Most commercial roofs seem pretty similar to an untrained eye. The vast majority of buildings feature some kind of flat roofing system, but don’t be deceived. There are a range of differen types that are suitable to different types of buildings, different climates, and even different budgets.
If you are planning on constructing a new building or you’re replacing the roof on a current property, you should know a bit about the different types of roofing systems. The four main roofing types are thermoplastic roofing, ethylene propylene diene monomer (EPDM), photovoltaic panel roofing, and green roofing. Let’s take a closer look.
An increasingly popular option for commercial roofing, thermoplastic systems are constructed from highly durable materials that are also flexible even in low temperatures. They tend to tolerate a wide temperature range, and they are especially resistant to ultraviolet, ozone, and chemical exposure. Thermoplastic roofing systems have a typical lifespan of 20 years or more and offer great resistance to fire, winds, and other damaging factors.
EPDM roofing systems provide exceptional durability and versatility, and as such they are one of the longest lasting roofing systems. Moreover, EPDM roofs are easy to install and maintain than other roofing types so they continue to be a popular choice for new construction and roofing repairs. They’ve been popular since the 1960s and are frequently used because they are relatively inexpensive as well.
Photovoltaic Panel Roofing
The rising cost of energy has motivated construction professionals to come up with creative solutions to heating and electricity costs. Photovoltaic panels are an excellent roofing option because they allow building owners a sustainable energy source. With solar panels installed over a roofing system, energy from the sun is absorbed and converted so that it can be used to power and heat a building.
Finally, green roofs are another environmentally friendly that are gaining considerably in popularity in recent years. Typically installed on flat roofs, green roofs are either partially or completely covered with soil and vegetation over a waterproof membrane. Green roofs are a great choice because they not only insulate a building much better (thereby reducing heat loss and gain) but they also have added benefits for the surrounding urban environments. Not only do green roofs help ameliorate the urban heat island affect by absorbing heat, but they also provide a natural habitat for birds and other wildlife. More importantly, green roofs have an impressive lifespan, so while they are more expensive to install, they can save money in the long term.
Not all roofing systems are appropriate for all building types. Make sure to discuss your roofing options with a qualified professional to ensure you get the best roof for your property.
