EPDM (Ethylene Polypropylene Diene Monomer) is one of the most adaptable rubber roofing materials available. EPDM roofing is a low-cost option for your roofing requirements. Because of its ethylene and polypropylene properties, you may expect this material to survive the elements for almost 50 years. It’s quick and simple to apply, and it offers a long-lasting surface that requires little maintenance over time.

EPDM membrane roofing systems can adhere to a variety of substrates. If you want to keep your old roof covering and replace it with a new waterproof membrane, you’ll need to think about the following:

• Rot – The present roof deck and supporting timbers will need to be removed and replaced if they are rotting. For gluing the new waterproof membrane, OSB3 or external grade plywood are both suitable options.
• 
  Upgrade Insulation – While you’re working on your roof, it’s a good idea to put in some freshly heated deck insulation. If the current roof deck is in good condition, the previous waterproof layer, such as felt, can usually be kept in place while the new insulation is bonded over the top with PU adhesive or mechanically attached with screws and washers. The insulation can then be attached to the new waterproof membrane.

How to Install an EPDM Rubber Roofing

EPDM rubber roofing is one of the best types of rubber roofing since it is easy to install. There’s no need to hire a professional if you’re handy with your hands. EPDM can be installed using the steps outlined below

Cleaning of the Surface

Starting with a clean surface is the key to understanding how to install EPDM roofing. This entails clearing the area of all dirt, trash, grease, and other impurities. In addition, the surface must be fully dry. Existing coverings, such as asphalt layers, must be removed.

It’s always advisable to seek a professional for help with business roofs that have drainage or ponding issues. Installing a new EPDM on a roof that is defective, inadequately leveled, or damaged will not improve the situation. Using high-grade moisture-resistant OSB panels, experts can repair or re-level the roof surface.

Pre-Installation Tasks

The next step is to measure and mark the project area using chalk or a pencil to keep sheets exactly straight and reduce the possibility of bubbles or wrinkles. A roof needs enough EPDM membrane to entirely cover it, as well as a large overhang to protect the nearby walls and roof edge. You should also install the drip batten and drip back trim at the roof’s edge at this time to channel rainwater over the gutter.

EPDM Sheet Preparation

You’ll need to prepare the sheets whenever you’re ready to start working with your EPDM rolls. Because of EPDM’s versatility, many projects can be completed with a single, continuous layer up to 50 feet wide. We recommend contacting our pros for assistance if your business roof demands a greater size. This is because one of the most common sources of leaks and moisture damage is poorly installed seams.

EPDM Sheet Application

The EPDM sheet is ready for installation when it has been fully rested. Working with half a sheet at a time is ideal in most cases. This is how to properly install EPDM roofing. Begin from the wall’s edge and work your way up to the roof’s edge. If you’re using water-based glue, apply it to the roof with a paint roller in three- or four-foot chunks across the leading edge.

Roll the EPDM forward while the glue is still wet, and then begin the next section. The way bonded adhesive works is a little different. It must be applied to the roof surface as well as the membrane. This product enables you to deal with larger parts that require 5–20 minutes to dry before the membrane can be extended.

Brushing

It’s pertinent to brush the EPDM membrane with a large shop broom right after it’s been rolled out. This is intended to reduce bubbles and strengthen the connection. Continue in the same manner as you did during installation.

Now that you have applied half of the membrane, it’s time to move on to the other half. Follow the preceding EPDM roofing glue and brushing installation instructions, leaving a thin border at the roof’s edge for the finishing phase.

Final Words

You must add some finishing touches when you are done. You can decide to remove the excess membrane, apply bonded adhesive to roof and wall edges, and even seal roof corners. These finishing touches, when done correctly, make your roof look gorgeous and able to withstand any type of bad weather for decades.
