From industrial commercial facilities to commercial buildings, no job is too large or too small. We offer proven expertise in all roofing services, systems and materials including:

Single-Ply Roofing Membrane

The list of manufactured single-ply roofing membranes is long, including Vulcanized Elastomers such as EPMD and Neoprene; Non-vulcanized Elastomers such as CSPE, CPE, PIB and NBP; and Thermoplastics such as PVC and EIP. Each manufacturer provides material specific warranties on these single-ply membranes. Cabral is experienced and familiar with each type of single-ply membrane. We know their benefits, their limitations, and we are trained in all manufacturer-recommended installation procedures.

Cold Applied Membrane

Seamless, monolithic roof membrane materials include:

  • Asphalt emulsion and chopped glass (bitumen BUR waterproof membrane surfacing).
  • Spray-applied asphalt adhesive and asphalt-coated ply sheets ("cold BUR").
  • Asphalt emulsion and polyester fabric reinforcement (reinforced seamless monolithic membrane).

Polymer Modified Bitumen Roofing

Polymer modified bitumen membranes are engineered waterproofing materials using asphalt-based bitumen and APP or SBS polymers. Modified bitumen membranes are attached to the substrate by hot asphalt, heat fusing or cold-applied adhesives to form a strong, flexible, puncture resistant material. They combine the reliability of time-proven hot asphalt-applied BUR roofing systems with the modern benefits of flexible plastic additives and polyester/fiberglass reinforcement roofing technology.

Built-up Roofing (BUR)

Applied over commercial property low-slope roof decks, a BUR bituminous membrane consists of two or more plies of fiberglass reinforced felts saturated with bituminous materials. Deck separator sheets, base sheets and various surfacing options are not considered components of the waterproof membrane.

Commercial Steep Roofing

Many buildings are designed to present the impression of traditional steep roofing when viewed from street level. The visible portion of these "mansard" style roofs may employ metal, composition shingles, clay tile, concrete tile, slate, wood shingles or shakes as architectural surfacing for the waterproof underlayment and associated trim and metal flashings attached to the steep slope deck. Proper installation and repair of these steep slope deck systems requires careful and knowledgeable consideration of many factors, including deck support members, deck construction, insulation, underlayment, fasteners, adhesives, caulks, high wind uplift considerations, edge metal, trim, metal flashing, surfacing style, and color. Cabral understands the complexities of steep roofing.

Wall and Below-Grade Waterproofing

Cabral also offers entire exterior building envelope waterproofing solutions. We are expert in the application of modern waterproofing systems and materials, including asphalt, coal tar, butyl rubber, EPDM, PVC, modified asphalt, bentonite, penetrating sealant and 100% acrylic emulsions.
