Commercial roofing materials need to be suitable for the unique conditions, including climate, in which they are installed. Not surprisingly, hot weather poses some specific challenges for a roof, as does the type of building it’s installed on and other situations. So, it is important to be mindful of making a careful choice about your commercial roofing. Out of all the available options, polyvinyl chloride (PVC) membrane makes for an excellent roofing material just about anywhere. Here are some reasons why.
PVC Provides Excellent Durability
Most commercial buildings have a flat roof, and PVC has been covering flat roofs for decades. Today’s reinforced PVC membranes provide a high level of durability in the form of flexibility and resist issues like impact and tears.
PVC Meets Rigorous Requirements
PVC roofing membranes from all manufacturers undergo standards testing. According to the National Roofing Contractors Association (NRCA):
Standards prescribe levels of acceptability or approved modes to be used in building construction (including roof systems) as bases of comparison. Test standards prescribe test methods and, sometimes, minimum acceptable results. Rating standards establish measurement methods to ensure similar products can be compared on the same bases.
One of the primary testing organizations is the American Society for Testing and Materials (ASTM). From the ASTM website:
ASTM's roofing standards are instrumental in specifying, testing, and evaluating the dimensional, mechanical, and performance requirements of various forms of roofing systems. These systems are assembled in the uppermost part of building structures to provide protection and insulation from external elements such as rain, sunlight, and heat. These roofing standards are helpful in guiding product manufacturers, construction companies, architectural firms, and other producers and end-users of these parts and components in their proper fabrication and installation, as well as the possible hazards involved during these procedures.
PVC Stands Up to Harsh & Hot Weather
Harsh weather, especially over long periods of time, can obviously be brutal on a commercial roof. Intense sun and heat can be especially damaging – plus can add to a facility’s energy bills. PVC roofing systems have a proven record with respect to durability and reflectivity, saving energy costs for buildings during hot summer months. PVC membrane reflectivity and emissivity are rated by ENERGY STAR, the Cool Roof Rating Council and the State of California for Title 24 requirements and PVC systems generally score very well – especially white membranes.
PVC Can Handle Tough Rooftop Conditions
Roofs on commercial buildings can be put under some tough conditions, but PVC can handle that. For example, it offers a high level of resistance for many chemicals and other substances that can deteriorate other systems. PVC is especially durable on restaurant roofs that have to handle greasy exhaust.
All in all, PVC makes for an excellent roofing material for all types of commercial buildings in all types of climates.
