EPDM Roofing

EPDM is a high-performance synthetic rubber membrane that is resistant to tear, puncture, impact, and normal roof traffic. It can accommodate structural movement and remains pliable across wide temperature variations. For new roofs or reroofing, EPDM is the popular and economical solution over a variety of roof decking and insulation materials.

Single-ply Roofing Membranes:

Single-ply Roofing Membranes

Single-ply systems are made up of large sheets of various materials–elastomers such as EPDM, and various thermoplastics. As the name implies, only a single layer of this material is used to complete the roof. In general, these materials offer good elasticity and weather resistance.

There are several different techniques for attaching single-ply roofing systems to a roof. Many single-ply roofs are “ballasted,” or anchored by a layer of stone or paver blocks. Others are mechanically attached to a substrate or deck using screws and reinforcement plates. A third option is the “fully adhered” single-ply roof which is completely glued to the roof substrate. Other single-ply roofs can be installed using a combination of methods.

Single-ply roofing systems are generally faster and easier to install than built-up systems. But because a single layer provides all the waterproofing and weather-resistance, installation techniques are more demanding and proper installation is critical.

EPDM (Ethylene Propylene Diene Monomer)

Better known as “rubber” roofing, EPDM membrane offers a host of advantages. EPDM is considered to be the longest lasting membrane roof system and can be installed in several ways; fully adhered, ballasted or mechanically attached. Overall EPDM roofing offers enhanced weatherability, durability and versatility but has greater difficulty withstanding oil and chemical attack.

Modified Bitumen Systems

Modified Bitumen Systems

Modified bitumen roofing systems also use multiple layers of bitumen and reinforcing materials, but various materials, such as polymers, are added to the bitumen to alter some of its properties for greater stability and flexibility in a wide range of temperatures. Modified bitumen roofing systems are very versatile and can be used in most applications with adequate drainage. They are also easily repaired when required.


Thermoplastic Polyolefin single-ply roofing. This roofing material can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are three to four times higher than EPDM roofing systems. This is a popular choice for “Green” building. It is available in white, grey, and black. Using white roof material helps reduce the “heat island effect” and solar heat gain in the building, thus reducing interior energy costs significantly.

Standing Seam Metal

Our expert craftsmen also install and repair all types of Metal Standing Seam Roof coverings in a variety of coated colors, finishes and profiles. We also offer Custom Copper Metal Roofing which is virtually maintenance free and has an ever changing beauty over time.

Low-Slope Roofing Tie In

The Roofing Guys & Siding can handle all of your low-slope roof needs. One of the most difficult installations is the tie-in from one type of roof covering to a low-slope roof. We are experts at solving these issues whether it is a new installation or one that has leaked for years.

Our Approach as You Conduct Business

We understand that customers and staff must have access to your entryway as we work on your roof; therefore, we will devise a plan that will keep the flow of traffic unobstructed whenever possible. We will find a way to stay out of the flow of traffic and allow you to continue business as usual. The Roofing Guys & Siding will keep you informed about any move we make. We value your input as to what makes your business run more smoothly.

Our belief in customer satisfaction and our workmanship warranty means that you will never face this problem. Should an issue arise, we are not going anywhere, we’ve been here for sixteen years and we will be there for you in the future to make it right.
