One of the aspects which makes flat roofs so appealing for commercial properties is the relatively low installation cost due to the fact that only the lip of the roof can be seen from the pavement. Also the installation process is safer and the end result is a smart, aesthetically pleasing finish. Further to this, once a flat roof has been installed they are easy to maintain. Any repair work can be carried out quickly with minimal disruption.
There are various types of roofing solutions available for commercial buildings. These include; RBM felt (reinforced bituminous membrane), mastic asphalt, liquid, fibreglass and EPDM rubber roofing.
A felt roof is a fantastic option for commercial roofing due to the adaptability of the material to be moulded unproblematically onto any style and sized roofing. Further to this it comes in a range of colours as well as a protective reflective UV layer which can be added at the end. This UV layer works to reflect the sun rays which over turn can cause damage to the roofs surface. Another bonus with a felt roof is that it can withstand heavy footfall and a felt roofing system typically has a 20-year life span before it runs into any problems.
The modern method of laying a felt roof varies greatly from the older methods and produces a sturdier and hard-wearing roof. The felt for the roof comes in rolls and is then moulded to the roofs structure by using a large blow torch. The process normally involves a roofing contractor use felt that contains a 3-layer system. Firstly, a perforated underlay1 is used, next a 2mm underlay is added and finally a thick 4-5 mm cap sheet (which is a felt layer) Further to this, each layer is strengthened with strong polyester weave that has been inserted into the middle of the felt increasing the roof’s robustness. Roofers also strengthen the roof by adding the different layers using a half lap manner. This is where the joints are all as far away from each other as possible.
Asphalt roofing is a great choice for commercial roofing. It is not only reliable, but also hardwearing and easy to mould. It has a proven track record and is often referred to as ‘The King Of Waterproofing”. It is perfect for complex detailing and can be applied to a range of substrates, including wood, metal and concrete. Additionally, asphalt roof maintenance is straightforward making it a stand out option for commercial roofing installations.
It is vital with asphalt roofing to make sure the commercial roofing contractor you use is experienced in the use of mastic asphalt. Asphalt is a highly skilled trade which requires an extensive apprenticeship. If you ensure you hire a roofing contractor with the appropriate asphalt credentials such as being members of 'The Mastic Asphalt Council'2 you can be assured of quality workmanship.
Asphalt roofing requires a specialist mixer to heat asphalt blocks to a temperature of 220 degrees Fahrenheit. Once heated the asphalt becomes malleable and can be poured onto the roof’s substrate. Roofers work in teams with one pouring the molten asphalt and the other spreading it with a float. Once spread across the roofs surface it is sand rubbed, then left to cool off and become hard. Once finished it is often painted with solar reflective paint to protect the asphalt from the UV rays. This also assists in extending the lifespan of flat roofs in mastic asphalt.
Liquid roofing systems are popular roofing systems for commercial use. This is because of the wide array of benefits liquid roofing systems offer. When waterproofing a commercial building using a liquid system you are able to install the product all year round. The only requirement is the temperature is above 0℃. Additionally some liquid systems are waterproofed instantly upon application. Whereas others will be waterproof within 2 hours.
This means you can almost immediately make use of the roof once application is complete. The obvious benefit of this is minimal disruption. This benefit is enhanced as the building below can be left unchanged during the roofing work. The reason for this is liquid systems are cold applied, meaning no naked flames are used during installation. Another benefit of liquid systems is they are ideal for complex detailing, where it can perfectly form around features such as roof lights.
