A Further Look At Epdm

The fundamental characteristics of EPDM membrane are it is black and rubber. It is understood to be very flexible. Though that is with regards to the vulcanized form of the material. Its rarely referenced as such because its the typical form.

Non-vulcanized is less flexible and is referenced as the form of the material used for flashing or sealing seams between roof and penetrations from extruding pipes or other such roofing features.

While black is easily the most common color, EPDM does sell with a white surface, or laminated top. This is done to compete with the TPO and PVC options and to achieve the CoolRoof ratings and/or energy-efficiency performance effects. Yet, those other materials are vastly superior in reflecting UV rays, whereas EPDM either is not as efficient, or its a matter of an ongoing debate.

Note that EPDM liquid roof coatings are a different product from EPDM rubber membranes.

Being black though has its benefits, and is said to block UV rays, or absorb heat, which in colder climates is desired. If for any reason, black doesnt appeal to you, using an acrylic paint on the surface does allow you to have unlimited color options.

EPDM is known to require ongoing maintenance with the seams due to how its seams hold up or dry out and become compromised over time. Resealing and re-coating are the most viable options and really do extend the life of the roof.

Factors Affecting Rubber Roofing Costs

Most rubber roofs are unique as they are cut to fit your exact roof, whatever the shape. As such, it can be difficult to estimate the rubber roofing cost accurately. To budget for rubber roof installation, it is a good idea to take the following into account:

  • Size of roof: The larger your roof, the greater the price of installation will be.
  • Type of rubber roof: With several different options such as EPDM, the cost of rubber roofing will vary between each type.
  • Ease of access: If your roof is an odd shape, or difficult to access, this will push up the price.
  • Height of roof: Higher roofs come with added danger and risk of injury so will therefore be more expensive to work on.
  • Location: The labour cost that your tradesperson charges will be higher in places like London and the South East due to higher living costs.
  • Adding roof slope to aid drainage: It is possible to alter the slope of a roof to help rainwater drain off, although this will be charged at a premium.
  • Adding insulation: It is wise to ensure your roof is properly insulated to make your home more energy-efficient.
  • Any repairs to timber required: If the timber of your roof is damaged from moisture or flying debris, it is necessary to fix this before adding your rubber roof.

The Different Types Of Flat Roofing

There are four types of used in the Boston area.

Perhaps the most well known type of flat top roofing is called the built-up roof. This type of roofing consist primarily of several layers of materials that are laid down on top of each other. The material used can be quite varied, including everything from hot tar, gravel, fiberglass and even roofing felt. One of the significant advantages of this type of roofing is that it is fire-resistant, but because of the smelly nature of the hot tar used, using it on buildings that are regularly occupied isnt always the best option. This choice can be a very economical one, with the cost per square foot of installation being somewhere between $3.50 and $7.00.

Keep in mind though, EPDM membrane roofs arent the only choice available if youre considering a membrane style roofing system. Another choice is a PVC membrane roof. Although it is a bit more expensive at $7.00 to $11.00 per square foot due to the increased amount of labor, it does have some significant advantages. One of the most notable is the sheer overall durability of the roofing system. Another is the fact that it is one of the most environmentally friendly options on the market today. Its also resistant to many chemicals, moisture, wind, fire and even some chemicals. As you can imagine, a roof made from this material has a significant chance of surviving here in Massachusetts.

The special design of rubber roofing allows it to go on flat roofs whereas the asphalt roof is suitable for sloped roofs.
