It is fairly obvious that the roof of any commercial building is extremely important. Over the years, the components used to develop and secure a roof have improved, as have their chemical composition. EPDM is basically a synthetic rubber that is highly durable. It is a type of roofing membrane that is mostly used today on buildings with a low slope, both in the United States and abroad. The two main components of this variety of rubber are ethylene and propylene. Both are derived from oil and natural gas, and white and black are the available colors. EPDM is sold in various widths, and these can range from 7.5 feet up to fifty feet. It also comes in two different thicknesses, 45 and 60 mils, depending on the particular roof that it is going to be used on. The rubber itself can be installed in one of three different ways. It can be fully adhered, ballasted, or attached to the roof mechanically. The seams of the roofing system would then be sealed with either a liquid adhesive, or a specially formulated tape.
The Effectiveness of EPDM
With all of the various roofing components in use today, many might wonder why EPDM is the best choice for them. To begin, it has been used on low-slope roofs for more than 40 yeas, and it is now the top choice of roofing professionals, engineers, architects, and contractors that are either installing a new roof, or replacing an existing one. EPDM has consistently been found to perform well under adverse conditions. It holds up even in the most difficult of environments, and has proven itself to have the longest average service life of any roofing component in the industry today.
EPDM is proven to be able to withstand hail, and it is has a resistance to cyclical membrane fatigue. The material itself is also resistant to weathering and abrasion, while remaining flexible in low temperatures. It is also resistant to extreme heat and fire, while possessing a thermal shock durability that cannot be beaten. Finally, it is noted that EPDM is resistant to radiation. The fact that is highly resistant to wind damage is another reason that many roofing professionals choose to only work with EPDM rubber.
Cost Effectiveness of EPDM Rubber
While it is true that actual installation costs will vary depending on the type of commercial building one is talking about, it can be stated with reasonable confidence that EPDM roofing systems offer the most economic value. This is in relation to commercial buildings with a roof that has a low slope. There simply is not a better value on the market that protects your roof with as much precision as EPDM.
EPDM that is ballasted traditionally offers the lowest per square foot cost for installation. Mechanically fastened or fully adhered systems might come in a bit more expensive, but they still provide an excellent value. The EPDM system also enables easy repairs and modifications to the roof itself over the years, so any commercial building owner would be wise to consider this as the best option.
