We have experienced and certified specialist crews for all of types of flat roof installations. Flat roofing is a common, time-tested and practical roofing solution for many homes and businesses, in roof transitions, observation decks, and when building heights conflict with municipal codes.

Selecting the most appropriate material for your overall roofing system is one of the most important decisions you can make. In small or large installations, it is important to follow proper flat roofing practices to ensure many years of trouble free service. 

Traditional flat roofing materials typically have a shorter life expectancy than roofing materials used on pitched roof slopes. Thus, in certain situations, it might be beneficial to use more expensive and state-of-the-art flat roofing materials.

The more popular flat roofing materials use rolled base-ply membranes nailed to the roof deck. A granulated surface cap sheet is then applied over the base with troweled adhesives, torching or self-adhering adhesives. This type of system typically provides for a twelve year life expectancy. Additional plies added under the cap sheet provide additional life expectancy in three year increments. To maximize the life of these roofs, water pooling, debris buildup and foot traffic should be kept to a minimum.

The newer more expensive flat roofing systems comprise of single-ply weather-resistant materials that are either heat welded at their seams, glued on the seam overlaps, or some combination of both. These systems are most commonly highly reflective vinyl or PVC derivatives that usually provide for a long thirty-year service life (barring any punctures or over stretching of the material). These materials make excellent complete flat roofs with some systems offering trouble free service for 50 years.

Built-Up and Hot Mopped Roofing:

The original form of flat roofing that uses rigid insulation board of tapered foam or Perlite. Several plies of fiberglass felts are layered in hot melted asphalt and topped with hot asphalt and embedded with gravel, or a granulated cap sheet membrane.

Modified Membrane and Bitumen Rubber Roofing:

These are modern flat roofing materials which are designed to replace traditional hot asphalt and gravel embedded roofs. These materials weather well and resist the damaging effects of pooling water. With a variety of use applications and acceptable methods of installation, these new materials are a good solution for most roofing needs.

Thermoplastic (TPO) Roofing Membranes: 

These materials are most commonly PVC (Polyvinyl Chloride) vinyl membranes or TPO (Thermoplastic Olefin) membranes. The material is applied by using of hot air heat welding, chemical bonding with use of solvent adhesives or any combination of the two. These are the most expensive flat roofing systems and are engineered to last for many years. PVC and TPO roofing materials are easily repaired by heating or chemically bonding a repair patch.

Foam Roofing

Commercial Poly-Urethane and poly- based products offer fast application and improved insulation. The benefits quickly outweigh any additional costs of a quality urethane foam roof. Roof area preparation is critical, but has a quick application process. The material is very durable and depending on application thickness can offer exceptional thermal insulation properties.
