This large commercial warehouse has an office wing with its own roof and a parapet wall around the main roof. The main roof was TPO, and the office roof was covered in rock. Troyer Commercial Roofing got the signed go-ahead in May 2025. Materials showed up in June, and the last of the roof was done in September 2025.
What was the original plan for this warehouse roof?
Tear the old TPO off the whole main roof and spray a new closed-cell foam roof in its place. That was the plan Lester Troyer, roofing since 2007, priced for this warehouse.
Why did the plan change partway through the job?
Rain. The summer rainy season set in, and it rained almost every day on this warehouse job. The Troyer Commercial Roofing crew tore off and foamed the east section and foamed the office roof, but with rain nearly every day, tearing off and foaming the rest of the main roof was no longer workable. Lester called the owner, and together they agreed to change course on the west and center sections.
That kind of call is what Lester is known for. When a job stops going to plan, he sees another way through it and can change course on a dime, without cutting corners on the roof and while still giving the building owner the same warranty.
Can you coat an existing TPO roof instead of tearing it off?
You can. Troyer Commercial Roofing left the existing TPO in place on this warehouse’s west and center sections, pressure washed it with Wac II cleaner, applied a tack coat, and installed a full fabric reinforced membrane system over it. No foam went on those sections. Every roof area, coated TPO and foam alike, was finished with a white PUMA XL top coat.
How was each section of the warehouse roof handled?
East section of the main roof:
- Removed the TPO and hauled it away
- Installed new poly iso board where needed
- Added plates and screws
- Taped the seams and applied Prime Time primer
- Sprayed 2.8 pound closed-cell spray polyurethane foam, about 1.5 inches thick
- Rolled in Benchmark base coat
- Sealed off every protrusion
Office roof:
- Removed the rock and hauled it away
- Pressure washed the roof
- Applied spray polyurethane foam
West and center sections of the main roof:
- Pressure washed the existing TPO with Wac II cleaner
- Applied a tack coat
- Installed a full fabric reinforced membrane system
Every roof area:
- Finished with a white PUMA XL top coat
Finished, the warehouse roof rates 85 percent reflectivity and UL 790 Class A for fire.
What warranty covers the warehouse roof?
This commercial warehouse roof is warranted against leaks for 20 years. The warranty covers materials and workmanship.
Who makes the call when a roofing job has to change?
On this warehouse, Lester made it together with the owner when the rain set in, and the building still got a finished white roof over every section. Tony walks every roof with Lester.
