Commercial Roof Coating Rahway, NJ
A roofing contractor in Rahway can restore a commercial roof with a coating system, to extend its life without a tear-off. Call (908) 562-6861 to reach a local roofer.
Coatings go on as a liquid and cure into one continuous layer over the old roof. They work over most roof types, from single-ply to metal, if the roof below is in decent shape. White coatings reflect sun and keep the roof cooler.
Coatings work best on roofs that are aging but not failing. If a moisture survey shows widespread wet insulation, that insulation has to be replaced first, or the roof is better off replaced. Sealing in moisture causes blisters and deck damage.
Not every coating suits every roof. Silicone is the pick for roofs that hold water, acrylic for well-drained roofs and urethane for heavy traffic. A thickness in mils is specified for each job, and the roofer can measure it with a gauge as the coating goes on.
Commercial Roof Coating is often paired with roof coating and spray foam roofing, depending on the cause.

The roof coating process
Here is how a typical commercial roof coating goes on.
Survey the roof
The survey checks for wet insulation and the overall roof condition. Wet areas are marked for removal. Test patches of coating are applied and pulled to check adhesion before the full job is planned.
Prep the surface
The roof is power washed to remove dirt, chalking and loose material. The surface dries completely before the next step. The crew also clears drains and scuppers so the finished roof sheds water freely.
Make repairs
All damage is repaired before coating. Rust on metal roofs is treated and primed. Backed-out screws on metal roofs are reset or replaced with oversized fasteners before any coating goes on.
Treat the seams
Seams, fasteners and flashings get reinforcing fabric or a base coat. Primers are used on surfaces like mod bit to stop staining.
Apply the coating
The roofer applies the coating in passes, checking thickness with a gauge. Weather limits apply, since rain or dew can ruin uncured coating. Air intakes on rooftop units are masked while the coating is sprayed.
Verify thickness
The roofer checks coverage and thickness at sample points. The coating details are recorded for future recoats.

Silicone Roof Coating Rahway, NJ
Silicone coatings resist ponding water and UV, which makes them popular on flat commercial roofs. It is usually applied in a single coat or two, at a thickness set by the job specification. Silicone does attract dirt, which can reduce reflectivity over time.
For Rahway building owners, the main trade-off with silicone is that future recoats have to be silicone too. Repairs to the underlying membrane also become harder once it is coated. Walk pads help with traction on silicone roofs.

Elastomeric Roof Coating Rahway, NJ
Elastomeric roof coating is the broad term for flexible coatings that stretch and recover as the roof expands and contracts. Acrylic is the most common elastomeric for well-drained roofs, and it stays bright white. For traffic-heavy roofs, urethane offers more durability.
Many Rahway metal roofs get acrylic elastomeric systems over treated fasteners and seams. Acrylic should not be used where water ponds, since standing water can soften it. The roofer matches the coating to the roof, its drainage and its use.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Rahway, NJ have the roof checked in the fall and again after the snow melts.

Commercial Roof Coating FAQ
How do I choose between silicone and acrylic coating?
The choice comes down mostly to drainage. Silicone handles ponding water and is common on flat roofs, while acrylic works on roofs that drain well, such as many metal roofs. Silicone generally requires silicone for future recoats, while acrylic can be recoated more easily.
Will coating my roof fix leaks?
Leak repairs come first, then the coating seals the surface. Coating over an active leak without fixing it can trap water and hide the problem. Wet insulation around the leak is replaced before coating.
Can any commercial roof be coated?
The best candidates are roofs that are aging but still dry and attached. TPO, EPDM, mod bit, built-up, metal and spray foam roofs can all be coated with the right prep and primer. If much of the insulation is wet, replacement is the better path.
What is the lifespan of a roof coating?
Coating life varies with type and thickness, often landing between 10 and 20 years. Thicker applications last longer, and many coatings can be recoated when they wear. Regular inspections help spot wear before the roof underneath is exposed.
Does a white roof coating lower cooling costs?
A white coating reflects much of the sun, lowering roof surface temperatures. Less heat reaches the space below, which can reduce air conditioning use. Dirt reduces the effect over time.
