Our commercial roofing options


Pitched roofs with slopes 3/12 or greater have many laminated options including lifetime, 50 year, high impact slate look, and cool technologies

Low slope

Roofs pitched less than 3/12 can experience lasting protection with EPDM (rubber), Self-adhered modified bitumen, and membrane options such as TPO with welded seams instead of glue seams.

Metal roofs

Metal provides superior protection and durability available in standing seam and granulated "shake" style.

Roof Coatings

Coating significantly extends the life of many roofs with the added benefit of lesser costs as well as exceptional tax advantages. Coatings can be installed on metal as well as roof membranes including EPDM (rubber) and seam welded systems.
