What Are the Best Materials for Commercial Roofing?

If you are planning to build a new warehouse or factory, you will be thinking about all the aspects of the build, particularly the roof, which is a critical component of any structure. There are numerous materials that can be used for commercial roofing, and here is a list to help you make the right choice when designing your commercial build.

  • Metal Roofing – Here in Australia, aluminium or galvanised steel roofing is definitely the most popular of all the roofing materials on offer, and for good reason, as a metal roof is strong, durable and easy to maintain. Most industrial roofing in Perth uses corrugated aluminium sheeting that is fastened to steel framework and sealed with silicone, which is both cost-effective and appealing to the eye. The metal is also used for cladding, and you only have to drive around a few industrial zones to see how common metal roofing is.

  • EPDM Rubber Roofing – The technical term is ethylene propylene diene monomer (EPDM), but it is known simply as rubber roofing, which has a lifespan of some 20 years. This is one of the cheapest forms of commercial roofing, yet it is durable and watertight, rarely requiring repairs, and once the roof is complete, there’s little maintenance, only cleaning out the guttering.

  • TPO Roofing – Thermoplastic polyolefin roofing, or TPO is also very cost-effective, and thanks to its white colour it reflects the heat, keeping the interior cool during the hot summers. It can be fastened to the existing roof material or with the use of a special industrial adhesive, which makes for a strong seal, and with heat welded seams, there are lo leaks from the joints, which always used to be a problem with composite roofing.

  • PVC Roofing – Polyvinyl Chloride is another popular roof composite, which uses two layers, with a layer of polyester in between, and there are additives to make the sheeting UV stable. The material is also fire and chemical resistant, making it ideal for industrial use, and with heat welded seams, PVC roofing is completely waterproof.

  • SPF – A spray polyurethane foam that quickly becomes solid after application does provide a watertight covering, and the material expends to around 30 times its normal size after application. The expansion ensures there are no leaks, and with a little maintenance, an SPF roof could last as long as 40 years.

  • Asphalt Rolled Roofing – Traditionally the roofing material of choice many years ago, the asphalt is rolled onto the roof using heat to create seams, and while this is an inexpensive solution, an asphalt rolled roof will last around 10 years, and there are other solutions that offer a much longer lifespan.

  • Acrylic Roofing – Acrylic roofing is often a choice when an existing roof requires resurfacing, as it is inexpensive and with 3 coats; a base primer, a second coat and a sealant, the end result is a very durable roof that will require very little maintenance. This type of roofing can be installed on any substrate, and it is predicted to become of the most popular roofing choices for businesses.

Whatever material you choose, it is important that it is professionally installed, which will give you a long warranty and many years of trouble-free use.
