Traditionally, flat roofs were made from mineral felt that was covered by a layer of stone or gravel chippings for protection against the sun rays. These types of roofs had many disadvantages, particularly a tendency to crack or to blister when exposed to UV rays and a susceptibility to mold and algae damage.
Newer flat roofs are typically made up of a highly resilient rubber membrane known in the market as Ethylene Propylene Diene Monomer (EPDM) that solves most of the problems associated with felt roofing. Here is a look at the benefits of modern rubber roofing to help you determine whether it would suit your home.
Durable and effective
EPDM usually comprises of a single piece of high-tech PVC rubber material, allowing the roof to remain intact for longer periods than traditional flat roof structures. The rubber material is also very resilient and can withstand high winds, pounding rain and cyclical membrane fatigue without severe degradation. Additionally, the roofing is also able to expand and contract as temperatures fluctuate, making it resistant to cracking, unlike traditional felt roofs.
Modern rubber roofs are also very resistant to UV damage, and can and tend to be retardant to fire and extreme heat, making them ideal to areas prone to forest fires or scorching temperatures. The roofing material also has superior heat reflecting qualities, allowing the home to remain cool even during the hottest of days.
Ease of installation and maintenance
EPDM offers a pretty fast and practical installation process, as there are no torches or hot bitumen required to hold the roof in place as is the case with felt roofing. The large rolls used are also lightweight, while the flat design allows for the membranes to be installed much faster.
Another major advantage of a rubber roof is its ease of maintenance and repair. Easy accessibility due to the compact, level design means that repairmen are able to locate and seal any leaks faster than they would on angled roof designs, while the wide rubber rolls used allow for most roofs to be covered with a single membrane, eliminating the need for sealing joints and seams that would cause leaks further down the road.
Felt roofs offer a maintenance challenge where gravel or stone chippings are washed down into gutters and hoppers, causing blockages. There are no stone layers required on a modern flat rubber roof, eliminating such clogging. There are also no issues with mold damage as is the case with traditional flat roofing.
When installed correctly by a certified professional, EPDM can make for energy efficient, durable and low maintenance roofing material that is easy and cheap to install and that solves most problems associated with traditional felt roofs. Contact a company like RTN Roofing Systems to learn more.
