Ethylene propylene diene monomer (EPDM) rubber is a synthetic rubber known for its high tensile strength and resistance to tearing or cracking. Like thermoplastics, it is also one of the most durable materials that can be used as a waterproof membrane, with a lifespan of at least 50 years. It is a preformed elastomeric waterproofing membrane made of high-quality EPDM rubber. It has high tensile strength, elongation, tear resistance and resistance to weather, heat aging, ozone, UV rays, acids, alkalis and oxygenated solvents.
TPO (thermoplastic polyolefin) roofs are a single-layer white membrane used in commercial and residential roofs. Because the TPO roofing membrane is white, it reflects heat rather than absorbing it. No matter where the TPO roofing membrane is installed, it's important to consider the appearance of a white membrane. White gets noticeably dirty over time, so you should determine if it's important to see it from a window.
Just know that “dirt does not affect the functionality of the membrane”. As long as your TPO roofing membrane is properly installed, you can expect to use it for about 25 years. In addition to its chemical composition, a PVC roofing membrane has characteristics very similar to those of a TPO roof membrane. The installation process for both is pretty much the same.
Since 1990, the Bill Ragan Roofing team has been proud to help homeowners in Nashville and surrounding areas of Central Tennessee with all their flat roof needs. Whether it's to replace a flat roof or to fix a leak in a flat roof, you can trust us to provide you with high-quality workmanship that will give you peace of mind. The company is one of the leading waterproofing membrane companies offering solutions against water leaks. Structural waterproofing systems that combine hot melt liquid bituminous rubber with intercalated reinforcement can be used on roofs and podium covers to provide a seamless waterproofing membrane for roofs and podiums with high green areas and are sometimes specified for winter applications, where low temperatures are common.
In addition, the repair and renovation of existing structures also uses waterproofing membranes. Bituminous membranes tend to have a relatively short lifespan, only about ten years, and it's reasonable to expect minor problems to appear before that. EPDM (ethylene propylene diene terpolymer) roofs are a black synthetic rubber membrane that is primarily used in commercial and medical facilities. The waterproofing membrane prevents water leaks with a cover that does not allow water to come into contact with the materials of construction.
Like TPO, a PVC roofing membrane is a great option for a flat roof over a living room, as it will keep the room below cooler. Modified self-adhesive bituminous membranes are composed of asphalt, polymers and bonding agents, and may contain mineral stabilizers. These products come with a fiber-enhanced water-based polyurethane membrane that has been designed for a variety of waterproofing applications where the membrane must be covered with tiles, screeds, concrete beds, and more. Using insulation thick enough to insulate the entire structure costs more than using fabric insulation and glue the membrane.
Just be sure to consider the heat absorption of the black EPDM membrane roof system when making your final decision. Membranes that are applied with liquid are flexible enough to take whatever shape they are placed in. In addition, they have properties such as strength, tear resistance, weather resistance, UV stability and elasticity to close cracks that form under the surface. Let's learn more about waterproofing membranes and their attractive attributes that guarantee the best protection for your commercial building.
