If your commercial building in St. George has an aging flat or low-slope roof, you don’t automatically need a full tear-off. A silicone roof coating can restore your existing roof, stop leaks, and reflect Southern Utah’s intense heat — often for a fraction of the cost of a replacement. Here’s what commercial building owners should know about pricing.
What drives the cost of a commercial roof coating?
Roof coatings are typically priced per square (100 square feet). A few factors move the number:
- Roof size and access. Larger roofs cost more overall but often less per square. Height and difficult access (multi-story, limited staging) add labor.
- Coating system and warranty. A thicker application with a longer manufacturer warranty (10, 15, or 20 years) uses more material and costs more up front — but extends the life of your roof.
- Roof condition and prep. Repairs to seams, flashings, ponding areas, and damaged panels are completed before coating. A clean, sound surface is what makes the coating bond and last.
- Add-ons. Skylight replacement, HVAC panel work, and drainage correction are quoted separately.
Coating vs. full replacement
A restoration coating seals your current roof and adds years of protection without the disruption, debris, and cost of a tear-off. For many Southern Utah buildings it’s the more cost-effective path — and the reflective, “cool roof” surface can lower cooling bills through the desert summer.
