When asked about roofing options, most people will think that residential roofing alternatives are the same that are used in commercial roof repair. But commercial roofing has very little in common with residential roofing. Residences generally use asphalt-based shingles, while a commercial roofing contractor has a wide variety of materials that are specifically designed for commercial applications. In particular, many commercial buildings are manufactured with flat roofs, while residential properties have peaks. Those completely different structures alone call for different roofing solutions.
Basic Types of Commercial Roofing
● Asphalt Roofing -- The most common type of roofing material for flat roofs, usually mixed with gravel, and mostly prevalent on older commercial buildings.
● Modified Bitumen -- Generally used to cover older asphalt roofs. It is much more flexible and rolled onto the roof substrate.
● EPDM -- This is commonly known as rubber roofing, but the newest types are applied with a hot-melt adhesive which gives superior performance and longer life.
● Metal -- Metal flat roofing is one of the oldest of the modern roofing methods. It can be covered by various roofing membranes.
● TPO Membranes -- This is a modern cousin of the rubber roof, made of thermoplastic sheeting which is so good that it even has an Energy Star rating.
● Duro-Last PVC Membranes -- This is a modern membrane made out of PVC. It is the most energy savings and cost-effective roofing material made. It is capable of covering many different types of roofing substrates.
Although there are other types of roofing material available, the types listed are the most common in use.
What's Right for your Commercial Business
It will mostly depend on the age of your roof and/or your building, the energy you want to save and how long you want it to last. For example, with an older building, you may just want to go with re-roofing using an asphalt covering. For more modern buildings, an EPDM or TPO membrane may be the most economical solution. For modern energy-efficient buildings, a Duro-Last PVC membrane might be the optimum answer.
The best course of action, before deciding on any commercial roofing choice, is to get a roofing inspection using the most up-to-date infrared technology. Infrared roofing inspections are able to see exactly where any water might be hidden beneath roofing through a temperature difference. This technology gives your roofing specialist, and facilities manager, the best course of action when deciding on what type of roof to have installed.
