Modified Bitumen Roofing
Modified Bitumen Roof Systems are available in two types: Styrene Butadiene Styrene (SBS) and Atactic Polypropylene (APP).
While both systems sheets can be reinforced with glass or polyester, they do differ in how they are installed on the roof. SBS is typically installed with hot asphalts or cold adhesives. APP is almost always installed utilizing the torch method. Our team of professionals at Advantage One Roofing will assess your roof and determine the best approach for your facility.
Both Modified Bitumen Roofing System types can be surfaced with either factory surfacing ceramic granules or with metallic laminants such as copper or stainless steel. If a cap sheet is not utilized, aluminum coatings or white acrylics can be applied to enhance the system’s UV and oxidation resistance.
Benefits of Modified Bitman Roofing:
- Polymer modification to asphalts result in greater elongation and the ability to accommodate building movement
- Ability to manufacture rolls in plants, providing better quality assurance
- Versatile application options: hot asphalts, cold adhesives, or hot air
- A variety of modified types and mileages are available to better provide resistance against foot traffic and common rooftop abuse when needed
BUILT UP ROOFING
Built-Up Roofing (BUR) is one of the oldest low-slope roofing systems that is applied to commercial roofs today.
It’s 120 year track record is unsurpassed in the roofing industry, having continued to provide commercial property owners with dependable services.
Built-Up Roofing systems are composed of either asphalt or coal tar pitch and are assembled on the rooftop. Fibrous glass or organic rag felts are used in the installation. After the felts have been installed, a surfacing material such as slag or gravel aggregates are set into place. Surfacing materials protect the membranes and also help protect the roof from UV degradation. In addition, a smooth surface asphalt BUR system can be coated with aluminum paint or white reflective materials to further help fight against the effects of UV and cut down on cooling costs.

What makes Advantages One Roofing’s warranted EPDM (Ethylene Propylene Diene Terpolymer) such an outstanding roofing system? It stands up to almost anything nature’s elements can throw at it. EPDM is dimensionally stable, yet expands and contracts with building movement, and withstands extreme temperatures.
Ballasted: The ballasted system presents easy, economic roof solutions for buildings that can accommodate an average ballast weight of 10 to 12 psf. Because this system is so easy to install, it’s ideal for applications where eventual changes in building height or contours are expected.
Mechanically Attached: A lightweight, cost-effective option if you wish to limit the weight load on an existing roof. Insulation, when necessary, is mechanically attached to the deck. The membrane is affixed at set intervals using mechanical fasteners to protect against wind uplift.
Fully Adhered: Recommended for applications over an existing substrate where the use of mechanical fasteners is undesirable. The insulation is installed using either hot asphalt or insulation adhesives with the membrane fully adhered to the secured insulation.
An Overall Sterling Performer
Advantage One Roofing’s EPDM roofing system is practically maintenance free:
- Virtually immune to ozone, UV radiation and cold cracking
- The material does not become brittle from plasticizer migration
- Life expectancy as long as built-up roofing systems
- Warranted up to 20 years for labor and materials
- Proven to be a highly effective and economic single-ply roofing membrane for over three decades
- Unsurpassed in durability and leak resistance
There are times when you need a new roof, but there are also times when options such as our copolymer liquid applied coating can help extend the existing roof’s serviceability.
Copolymer Coating can be used on:
- Modified Bitumen
- Single-ply EPDM
- and Built-Up (BUR) Roofs
How Copolymer Coating Enhances Your Roof System
Parapet Walls: Leaks can occur through concrete blocks or brick walls above the roof system’s flashing height. Our copolymer coating fills in gaps, cracks and seals porous mortar and masonry.
Metal Roof Repairs: The copolymer coating has the ability and strength to expand and contract with the metal panel roof system. It is an excellent and economical repair solution that can be applied at open streams and joints found around rooftop penetrations.
Reflectivity: White coatings offer excellent ultra violet (UV) resistance and can help lessen heat and stress on air conditioning units. Reducing the rooftop surface temperature with a complete coating system may result in potential energy savings.
Safety/Hazard Awareness: Rooftop safety is a very high priority for many of our customers. Yellow safety lines can be applied to alert people to areas such as open perimeters, skylights or other potential dangers.
Potential Additional Applications: Our coatings can be used to apply messages, company logos and symbols to your roof. Tanks and patios are also excellent candidates for our coating solutions.
Ductwork: After years of weather exposure, your sheet metal ductwork corrodes and becomes loose at the seams. Our liquid copolymer coating bonds extremely well with sheet metal and provides outstanding weatherproofing
How CentiMark’s Acrylic Coating Enhances Your Roof System
CentiMark’s acrylic coating system is an advanced liquid-applied system that restores metal roofs and that can eliminate a myriad of metal roof problems.
Acrylic coatings are made of high quality aqueous acrylic polymer that cures to form a durable, continuous electrometric membrane over the surface of your metal roof. It adheres to almost any metal surface to form a seamless, watertight seal over the entire roof, including vents, flushing and protrusions.
It is also extremely durable and able to withstand the most common roof hazards. These include ultra-violet light, temperature extremes, mildew, normal foot traffic and building movement. The system is also water-based, so it is safe to apply in almost any situation. Additionally, it doesn’t release toxic fumes, and the material is non-flammable.
Numerous state government and power company programs, rebates and incentives make choosing sustainable products and practices fiscally rewarding for commercial property owners, helping them adopt green strategies for their facilities. Some of the most financially rewarding of the state and local power company programs can be found at the Database of State Incentives for Renewables & Efficiency.
IRS Green Construction Tax Incentives
In addition to programs that vary between states and power companies, there is also a federal tax deduction available through the Internal Revenue Service for commercial property owners who bring their property up to a minimum level of energy efficiency and was enacted in the 2005 Energy Policy Act. It applies to buildings that were retrofitted after December 31, 2005 and prior to January 1, 2009.
To qualify, the building must have 50% reduced energy costs resulting from improvements in the energy efficiency of the building’s heating, cooling, ventilation, hot water and interior lighting compared to a reference building meeting the minimum requirements of ASHRAE 90.1-2001 Standard.
The amount of the deduction is $1.80 per square foot of the property if the 50% improvement is documented. Lesser deductions are available up to $0.60 per square foot if the energy improvements reach a minimum level of 16 2/3% above the reference building mentioned above. The Department of energy also lists acceptable computer programs hat can be used to calculate and verify the energy improvement. It is unknown whether this tax deduction will be extended beyond January 1, 2009 at this time.
