Commercial Roofing Materials: What are the Options?

There is a wide range of variation in commercial roofs but they typically are broken down into three types: Flat Roofs, Low-Sloped Roofs and Pitched Roofs. The most common being a flat roof and is usually used for smaller structures. Flat roofs are also typically on the lowest end of the cost scale, whilst being the easiest and quickest to build. Low-sloped roofs are usually chosen for large-scale buildings, are low cost and easy to install and repair. Pitched roofs have the best drainage and therefore are the least problematic but are the most expensive of these three. Pitched roofs are also the hardest and most expensive to maintain.

The five most commonly used materials for these roofs are:

1. Thermoplastic Roofing- is extremely flexible and resistant
2. EPDM Roofing- is incredibly easy to install, maintain and repair
3. Photovoltaic Solar Panels- convert light energy to electrical energy but expensive to install and maintain
4. Green Roofs- are usually flat roofs covered I vegetation which absorbs heat and protects underlying roof
5. PVC Roofs- are incredibly fire-resistant and even more beneficial than EPDM roofing
