Rooftop Ductwork Silicone Coating.
A silicone coating over your rooftop ductwork reflects New Mexico's brutal sun, seals every seam, and cuts the heat your AC has to fight all summer.

Overview
In New Mexico, rooftop HVAC ducts sit in full sun all day — metal that bakes hot enough to curl the paint off a car. That heat soaks into the cooled air moving through the ducts before it ever reaches a vent inside, so your air conditioner has to work harder to keep up. It's one of the most overlooked energy losses on a flat-roof building.
A silicone coating fixes both problems at once. It wraps every duct in a seamless, reflective skin that bounces the sun's heat instead of soaking it up, and it seals the seams and joints where cooled air quietly leaks out. It works on your existing ducts with no tear-out and no replacement, and it shields the metal from the sun and the constant heating-and-cooling that slowly destroys bare ductwork.
Part of a roof replacement
This is usually one piece of a larger project. We fold it into your residential roof replacement or commercial roofing so it’s scoped, scheduled, and warrantied as one job.
What’s involved
Clean and prep
We clean the ducts of dust, rust, and loose material so the silicone bonds to solid metal. Any rust is treated before we coat — sealing rust in place only puts off the problem.
Seal seams and joints
Seams, end caps, branch connections, and any place where sections meet are sealed with matching tape or sealant before the coating goes on. These are the spots where both heat and air get in or out.
Silicone base and top coat
We apply a reflective silicone coating in a base coat and a top coat over the whole duct, building a seamless skin. The finished coat is bright white, so it reflects the sun's heat instead of letting the duct soak it up.
Where ducts pass through and connect
Where ducts pass through curbs, connect to rooftop units, or turn a corner, we seal those spots separately to keep the coating unbroken and the seal complete.
