Roof Coating Maplewood, NJ
A roofer in Maplewood can apply a liquid roof coating, usually silicone or acrylic, over a flat, low-slope or metal roof that is weathered but still dry and structurally sound, and a moisture check comes first, because coating over wet insulation traps the problem. Call (973) 858-1830 to reach a local roofer.
Think of a coating as a new, seamless surface layer fused to an aging roof. The coating covers weathered surfaces, seams and fastener heads and blocks the sunlight that ages roofing materials. White coatings reflect much of the sun's heat, so the roof surface runs cooler in summer.
Coatings work best on low-slope and metal roofs, not on most asphalt shingle roofs. Common substrates include rubber and TPO membranes, torch-down or self-adhered mod bit, built-up roofs, foam and metal panels. On shingle roofs, coatings are generally avoided because they can hold moisture and interfere with how shingles shed water.
The most important question before coating is whether water is already trapped in the roof. Trapped moisture under a fresh coating leads to blisters, rot and a roof that fails from the inside. Expect the roofer to test for moisture before recommending a coating at all.
If the problem goes deeper than it first looked, a Maplewood roofer may also recommend flat roof repair or metal roof coating.

Call nowThe process
The roof coating process
Most of a coating job is preparation, not spraying.
Check for moisture
Before anything else, the roof is tested for trapped water. Any soaked areas must be removed and replaced first.
Clean the surface
A thorough wash strips away dirt, algae and chalky residue. Loose gravel or debris is removed so the surface is bare.
Make repairs
Open seams, blisters, splits and failed flashing are repaired, and exposed fasteners on metal are tightened or replaced with oversized screws. Problems not fixed now will be buried under the coating.
Apply primer
A primer or bonding coat goes on where the coating maker requires it. Skipping primer is a common cause of peeling.
Coat the roof
Detail work around seams and penetrations comes first, followed by the base and top coats. Rain or dew before curing can wash out acrylic, so timing is important.
What is included
Parts of a roof coating

Silicone, acrylic or another coating applied to the specified thickness matched to the roof material.

Roof Restoration Maplewood, NJ
A roof restoration repairs and renews an existing roof so it can keep working instead of being replaced. Expect it to include repairs to seams, flashing, drains and fasteners, followed by a complete coating. The main benefit is avoiding the disruption of a full tear-off.
Restoration only works while most of the roof is still dry and attached. A roof with scattered surface wear and a few small leaks is a strong candidate, while one with soaked insulation, widespread blisters or rotted deck is not. Have the roofer walk you through the findings before deciding between restoring and replacing.

Flat Roof Coating Maplewood, NJ
Flat roofs benefit most from coatings because their seams and surfaces take constant sun and occasional ponding. The choice usually comes down to silicone for roofs that hold some water and acrylic for roofs that drain quickly. The coating is matched to the existing membrane, so EPDM, TPO, mod bit and built-up roofs each have their own primers and products.
Drainage should be checked before any flat roof coating. Clogged drains, blocked scuppers and low spots that hold water for days should be addressed, since standing water shortens the life of most coatings. Regular inspection and an eventual recoat keep the roof protected.
Local help
Roof Coating Near Me
In Maplewood, the roofs that get coated are mostly low-slope membranes and metal panels, not shingle roofs. From Maplewood out to neighboring communities such as Vauxhall, Union, Springfield and Short Hills, coatings help weathered metal and rubber roofs on homes, barns and garages, but only when the roof underneath is sound.

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. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Maplewood is busiest after a hard winter and before the next one.

Common questions about roof coating
What weather is needed to apply a roof coating?
Dry weather and moderate temperatures are best for coating a roof. Acrylic can wash off if rain or dew hits it before it cures, and silicone also needs a dry window.
Can you coat an asphalt shingle roof?
Most roofers recommend against it. Shingle roofs are usually better served by repair or replacement.
Will a roof coating fix a leaking roof?
It seals small openings, though the actual leak points still need repairs first. Coating over a wet roof seals the problem in.
When does a coated roof need recoating?
It varies with the coating type, the thickness and the quality of the prep work. When the coating wears, a recoat usually renews it.
What is the difference between silicone and acrylic roof coating?
Silicone is the choice for roofs that hold some water, and acrylic works on roofs that drain quickly. Silicone collects dirt over time and only bonds well to more silicone, which matters when it is time to recoat.
