"A proper coating adds 10-15 years to a tired roof at a fraction of replacement cost. If the prep is done right."
Silicone, elastomeric, acrylic, and aluminum roof coatings for flat, low-slope, and metal roofs across Brooklyn and Queens. We restore aging TPO, EPDM, modified bitumen, and metal roofs without a full tear-off. Energy Star reflective systems cut cooling bills. Fully adhered, fully warrantied, and applied by trained crews. No peeling in year two. No shortcuts.
Roof coating is a liquid-applied, fully adhered membrane that goes on top of an existing roof. It renews the waterproof layer, seals seams and penetrations, and in the case of reflective white coatings, drops rooftop temperatures by 50-80°F and cuts air conditioning load. Properly prepped and applied, a modern silicone or elastomeric coating lasts 10-20 years.
The math matters. A full flat roof replacement on a Brooklyn rowhouse or small commercial building runs $12-25 per square foot. A roof coating system on a sound but aging roof runs $4-8 per square foot and renews the roof for another 10-15 years. When the roof deck is still solid and the insulation is dry, coating is the right answer, not tear-off.
But coating is only as good as the prep. Pressure wash, repair every blister and split, re set every fastener, mesh reinforce every seam, and prime the substrate to the coating manufacturer's spec. Skip any step and the coating peels in 18 months. MLM Construction Group follows full manufacturer spec on every coating job. That is why we can warranty the work.
⚡ NYC CoolRoofs & Local Law 97
NYC CoolRoofs program and Local Law 97 emissions caps reward reflective (white) roofing. Buildings over 25,000 sq ft face emissions penalties, a Energy Star rated reflective coating is a cheaper way to reduce load. We install CRRC listed products that qualify for compliance credits and utility rebates.
100% silicone: ponding water approved, UV stable, and holds up in Brooklyn rain better than any other coating chemistry. GAF Unisil and Henry 587 Tropi Cool systems. 15-year manufacturer warranty on properly prepped roofs.
Great for sloped membrane and metal roofs in sunny exposures. Stretches and contracts with the substrate, reflective white finish, and very cheaper per square foot. Best for roofs without ponding water.
CRRC listed reflective coatings drop roof temperatures 50-80°F and cut AC load. Qualifies for NYC CoolRoofs, Local Law 97 credits, and Con Edison rebates. We document everything for your incentive application.
Rust converter, fastener re seating, seam mesh reinforcement, and a full silicone or acrylic topcoat. Turns a 20-year old rusted metal roof into a watertight, reflective roof for another 15 years.
Before any coating goes down, every seam gets reinforced with polyester mesh and a second coat of base. Penetrations (vents, pipes, HVAC curbs) get detail coated separately. That is what makes coatings last.
Every coating job starts with full pressure wash to remove dirt, algae, and loose material, then a compatibility primer on the substrate. Prep is 40% of labor on a proper coating job, and 100% of the reason coatings fail.
Hardware store elastomeric rolled over a dirty, wet, or weathered roof with no primer, no seam tape, no mesh. It will look great for 6 months and start peeling in year one. This is the most common coating failure we see, and it is always prep, not the coating itself.
Wash, dry, repair, prime, mesh reinforce seams, base coat, top coat. Each step to manufacturer spec. Correct mil thickness measured with a wet film gauge. Warranty paperwork filed. That is how a coating actually lasts 15 years.
Before any coating job, we do an infrared moisture scan of the roof. If the insulation is wet you cannot coat. You have to cut out wet sections first. Skipping this step traps moisture under the coating and guarantees blistering within 2 summers.
Not every aging roof needs a $40,000 replacement. We inspect, moisture scan, and tell you honestly whether coating is the right call, or whether you need a new roof. Either way, the inspection is free and the advice is straight.
