Benefits of BUR and Mod-Bit

A built up roof system is a popular choice for buildings with low-slope or flat roofs. Often referred to by the acronym BUR, this system has been used for 100-plus years in the U.S.

What makes BUR systems so popular? They are known for providing excellent protection due to their redundant nature because they are made up of multiple layers of ply sheets and asphalt. These layers are then topped off by a cap sheet or a flood coat of asphalt and granules. The multiple plies provide resistance to weather and heavy-duty protection for the building.

Components of a Built Up Roof System

Built up roof systems can be constructed in a variety of ways. Often, the built up roof system starts with a base sheet installed over the polyisocyanurate (polyiso) insulation or cover board, typically through the use of mechanical fasteners. The base sheet serves as the bottom layer of waterproofing protection for the roof system and provides a surface that will allow subsequent sheets to be adhered with hot asphalt.

A layer of asphalt is applied over the base sheet for the installation of reinforcing felt, sometimes called a ply sheet. Many people picture kettles of hot asphalt being mopped onto the base sheet in order to install the ply sheet, but advances in manufacturing have created alternative options. For instance, contractors can choose to use cold-applied adhesive solutions instead of hot mopping asphalt and kettles.

Benefits of Built Up Roofing

Built up roofing owes its popularity to a number of benefits it provides, including:

• Time-tested technology. It's hard to argue with more than 100 years of history.
• Redundancy. Built up roofs provide many layers of protection, so if the top layer is damaged, the additional layers below will continue to protect the building from water intrusion.
• Guarantees/Warranties. BUR systems may be eligible for guarantees or warranties of up to 20 years, depending on the materials used and the system installed. Check with the manufacturer for guarantee/warraaty requirements and coverage.
• Reflective cap sheets available. White-coated cap sheets are availableto help reflect the sun's rays away from the building, which can help lower internal termperatures.

Benefits of Roof Coatings

• Preserve and extend the life of your roof.

Along with preserving and extending the life of your roof, coatings can provide a highly reflective surface that may help reduce energy costs by lowering the surface temperature of the roof. Additionally, coatings provide a seamless application that conforms to irregular roof surfaces, as well as seals cracks and splits in the roof surface. Coatings can be applied to address a variety of roofing concerns. When choosing a coating, it is important to consider the location and current condition of the roof, as well as ponding water, chemical exposure, high heat and UV radiation.

Types of Commercial Roof Coatings

• Silicone Roof Coatings

Silicone roof coatings have been designed with the customer in mind - to be durable, reliable and easy to apply. These coatings provide you with the opportunity to get your roof back to being watertight, while extending the service life of your roof. This means you can maximize your investment, increase energy efficiency and improve the safety of your roof without having to do a full roof replacement. Silicone provides the ability to delay the need for a time-consuming replacement so you can continue to focus on what matters most - running your business.

• Acrylic Roof Coating

Acrylic roof coatings cure to form a durable, continuous elastomeric membrane over the surface of your metal roof. Once applied, they form a seamless, watertight seal over the entire roof; including around vents, flashings and protrusions. Our product is a self-flashing, lightweight acrylic roof coating that provides a continuous membrane while sealing seams and eliminating leaks. This coating is energy efficient and environmentally friendly, as well as being highly reflective and contains no VOCs. Durable with excellent weathering capabilities, this advanced liquid-applied system restores metal roofs and can eliminate minor metal roof problems.

• Other Roof Coatings

Aluminum coatings can be applied to bitumen based roofs and certain metal roof applications. Bitumen based roofs can be re-saturated and copolymer coatings can be applied to single ply and metal roofs.

Benefits of TPO and PVC

Flexible protection.

• TPO Roof Systems

TPO membranes are made with a co-polymerized rubber that allows them greater flexibility in cold climates. This membrane is best recognized for having the benefits of EPDM and PVC systems, at a more economical cost. TPO membranes are white and highly-reflective, making them an excellent choice for those looking to reduce energy costs. In addition to being ENERGY STAR rated, TPO’s recyclability makes it an environmentally conscious system. Additionally, TPO roofs are durable and resist dirt, bacteria and debris build-up making them highly resistant to tears, punctures and impact damage.

• PVC Roof Systems

First installed in the early 1960’s, PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing. Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. To this day, PVC membranes remain incredibly versatile, chemical resistant and are highly recommended for roof-over projects. They are available in a variety of colors, thicknesses, widths, and reinforcements, making them an excellent option for almost any roofing project.

Along with the environmental benefit of using (fewer) fossil fuels in the manufacturing process, PVC is highly reflective/UV resistant, making the membrane an energy efficient option for warmer climates.
