Restaurant roofs present a couple of unique problems that Commonwealth Roofing specializes in solving. First, restaurants usually have a large number of rooftop units for kitchen vents, cooler compressors, and air conditioners. 
This means that there are a lot of flashing details for curbs, vents, and pitch pockets, and these are the most common source of problems on any flat roof.
Second (and most important), those kitchen vents expel animal fats which always end up on the roof as a greasy mess. Worse than the mess, though, is the fact that all but one commonly-used roofing material are eaten away by animal fats. Built-up, modified asphalt, EPDM (rubber), TPO, and polyurethane foam (PUF) are all seriously compromised by this grease. Only PVC is inherently resistant to animal fats.
Fortunately, Commonwealth Roofing is a Master Elite Contractor for Duro-Last PVC Roofing. Duro-Last solves the first problem with restaurant roofing by prefabricating the roof system to fit the building and each curb and vent penetration. These factory pre-made flashings provide more dependability than field fabricated flashings, so these critical details remain 
trouble free for years. Second, because Duro-Last is PVC, it is resistant to the animal fats that are ever-present with restaurant roofing.
Restaurant roofing can also involve other types of roof, including metal, shingles, tile, and slate. Whatever is needed, call or email “The Roofers” at Commonwealth Roofing for the best solutions to restaurant roof problems.
