What Is Silicone Elastomeric Roof Coating?
Silicone elastomeric roof coating is a liquid-applied membrane that stretches and recovers to accommodate the daily thermal movement of a low-slope roof, sealing it under one monolithic surface. The chemistry — silicone, acrylic, or polyurethane — is matched to the roof's ponding, dirt-pickup, and movement conditions.
What Silicone Elastomeric Roof Coating Do We Provide?
Newark Quality Roofing applies silicone elastomeric roof coating across Essex County and matches the coating chemistry to the roof, because the RCMA recognizes 3 liquid-applied elastomeric coating chemistries: silicone (ASTM D6694), acrylic (ASTM D6083), and polyurethane (ASTM D6947) — for low-slope commercial and flat residential roofs. An elastomeric roof coating is a liquid-applied membrane that stretches and recovers to accommodate the daily thermal movement of the roof, the property that separates an elastomeric coating from a rigid film.
Elastomeric describes the high elongation of the cured film: a Simiron TEKTOP silicone coating reaches 279% elongation per ASTM D412, and an Acrymax AF-130FR acrylic coating reaches 220% per ASTM D2370, the manufacturer datasheet values that show each chemistry exceeds elastomeric minimums, per Simiron and Acrymax product data. A silicone elastomeric coating cures by reacting with atmospheric moisture, a single-component moisture-cure that allows colder and higher-humidity application than a water-evaporation acrylic, per Henry and the RCMA, so a Newark Quality Roofing coating selection starts with the roof condition rather than the product.
- Silicone elastomeric coating — Silicone elastomeric coating uses a moisture-cure silicone chemistry under ASTM D6694, the high-solids choice that resists permanent standing water without softening, because the hydrophobic Si-O backbone stays stable in water, UV, and heat, per the RCMA, Gaco, Henry, and GE/Momentive.
- Acrylic elastomeric coating — Acrylic elastomeric coating uses a water-dispersed acrylic latex under ASTM D6083, the recoatable choice that re-washes cleaner with rainfall and holds reflectance longer on a draining roof, because acrylic re-emulsifies under continuous immersion and most acrylic warranties exclude ponded areas, per the RCMA and Western Colloid.
- Polyurethane elastomeric coating — Polyurethane elastomeric coating uses an ASTM D6947 chemistry with a tensile floor of 1,500 psi, the abrasion-resistant choice for high-traffic detail areas, per the RCMA.
- Elastomeric chemistry selection — Elastomeric chemistry selection matches the coating to the roof: silicone over acrylic when ponding or standing water is present, and acrylic over silicone when dirt-pickup and recoatability matter, because silicone holds dirt and loses reflectance faster while acrylic re-washes cleaner, per the RCMA, Henry, and Mule-Hide.
How Do You Know If You Need Silicone Elastomeric Roof Coating?
- A weathered but structurally sound low-slope membrane with no widespread saturation suits an elastomeric coating, because a maintained coated roof is recoated rather than replaced at a fraction of tear-off cost and avoids landfill, per the RCMA.
- Ponding or standing water that lingers on a low-slope roof points to a silicone elastomeric coating over an acrylic, because water-based acrylic re-emulsifies under continuous immersion and most acrylic warranties exclude ponded areas, per the RCMA and Western Colloid.
- A dust-prone or tree-shaded roof where reflectance loss from dirt-pickup matters points to an acrylic elastomeric coating, because acrylic re-washes cleaner with rainfall while silicone holds dirt and loses reflectance faster, per the CRRC, Henry, and Mule-Hide.
- Daily thermal expansion and contraction opening hairline cracks at seams and details suits an elastomeric coating, because the cured film stretches to 220–279% elongation and recovers, per Acrymax and Simiron datasheet values measured under ASTM D2370 and ASTM D412.
- A dark low-slope roof that drives high summer surface temperature suits a white elastomeric coating, because a white silicone or acrylic coating carries an initial solar reflectance near 0.80–0.88, per the CRRC, which a cool roof uses to reduce peak summer cooling demand by 11–27% in air-conditioned residential buildings, per the EPA.
- Open seams, splits, and flashing details on an otherwise serviceable membrane suit a reinforced elastomeric coating, because the RCMA directs repair and reinforcement of seams, splits, and flashing before the field coat, per the RCMA, Gaco, and Henry.

How Do Our Roofing Contractors Perform Silicone Elastomeric Roof Coating?
Newark Quality Roofing selects the elastomeric chemistry from the roof condition, applying the silicone-over-acrylic-when-ponding and acrylic-over-silicone-when-dirt-pickup-matters decision before any coating reaches the roof. Silicone over acrylic governs a ponding roof, because 100% silicone resists permanent standing water without softening while water-based acrylic re-emulsifies under continuous immersion and most acrylic warranties exclude ponded areas, per the RCMA and Western Colloid. Acrylic over silicone governs a draining dust-prone roof, because acrylic re-washes cleaner with rainfall while silicone holds dirt and loses reflectance faster — a Henry Tropi-Cool silicone drops from 0.88 to 0.73 over 3 years while a Mule-Hide A-300 acrylic drops from 0.87 to 0.75, per the CRRC, Henry, and Mule-Hide.
Newark Quality Roofing cleans the membrane, repairs and reinforces the details, then applies the elastomeric coating to the dry-film thickness that sets the warranty length. A coated roof needs a clean, fully dry surface with seams, splits, and flashing repaired and reinforced before the field coat, because a primer is no substitute for thorough cleaning, per the RCMA, Gaco, and Henry. A high-solids silicone near 90% solids often covers in one coat while a lower-solids acrylic near 50–60% solids usually needs two coats, and the renewable warranty scales with the dry-film thickness on a 10/15/20-year scale, per the RCMA, Gaco, Henry, and Mule-Hide.
Newark Quality Roofing frames the elastomeric coating as a reflectance upgrade, not an insulation upgrade, because a coating adds negligible R-value. An elastomeric coating changes the surface radiative properties — solar reflectance and thermal emittance, with white coatings near 0.85–0.92 emittance per the CRRC and Mule-Hide — and the energy effect comes from a lower roof surface temperature, never from added insulation, per the RCMA, the DOE, and the CRRC. A reflective roof reduces peak summer cooling demand but carries a winter heating penalty in Newark, an IRC Climate Zone 4–5 heating-dominated climate, so the net annual benefit depends on insulation and climate, per the DOE and the RCMA.
What Residential Silicone Elastomeric Roof Coating Do We Provide?
Newark Quality Roofing applies silicone elastomeric roof coating on residential flat and low-slope sections across Essex County — row-home flat roofs, porch and garage low-slope roofs, and multi-family flat roofs. A residential coating selection matches silicone to a ponding section and acrylic to a draining dust-prone section, and a repair or recoat 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 elastomeric coating restores a weathered but sound low-slope section at a fraction of tear-off cost and avoids landfill, per the RCMA, and a white coating carries an initial solar reflectance near 0.80–0.88, per the CRRC. The cool-roof reflectance reduces peak summer cooling demand by 11–27% in air-conditioned residential buildings, per the EPA, while carrying a winter heating penalty in Newark, an IRC Climate Zone 4–5 heating-dominated climate, so a Newark Quality Roofing coating selection weighs the net annual benefit against insulation and climate, per the DOE.
What Commercial Silicone Elastomeric Roof Coating Do We Provide?
Newark Quality Roofing applies silicone elastomeric roof coating on commercial low-slope membranes and spray-foam roofs across Essex County, selecting the chemistry from the ponding, dirt-pickup, and thermal-movement condition of the roof. A 100% silicone coating resists permanent standing water without softening, per the RCMA, Gaco, and GE/Momentive, while an acrylic coating re-washes cleaner on a draining roof, so a Newark Quality Roofing commercial scope matches silicone to a ponding roof and acrylic to a draining one.
A commercial recoat renews a spray-polyurethane-foam or single-ply roof on a cycle of roughly 10–15 years for acrylic and 15–20 years for silicone, per SPFA and RCMA guidance, and a recoated roof is recoated again rather than torn off. A cured silicone coating is recoated only with silicone, because switching away from silicone generally requires removal first, per Gaco and the RCMA. The RCMA classifies a coating as maintenance and defers the tax treatment to the owner's tax professional, so Newark Quality Roofing names the framing rather than the outcome.
What Are the Steps in Our Silicone Elastomeric Roof Coating Process?
- Roof Assessment and Chemistry Selection
A Newark Quality Roofing technician assesses the membrane, the ponding pattern, and the dirt-pickup exposure, then selects silicone for a ponding roof and acrylic for a draining dust-prone roof, because acrylic re-emulsifies under immersion while silicone holds dirt, per the RCMA, Western Colloid, and Mule-Hide.
- Adhesion Test
A Newark Quality Roofing crew verifies coating adhesion before full application, because an aged asphalt surface takes an epoxy primer to stop bleed-through, with a 24-hour adhesion-test result confirming the bond, per Gaco.
- Cleaning and Drying
A Newark Quality Roofing crew removes debris and carefully pressure-washes the roof, then lets the surface dry fully, because a primer is no substitute for thorough cleaning and even a ponding-resistant silicone needs a clean dry surface, per the RCMA, Gaco, and Henry.
- Detail Repair and Reinforcement
A Newark Quality Roofing crew repairs and reinforces the seams, splits, and flashing details before the field coat, because the elastomeric film stretches to 220–279% elongation across moving details, per the RCMA and the Acrymax and Simiron datasheet values under ASTM D2370 and ASTM D412.
- Field Coating to Dry-Film Thickness
A Newark Quality Roofing crew applies the field coat to the dry-film thickness that sets the warranty, with a high-solids silicone near 90% solids often covering in one coat and a lower-solids acrylic near 50–60% solids usually needing two coats, per Gaco, Henry, and Mule-Hide.
- Verification and Renewable Warranty
A Newark Quality Roofing lead verifies the cured film and dry-film thickness, then registers the renewable warranty on the 10/15/20-year scale that lengthens with thickness, the coating a maintained roof recoats again rather than replaces, per the RCMA, Henry, and Mule-Hide.
