TPO is the fastest-growing commercial membrane roofing system around and is on the forefront of single-ply roofing technology. It’s engineered for superior, long-term performance and offers the added benefit of being environmentally sound. Those who’ve used and installed it find that its advanced reflectivity dovetails nicely with cool roofing solutions, helping to keep their storage facilities, warehouses, and working environments more cost efficient. Further, TPO offers reduced maintenance and is highly versatile, offering resistance to environmental pollutants and chemicals. And those in stormy areas will appreciate that it is abrasion, tear, and puncture-resistant. TPO provides LEED credit qualification, and is Energy Star rated and Cool Roof Rating Council approved.
Whether you and your business care about a triple bottom line (people, planet, and profits) or just a single bottom line, thermoplastic polyvinyl chloride (PVC) is a roofing membrane infused with benefits. Clients who’ve installed it invariably discover that it’s a long-term, cost-effective solution. From an environmental perspective, it’s hard to beat short of a living green roofing solution. With its Energy Star rating, and its highly reflective, recyclable single-ply material, PVC is the obvious choice for environmentally sound roofing systems. Plus, with cool roof paybacks and LEED credit qualification, the benefits just keep adding up. From a durability perspective, oil, grease, and chemicals don’t like PVC’s highly resistant surface, and it’s incredibly easy to repair and maintain.
PVC is a solid option for restaurants, airports and commercial facilities with grease, oil, and chemical concerns, and environments that experience dilute acidic effluents. White reflective PVC roofing panels have a surface that provides a cooling effect that owners desire to provide energy savings in warmer climates. It has been tested in the industry for more than 35 years and now meets the most stringent codes in a wide variety of climates.
This type of low slope roofing material is referred to as modified bitumen due to its material makeup which consists of modifiers that are added to standard roofing asphalt to replace plasticizers removed during the distillation process. Bitumen is reinforced with fiberglass or polyester fiber matting in order to increase durability and strength.
The two most common types are SBS and APP. The use of SBS (styrene-butadiene-styrene) increases the flexibility of the membrane and allows it to have stronger expansion and contraction capabilities. A standard SBS modified bitumen roof system is a two-ply system applied in rolls that overlap the edge of the previous roll. The other type of modified bitumen roof is the APP (attactic polypropylene), which is used for its ability to increase the aging ability of the roof system. SBS is often the more popular system as the synthetic rubber additive increases the products flexibility.
Built up roofing systems, often referred to as BUR, have been utilized in the U.S. for over 100 years. These systems are a reliable waterproofing membrane that is field fabricated with layers of bitumen alternated with reinforcing felts. Commonly referred to as "tar and gravel" roofs, built-up systems redundant layers give it exceptional resistance to water and weather. Johns Manville has been a leader in BUR with 150 years of experience, and offers a complete line of fiberglass felts, including ply and base felts, and mineral surfaced cap sheets.
The bitumen typically used in built-up roof systems is asphalt, coal tar or cold-applied adhesive. The asphalt or coal tar is heated in a kettle or tanker and then applied by mop or mechanical spreader. Cold-applied adhesives do not have to be heated before application since these adhesives are solvent-based asphalts.
For years, low-slope metal roofing has been a favorite roof covering for commercial and industrial buildings because of its reliability against weather conditions. However, many building owners are recognizing some of the additional benefits to this high-quality option. Offering excellent durability and a sustainable footprint, metal roofing can extend the life cycle of your roofing system, offer a visually appealing exterior to your facility, and provide low maintenance requirements. Yet, to fully recognize those benefits, installation of your metal roof must be impeccable. The benefits of metal roofing include:
