What Roof Coating Involves

A roof coating is a thick, liquid-applied membrane that cures in place to form a seamless, waterproof layer over your existing roof. Unlike a tear-off and replacement, this service works with your current system — whether that's TPO, EPDM, metal, or built-up asphalt — as long as the substrate is sound and properly prepared.

The two main chemistries are silicone and acrylic elastomerics. Silicone coatings excel at ponding water resistance, making them ideal for Dallas roofs with flat or low-slope areas that don't drain perfectly. Acrylics are more economical and offer excellent UV reflectivity, but they require a dry surface and good drainage. Polyurethane systems are used where physical impact or foot traffic is a concern, such as around HVAC units. A primer system is almost always required to ensure adhesion, especially on aged membranes or metal panels.

Application begins with pressure washing to remove dirt, debris, and biological growth. Then we hand-seal all seams, flashings, and fasteners with a compatible caulk or tape. The coating is applied by spray or roller in two coats, with a minimum dry film thickness specified by the manufacturer. Cure time depends on humidity and temperature — in Dallas summer heat, most systems cure in 24–48 hours.

Signs You Need Roof Coating

You need this service when your roof is structurally sound but showing end-of-life wear. Look for ponding water that remains 48 hours after rain — that's a sign your membrane is losing its slope or the surface has become too rough to shed water. Membrane seam separation, where the factory seams are lifting or curling, is another red flag. Blistering or alligatoring on built-up roofs indicates the surface is degrading from UV exposure. Flashing pull-away at the parapet lets water wick behind the membrane. Interior staining at column lines or around roof penetrations means water is already finding a path in.

If you're seeing any of these, a coating can restore the roof's integrity — but only if the underlying insulation and deck are dry. We verify this with moisture meters and, when needed, infrared scans before recommending a coating.

Our Roof Coating Process

Our process starts with a roof asset survey. We walk the entire roof, document existing conditions, and take photos of every penetration, seam, and flashing detail. Next is a specification review — we match the coating system to your roof type, your budget, and your energy-efficiency goals. We then prepare the surface: pressure wash, scrape loose material, and prime any bare metal or aged membrane. Seams and flashings are hand-sealed. The coating is applied in two coats, with a minimum thickness verified by wet film gauge. Finally, we do a full walk-through with you, documenting the completed work and providing manufacturer warranty enrollment paperwork.

For occupied buildings, we coordinate with your tenants — we can schedule work after hours or in phases to minimize disruption.

Cost Considerations in Dallas

Roof coating costs in Dallas typically range from $2.50 to $5.50 per square foot for silicone systems, and $1.80 to $3.50 per square foot for acrylics. Polyurethane systems run higher, around $4.00 to $6.00 per square foot. The final cost depends on roof size, condition, number of penetrations, and whether any repairs are needed before coating. For a 10,000-square-foot roof, that's roughly $25,000–$55,000 — a fraction of the $150,000+ a full replacement would run. Most coating systems pay for themselves in energy savings within 5–7 years, especially with Dallas summer heat driving cooling costs.

Warranty & Insurance

Manufacturer warranties for roof coatings typically run 10–20 years for silicone systems, with NDL (No Dollar Limit) coverage available on some products. Acrylics usually carry 10–15 year warranties. We handle all warranty registration with the manufacturer — you get a transferable warranty that can add value to your building. For insurance, if your roof has storm damage, a coating can be a repair option that your carrier may approve as part of a claim. We document before-and-after conditions and work with your adjuster to ensure coverage.

Signs You Need Roof Coating

⚠

Ponding Water

Water that sits on your roof for more than 48 hours after rain is a sign that the membrane is no longer shedding water effectively. Over time, this leads to membrane degradation and leaks.

⚠

Seam Separation

Factory seams that are lifting or curling allow water to wick into the substrate. A coating system can seal these seams and restore the roof's integrity.

⚠

Blistering or Alligatoring

Blisters and alligatoring on the surface indicate UV degradation of the membrane. This is common on older built-up roofs in Dallas's intense sun.

⚠

Flashing Pull-Away

When flashing pulls away from the parapet, water can seep behind the membrane and cause rot and decay. A coating system can re-seal these areas.

⚠

Ballast Displacement

Loose or displaced ballast on a membrane roof exposes the membrane to UV and physical damage. Coating over the ballast is not an option, but a coating system can be applied after ballast removal.

⚠

Interior Staining

Stains on the ceiling or walls at column lines are a sign that water is already penetrating the roof. A coating system can stop the leak, but only if the substrate is dry and sound.
