Types of EPDM Roofing Systems

Per our Atlanta-based EPDM roofing installation team, three main types of EPDM membranes are available in the market: reinforced, non-reinforced, and pre-taped. Each class offers unique benefits, depending on the specific needs of your roofing project.

This section will explore the differences between these EPDM membrane types and their respective applications.

Reinforced EPDM Membrane

Reinforced EPDM membrane is stronger and more durable than non-reinforced membranes. It is constructed with a tough polyester reinforcement sandwiched between two robust EPDM membranes. Due to its enhanced durability and puncture resistance, the reinforced EPDM membrane is suitable for mechanically attached and fully adhered roofing systems.

A popular example of a reinforced EPDM membrane is ‘Mule-Hide Standard Reinforced’, designed to offer superior resistance to roof tears, punctures, and wind forces.

Non-Reinforced EPDM Membrane

On the other hand, the non-reinforced EPDM membrane offers increased flexibility and reduced weight, making it easier to install and more cost-efficient. This type of EPDM membrane is suitable for various applications, including low-slope roofs, pond liners, and other waterproofing uses.

However, it is essential to note that non-reinforced EPDM membrane is not as robust as reinforced EPDM membrane and is more susceptible to punctures and tears.

Pre-Taped EPDM Membrane

Pre-taped EPDM membrane is a time-saving option for expediting the installation process. This membrane type comes with pre-applied tape, allowing faster and easier installation in the field. One example of a pre-taped EPDM membrane is ‘Firestone RubberGard EcoWhite EPDM Pre-Taped’, which features factory-installed seam tape, providing a more efficient installation process and reducing labor costs.

The benefits of a pre-taped EPDM membrane include quicker and simpler installation, decreased labor costs, and enhanced water tightness.

However, it is important to note that fully adhered systems require professional installation and can be more expensive due to the cost of adhesive. The installation process for a fully adhered system includes cleaning the surface, applying the adhesive, and laying down the membrane.

Mechanically Fastened System

Mechanically fastened systems are a cost-effective EPDM installation method that uses screws and plates to attach the membrane to the roof structure, followed by sealing the membrane with a special adhesive to guarantee a watertight seal.

To mitigate the potential for fasteners to become loose over time, it is essential to select the appropriate type of fastener and ensure proper installation. This method can be advantageous when the installation is in cold weather conditions.

Ballasted System

A ballasted system is a low-cost EPDM installation method that uses heavy materials, such as gravel or pavers, to hold the membrane in place. This type of flat roof system is loose-laid, meaning the roofing materials, including the insulation and roof membrane, are not affixed to one another or the low-slope roof deck.

Ballasted systems offer energy savings, lower installation costs, and protection from damage caused by ultraviolet light, tree branches, and hail. However, they have higher maintenance costs throughout their lifespan and can be challenging to inspect and repair, as the stones or pavers must be removed to access the roof membrane.

Factors Affecting EPDM Roofing Costs

The cost of EPDM roofing is influenced by various factors, including material and labor costs, installation complexity, roof pitch, accessibility, location, insulation type and thickness, and whether an old roof needs removal.

In this section, we will discuss these factors in more detail and provide you with a better understanding of the costs associated with EPDM roofing installation and replacement.
