Roof coating in Gainesville, FL

What a roof coating actually does

A coating is a fluid-applied membrane that bonds to the existing roof surface. Depending on the product, it:

• Reflects solar heat, lowering surface temperature and reducing cooling load in the building below.
• Seals minor surface checking, pinholes and hairline cracks.
• Restores UV protection to a membrane that has chalked or aged.
• Extends service life by five to ten years when applied to a sound roof.
• Avoids tear-off, keeping old material out of the landfill and avoiding disruption to the building.

It does not fix wet insulation, structural deflection, active leaks or a membrane at the end of its life. Those need repair or replacement first.

Is your roof a candidate?

A coating is worth considering when:

• The membrane is intact and well adhered, with no wide-open seams or blisters.
• Insulation is dry — confirmed by moisture readings, not assumption.
• Drainage is adequate and ponding is limited.
• Leaks are not active and there is no history of repeated interior damage.
• The roof has at least a few years of structural life left.

It is not a good candidate when there is wet insulation, widespread blistering, structural movement, or a membrane so deteriorated that the coating has nothing to bond to. In those cases a coating is a delay tactic, and we will say so.

Coating systems we apply

Acrylic coatings

Reflective, breathable and economical. Good for roofs that need UV protection and heat reduction, and where some moisture vapor needs to escape. Requires a sound substrate and proper priming.

Silicone coatings

Excellent water resistance and ponding tolerance, with good UV stability. Often used on low-slope roofs with standing water. More expensive, and can be slippery when wet.

Elastomeric and polyurethane coatings

Flexible, durable and able to bridge minor movement. Used where thermal movement and foot traffic are concerns.

Product selection depends on the existing membrane, the substrate, drainage and the building's use. We specify the system after inspection, not before.

The coating process

1. Inspection and moisture assessment of the membrane, seams, flashings and insulation.
2. Repairs first: seams, blisters, penetrations and edge metal are addressed before coating.
3. Cleaning and preparation: pressure washing, degreasing and priming so the coating bonds.
4. Detail work: reinforcement at seams, curbs, drains and penetrations.
5. Application: multiple coats at the manufacturer's specified rate, not a single thin pass.
6. Curing and inspection: a final walkthrough with photos and warranty documentation.

Preparation is most of the job. A coating applied over a dirty or wet roof will fail, regardless of the product.

What roof coating costs

Pricing is per square foot and depends on system, surface condition and preparation:

• Acrylic coating: roughly $2–$4 per square foot.
• Silicone coating: roughly $3–$6 per square foot.
• Repairs and preparation: quoted separately based on what we find.

A 5,000 sq ft roof might fall between $10,000 and $25,000. Compare that with low-slope replacement at $8–$18 per square foot, and the economics become clear — when the roof qualifies.
