Roof survey
A check for wet insulation or decking so the coating is not sealing in a problem.

Roof Coating Closter, NJ
A Closter roofing contractor can coat an aging membrane or metal roof to seal small cracks and seams and reflect heat, once the surface is cleaned and repaired, and a moisture check comes first, because coating over wet insulation traps the problem. Dial (551) 395-0646 to talk with a local roofer about a coating.
Roof coatings are rolled or sprayed on as a liquid and cure into a continuous, flexible skin. It seals hairline cracks, covers seams and fasteners and protects the roof underneath from sun, which is what breaks most roofing down over time. Light-colored coatings also reflect heat, which can keep the space under a low-slope roof noticeably cooler.
Coatings work best on low-slope and metal roofs, not on most asphalt shingle roofs. They bond to EPDM, TPO, mod bit, built-up gravel-free roofs, spray foam and metal when the surface is prepared and primed correctly. On shingle roofs, coatings are generally avoided because they can hold moisture and interfere with how shingles shed water.
The biggest mistake is coating a roof that is wet inside. If insulation or decking below the membrane is soaked, the coating seals the moisture in and the roof keeps deteriorating out of sight. A moisture survey, using a meter, infrared scan or core cuts, should come before any coating plan.
Depending on what the roofer finds, roof coating in Closter, NJ can go hand in hand with flat roof repair and metal roof coating.

How roof coating works
Most of a coating job is preparation, not spraying.
Test the roof
A moisture survey finds any wet insulation or decking before a coating is considered. Any soaked areas must be removed and replaced first.
Surface prep
A thorough wash strips away dirt, algae and chalky residue. Metal roofs get rust treated, and some membranes need a specific cleaner.
Repair the roof
Open seams, blisters, splits and failed flashing are repaired, and exposed fasteners on metal are tightened or replaced with oversized screws. A coating hides the surface, so anything left unrepaired stays hidden.
Apply primer
A primer or bonding coat goes on where the coating maker requires it. Adhesion problems are hard to fix later.
Apply the coating
The crew builds up the coating to the specified thickness, measured in mils, across the whole roof. Rain or dew before curing can wash out acrylic, so timing is important.
What is included
Parts of a roof coating
Finish coat
Silicone, acrylic or another coating applied to the specified thickness for a continuous, reflective surface.
Cleaning
A full wash and removal of loose material which decides how long it lasts.
Seam repair
Seams, blisters, punctures, flashing and fasteners repaired before the coating goes on.

Roof Restoration Closter, NJ
Where a coating adds a protective layer, roof restoration includes all the repairs needed to make the existing roof sound again. It usually means a moisture survey, replacing wet sections, rebuilding failed seams and flashing, reinforcing weak spots and then coating the entire roof. It is a way to extend roof life while keeping the old roof out of the landfill.
The window for restoration closes once the roof is wet throughout. 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 Closter, NJ
Flat roof coating is the most common use of roof coatings, since low-slope roofs face the most sun and standing water. Silicone handles ponding water well and stays flexible, acrylic is reflective and easy to recoat but should not sit under standing water, and polyurethane is tough against foot traffic and impact. The roofer picks a coating that bonds to your specific membrane.
A coating is not a cure for poor drainage. Clogged drains, blocked scuppers and low spots that hold water for days should be addressed, since standing water shortens the life of most coatings. An annual look, especially at seams and drains, helps catch wear early.

How the weather here affects roofs around Closter
Cold winters bring snow, ice and a long stretch of freezing nights. 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 Closter, NJ have the roof checked in the fall and again after the snow melts.

Common questions about roof coating
Will a roof coating fix a leaking roof?
Coatings help with minor leaks once the damaged areas are fixed, but they are not a patch for a failing roof. 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 holds up to ponding water and stays flexible, while acrylic is reflective and easy to recoat but needs a roof that drains well. Silicone collects dirt over time and only bonds well to more silicone, which matters when it is time to recoat.
What weather is needed to apply a roof coating?
Most coatings need a dry surface and mild temperatures to cure. Rain or heavy dew before curing can ruin a fresh coat, especially acrylic.
Should asphalt shingles be coated?
Coating shingles is generally not recommended. A coating can trap moisture under shingles and may conflict with the shingle maker's terms.
