Amarillo headquarters: complete commercial roof rebuild
Core Commercial Roofing completed a significant re-roof for a government agency at its Amarillo District Headquarters. The failed gravel-surfaced built-up roof over a structural concrete deck was replaced with a multi-layer, fully adhered TPO system: polyurethane foam adhesive attachment, flat polyiso, a full tapered insulation plan, a DensDeck cover board, and a new membrane engineered to fix long-standing ponding.

Before and during the work
What the project involved
- +Removal of gravel-surfaced built-up roof over concrete
- +Two-part polyurethane foam adhesive attachment (no deck fasteners)
- +3.4 inches of flat polyiso base insulation
- +Full tapered polyiso system for positive drainage
- +Half-inch DensDeck cover board
- +Fully adhered TPO membrane
How we approached it
The original built-up asphalt roof with gravel had exceeded its service life on a structural concrete deck. Ponding came from a lack of positive drainage. Fasteners were not an option through the concrete, so every layer had to be adhered.
We secured each insulation layer with two-part polyurethane foam adhesive, installed flat polyiso, then a full tapered system to re-slope the roof. A DensDeck cover board supported the fully adhered TPO membrane and added impact and fire resistance for a long-term drainage fix.
