EPDM For Flat Roofs

EPDM, or ethylene propylene diene monomer, is a very popular, low cost roofing material that is suitable for flat or low slope roofs. Because it is a single layer rather than multiple layers laminated together, it is not expensive and is relatively easy to maintain. It can either be installed fully cured or can be left to naturally cure after installation.

It can be attached to the roof with adhesives, mechanically attached to decking or under layer with fasteners, or attached only to the perimeters. In the latter case, the seams are sealed with tape, and then the entire roof is covered with a layer of rock. A professional Ocean County roofing contractor can offer expert advice on the best solution for any given roof.

EPDM roofs have a number of significant advantages. They are resistant to hail damage and other forms of weather damage. They are also UV resistant, and pliability makes this type of roof resistant to cracking and brittleness. Best of all, if properly installed and maintained, an EPDM roof can last for up to 25 years. As with any roof, an inspection at least twice a year is essential to identify any problems at an early stage.

An EPDM roof can be coated with a reflective material to create a cool roof, which reduces the amount and rate of absorption of the sun’s energy.

When a good insulation barrier is installed as well, the energy savings can be substantial. Because it is exposed over a large area, an EPDM roof provides an excellent platform for a solar energy system.

For the ultimate green roof, EPDM provides an excellent base for a garden roof, if it is installed and sealed properly. It is important that the roof structure can support the additional weight, however, which can be significant. Subject to these provisions, and EPDM can provide a base for garden beds or even a lawn. An added benefit of doing this is that the layer of soil will act as further insulation.

When resurfacing a flat or low slope roof, EPDM is one of the more attractive options available due to its low cost, ease of installation and maintenance, versatility and long lifespan. Coupling it with an energy reduction measure, which can be an inexpensive reflective coating or a sophisticated solar energy system, makes it an even more attractive proposition. It should be near the top of any list for a new flat roof design. A roofing contractor from Fortified Roofing of Ocean County NJ can answer your questions about new roofs or roof repairs.
