Pricing and What Drives It
Quoted project total: $60,555. The primary cost driver for this project was the size of the roof, with washing, repair, and a two-coat elastomeric application across 20,565 sq ft.
Typical published range for this project type: $50,000+.
The Situation
The property manager contacted Five Guys Roofing to proactively recoat the existing built-up roof before it aged into needing more significant repairs.
- The existing roof coating had aged and was due for renewal
- No urgent leak, but proactive protection was the priority
- The building remained tenant-occupied throughout the project
What Was Causing It
The identified cause was the age of the existing built-up roof system, which was due for a proactive recoat.
How We Verified the Roof Condition
Our team verified the roof’s condition and prepared it for recoating: removing old equipment and debris, cleaning the surface, and sealing every penetration before any coating went down.
- Removed debris and old equipment from the roof
- Pressure washed and cleaned the existing roof system, removing dirt and debris buildup
- Cut out and repaired large ridging areas using a 5-course repair method
- Applied fibered mastic sealant and reinforced fabric around all roof pipes, vents, cracks, and other penetrations
The Plan
The scope for this project called for a wash-and-recoat restoration: clean and repair the existing built-up roof, then apply a two-coat white elastomeric coating system across the full 20,565 sq ft.
Materials and Components Used
- Primer: water-based primer, applied as needed
- Coating: Soprema #901 white elastomeric coating, base coat and top coat, each at 1.5 gallons per 100 sq ft
- Drain detailing: 40-inch tytec membrane around all roof drains
- Seal/finish: Chemlink caulking for parapet wall flashings and joints
Step-by-Step Work
Removal and Cleaning
We removed debris and old equipment from the roof, then pressure washed and cleaned the existing roof system, hauling away job-related debris.
Repair and Detail Work
We cut out and repaired large ridging areas using a 5-course repair method with tytec and high-solid sealant, then applied fibered mastic sealant and reinforced fabric around all roof pipes, vents, cracks, tears, and other penetrations. We installed tytec membrane around every roof drain and resecured loose fasteners in the parapet coping metal.
Coating and Final Walk
Once the roof was dry, we applied a water-based primer as needed, then a base coat and top coat of white elastomeric coating at 1.5 gallons per 100 sq ft each, detailing carefully around every penetration, rooftop equipment, and AC unit. We reinstalled roof drain covers, applied fresh caulking to parapet wall joints, and cleaned the work area before a final walkthrough.
Results
After completion, the building had a renewed roof surface: a cleaned and repaired built-up roof covered by a fresh, uniform white elastomeric coating.
The property received a 10-year warranty from Five Guys Roofing, covering workmanship and manufacturer materials, transferable, including free yearly inspections.
