Roof Coating in Atlanta, GA

A roof coating is a fluid-applied membrane that cures into a continuous, reflective skin over an existing roof surface.

We open with a roof condition survey. We probe decking for rot, check ponding water at the low points, and pull a core sample where insulation looks saturated.

If the substrate is sound, we prime it, reinforce the seams with fabric, and build the film in two or three passes. If it is not sound, we say so and quote roof replacement instead.

Material choice drives price. Acrylic coating suits dry, sunny roofs but will not tolerate standing water for long. Silicone coating handles ponding water and stays flexible, which is why most flat roofs get silicone.

Polyurethane coating offers the highest tensile strength and abrasion resistance where foot traffic is heavy. Coverage rate matters as much as chemistry, since a thin film fails early no matter what you bought.

We install systems from GAF Unisil, Henry, and Tropical Roofing. Primer type, cure time, and dry film thickness go in writing before the first bucket opens. Most jobs run one to three days.

Craftsman bungalows and mid-century ranch homes here usually need steep-slope work instead. Low-slope roofs on newer townhomes and condos are the realistic coating candidates, and acrylic elastomeric coating handles most of them well.

We also coat and inspect built-up roof systems, modified bitumen, TPO, EPDM, and PVC membrane roofs, plus metal panel, standing-seam panel, and corrugated panel surfaces. Steep-slope asphalt shingle, three-tab shingle, architectural shingle, wood shake, cedar shake, slate, clay tile, and concrete tile roofs rarely qualify.

Before coating, we check the drip edge and eave for water running back under the fascia, and the soffit and rake for wind damage. The ridge, ridge cap, and ridge vent get inspected for lifted fasteners and blocked airflow.

The valley, step flashing, counter-flashing, chimney flashing, pipe flashing, and every vent boot and skylight get resealed. Parapet walls, gutters, and downspouts are cleared so water leaves instead of sitting on the surface.

Decking tells the truth. We pull a little plywood or OSB sheathing at a suspect spot and look at the truss, rafter, joist, and ridge beam underneath. Soft wood or a screw backing out changes the recommendation.

Crews work off scaffold and ladder with a safety harness. The truck carries a roofing square, nail gun, air compressor, pry bar, and roofing shovel for cut-out work. A torch comes out for torch-down modified bitumen details, and a dumpster holds the debris.

Inside the building, insulation and ventilation matter as much as the coating. A blocked soffit vent or a seized attic fan pushes hot, humid air against the deck and undoes the waterproofing you just paid for.

Roof shape changes the detailing. A hip, gable, mansard, or gambrel profile has more intersections than a flat deck. A canopy or awning overhang above a door needs its own flashing line, and the verge at a gable end gets a close look for wind damage.

On metal roofs, purlins, battens, and counterbattens carry the panels, so we check them for corrosion before coating anything. In older assemblies we still find tar, pitch, and asphalt over bitumen felt, and any tar paper or roofing felt left in place has to be dry and sound. A failed vapor barrier or ice-and-water shield rules coating out.

Snow guard and anchor points get checked where maintenance crews walk, and coping, chimney, and scupper details are measured against local building code. Where sealant, caulk, or adhesive has failed, we cut the joint out rather than coat over it.

Weatherproofing a roof is not the same as waterproofing it forever. Coating buys time and lowers rooftop temperature. It does not fix a wet attic, and it will not survive a long ice dam at the eave.
