Modified Bitumen Systems

Is It the Right Choice for You?
Modified Bitumen is a material consisting of bitumen which has been modified through the inclusion of one or more polymers and may contain stabilizers and other additives. Modified Bitumen roofing membranes contain reinforcing materials:

• Fiberglass
• Polyester Mats
• Combination of Both

The recovery properties of this roofing system allow it to accommodate recurring stresses, reducing the possibility of a fatigue failure.

  • • Proven track record of performance
  • • Superior waterproofing characteristics
  • • Perfect for industrial and commercial applications
  • • Excellent elasticity and durability
  • • Holds up well to foot traffic, dropped tools and other abuses
  • • Ideal for roofs with extensive mechanical equipment
Single Ply RoofsSingle Ply Roofing Systems

Single ply systems are now more advanced than ever before as they remain pliable through wide temperature fluctuations. However, they require expert installation to insure longevity.

In some cases, a single ply roof can be applied directly on top of the existing roof system.

  • EnergyStar• Recommended for industrial and commercial applications
  • • Manufactured under strict quality control requirements
  • • Light-colored, reflective surface can reduce energy consumption
  • • Lightweight solution that can accommodate unconventional roof designs.

  • This gives these roofing systems superior resistance to the elements.

Precision Sheet Metal Fabrication

SheetmetalWith our state-of-the-art computerized equipment, our talented sheet metal engineers and skilled craftsmen work together to custom design, fabricate and install gutters and downspouts, duct work, metal copings and fascias, and other fabricated sheet metal products.

Lightweight Concrete

Lightweight ConcreteLightweight concrete insulates very well and among its advantages are less need for structural steel reinforcement, smaller foundation requirements, better fire resistance, environmentally safe and most importantly – it can serve as an insulation material. These advantages retain the R value and makes lightweight concrete superior to rigid boards for years to come.

Built Up RoofsBuilt-Up Roofs

The Built-Up Roofing System is made of bituminous materials with reinforcing plies of fabric or felt attached to a substrate and bonded to each other with hot or cold applied bituminous materials. The bitumen serves as waterproofing and as an adhesive
binding the plies.

Reinforcing fabrics or felts may be organic, inorganic or both. The exposed surface of the membrane is often surfaced with protective materials such as an aggregate, mineral cap sheets or a variety of coatings. As an integral part of the membrane, these surfacings have an impact on overall built-up roofing performance.
