Commercial and Industrial Reroofing

The commercial roofing experts at Emmons Roof Service specialize in re-roofing. We work in a wide variety of industries with specialized roofing and equipment needs, including retail, food processing, hospitals (OSPD) and education.

As a commercial roofing specialist, we will provide roof reports, estimates, and budget figures prior to signing a contract. We offer many types of energy efficient roof systems or coatings to suit your building’s specific roofing needs and condition.

We offer full roof removals, structural upgrades, as well as plywood/metal deck replacement prior to installing a new roof system. Types of roofing systems applied are PVC and TPO single-ply membrane systems, built up roof systems and torch (APP) applied membrane systems. Various types of insulation with R-Values from R-6 to R-40 can be incorporated into the re-roof options we offer. Systems are Class A & FM approved where applicable and comply with Title 24 (California Cool Roofing).

Sheet metal flashings, copings, and waterproofing are offered as well, making the roof project a turnkey operation, eliminating additional sub-contractors and owner involvement.

We provide all building permits, licenses and our warranties range from two to 25 years. Prorated and “No Dollar Limit” warranties are also offered.
