Commercial Roof Coating & Restoration in Gilbert, AZ

Commercial Roof Coating and Restoration in Gilbert, AZ

Roof coating is one of the most cost-effective tools in commercial roofing, and it's underused. A properly applied coating system on a roof that still has structural integrity can add 10–15 years to the roof's service life at roughly one-third the cost of a full replacement. In Arizona, the energy savings from a highly reflective white coating can generate meaningful ROI on top of the avoided replacement cost.

Is Your Roof a Coating Candidate?

Not every roof can be coated. Coating over a wet, deteriorated, or structurally compromised membrane just seals problems in. The assessment criteria:

• Less than 25% of insulation is wet (verified by infrared or core samples)
• The membrane is still adhered — no widespread delamination or tent-like sections
• Seams and flashings can be reinforced prior to coating
• The deck is structurally sound

If your roof passes those criteria, coating is worth serious consideration. We'll tell you honestly if it doesn't.

Coating Types

Silicone Coatings

Silicone is the most durable coating for Arizona conditions. It doesn't chalk or erode in UV the way acrylics do, it's highly flexible, and it tolerates ponding water without degrading — a significant advantage. Silicone can be recoated when it eventually thins, extending the system indefinitely. The downside: silicone is slippery when wet and doesn't allow recoating with other product types.

Acrylic Coatings

Water-based acrylic coatings are the most economical option. They apply easily, clean up with water, and provide excellent reflectivity when first applied. The limitation in Arizona is that acrylics erode more quickly under UV and don't tolerate ponding water well. On a roof with good drainage and UV exposure, acrylics can be a good solution. On a roof with ponding areas, silicone is the better choice.

Polyurethane Coatings

Aliphatic polyurethane coatings offer excellent abrasion resistance and UV stability. They're used on roofs with heavy foot traffic or as topcoats over base coats. More expensive than acrylics but more durable in high-wear areas.

The Coating Process

Coating isn't just rolling product on. Proper preparation is 80% of the job. We pressure-wash the entire surface, repair all open seams and flashings with reinforcing fabric and coating, seal all penetrations, and allow everything to cure before applying the base coat and finish coat. A rushed or poorly prepped coating job peels within a season.
