Commercial roofing encompasses a wide range of technologies and techniques, which are not common in residential structures. Because of the large size and heavy duty requirements of industrial facilities, their roofs must be suitably sturdy whilst using a minimum of materials in order to keep costs down. In order to meet these requirements, there are a number of materials used such as asphalt, gravel, tar and membranes. The below guide is designed to make you aware of the choices available for commercial roofing. Using this knowledge, you will be armed with all the information you require to choose the most functional roofing option for your needs. Checkout roofing contractor Nampa for more info.
If you have used a road recently, chances are you have encountered asphalt. Although it is most commonly associated with roads, asphalt is also a useful material for roofs, especially those that are flat or which have a very slight incline. As a by-product of oil production, asphalt is widely available and is durable. There are mounting environmental concerns regarding the use of asphalt, but this has not limited its usage. Asphalt for roofing is generally found in the form of shingles. These shingles are very low cost and low maintenance. Whilst asphalt is not the lightest of materials, installation is still a breeze and can be completed quite quickly, even on larger buildings.
Like many people, you may have wondered why a lot of flat roofs on commercial buildings have gravel on them – today you get to find out! On flat roofs, a layer of tar sheeting is usually applied onto the top surface as a means of waterproofing. As you can well imagine whilst being waterproof, this tar sheeting is highly susceptible to degradation by the weather – excessive heat can cause blistering and cracking of the material. In order to protect the tar sheeting, a layer of gravel is spread over the roof. The gravel provides a low cost layer of protection that is also very simple to install. Tar and gravel roofs are among the cheapest options to install and have stood the test of time as a quality choice.
Much like the previous options, membrane roofing is almost exclusively used for the flat style roofs found on industrial buildings. This technique is seen as the modern improvement on the tried and true tar and gravel method. Rather than tar sheeting, a membrane made from synthetic rubber, PVC plastic, or similar materials is used to waterproof the roof of a building. These are either fitted in one continuous sheet, leaving no seams, or as multiple sheets which must be joined using heat to melt the two pieces together. Membranes do not require gravel over the top of them like tar sheeting and are much more efficient to install. In addition to this, they have also been proven to provide a far more reliable and long lasting waterproof seal. This has made membrane roofs a very popular choice for modern industrial buildings.
