EPDM rubber roofing is a strong and durable choice for flat commercial roofs. It’s made from Ethylene Propylene Diene Monomer (EPDM), a material that protects roofs from leaks and damage. It’s popular because it can last up to 60 years if you take good care of it. If you’re wondering how to install EPDM roofing, first make sure you clean the roof. The roof deck has to be dry and smooth for the installation process, and then a drip edge has to be added. This helps direct water away from the roof. Now lay down the EPDM Membrane. You must let it sit for an hour before gluing it down), and seal the edges to prevent moisture from getting inside. If you find the installation difficult or prefer not to do it yourself, you can always get help from roofing experts.
5 Step To Install EPDM Roofing
Here are detailed steps to help you with the installation process.
1. Preparing For Installation
EPDM roofing can be installed on different surfaces, but timber decking like plywood or OSB boards is often preferred. It helps ensure better performance and stability. Single-ply roofing systems are easy to install using methods like ballasted systems, mechanical fasteners, or adhesives.
2. Clean the Roof Deck
Start the EPDM roofing installation process by cleaning the roof deck, whether it’s plywood or OSB board. Remove any oil, dirt, or grime from the surface. Sand down any sharp edges to make sure the surface is smooth. It’s important to make sure there’s no moisture on the deck, as this can cause problems when applying the adhesive. You can also add a layer of insulation to prevent water vapor from forming beneath the roofing. Make sure to follow guidelines for proper installation.
3. Add Drip Edge and Batten
Proper drainage is important for any roofing installation. Once the deck is ready, install the drip batten around the edges of the roof. This helps direct water towards the gutters or storage systems. After installing the batten, add a drip edge, making sure it lines up with the top of the batten. This will prevent water from collecting on the roof and causing damage.
4. Install the EPDM Membrane
The next step for EPDM roofing installation involves covering the roof with the EPDM membrane.
- Carefully unroll the membrane and place it over the roof.
- Let it sit for about one hour to settle in place.
- After waiting, roll back the membrane and apply bonding adhesive to the roof decking.
- Be sure to leave about a 6-inch gap around the edges.
- Once the adhesive is applied, reattach the membrane and press it down to remove any air bubbles and ensure a strong bond.
5. Finishing Touches
You must focus more on the edges of the roof, apply the adhesive carefully around it, and seal it with pressure-sensitive adhesive. If there are any chimneys or vents, ensure you seal them properly using watertight seals and trim any excess membrane. This sums up the process!
What do you put under EPDM?
You usually put insulation boards or a protective underlayment under EPDM to create a smooth surface. This helps improve energy efficiency by reducing heat transfer through the roof. Additionally, it protects the EPDM membrane from potential damage caused by any sharp or uneven surfaces on the roof deck.
Does EPDM have to be glued down?
Yes, EPDM is typically glued down to make sure it is secure and also to prevent any movements. Proper adhesion helps to eliminate air pockets that could compromise the membrane’s effectiveness. It’s important to use an EPDM-approved adhesive to ensure long-lasting durability and a watertight seal.
Can we install EPDM on plywood?
Yes, EPDM can be installed on plywood, but it’s best first to ensure the surface is clean and smooth. Any debris or imperfections should be sanded down to prevent damage to the membrane. Additionally, applying a primer or protective underlayment can help enhance adhesion and provide extra protection for the plywood beneath.
Does cement stick to EPDM?
No, cement doesn’t stick well to EPDM. EPDM is designed to be waterproof and smooth, so cement can’t bond to it properly. Instead, specialized adhesives or sealants should be used when working with EPDM to ensure a secure and durable connection. Using cement may lead to cracks or leaks, compromising the integrity of the waterproofing system.
Conclusion
To sum up, installing EPDM roofing is simple if you follow the right steps. First, clean and smooth the roof deck, and add insulation if needed. Put on the drip edge and batten for good drainage, then cover the roof with the EPDM membrane using adhesive. Finally, secure the edges with pressure-sensitive flashing and seal any holes like vents or chimneys.
