Asphalt

Asphalt: A black, tarrish material which largely consists of bitumen compounds. Asphalt can be found naturally or can be produced through petroleum processing. Asphalt is the basis for many flat roofing systems, such as modified bitumen roofing.

Asbestos

Asbestos: a family of natural, fibrous, and impure silicate-based materials. Asbestos, originally used to reinforce roofing materials, has been outlawed due to health concerns and is no longer used in construction jobs.

Ballast

Ballast: Heavy materials, such as stone aggregate or precast paver blocks, used to hold commercial roofing membranes in place.

Bitumen

Bitumen: An unstructured, semi-solid mixture of complex hydrocarbons created from organic materials. Asphalt and coal tar products are composed of bitumen materials and comprise two of the most commonly used roofing systems in the industry.

Creep

Creep: Deformation of a commercial or industrial roofing system caused by the slow shifting and settling of the roof membrane.  that results from continuous thermal stress or loading.

Degradation

Degradation: The eventual collapse and breakdown of the physical properties and appearance of a commercial or industrial roofing material due to exposure and elemental damage.

EPDM

EPDM: Ethylene Propylene Diene Monomer, commonly called “rubber roofing”, is a strong material highly resistant to damage, weathering, and water intrusion.

Felt

Felt: Felt materials are used as a base for many commercial and industrial roofing systems. Felt fabrics are manufacture from vegetable-based fibers, asbestos fibers, or fiberglass products.

Flashing

Flashing: Flashing consists of sealing components designed to weatherproof and close a flat roof roof system along the edges to prevent water intrusion and damage. Flashing usually consists of a metal sheet and can be bent and formed to cover openings and cracks.

Heat Welding

Heat Welding: A technique for melting and fusing overlapping edges or sections of modified bitumen, thermoplastics, or various thermoset roofing membranes through the application of heat and pressure. Heat application usually consists of using open flames to melt and bond the products.

Puncture Resistance

Puncture Resistance: Materials designed to withstand heavy foot traffic and capable of resisting sharp objects. Commonly used around rooftop machinery, such as AC units and venting structures.

PVC

PVC: Polyvinyl Chloride, a thermoplastic single ply roof membrane system commonly used for commercial and industrial roofs.

Reflectivity

Reflectivity: The level of resistance a roofing material possesses to infrared and UV light sources.

Reinforced Membrane

Reinforced Membrane: A commercial or industrial roofing system strengthened by the addition or incorporation of reinforcing materials. These materials include fiberglass products, polyester-based mats or scrims, nylon, and polyethylene materials.

Self –Adhering Membrane

Self –Adhering Membrane: A commercial and industrial roofing membrane capable of quickly and efficiently adhering to a surface through the removal of a release paper.

TPO Roofing Materials

TPO Roofing Materials: TPO (Thermoplastic Olefin) membranes are a blend of polypropylene and ethylene-propylene polymers. TPO membranes can be blended with colorants, flame retardant materials, UV resistant/absorbing materials, and other substances designed to increase the product’s lifespan. TPO roofing materials are 100% recyclable.
