Roofing Materials

Whenever you build a building whether it is private or commercial, one of the key components is the roof. A good roof is essential to protect the rest of the building and needs to fit in with the structural design. If it is not done well or is not compliant all it will take is some nasty weather for it and the building itself to be ruined.

For commercial structures, there is commercial roofing materials that is are used to seal in the top of the structure and protect it. The key difference between commercial roofing and residential roofing is that the latter tends to slope steeply whereas commercial often is flat. This means materials used in commercial roofing are also different for the most part and below is a look at the common ones used and their pros and cons.

Commercial Roofing Materials

Slate Roofing

slateSlate can last for hundreds of years so if longevity is what you are looking for this is a good option. It is expensive, but when you consider the long term this works out to be as cost effective, if not the most cost effective, as any other roofing material. It is one of the most attractive of the roofing materials and can be found in various thicknesses and sizes. Since it has a natural resistance to things like moss and algae it is lower maintenance then other options and is water repellent and fireproof. Weather like wind and hail can easily be withstood and it is eco-friendly. When it is time to remove them they can be recycled or discarded without concern for the environment.

Asphalt Roofing

asphalt-roofingShingles made from Asphalt or more often used when a commercial roof has a steep slope. You can get various styles and colors, putting them up is easy and they are at a fair price. But this material is not durable, it does not have a long life and deteriorates quickly. It is also not string against high winds which can blow them off roofs. If the sun gets very hot where you are the Asphalt shingles are not a great option as they scar easily and are also prone to moss and mildew so moist climates are not good either. It is also not an eco-friendly option.

Metal Roofing

metal-roofProbably the thing that may put some off with metal roofing as a roofing material is how much the installation costs and how noisy it might get with hail or rain. It is also not full proof against strong winds and can get dented and scratched easily. However despite these issues it remains popular as an option for a lot of roofers because it is fire resistant, strong and durable while also being low maintenance and recyclable.

Tar and Gravel or Built Up Roofing (BUR)

tarThis is an old system for commercial roofing and has proven to be very reliable for flat roofs. Many piles of roofing felt use bitumen to laminate them together. While the cost is higher than other roofing options it is a favorite of not just contractors but also architects, owners of buildings, manufacturers and engineers. It can last up to 150 years, it can waterproof, it is durable and thick and can be repaired and maintained to extend its life. But moving the materials needed can be costly, it weighs a lot and it s not suitable for places that reach high temperatures.

Modified Bitumen Roofing

Similar to BUR but this is asphalt-based and can be used on flat roofs or low sloping ones. There are more design options with this roofing than with BUR too. It is just as uplift and fire resistant but on flat roofing that gets a lot of heavy rain it can become submerged and with just one layer this means water could seep through if there is even just a tiny opening.


Single Ply Roofing

single-plySeveral layers of installation and barriers are mechanically fastened together to create single ply roofing systems. They are thin, lightweight and easy to apply and are recyclable too. But this is an expensive option and if people are going to have to walk on it, it will need a protective layer added to its surface.

There are a lot of things to think about when choosing commercial roofing materials, your climate and weather conditions, longevity, ease of maintenance, cost, easy to install and so on. Make sure you choose a material that meets your needs and be sure to consult with a roofing expert who can offer you their experience and knowledge to help make the right choice for you.
