Pricing and What Drives It
Quoted project total: $346,750. The primary cost driver for this project was the size of the roof and the extent of coating and detail work required across a large occupied office building.
Project documentation included the signed proposal and a workmanship warranty certificate.
The Situation
The property manager contacted Five Guys Roofing about an aging EPDM roof membrane that was nearing the end of its service life, ahead of any active leaks.
- EPDM membrane showing its age after years in service
- No urgent leak, but the roof was due for renewal
- A large, occupied building where coordination mattered
What Was Causing It
The identified cause was the age of the existing EPDM membrane.
How We Verified the Roof Condition
Our Five Guys Roofing team verified the roof’s condition and prepped it for coating: cleaning the full membrane, treating every seam and penetration, and confirming the surface was ready before any coating went down.
- Pressure washed and cleaned the entire existing EPDM roof to remove dirt and debris buildup
- Applied seam sealer around all roof penetrations, drains, scuppers, skylight curbs, and AC curbs
- Detailed ponding-water locations and other seams before coating
- Coordinated access and work areas with the property’s tenants throughout
Supporting documentation included the signed proposal and a workmanship warranty certificate.
The Plan
The Five Guys Roofing scope for this job called for a full seal-coat restoration over the existing EPDM membrane: clean and prep the roof, seal every seam and penetration, then apply a silicone coating system across the full 180,000-square-foot roof.
Materials and Components Used
- Cleaner: Gaco Wash roof cleaner
- Seams and penetrations: Gaco seam sealer
- Coating: Gaco S4200 white silicone roof coating, applied at 1.25 gallons per 100 sq ft
- Reinforcement: 6-inch seam tape
- Drainage: existing roof drain covers, reinstalled
Step-by-Step Work
Cleaning and Prep
We pressure washed and cleaned the entire existing EPDM roof, removing dirt and debris buildup and hauling away job-related debris to leave a clean surface for coating.
Seam Sealing and Detail Work
We applied seam sealer around all roof penetrations, drains, scuppers, skylight curbs, AC curbs, seams in ponding-water locations, and other rooftop penetrations, then detailed up the parapet walls.
Coating, Cleanup, and Final Walk
We applied the white silicone roof coating across the full membrane, reinstalled the existing roof drain covers, and cleaned the work area, hauling away all trash and debris before handoff. Final photos were sent to the property manager once work was confirmed complete.
Results
After completion, the building had a fully restored roof surface: a cleaned and sealed EPDM membrane covered by a new silicone coating system designed to extend the roof’s service life.
The property received a 10-year workmanship warranty from Five Guys Roofing, plus a 50-year limited manufacturer warranty on the coating material.
