Silicone roof coating is the product we reach for most on flat commercial roofs in New York, NY. It is moisture-cured, it takes ponding water without softening, and it holds up to UV better than most acrylics. That makes it the usual pick for silicone roof restoration over aged TPO, EPDM, modified bitumen, BUR and spray foam.
The coating is only as good as the prep. Our crew starts with a core cut and a moisture scan, because silicone over wet insulation just traps the problem. Wet boards get cut out and replaced. Then we power wash, prime where the substrate calls for it, and reinforce seams, penetrations and drains with fabric and a heavier pass before the field coat goes down.
One thing owners should know: silicone is hard to recoat with anything but more silicone. Other coatings will not stick to it. That is fine for most buildings, since a future recoat is usually just a clean and another silicone pass. It is worth planning for, though.
Silicone roof coating in New York, NY also turns a dark roof white, which cuts the heat load on the deck below. How much that saves depends on the building, the insulation and the HVAC, so we do not quote a number. If your roof has low spots that hold water for days, read about our ponding water repair first.
