Any commercial roofing company needs to know a lot about different types of roofs and how these roofs fare in the immediate area. EPDM and TPO systems each have their pros and cons, but many choose the TPO type because it is less expensive. When the budget isn’t tight, there are a lot of factors to consider.
EPDM roof systems generally hold onto more moisture while a TPO system is better at handling and getting rid of moisture. Black EPDM holds onto the warmth of the sunlight, and this can make the building uncomfortable during the hottest months of the year. A TPO roof will reflect light with its white surface. Sometimes, a building will have to choose either an EPDM or TPO roof that meets the local building ordinances. New green laws often dictate the best roof based on how environmentally friendly it is.
Sometimes, it’s the type of business that counts. An EPDM roofing system should not be used on restaurants because it can add heat to a building already heated up by a kitchen. When choosing which of these roofing types to use on a building, you need to consider the budget of the project, the local building laws, and how much heat the roof may generate.
