Commercial Roofing Types

Redefining Commercial Roofing Options

The world of commercial roofing has come a long way, presenting building proprietors with an extensive array of possibilities. Predominantly, commercial roofing encompasses flat and low-sloped roofs, which can be somewhat perplexing due to their similarities. Nonetheless, a seasoned roofing expert can help you navigate the selection process, ensuring you find the perfect blend of functionality, affordability, and long-lasting value.

BUR (Built-Up Roofing)

The term “built-up roofing” (BUR) originates from the on-site construction of a roof using layers of base sheet, interply sheets, and a cap sheet or alternative surface, such as gravel or liquid coating. Hot asphalt (bitumen) serves as the adhesive and waterproofing element between layers. BUR is fitting for the majority of flat and low-slope roofing applications.

APP and SBS Modified Bitumen Roofing

By introducing modifiers like APP (atactic polypropylene) and SBS (styrene-butadiene-styrene), traditional asphalt receives a performance boost. When combined with unblown (unoxidized) asphalt, these modifiers impart either plastic (APP) or rubber (SBS) properties, along with reinforcements such as polyester (excellent elongation capacity) or fiberglass (remarkable tensile strength). The outcome is a high-performance BUR system with significantly improved capabilities for flat and low-sloped roofs.

Self-Adhering Modified Bitumen Roofing

Self-adhered (SA) roofing has gained traction in commercial flat and low-sloped roofing projects due to its clean, simple, and safe installation process compared to other low-slope roofing systems. We proudly offer the CertainTeed Flintlastic® SA product line, manufactured using top-notch materials, and designed with specifications that ensure long-lasting and high-performing roofs.

Hybrid Self-Adhering Systems

Hybrid self-adhering systems merge modern SA roofing with traditional techniques. The base layer adheres to the roofing substrate, while the subsequent plies or modified cap sheets are installed using conventional methods – torch, mop, or cold adhesive.

Cool Roof Solutions

The basic concept of a cool roof lies in the fact that white roofs reflect solar heat while black roofs absorb it. However, contemporary roofing technology goes beyond this principle, and cutting-edge reflective roof products substantially lower roof surface temperatures. A cooler roof translates to reduced heat absorption into a building’s interior, heightened occupant comfort, decreased energy expenses, and a potentially smaller, more cost-effective cooling system.

Live Roofs

The concept of live roofing involves incorporating specially designed planter systems on a roof. Flat roofs make ideal candidates for live roofs. These green roofing solutions not only provide aesthetic appeal by creating natural vistas but also conserve water, diminish noise, and decrease overall building energy consumption.
