Built-up Roofing (or BUR) is the “Old Reliable Standby” of roofing which can be used on commercial, industrial and institutional buildings. BUR is used on flat or low-sloped roofs and consists of multiple layers of bitumen and ply sheets.
The Advantages of BUR
Built-up roofing systems have had a long-standing popularity, due in large part to its success and proven reliability. The number of 20, 30 and 40-year-old BUR roofs still in excellent condition attests to this fact. Specifically, BUR roofs offer:
The Components of a BUR system include:
The Roof Deck • A Vapor Retardant • Insulation • Membrane • Surfacing Material
At the heart of this roofing system is the roofing membrane, which consists of roofing bitumen and multiple reinforcing plies of roofing felt.
Roofing bitumen is the primary adhesion/waterproofing agent used between roofing plies. Bitumen arrives at the job site in solid form, but is heated and applied as a liquid. Roofing bitumens may be either a product of petroleum refining (asphalts) or a product of the coal-cooking process (coal tar pitch).
Multiple reinforcing “plies” are asphalt-coated roofing sheets or felts installed in three or more layers to strengthen and stabilize the BUR membrane.
BUR roofing membranes can be protected from solar radiation by embedding gravel in the bitumen, applying a surface coating or applying a granular-surfaced “cap” sheet. Light-colored surfacing materials can be used to reflect heat from the building. In addition, surfacing agents can provide additional fire protection, and the are FR Rated
BUR applied for maximum performance:
It’s critical to get secure bonding of the roofing felts (plies) using bitumen. To achieve this bond the roofing contractor applies thin, uniform moppings of bitumen. This waterproofs the system and ensures proper adhesion for fusing the membrane system together.
The temperature of the bitumen is critical. By heating it to the proper temperature the roofing contractor gets the right viscosity for proper mopping. The contractor heats the bitumen to its EVT or Equiviscous Temperature, the temperature at which it can be most effectively mopped into uniform layers. Each batch of bitumen should be labeled by the supplier with its EVT. Once felts are rolled into place on the heated bitumen applicators pull brooms or squeegees over the felt or use some other method to make sure that its embedded in the bitumen. Typically, membrane ply construction is defined by headlap, endlap, and sidelap.
The application of Built-Up Roofing systems is detailed work, but the professional who pays particular attention to those details such as curbs, walls, flashings or other projections that interrupt the membrane, achieves a quality, efficient, long-lasting product for the building owner.
The Advantages of EPDM
Reinforcing Option Available
45/60/90 Mil. Thicknesses
Easily Repaired
Excellent UV Resistance
User Friendly Installation
Little or no Future Maintenance
EPDM Application
Ballasted
The ballasted system presents an easy, economical roofing solution for buildings that can accommodate an average ballast weight of 10 to 12 psf. Because the system is easy to install, it’s ideal of applications where eventual changes in building height or contours are envisioned.
Mechanically Attached
This system presents a lightweight, cost-effective option if you wish to limit the weight load on the building or to reinforce an existing roof. Insulation, when necessary, is mechanically attached to the deck, with the membrane affixed at set intervals using linear attached batten strips to protect against wind uplift.
Fully Adhered
This system is especially recommended for applications over an existing substrate where the use of mechanical fasteners is undesirable, or unfeasible. The insulation is installed using hot asphalt, with the membrane fully adhered to the secure insulation. The system may also be installed over insulation that is attached using conventional fastening methods where applicable. It’s also ideal for special configurations such as domes and barrels.

The Advantages of Modified Bitumen
Good Resistance to Foot Traffic
Highly Puncture & Tear Resistant
Hot, Asphalt & Adhesive Applications
Flexible
Excellent Chemical Resistance
APP Modified Bitumen
This membrane is comprised of high quality asphalt that has been specially compounded with Atactic Polypropylene polymer to enhance tensile strength and resistance to foot traffic. Available in a smooth or granular surface and an assortment of colors. This system is installed easily and efficiently with a propane torch or cold adhesives and a trowel (which is what we prefer).
SBS Modified Bitumen
This membrane is formulated with high quality asphalt, modified with Styrene-Butadiene-Styrene polymer. This polymer modification improves elongation, low temperature flexibility and fatigue residence. This system is available in either smooth or granular surface in an assortment of colors. This system is installed easily and efficiently with hot asphalt, propane torch or cold adhesives and a trowel.
The Advantages of PVC Roofing (Polyvinyl Chloride):
Excellent Resistance to Chemicals
Fiberglass Reinforced – Strong
Excellent Seams – Heat Welded
White Color Reflects Sunlight
