What Is EPDM Roofing?

EPDM is a type of roofing material that is used for flat roofing systems. Homeowners may not choose it for aesthetic purposes, but it’s practical and durable, and it will certainly get the job done in terms of protecting your property from the elements. It can be used for both residential and commercial structures that have low slopes.

EPDM flat roofs are designed to last about 25-30 years. They are flexible, lightweight, and have fire resistance to wind, thermal shock, UV radiation, hail, extreme temperatures, and more.

EPDM Flat Roof Installation

EPDM Flat Roof Installation

EPDM roofing installation is a very easy process and it is widely used nowadays. EPDM roofing is a type of roofing that is installed with large sheets.

The EPDM roofing process is a type of process which required fewer laborers and it does not require too much-skilled labor.

This type of method is a “fully adhered” method where an adhesive material is used to bond together. The EPDM roofing process is a step-by-step process that provides rubber roofing to protect your flat roof.

Some items that are required to install the EPDM rubber roofing are below,

  1. EPDM membrane
  2. Paint roller
  3. Adhesives (for bonding purposes)
  4. Utility knife or scissors
  5. Gloves and eye protection
  6. Push broom

Cost of EPDM Flat Roof

Cost of EPDM Flat Roof

The rubber roofing cost, particularly for epdm roofing cost per square foot, varies from one range to another range because of the availability of raw materials and skilled laborers.

On a typical flat roof, the install cost of an EPDM flat roof is expected to vary from $6.50 to $12.50 per square foot. Or for the low slope roof replacement, it varies from $9750 to $18750 for 1500 square feet.

The flat roof cost also depends on the number of penetrations, the number of layers of insulation, also the existing roof removing cost, and the cost depending on tear-off may be lower or higher.

And Other costs affecting factors are accessibility, overall roof difficulty, and the location of the project. For this above reason, we can say this flat roof system also increases the total cost of the project.

How to Install EPDM Rubber Roofing?

How to Install EPDM Rubber Roofing?

The process of how to install epdm roofing, specifically epdm roof installation, is straightforward and it is widely used nowadays.

EPDM rubber roofing is a type of roofing that is installed with large sheets. EPDM rubber roofing process is a step-by-step process that provides rubber roofing to protect your flat roof.

This type of method is a “fully adhered” method where an adhesive material is used to bond together. There are have many steeps and required experience to avoid many mistakes that cause damage to the roof.

The steeps are showing below.

  • Prepare the roof deck.
  • Add a drip edge and drip batten.
  • Install the rubber membrane.
  • Apply the finishing touches.

1. Prepare the Roof Deck

At first, we have to prepare the roof deck by cleaning the deck from the grime or oil and also cleaning any sharp edges of OSB board or plywood from the roof deck.

The adhesive, can lead to a problem with the moisture with a little amount, for this reason at first you should be ensuring that everything is totally dry then you can start the installation process.

If over an existing roof you want to install EPDM then at first you should be cover it with a clean OSB board or sanded plywood to protect the membrane create a barrier and cover it.

For the roof decking if you want directly apply the EPDM then a layer of insulation should be added to prevent the water vapor problems.

2. Add a Drip Edge and Drip Batten

After ready the roof deck we will need to install a drip edge with the batten aligning the curved top.

Before installing the drip edge, into the fascia the drip batten is installed around the roof and into the gutter system to guide drain water extend the decking.

A drip edge and drip batten system can prevent erosion around the foundation.

3. Install the Rubber Membrane

To cover the roof edge and exterior walls completely with a thick overhang we will need enough EPDM membrane. After the drip edge is installed, the rubber membranes are unrolled in the place where they will be installed.

When you applied the rubber membrane to the bonding adhesive for up to half hours it will be relaxed in a place because when it is applied it will not create any problem.

4. Apply the Finishing Touches

The finishing touches may be small on the final edges, but care to do right and they take time. Around the edge of the border, the adhesive should be applied.

By using pressure-sensitive flashing the corners you will need to be sealed. For vents to create watertight seals use flashing and another roof preventing things.

To prevent the entry of moisture from the membrane all edge is the seal by the silicon sealant. After that by trimming you can remove the extra membrane from the roof.
