercial pressure washing, scraping, and priming to prepare the substrate, and we perform adhesion testing to verify that the silicone will bond properly to the existing membrane material.
Repairs to the existing roof are completed before coating application. All damaged sections, failed seams, cracked flashings, and deteriorated penetration seals are repaired or replaced using compatible materials. These pre-coating repairs are essential because the silicone coating seals over the existing surface, and any defects left beneath it will eventually telegraph through and compromise the coating system. We also address drainage issues, adding tapered insulation or crickets where ponding water indicates inadequate slope.
The silicone coating is applied in multiple coats to achieve a uniform total thickness that meets the manufacturer's specification for full warranty coverage, typically 20 to 30 mils dry film thickness. We use airless spray equipment for uniform application on large field areas and roller application for detail areas around penetrations, edges, and flashings. Reinforcing fabric is embedded in the coating at seams, transitions, and other high-stress areas to provide additional crack-bridging capability.
The completed coating system creates a seamless, UV-resistant, highly reflective surface that waterproofs the entire roof while reflecting up to 85 percent of solar energy. This dual benefit of waterproofing and energy savings makes silicone coating one of the highest-return roof improvements available for flat and low-slope buildings in our climate. The bright white finish also enhances visibility for rooftop maintenance personnel working during daylight hours, improving safety on the roof surface.
Silicone Roof Coating for Residential Properties
Many homes in the Newark area have flat or low-slope roof sections over additions, garages, porches, and contemporary-design main roofs that are prime candidates for silicone roof coating. These residential flat roof areas often develop leaks at aging seams and flashings, and homeowners face the choice between expensive full replacement and a more economical coating restoration that can extend the roof's service life by a decade or more while improving its weather resistance and energy performance.
Silicone coating is particularly valuable for residential flat roofs because it eliminates every seam, lap, and penetration seal on the existing roof surface under a continuous, monolithic membrane. This is important because the seams and laps in flat roofing membranes are the most common leak sources, and coating over them with reinforced silicone provides a level of waterproofing that the original installation may not have achieved. The reflective white surface also reduces heat gain through flat roof sections, keeping rooms below noticeably cooler in summer.
Our residential silicone coating projects are typically completed in one to two days with minimal disruption to your household. There are no heavy materials to hoist, no loud tear-off demolition, and no construction debris to manage. The coating cures to foot traffic within hours and reaches full performance within a day, making it one of the quickest and least disruptive roof improvements available.
Commercial Silicone Roof Coating Solutions
For commercial building owners and property managers, silicone roof coating offers a compelling alternative to full roof replacement that saves 50 to 70 percent of replacement cost while providing comparable waterproofing performance and superior energy efficiency. Commercial flat roofs are the ideal application for silicone coating because of their large, relatively unobstructed surfaces that can be coated efficiently, and because the energy savings from the reflective coating surface scale directly with roof area.
The business case for commercial silicone coating extends beyond direct cost savings. By avoiding full tear-off, you eliminate business disruption from construction noise and activity, avoid landfill disposal of old roofing materials, and complete the project in a fraction of the time required for replacement. Many commercial silicone coating projects can be performed over weekends or during off-hours without any impact on daily business operations, which is particularly valuable for retail, medical, and hospitality properties.
We work with commercial clients to schedule coating projects during optimal weather windows and phase large projects to accommodate building operations. Our commercial coating applications come with manufacturer-backed warranties of 10 to 20 years depending on the coating system and thickness specified, giving you long-term assurance of waterproofing performance.
For commercial property managers evaluating capital expenditure versus operating expense treatment, silicone coating often qualifies as a maintenance expenditure rather than a capital improvement, allowing the full cost to be expensed in the year of application rather than depreciated over the roof's remaining life. This tax treatment distinction can significantly improve the after-tax return on coating projects compared to full replacement, which must be capitalized. We recommend consulting your tax advisor to confirm the appropriate treatment for your specific situation and building classification.
Our Process
Roof Inspection and Condition Assessment
We thoroughly inspect the existing roof membrane, seams, flashings, penetrations, and drainage to determine if the roof is a suitable candidate for coating restoration. Core samples may be taken to assess insulation condition and moisture content.
Surface Preparation
The roof is pressure washed, cleaned of all debris and contaminants, and allowed to dry completely. Failed seams, damaged areas, and deteriorated flashings are repaired with compatible materials before coating.
Primer Application
Where required by the manufacturer for the specific substrate type, primer is applied to ensure optimal adhesion between the existing membrane and the silicone coating system.
Reinforcement and Detail Work
Polyester reinforcing fabric is embedded in the coating at all seams, penetrations, transitions, and high-stress areas. This fabric provides additional strength and crack-bridging capability at these vulnerable locations.
Silicone Coating Application
Multiple coats of silicone coating are applied using airless spray equipment to achieve the specified total dry film thickness. Each coat is applied uniformly and allowed appropriate cure time before the next application.
Quality Inspection and Warranty
Final thickness measurements verify specification compliance. The completed system is inspected for uniform coverage and proper detail work. Manufacturer warranty documentation is processed and provided to the building owner.
