Flat Roof Coatings
Extend the life of your existing flat roof by 10-20 years without a full replacement. Roof coatings create a seamless, reflective barrier that waterproofs, insulates, and protects your investment.
Restore Instead of Replace
A full commercial roof replacement is expensive and disruptive. For roofs that are aging but still structurally sound, a coating system can add 10-20 years of waterproof protection at a fraction of the cost — and with zero disruption to the business below.
The Cool Roof Advantage
In the High Desert, a dark flat roof can reach surface temperatures of 170°F or more on a summer day. A white reflective coating brings that down to 100-110°F — dramatically reducing the heat load on your HVAC system and lowering energy costs immediately.
Seamless Protection
Unlike roofing systems with seams, joints, or overlaps, a liquid-applied coating creates a completely seamless membrane. There are no seams to fail, no fasteners to back out, and no joints to separate. The entire roof becomes a single, continuous waterproof barrier.
Choosing the Right Coating
The best coating depends on your roof’s current condition and drainage characteristics. Silicone is best for roofs with ponding water, acrylic works well on sloped surfaces with good drainage, and elastomeric coatings are ideal for older substrates that need crack-bridging capability. We evaluate your specific situation and recommend the right system.
How We Install Flat Roof Coatings
Roof Inspection
We thoroughly inspect the existing roof for damage, moisture, and adhesion issues. Core samples may be taken to assess the substrate.
Surface Preparation
The existing roof is power-washed, repaired, and primed. All seams, penetrations, and damaged areas are reinforced with fabric.
Coating Application
Multiple coats of coating are spray-applied or rolled on to the specified thickness, creating a seamless waterproof membrane.
Inspection & Warranty
Final thickness measurements and adhesion tests verify the system meets warranty requirements. Most systems carry 10-20 year warranties.
Advantages & Considerations
Advantages
- Lowest cost option — fraction of full replacement
- No tear-off required — apply directly over existing roof
- Seamless application — no seams means no leak points
- Highly reflective — dramatic energy savings
- Extends existing roof life by 10-20 years
Considerations
- Not suitable for roofs with extensive damage or wet insulation
- Requires periodic recoating (every 10-15 years)
- Application is weather-dependent
- Not a structural repair — underlying issues must be fixed first
What Makes Flat Roof Coatings Stand Out
Silicone Coatings
The premium choice for ponding water resistance. Silicone doesn't break down in standing water and provides excellent UV protection in desert conditions.
Acrylic Coatings
A cost-effective option for roofs with good drainage. Acrylic coatings are highly reflective and easy to apply, but require proper drainage to perform.
Elastomeric Coatings
Flexible rubber-like coatings that bridge cracks and accommodate building movement — ideal for older buildings with minor structural shifting.
Cool Roof Performance
White roof coatings reflect up to 85% of solar radiation, meeting and exceeding California Title 24 cool roof requirements.

Common Questions About Flat Roof Coatings
Can any flat roof be coated?
Most flat roofs can be coated if the existing membrane and insulation are in reasonable condition. Roofs with extensive damage, wet insulation, or structural issues should be replaced rather than coated.
How much money can a roof coating save?
Building owners typically see cooling cost reductions of 15-30% after installing a reflective roof coating. Combined with the cost savings versus full replacement, the ROI is significant.
