The Smart Alternative to Full Replacement
Your commercial roof is showing its age. Seams are starting to separate, you're patching leaks more frequently, and you're bracing for the cost of a full replacement. But what if you could add 10-15 years to your roof's life for 30-40% of replacement cost?
What Are Roof Coatings?
Roof coatings are liquid-applied membranes that create a seamless, waterproof barrier over your existing roof. Think of it as a protective skin that renews and reinforces your current roofing system.
Types of Roof Coatings
Silicone Coatings
Best for: Flat roofs with ponding water issues
UV resistant and highly reflective
Stays flexible in Texas heat
Won't chalk, crack, or erode from UV exposure
10-20 year warranty available
Acrylic Coatings
Best for: Sloped roofs with good drainage
Most cost-effective option
Excellent reflectivity
Easy to apply and maintain
Not recommended for ponding water areas
Polyurethane Coatings
Best for: High-traffic roofs
Superior impact and puncture resistance
Handles foot traffic from HVAC maintenance
Two-coat system (base + top coat)
Highest performance but highest cost
When Coatings Make Sense
A coating is ideal when:
Your current roof is structurally sound but aging
You have 5+ years of useful life remaining in the substrate
You want to avoid the disruption of tear-off and replacement
Budget constraints make full replacement impractical
You want to improve energy efficiency
A coating is NOT ideal when:
The roof deck is compromised
More than 25% of the membrane has failed
Insulation is wet or damaged
The roof has significant structural issues
Energy Savings
In the DFW climate, a reflective roof coating can reduce rooftop temperatures by 50-60°F. For a typical 20,000 sq ft commercial building, this translates to:
15-25% reduction in cooling costs
Potential utility rebates
Reduced HVAC wear and maintenance
Improved tenant comfort
Our Coating Process
**Assessment** — We inspect the existing roof and test for moisture in the substrate
**Preparation** — The roof is power-washed and all repairs are made
**Priming** — Appropriate primer is applied to ensure adhesion
**Application** — The coating is spray-applied in multiple passes to ensure uniform thickness
**Inspection** — We verify coverage, thickness, and adhesion
**Warranty** — NDL (No Dollar Limit) warranties available up to 20 years
