What Is Silicone Roof Coating?
Silicone roof coating is a liquid-applied silicone membrane that restores a low-slope or flat roof in place, sealing seams, splits, and flashings under one monolithic surface. The hydrophobic silicon-oxygen backbone resists ponding water without softening and reflects sunlight to lower roof surface temperature.
What Silicone Roof Coating Do We Provide?
Newark Quality Roofing restores low-slope and flat commercial roofs across Essex County with silicone roof coating, a liquid-applied silicone membrane governed by ASTM D6694 that seals seams, splits, and flashings under one monolithic surface. Silicone roof coating recoats an existing roof in place rather than tearing it off, extending service life at a fraction of replacement cost and keeping the old roof out of landfill, per the RCMA.
Silicone roof coating cures by reacting with atmospheric moisture as a single-component moisture-cure system, which allows application in colder and higher-humidity conditions than water-evaporation acrylics, per Henry and the RCMA. A 100% silicone coating carries a hydrophobic silicon-oxygen backbone that resists permanent and standing water without softening or losing adhesion, the property that separates silicone restoration from water-based coatings on ponding-prone Essex County flat roofs, per the RCMA, Gaco, Tremco, Henry, and GE/Momentive.
- Ponding-resistant silicone restoration — Ponding-resistant silicone restoration coats a flat roof where water stands after rain, because a 100% silicone coating resists permanent and standing water without softening, while water-based acrylic re-emulsifies under continuous immersion, per the RCMA, Gaco, Tremco, and Henry.
- Reflective cool-roof silicone coating — Reflective cool-roof silicone coating lowers roof surface temperature with an initial solar reflectance near 0.80 to 0.88 and thermal emittance near 0.85 to 0.92, per the CRRC, Henry, and Mule-Hide, with a reflective roof staying more than 50°F cooler than a conventional roof on a sunny afternoon, per the DOE.
- Seam, split, and flashing reinforcement — Seam, split, and flashing reinforcement repairs and embeds reinforcing fabric at the details before the field coat, because even ponding-resistant silicone needs a clean dry surface and reinforced details, per the RCMA, Gaco, and Henry.
- Silicone recoat of an existing coated roof — Silicone recoat of an existing coated roof renews a maintained silicone roof at the 15 to 20 year interval, because cured silicone is recoated with silicone rather than torn off, and a recoated roof is recoated again, per the RCMA and Gaco.
- Spray polyurethane foam recoat — Spray polyurethane foam recoat reapplies the protective silicone topcoat that keeps a UV-sensitive SPF roof serviceable, on a recoat cycle near 15 to 20 years for silicone, per the SPFA and manufacturer guidance.
How Do You Know If You Need Silicone Roof Coating?
- Standing water that ponds on a flat roof section more than 48 hours after rain marks a roof for silicone restoration, because a 100% silicone coating resists permanent and standing water without softening, while a flat roof needs at least ¼ inch per foot of slope to drain, per the RCMA and NRCA.
- Aging seams, splits, and lifted flashings leaking across the field signal a coating candidate, because silicone roof coating seals every seam and detail under one monolithic membrane rather than chasing individual repairs, per the RCMA.
- A dark or weathered low-slope roof driving high peak-summer cooling demand favors a reflective silicone coating, because a cool roof reduces peak cooling demand by 11 to 27% in air-conditioned residential buildings, per the EPA.
- A prior water-based acrylic coating that has softened, chalked, or washed off in ponded areas indicates the wrong chemistry for the roof, because acrylic re-emulsifies under continuous immersion and most acrylic warranties exclude ponded areas, per the RCMA and Western Colloid.
- A sound roof deck and dry insulation under a deteriorated membrane surface makes restoration the economical path, because recoating extends service life at a fraction of tear-off cost and avoids landfill, per the RCMA.
- A spray polyurethane foam roof with an eroded topcoat needs recoating, because foam is UV-sensitive and stays serviceable only while the protective coating is maintained, on a silicone recoat cycle near 15 to 20 years, per the SPFA and NRCA.

How Do Our Roofing Contractors Perform Silicone Roof Coating?
Newark Quality Roofing cleans and dries the roof, repairs the seams, splits, and flashings, and runs an adhesion test before any field coat, because a clean dry surface and reinforced details govern coating performance. Newark Quality Roofing pressure-washes the roof and lets the surface dry fully, because a primer is no substitute for thorough cleaning, per the RCMA, Gaco, and Henry. Newark Quality Roofing verifies adhesion before full application with a 24-hour adhesion test, and an aged asphalt surface takes an epoxy primer to stop bleed-through, per Gaco.
Newark Quality Roofing applies high-solids silicone to the manufacturer dry-film thickness, near 1.5 gallons per 100 square feet for roughly 22 dry mils, because warranty term scales with film thickness. Silicone roof coating is high-solids near 90% with low shrinkage, so one application reaches the specified thickness, per Gaco, Henry, and Mule-Hide. A renewable warranty term scales with dry-film thickness, near 10 to 15 years at 20 to 22 mils and 15 to 20 years at 30 mils, per the RCMA, Henry, Mule-Hide, and Gaco.
Newark Quality Roofing coats for reflectance and surface-temperature reduction, not for added insulation, because a silicone coating changes surface radiative properties rather than conductive resistance. A white silicone coating carries an initial solar reflectance near 0.80 to 0.88 and emittance near 0.85 to 0.92, per the CRRC, Henry, and Mule-Hide, and reflectance drops faster than emittance as silicone holds dirt, near 0.88 to 0.73 at 3 years for Henry Tropi-Cool, per the CRRC and Henry. A silicone coating adds no meaningful R-value, and energy benefit comes from reflectance and a lower roof surface temperature, never from insulation, per the RCMA, DOE, and CRRC.
What Residential Silicone Roof Coating Do We Provide?
Newark Quality Roofing coats residential low-slope and flat roof sections across Essex County — porch, garage, addition, and row-home flat roofs — with a silicone membrane that seals the aging seams and flashings where these sections leak. A repair of the roof covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, per the NJ Uniform Construction Code.
A residential silicone coating resists the standing water that collects on a low-slope porch or addition roof, because a 100% silicone coating resists permanent and standing water without softening, per the RCMA and Gaco. The reflective white surface reduces peak-summer heat gain through the flat section, because a cool roof reduces peak cooling demand by 11 to 27% in air-conditioned residential buildings, per the EPA, with a smaller net annual benefit in Newark’s heating-dominated Climate Zone 4 to 5, per the DOE.
What Commercial Silicone Roof Coating Do We Provide?
Newark Quality Roofing restores commercial low-slope roofs across Essex County with silicone roof coating, recoating an existing membrane or spray-foam roof in place rather than tearing it off and sending it to landfill. Recoating extends service life at a fraction of tear-off and replacement cost and avoids landfill disposal, per the RCMA, and a maintained silicone roof is recoated at the 15 to 20 year interval rather than replaced, per the RCMA and Gaco.
A commercial silicone coating resists the ponding common on a large low-slope roof, because a 100% silicone coating resists permanent and standing water without softening, while a flat roof needs at least ¼ inch per foot of slope to drain, per the RCMA and NRCA. The reflective coating lowers membrane temperature and extends membrane life, and the cool-roof reflectance is listed by the CRRC under ASTM C1549 rather than the retired ENERGY STAR roof program, per the CRRC and EPA.
A commercial coating is typically classified as maintenance rather than a capital improvement, per the RCMA, though the RCMA defers the tax treatment to the building owner’s tax professional. Newark Quality Roofing applies silicone systems from Gaco, Henry, and Mule-Hide and recoats cured silicone with silicone, because cured silicone is not recoated with acrylic or urethane, per Gaco and the RCMA.
What Are the Steps in Our Silicone Roof Coating Process?
- Roof Inspection and Coating-Candidate Assessment
A Newark Quality Roofing technician inspects the membrane, seams, flashings, and drainage and confirms the deck and insulation are sound, because recoating fits a roof with surface deterioration over a sound deck, per the RCMA.
- Cleaning and Drying
A Newark Quality Roofing crew removes debris, pressure-washes the roof, and lets the surface dry fully, because a primer is no substitute for thorough cleaning and even ponding-resistant silicone needs a clean dry surface, per the RCMA, Gaco, and Henry.
- Detail Repair and Reinforcement
A Newark Quality Roofing crew repairs seams, splits, and flashings and embeds reinforcing fabric at the details, because the seams and flashings are the most common leak points and silicone seals them under one monolithic membrane, per the RCMA.
- Adhesion Test and Primer
A Newark Quality Roofing crew verifies adhesion before full application with a 24-hour adhesion test and primes where the substrate requires it, because an aged asphalt surface takes an epoxy primer to stop bleed-through, per Gaco.
- Silicone Field Application
A Newark Quality Roofing crew sprays high-solids silicone near 1.5 gallons per 100 square feet to roughly 22 dry mils, because warranty term scales with dry-film thickness, near 10 to 15 years at 20 to 22 mils and 15 to 20 years at 30 mils, per the RCMA, Henry, Mule-Hide, and Gaco.
- Thickness Verification and Warranty
A Newark Quality Roofing lead confirms the dry-film thickness against the manufacturer specification, documents uniform coverage, and processes the manufacturer warranty, the term that scales with the verified film thickness, per the RCMA and Henry.
