Rubber Roofing Rolls: EPDM, Principles of Application, Advantages & Disadvantages
What’s first to come into your mind when you face the problem of re-roofing your house? Don’t know what type of roofing material to give preference to? Looking for both low-cost & eco-friendly solution? Pick rubber roofing rolls!
Rubber roofing materials may be applied in sheets, rolls or individual molded roofing shingles, usually made of EPDM (ethylene propylene diene monomer) synthetic rubber. Due to its durability, easy installation and design versatility EPDM is the most popular material for low-slope roofing applications. Simply speaking, EPDM is an elastomer with a wide range of industrial applications, including synthetic rubber roofing membrane, which has the following roofing material advantageous characteristics: membrane fatigue resistance, thermal shock durability, flexibility in low temperatures, and high resistance to weathering, ozone and abrasion. Rolled roofing made from EPDM synthetic rubber is considered to be the most economical and easiest way of roofing a structure. So, how is it applied and what are its main pros & cons?
Principles of Application of Rubber Roofing Rolls
Though individual composite shingles are the most conventional way of roofing one’s house, rolled rubber roofing, which essentially resembles rubber shingles, but is rather thinner and installed in long strips, is also a very popular roofing material among many homeowners. Usually, rolled rubber roofing is used on low-sloped roofs, but sometimes it may be used on roofs of garages, work-sheds, out-buildings, places where aesthetics isn’t of much consideration. This type of roofing material works well for low-sloped roofs, because, due to their angle, they are less visible, and if you have a house with a roof pitch declining 2 inches or less vertically per 12 feet horizontally, it’s perfect for roll roofing.
Rolled Roofing: Advantages & Disadvantages
Despite rolled roofing installing being the easiest way of roofing one’s house, it won’t work for just any situation, because it has its specific purposes as well as its main pros and cons which include the following:
- perfect for covering low-incline roofs;
- easy and quick installation;
- high resistant to rainwater;
- low-cost roofing material (even compared to composite shingles);
- short lifespan (about 5-8 years);
- less attractive than any other roofing material;
- little variety of colors;
- poor resale value.
How to Install Rubber Roofing Rolls: Step-by-Step Guide
Rooftops, exposed to harsh elements, may sooner or later become susceptible to leaks and weather damage, making EPDM rubber roofing the best alternative to standard roofing systems. EPDM rubber roofing is a durable protectant that requires little or no maintenance, provides maximum insulation, and having no joints facilitates the installation, which can be achieved without professional assistance by simply following the steps:
- prepare the roof surface (use high grade roof cleaner to clean it and rinse away any loose debris);
- roll out EPDM rubber (allow rubber to lay out for at least half an hour);
- cut rubber section to the desired size (determine how may rubber sheets you’ll need);
- stir the adhesive (at least 5 minutes) and spread it evenly (fold back each rubber sheet and apply adhesive to the roof surface with a paintbrush);
- bond rubber to the roof (smooth out any bubbles with a paint roller);
- wipe away any remaining adhesive (use a towel to clean adhesive at the seams of rubber sheets);
- seal the rubber together (apply the seam tape and let the rubber dry for at least half an hour).
