Commercial roofing needs to withstand the elements, which include wind, rain, and heat. When choosing your commercial roof material, it is important to take into account all aspects of the material’s durability, longevity, appearance, weight bearing, and if it can be shaped to the design you have in mind.There are a variety of materials that can be used for commercial roofing. Tried and true metal roofs come in with the best longevity lasting anywhere from 40-60 years. Slate roofs both come in many colors and can also change colors due to weathering. They also improve insulation to the building and are planted over waterproof roof membranes. These flat roofs covered with vegetation can extend your roof life by protecting the membrane. These come from various types of pines, cedar, redwood, and cypress trees. These roofs are a great way to conserve energy and have the potential to increase your roof’s lifetime. While the initial durability of the material is listed as around 25 years or more, this is still new and it could be much longer, there just isn’t enough information to tell yet. Solar roofs are a newer design but come with the benefit of solar energy. 8) Clay/Concrete (25 years)ĭensity of these roofs vary from time and temperature heated, which results in many styles, colors, and finishes that come in clay and concrete roofs. These roofs are popular because of their low price with the combination of high durability. TPO stands for Thermoplastic Roofing and these roofs are highly energy efficient, and they have high resistance to damage including fire, chemical, punctures, and winds. These roofs are often in the form of shingles, commonly found on residential housing. A large advantage of this type of material is that it makes a seamless roof, but unfortunately, converting silicon to a spray is not a cheap endeavor which makes this material pricy. The roof is built from converting silicon to a spray and then literally spraying it on. Silicon is a great material that is also referred to as a spray-on roof. The PVC is a great choice for durability but can also be quite expensive due to its longevity and strength. These roofs consist of thermoplastic material that feature seams that are heat welded, making it incredibly strong with a minimum breaking point of 300 lbs/inch. The PVC style is potentially the most popular flat roof material as these roofs are quite strong and durable. The large benefit to these roofs is that they can hold a lot of weight and allow for heavier traffic on the roof however, the downside along with this is that there needs to be great stability to hold the roof. The build-up roof, or the tar & gravel roof, includes piles of alternating layers of bitumen (which is either coal, tar, asphalt or some sort of sealant) with the other layers being made of gravel or other similar materials. Like the EPDM, the modified Bitumen also absorbs heat rapidly. This is a multi-ply roofing material that can be hard to install but once it has been, the building benefits from its multiply layer structure. EPDM is often one of the most popular roofing choices, and it absorbs heat quite easily which can increase utilities on the building. While EPDM has a shorter durability than other materials, the benefit of this material is that it is quite affordable. The first on our list is EPDM, which is known in the industry as the rubber roof. For material you may not be familiar with, we have also included facts you’ll need to know when considering which type of roof to select so that it fits your requirements for longevity, appearance, weight bearing, durability, and shape. We’ve made a list of 13 types of roofing materials and listed their longevity. While all materials have their benefits and drawbacks, it is important to pick the material that will best fit your needs and match your vision for the building. *NOTE: climate and weather conditions can cause great variance on the actual lifespan of a roof.Ĭhoosing a roof and roofing material is an important step in your building process.
