Our commercial roofing experts are experienced in the installation and repair of all industrial and commercial roofing options, including:
- Built-Up Roofing- A built-up roof is composed of three elements: felt , bitumen, and surfacing. The felts are made of glass, organic, or polyester fibers, and serve much the same purposes reinforcing steel in concrete. The felts are necessary as tensile reinforcement to resist the extreme pulling force in the roofing materials. Felts installed in layer fashion also allow more bitumen to be applied to the whole system. Bitumen, either coal-tar of asphalt is the “glue” that holds the felts together. It is also the waterproofing material in the system. The surfacing normally is applied to build-up roofs smooth, gravel, slag, or a mineral-coating cap sheet. Gravel, slag may be embedded into the still-fluid flood coat. Gravel and slag serve as an excellent wearing surface to protect the membrane from mechanical damage. On some systems, a mineral coated cap sheet is applied on top of the plies of felt.
- Modified Bitumen- This system was developed in Europe during the sixties and introduced in the U.S. in the early seventies. The term modified refers to the addition of plastic or rubber-based polymeric binders to asphalt to improve its performance and durability. Modified bitumen is used in multiple layers in what is essentially a “factory assembled” build-up roof. Several coats or laminations of modified bitumen are reinforcing mat, which is often covering with a granule-surface cap sheet, or left smooth for aluminum or white coating to be applied. Modified bitumen roofing exhibits many characteristics of built-up (BUR), yet affords the ease of application of a shingle-ply system. These membranes are resistant to heavy traffic, punctures, and tears.
- Single-Ply EPDM- This thermostat membrane is compounded from rubber-polymer and is often referred to as rubber roofing. Some of the features that contribute to the popularity of EPDM single-ply roofing included long-term durability, including excellent resistance to temperature extremes, sunlight, ozone and moisture, ease, speed, and cleanliness of installation. This lightweight synthetic elastomer material has been used since the early 1970s. Another feature is adaptability. Varied application techniques such as ballasted, fully adhered, and mechanically fastened, allow EPDM roofing systems to be applied to virtually any roof surface: flat, spherical, curved, or slanted.
- Thermoplastics PVC/TPO Single-Ply- Thermoplastic single-ply membranes are revolutionizing the commercial and industrial roofing industry. They represent the fastest growing segment of the U.S. roofing market over the past five years. The PVC product is a reinforced membrane with tough solvent-or-hot-air welded seams. This material has excellent durability and dimensional stability. The TPO product advances the category yet another step by combing the hot-air welding benefits of EPDM, the more traditional single-ply material. Both PVC and TPO are aesthetically pleasing, lightweight, and highly resistant. We are proud to include all of these new and technically advanced roofing systems.
