Replacing a commercial roof is a major capital expense that disrupts your day-to-day operations. A professional commercial flat roof restoration applies a seamless, high-performance liquid membrane directly over your existing roof. This stops leaks, extends your roof’s lifespan by 10 to 20 years, and eliminates the massive labor, landfill, and material costs of a premature tear-off.
Not all roofs are restored the same way, but most major commercial flat roof styles are excellent candidates for a silicone or acrylic restoration coating system.
TPO (Thermoplastic Polyolefin): Restoring prevents the common issue of seam degradation and cracking caused by prolonged UV exposure. It requires a specific primer to ensure the coating bonds seamlessly to the slick thermoplastic surface.
EPDM (Rubber): Over time, rubber roofs shrink and seams pull apart. Coating wraps the entire roof in a monolithic layer, sealing vulnerable flashings and black rubber surfaces to massively reduce heat absorption.
PVC (Polyvinyl Chloride): Older PVC membranes lose their plasticizers and become brittle. A restoration coating adds a flexible, highly reflective shield that halts this aging process.
Excellent. It is chemically hydrophobic and will not degrade or wash away under standing water.
Poor. Waterborne acrylics will re-emulsify (break down) if subjected to standing water for extended periods.
High. Maintains its color and flexibility for decades without chalking or thinning under intense UV rays.
Very High initially. Excellent initial reflectivity, but tends to degrade faster than silicone, requiring thicker initial coats or re-coating sooner.
Low-slope roofs with drainage issues or dead valleys where water collects for more than 48 hours.
Well-sloped roofs with positive drainage in high-UV, low-moisture regions.
Higher material cost up front, but longer lifecycle and lower maintenance.
More budget-friendly initial material cost, but requires stricter application conditions and more frequent maintenance.
Yes, absolutely. In fact, stopping existing leaks is one of the primary reasons to restore a roof. However, the process requires sealing those active leaks, reinforcing the seams, and replacing any wet insulation before the final coating is applied. Coating over trapped moisture will cause the system to fail.
On average, a commercial flat roof restoration costs 50% to 70% less than a full tear-off and replacement. Because the crew applies the coating directly over your existing substrate, you completely eliminate the heavy labor costs of tear-off, landfill disposal fees, and the cost of buying entirely new insulation boards.
A professionally installed fluid-applied restoration system typically extends the life of your roof by 10 to 20 years, depending on the thickness of the coating applied. Best of all, many high-quality silicone systems can be cleaned and re-coated at the end of their warranty period, essentially resetting the clock for another decade or two.
Unlike a roof replacement, which must be capitalized and depreciated over 39 years, a roof restoration is generally classified as a maintenance repair expense. This means you can often deduct the entire cost of the project in the single tax year the work is completed, providing a major immediate tax advantage.
Minimally, if at all. A full roof tear-off is incredibly noisy, messy, and creates open liabilities over your inventory or tenants. Restoration uses fluid-applied systems that generate almost no structural noise, require no heavy tearing machinery, and emit low odors, allowing your business to remain fully open and operational throughout the application.
The Golden Rule of Coatings: If your flat roof experiences “ponding water”—areas where water sits for more than 48 hours after a rainstorm—silicone is mandatory. Acrylic coatings will soften and fail under standing water.
You cannot coat over a failed, water-logged roof structure. Before moving forward with any restoration project, it is vital to pinpoint exactly where moisture is hiding beneath the membrane.
