Hello there, I'm a specialist in roofing solutions with years of experience in various types of roofing repairs, including rubber roofs. Rubber roofing, also known as EPDM (Ethylene Propylene Diene Monomer), is a popular choice for many due to its durability, flexibility, and resistance to weather conditions. Let's delve into the steps to repair a rubber roof.

Step 1: Inspection and Preparation
Before starting any repair, it's crucial to thoroughly inspect the roof to identify the exact location and extent of the damage. This will help in determining the size and type of patch required. Once you've identified the area, clean it by removing any dirt, debris, or loose rubber. This can be done using a broom or a soft brush. Ensure the area is dry before proceeding.

Step 2: Surface Preparation
The surface needs to be properly prepared to ensure the patch adheres well. If there's any roughness or unevenness, it should be smoothed out using a sanding block or an orbital sander. This step is critical as it helps in creating a clean, even surface for the adhesive to bond with.

Step 3: Cutting the Patch
Based on the size of the damaged area, cut a patch from a new piece of EPDM rubber that is slightly larger than the damaged spot. This ensures that the patch will cover the entire damaged area and provide a bit of overlap for a secure seal.

Step 4: Applying Contact Cement
Now, we come to the step you mentioned. Use a 3-inch paint roller to apply rubber-to-rubber contact cement to one half of the outlined repair area on the roof and to one half of the underside of the rubber patch. This adhesive is specifically designed for bonding rubber materials together. It's important to apply it evenly and avoid any pooling or excess that could prevent proper adhesion.

Step 5: Drying the Cement
After applying the contact cement, allow it to dry for about 10 minutes. This drying time is essential as it ensures the adhesive reaches the right tackiness for bonding.

Step 6: Positioning the Patch
With the cement dried, it's time to set the rubber patch into place. Carefully align it with the outline marked earlier onto the roof. Press the patch firmly into place, starting from the center and working your way outwards to remove any air bubbles and ensure full contact with the roof surface.

Step 7: Securing the Edges
Once the patch is in position, use a roller to press down on the edges of the patch to secure them. This helps in creating a watertight seal and prevents any lifting due to wind or other elements.

Step 8: Sealing the Seams
To further reinforce the repair, apply a seam sealer along the edges of the patch where it meets the existing roof. This sealer will provide an additional layer of protection against water infiltration.

Step 9: Final Inspection
After the patch is secured and the seams are sealed, conduct a final inspection. Look for any areas where the patch might not be fully adhered or where there could be potential leaks. Address any issues as needed.

Step 10: Regular Maintenance
Finally, remember that regular maintenance is key to the longevity of your rubber roof. Regular inspections and prompt repairs can prevent small issues from becoming larger, more costly problems.

By following these steps, you can effectively repair a rubber roof and ensure it remains watertight and durable for years to come. Remember, safety is paramount when working at heights, so always use appropriate safety gear and consider hiring professionals if you're unsure about any part of the process.
