Starting a career in the roofing industry can be both rewarding and challenging. One of the essential skills you’ll need to master is fitting an EPDM (Ethylene Propylene Diene Monomer) roof. EPDM roofing is popular for its durability, cost-effectiveness, and ease of installation, making it a great choice for beginners. In this guide, we’ll walk you through the process of how to fit EPDM roof. Let’s get started.
What is EPDM Roofing?
EPDM is a type of synthetic rubber roofing membrane widely used in low-slope buildings. It is known for its excellent weather resistance, flexibility, and longevity. EPDM roofs can last up to 50 years with proper maintenance, making them a preferred option for many roofing projects.
Tools and Materials You’ll Need
Before you start, gather the following tools and materials:
- EPDM membrane
- Adhesive (water-based or solvent-based)
- EPDM primer
- Seam tape
- Flashing tape
- Scissors or utility knife
- Measuring tape
- Roller
- Brush or broom
- Caulk gun and EPDM caulk
- Protective gloves and goggles
How to Fit EPDM Roof
Fitting an EPDM roof is a straightforward process if you follow these detailed steps:
Step 1: Prepare the Roof Surface
The first step in fitting an EPDM roof is to prepare the roof surface. Begin by thoroughly cleaning the roof to remove all debris, dirt, and any remnants of old roofing materials. A clean surface is essential for ensuring proper adhesion of the EPDM membrane. Use a broom or a blower to clear the area. Next, inspect the roof deck for any signs of damage or weak spots. Address any issues by repairing or reinforcing the deck to create a stable foundation for the new membrane. Accurate measurements of the roof’s length and width are crucial; measure carefully and add a few extra inches to each side to allow for trimming and adjustments during the installation process.
Step 2: Lay Out the EPDM Membrane
Once the roof surface is prepared, it’s time to lay out the EPDM membrane. Unroll the membrane and allow it to relax for about 30 minutes. This step helps to remove any creases, making the membrane easier to handle.
After the membrane has relaxed, position it on the roof, ensuring it covers the entire surface with an overhang on the edges. Proper placement at this stage is critical for a successful installation, so take your time to adjust the membrane as needed to ensure full coverage.
Step 3: Apply the Adhesive
Applying adhesive is a critical step in securing the EPDM membrane to the roof surface. Depending on the manufacturer’s recommendations, you can use either water-based or solvent-based adhesive. Begin by folding back one half of the membrane lengthwise to expose the roof surface. Using a roller or brush, apply a generous amount of adhesive to the exposed roof surface, spreading it evenly to ensure full coverage.
Apply adhesive to the underside of the folded-back membrane as well. Carefully lay the membrane back onto the adhesive-coated roof surface, smoothing out air bubbles with a broom or roller to ensure proper adhesion and a smooth finish.
Step 4: Secure the Seams
Securing the seams is essential for preventing leaks and ensuring the longevity of the EPDM roof. Start by cleaning the areas where the seams will join using a primer and a scrub pad. This step ensures that the seam tape adheres properly.
Next, place the seam tape along the edge of the bottom membrane layer, pressing it down firmly to create a strong bond. Peel off the backing from the seam tape while pressing the top membrane layer onto it. Use a seam roller to press down on the seams, ensuring a watertight seal that will withstand the elements.
Step 5: Install Flashing and Edging
Proper installation of flashing and edging is crucial to prevent water infiltration at the edges and around roof penetrations. Begin by applying primer to the areas where the flashing will be installed. This step ensures better adhesion of the flashing tape.
Cut and install flashing tape around roof penetrations such as vents and chimneys, and along the edges of the roof. To finish, use EPDM-compatible caulk to seal the edges of the flashing tape and any other potential leak points. This additional sealing step provides an extra layer of protection against water infiltration.
Step 6: Final Inspection and Finishing Touches
The final step involves a thorough inspection and finishing touches to ensure the EPDM roof is properly installed. Walk around the roof to check for any air bubbles or loose areas. Use a roller to smooth out any issues, ensuring a flat and secure membrane.
Trim any excess membrane around the edges for a neat and clean finish. Finally, inspect all seams and edges to ensure they are properly sealed and adhered. By taking the time to perform these final checks, you can ensure the longevity and durability of the EPDM roof.
