In this article

    EPDM stands for (Ethylene Propylene Diene Monomer). EPDM rubber is a roofing solution that is durable and weather resistant. It is a synthetic roofing material that is mostly used on flat roofs. EPDM rubber roofing is made from a mix of ethylene, propylene and diene monomers, hence the name sake of EPDM. These materials offer exceptional resistance to UV rays and any temperature fluctuations. EPDM rubber roofing is well known for its long life span, durability and the minimal maintenance it requires. It is a flexible and eco-friendly option for roofing solutions on your property that can really be put to the test by all manner of weather conditions and pass with flying colours. 

    Why Choose EPDM for Your Roofing Needs?

    Choosing EPDM rubber roofing for your home / property is a decision that should be seriously considered for several reasons! Some of these reasons include:

    • Durability: the EPDM rubber roofing material is a highly durable material and it also has a very long lifespan usually lasting over 50 years! Something we say here at Evesham Trade Centre [GM Roofing] is “you only need a rubber roof once!”. If you look after your rubber roof properly and conduct maintenance on it, it can last a lifetime and you should never need to replace it! An EPDM rubber roof can withstand harsh weather conditions and outside temperatures including extreme weather conditions without the materials deteriorating.
    • Weather Resistance: EPDM is also known for exceptional weather resistant properties. The EPDM rubber roofing materials are resistant to UV radiation, harsh rain, snow and hail as well as winds and harsh sunlight. The EPDM will remain intact and protect your home.
    • Low Maintenance: This roofing material needs very minimal maintenance and reduces the long-term costs of the upkeep to your roof. To maintain your roof it will require occasional cleaning and inspections to make sure that any issues that may arise are caught early and easily fixed. The occasional cleaning and rare inspections are really all that is needed to maintain your EPDM rubber roofing and keep it performing properly for your home.
    • Cost-Effectiveness: EPDM rubber roofing is definitely one of the more cost effective roofing materials. While the initial cost of the roofing may be more expensive than you are expecting, it does eliminate the long-term costs of roofing upkeep. The longer lifespan and these reduced upkeep costs makes an EPDM rubber roof a great choice for long term investments into your home.
    • Energy Efficiency: EPDM roofing materials are often available in white or available with a reflective coating on them. These colours or coatings can help to reduce the energy costs by reducing cooling costs in your home, this is done when reflecting the sunlight and heat away from your home, ultimately lowering your energy bills.
    • Versatility: EPDM rubber roofing materials are extremely versatile and can be used on many different architectural styles and different types of buildings. These can vary from residential homes, commercial buildings and industrial properties. EPDM rubber roofing is suitable for new installations or roofing replacements, making it a popular choice for many different projects and property renovations.

    The Benefits of EPDM Rubber Roofing

    EPDM rubber roofing offers you as the property’s owner many benefits, which help to boost its popularity as a roofing material. Some of the key advantages of EPDM rubber roofing include:

    • Durability: It’s proven track record of long-term durability and performance. It is very durable and can withstand the harsher weather conditions such as UV radiation, extreme temperatures and fluctuations in weather conditions. 
    • Weather resistance: This roofing material is highly resistant to UV rays, rain, snow, hail and sleet as well as harsh winds. Even facing these possible harsh weather conditions your EPDM rubber roof will uphold its features and integrity and continues to protect your property in these weather conditions.
    • Longer Lifespan: When you have your EPDM rubber roofing materials installed properly and professionally and you maintain your roofing the materials can last for around 30 years+ some cases exceeding 50 years of durability! This longevity of the materials and the installation can save you money in the long term on any roofing replacements and roofing upgrades in the future.
    • Quick Installation: EPDM usually has a quick installation time and can help you to reduce costs on labour and minimise disruptions to your property and schedule.
    • Flexibility: The material in EPDM rubber roofing has flexibility which allows the material to adapt to a building’s movements and settlements over time without cracking and breaking, ensuring that the roofing remains intact.
    • Proven Performance: EPDM has a history of success in its use in roofing applications. Millions of square feet of EPDM rubber roofing are installed worldwide each year demonstrating its reliability.
    • Eco-Friendliness: EPDM is a recyclable roofing material that doesn’t release harmful chemicals and substances which makes it an environmentally friendly material and therefore an environmentally friendly roofing choice.

    How to Install EPDM Rubber Roofing

    It is best to leave installing EPDM rubber roofing to trained professionals, such as our teams here at Evesham Trade Centre. This is due to the complexity of the installation and the need for the precise measurements and techniques to use when installing the roofing.

    Materials and tools [recommended]:

    • EPDM membrane (this can be purchased at Evesham Trade Centre or the Cotswolds Home Improvements Supercentre)
    • Adhesive or seam tape
    • Primer
    • Roofing membrane cleaner
    • Seam roller
    • Utility knife
    • Rollers for pressing membrane down
    • Flashing and sealant (edges)
    • Metal termination bars and screws
    • Screwdriver / drill
    • Roofing nails

    Step 1: Prepare the Roof

    • Ensure that the roof deck is clean, clear, dry and free from debris. Repair any damages and fix any leaks or rotting wood you may encounter.
    • Fit insulation boards and make sure they are securely fastened down.
    • Apply a primer to the cleaned roof deck and allow it to dry. [primer helps to ensure a bond between the EPDM and the roof deck]

    Step 2: Measure and Cut the EPDM

    • Measure the roof's dimensions accurately. [allow for overhang usually 3-6 inches]
    • Roll out the EPDM and cut to size. [add overhang]

    Step 3: Apply Adhesive / Seam Tape

    • For a fully adhered system, apply adhesive to the roof deck using a roller or a brush.
    • Carefully lay the EPDM rubber onto the adhesive, ensuring it is properly aligned and free of wrinkles.

    Step 4: Seam Sealing

    • If you are using seam tape, overlap the edges of the adjacent EPDM sheets by several inches.
    • Apply seam primer to the overlap area, and press the seam tape into place. Use a seam roller to secure the bond.

    Step 5: Securing the Edges

    • Install metal termination bars along the roof’s edges and secure them using screws.
    • Apply flashing and sealant around penetrations [pipes, vents etc] to ensure a watertight seal.

    Step 6: Trim Excess

    • Trim the excess EPDM material from the edges.

    Step 7: Check Adhesion

    • Carefully inspect the installation to ensure proper adhesion, no wrinkles, bubbles or imperfections.

    Step 8: Final Inspection

    • Inspect the entire roof for any defects or issues.
    • Clean the EPDM surface to remove dust and debris.

    Remember that EPDM rubber roofing installations require precise measurements, proper adhesive and crucial attention to detail. If you're not experienced in roofing, it is highly recommended to hire a professional to do this installation for you to ensure it is done correctly and to prevent any damage or leaks to your home which could cost you more money!

    EPDM vs Other Roofing Materials

    EPDM rubber roofing is just one option that is available for roofing materials for residential and commercial buildings. To make a more informed choice you can compare EPDM with other common roofing materials, here are some comparisons you can consider with EPDM:

    1. EPDM vs Asphalt Shingles:
      1. EPDM: a single ply rubber roofing material known for durability and resistance to UV rays, common for flat roofs.
      2. Asphalt Shingles: widely used for more sloped roofs. They are cost effective but have a shorter lifespan than EPDM. They may need more maintenance, more often and are less suitable for flat roofs.
    2. EPDM vs Metal Roofing:
      1. EPDM: flexible and well suited for flat roofs. Durable, energy efficient and resistance to weathering.
      2. Metal Roofing: versatile and can be used on sloped or steep roofs. Also highly durable and resistant to fire, reflecting heat well too. It can be a noisier option especially in rain or hailstorms.
    3. EPDM vs PVC Roofing:
      1. EPDM: highly resistant to weathering and UV radiation. Synthetic rubber material making it a flexible and durable option.
      2. PVC: also a singly ply membrane roofing option that offers great UV resistance. It is known for having heat welded seams and high energy efficiency.
    4. EPDM vs TPO Roofing:
      1. EPDM: EPDM is a synthetic rubber material with strong longevity and resistance to UV rays. Less reflective than TPO, however it is still energy efficient.
      2. TPO: TPO roofing is also a single ply membrane, it is thermoplastic. TPO is known for energy efficiency and its white reflective surface. Often used for mainly commercial and industrial properties.

    Common Problems and Solutions with EPDM Roofing

    EPDM rubber roofing does have many advantages but like any roofing materials you can encounter issues over time. Here are some common problems you may face with an EPDM rubber roof and the solutions for these problems:

    Leaking Seams:

    Punctures and Tears: 

    PROBLEM: Sharp objects, heavy debris or increased foot traffic on your EPDM rubber roof can cause punctures or tears in the membrane which can lead to leaks.

    SOLUTION: Patch or repair punctures and or tears with an EPDM repair kit or contact your installers for warranty/ guarantee protections.

    Neglected Drainage Issues:

    PROBLEM: Poor drainage on a flat roof can lead to pooling water which can accelerate wear and tear on your EPDM membrane.

    SOLUTION: Ensuring proper drainage by keeping gutters, downspouts and guttering clean, clear and free of any debris. This can improve the drainage and reduce pooling. You can also do a drainage redesign if you need to, to prevent more pooling and damage to your membrane.

    PROBLEM: Neglecting routine inspections and maintenance can lead to more significant issues over time.

    SOLUTION: Schedule regular maintenance inspections to identify if there are any problems or weak spots in your roofing membrane early and fix the issue before it becomes a problem. Cleaning the roof’s surface and removing debris can also help to ensure the roof’s promoted longevity.
