Membrane roofing is applied in big sheets and fused together at the joints to form a continuous surface. Because the sheets are bonded together, there are no seams to cause leaking problems. One of the most successful types of membrane roofing is made from sheets of rubber, or Polyvinyl Chloride (PVC). Membrane roofing is lightweight and durable. Usually, it has a light-colored finish that reflects sunlight and reduces cooling costs inside the building. Not only is membrane roofing an excellent way to waterproof your roof, but it is also one of the most affordable. Fast becoming a popular type of roofing, you may want to consider membrane roofing for your new warehouse.

Types of Membrane Roofing

The three most common types of material used in membrane roofing are synthetic rubber, thermoplastic, and modified bitumen.

Synthetic Rubber (Thermoset). Thermoset is a single-ply rubber roofing membrane. This membrane is made from large flat pieces of synthetic rubber that are chemically bonded together at the seams to form one continuous layer. The sheets are often joined with contact adhesive or tape. The finished roof is usually between 0.75 to 1.5 millimeters thick. Thermosets are famous for their ability to withstand a broad range of exposures including chemicals found on roofs, ozone, the damaging effects of the sun’s rays, and extreme weather conditions. This synthetic rubber roof is extremely durable and superb for second generation application. It is widely used on low-slope buildings in the United States as well as worldwide and works well on big box stores with large open areas. • Synthetic Rubber (Thermoset).

EPDM (ethylene propylene diene terpolymer) Roofing is the most commonly used thermoset membrane and resembles an inner tube. The two primary ingredients of this roof covering are derived from oil and natural gas.

Long-lasting and easy to install, maintain, and repair, thermoset roofing is a viable option to consider!

The Thermoplastic membrane is similar to synthetic rubber, but the method of bonding the sheets together is different. Thermoplastic membranes are welded together using solvents, or heat, creating a seam that is as strong as the material itself! The material can be softened and hardened as needed. Most thermoplastics can be re-welded if necessary. Because they have a low-temperature flexibility and a high-temperature tolerance, they are exceptionally durable. They are resistant to ultraviolet rays, ozone, and chemicals. These membranes also include a reinforcement layer that provides extra strength. Their outstanding toughness makes them highly resistant to fire, tears, punctures, and bad weather.

PVC (polyvinyl chloride) and TPO (thermoplastic polyolefin) are the most common thermoplastic membranes. These highly reflective roof coverings are also well suited for second generation application.

Modified Bitumen. Modified bitumen roofing is a blend of traditional and modern technologies. An asphalt-based roofing system reinforced with fiberglass and polyester mats; this roofing has a high resistance to foot traffic, tears, and punctures.

Polymers such as APP (Atactic Polypropylene Polymer) and SBS (Styrene Butadiene Styrene) added to the asphalt modify elasticity and temperature flexibility of the membrane. APP systems give resistance to foot traffic and enhance tensile strength. SBS systems increase resistance to fatigue and brittleness at cold temperatures.

The pieces of material can be connected and sealed by melting with heat, hot mopping, cold applied adhesives, or self-adhesive membranes. No matter how the seams are sealed, all the methods ensure a waterproofed roof for years to come. All applications are safe and easy to install regardless of outside temperature. Modified bitumen roofing comes with either a smooth or a granular surface and is available in a variety of colors to fit the environment of your building.
