Built-Up Roofing

BUR (Built-Up Roofing) systems are long lasting and durable. The BUR system’s, highly reliable waterproof membrane is field fabricated with layers of hot bitumen, alternating with plies of reinforcing felts that give it exceptional resistance to water and weather. Built-up roofing is laid down to conform to the roof deck, sealing all angles formed by projecting surfaces to create a single-unit flexible waterproof membrane.

Green Roof System

Green roofs are growing in popularity for their aesthetic and ecological benefits to modern buildings in urban areas. With years of experience waterproofing green roofs across Tacoma and Seattle, Bosnick Roofing is the preferred commercial roofing contractor of design professionals and building owners. Our green roof systems are built with roofing and waterproofing materials that are resistant to root growth and infiltration. We prevent algae resistance and root intrusion into field seams and flashings by installing durable waterproofing membrane systems that have been proven to last decades.

TPO

TPO is a high quality thermoplastic polyolefin roofing membrane – ideal for commercial, industrial, and institutional applications. TPO offers both the proven flexibility and weathering resistance of rubber and the performance of hot-air welded thermoplastic seams. Heat-welded thermoplastic roofing membranes are the fastest growing segment of the low-slope roofing market. Not only are TPO roofing systems durable and flexible, but they also come in a variety of colors.

Modified Bitumen

Modified Bitumen (BUR) is a long-lasting, durable and highly reliable waterproof membrane. BUR systems are field fabricated with layers of bitumen, alternating with plies of reinforcing felts. The redundant layers give it exceptional resistance to water and weather. Bosnick Roofing offers the following Modified Bitumen installation options:

• Hot Asphalt SBS
• Cold Applied APP
• Torch Applied APP

EPDM

EPDM (Ethylene Propylene Diene Monomer) is an elastomeric membrane ideal for commercial roofing for both new and re-roof low-slope roofing applications. EPDM single-ply membrane stands strong against tears, impacts, punctures and normal roof traffic. It’s rugged and offers excellent resistance to wind, ozone and ultraviolet light exposure. And it’s reliable, maintaining elasticity and flexibility that lasts.

PVC

Polyvinyl chloride (PVC) is a favored roofing membrane that provides excellent waterproofing protection. PVC’s popularity stems from its dependable, heat-welded seams, high reflectivity, superior physical attributes and resistance to water, chemicals, grease, fire and punctures. PVC membrane systems can be used for virtually any low-slope roofing specification.

Tapered Insulation – Polyiso

Polyiso is used in the roofing industry as a very effective and economical insulation product. It offers highly efficient thermal insulation values combined with high durability and flexibility. The popularity of tapered insulation has increased dramatically as architects, contractors, and building owners recognize the benefits of positive drainage for both new construction and re-roofing.
