Pricing and What Drives It
Quoted project total: $106,995. The primary cost driver for this project was the size of the roof, with pressure washing, repair, and a two-coat silicone application across the full 28,800 sq ft.
Typical published range for this project type: $90,000+.
The Situation
The property manager contacted Five Guys Roofing to proactively coat the existing TPO roof, which was still in relatively good condition but due for added protection.
- The roof was still relatively young but the ownership group wanted to extend its service life
- No urgent leak, but proactive protection was the priority
- A large single-building roof needing full coverage
What Was Causing It
The identified cause was the ownership group’s decision to proactively protect a TPO roof before it aged into needing more significant repairs.
How We Verified the Roof Condition
Our team verified the roof’s condition and prepared it for coating: cleaning the surface, repairing any damaged areas, and sealing every penetration before any coating went down.
- Sprayed a wash treatment over the existing roof system
- Pressure washed and cleaned the existing roof, removing dirt and debris buildup
- Made needed repairs to the roof system, including blisters, splitting, and seam repairs
- Applied silicone mastic around all roof penetrations, drains, scuppers, skylight curbs, and AC curbs
The Plan
The scope for this project called for a full wash-and-recoat: clean and repair the existing TPO roof, then apply a two-coat white silicone coating system across the entire 28,800 sq ft roof.
Materials and Components Used
- Wash treatment: Tropical #652 roof wash treatment
- Detail work: Tropical silicone mastic #9400 for penetration and detail work
- Coating: Tropical #924 white silicone roof coating, applied at 2 gallons per 100 sq ft
- Seal/finish: Chemlink caulking for parapet wall cap metal and termination flashing joints
Step-by-Step Work
Cleaning and Prep
We sprayed a wash treatment over the existing roof, then pressure washed and cleaned the full surface to remove dirt and debris buildup, hauling away job-related debris.
Repair and Detail Work
We made needed repairs to the roof system, including blisters, splitting, and seam repairs, then applied silicone mastic around all roof penetrations, drains, scuppers, skylight curbs, and AC curbs.
Coating and Final Walk
We applied a white silicone roof coating at 2 gallons per 100 sq ft across the full roof, detailing carefully around every penetration and up the parapet walls. We reinstalled roof drain covers, applied fresh caulking to parapet wall joints, and cleaned the work area. A project manager returned for a final quality check, confirming the roof looked great with no touch-ups needed.
Results
After completion, the building had a fully restored roof surface: a cleaned and repaired TPO membrane covered by a new white silicone coating system.
The property received a 15-year workmanship warranty from Five Guys Roofing, plus a 15-year manufacturer warranty on the coating.
