We work with all types of roofing systems, check out our system overviews below to see what would work best for your project.
built up roofing system (BUR)
BUR systems are composed of alternating layers of bitumen (asphalt) and fabrics called roofing felts. The felts are reinforced with either glass-fiber mats or organic mats (ply sheets) and when joined with the bitumen form a durable roofing membrane. The number of “plies” on a roof implies the number of layers, i.e. “four plies” denotes a four-layer flat roof membrane system. BUR systems are redundant, meaning if one layer breaks down, multiple remaining layers provide immediate protection. These systems also offer great tolerance for building stress and resistance to thermal shock, high puncture resistance and outstanding membrane strength and toughness for proven long-term durability. BUR systems can include SBS, fiberglass or organic felts and offer many options to suit a variety of building needs. The key to this system is the repetitive layers. BUR also is known for superior fire resistance from external flames. Reflective surface options also are available to offer maximum membrane protection, superior puncture resistance and high resistance to foot traffic and mechanical maintenance.
Modified Bitumen (Mod Bit) Systems
Mod Bit systems are factory-fabricated layers of asphalt that are “modified,” using a rubber or plastic ingredient for increased flexibility and combined with a reinforcement for added strength and stability. Membranes are usually installed as a 2 ply system with a base sheet and a granulated cap sheet membrane. Modified bitumen roofing and waterproofing systems are quickly installed, easy to maintain and cost efficient. They can be hot mopped like traditional BUR but also may be applied as a torch down product, cold applied in adhesives and also come with self adhesive backings.
single ply systems
Single ply commercial roofing membranes are flexible sheets of compounded synthetic materials that are manufactured in a factory to strict quality control requirements. Single ply roofing systems provide strength, flexibility and long-lasting durability. The inherent advantages of these pre-fabricated sheets are the consistency in quality of the products that are manufactured, the versatility in their attachment methods and their broader applicability. There are two major categories of single ply membranes: thermosets and thermoplastics.
- Thermoset membranes are compounded from rubber polymers. The most commonly used polymer is EPDM or Ethylene Propylene Diene Monomer. EPDM is a durable rubber roofing solution and available in both black and white. Thermoset membranes are successful for use as roofing materials because of their proven ability to withstand the potentially damaging effects of sunlight and most common chemicals generally found on roofs.
- Thermoplastic membranes are fabricated from polymers which soften when heated and harden when cooled. These factory-made sheets are applied on the job site using one of the standard installation techniques for sheet membrane systems (fully adhered, mechanically attached or ballasted). This process is repetitive provided the material is not heated above the point at which decomposition occurs. The membranes can be welded together with heat or solvents, and when welded, develop a bond strength which equals or surpasses the strength of the base material. Polyvinyl chloride (PVC), blends or alloys of PVC and thermoplastic polyolefins (TPO) are the most common types of thermoplastic roofing membranes.
