Flat rubber roofs, known for their durability and efficiency, occasionally encounter issues that require immediate attention to prevent extensive damage. One common issue is water penetration around skylight curbs, a problem that can lead to significant interior damage if not addressed promptly. In this article, we detail a straightforward method to repair a skylight curb leak on a flat rubber (EPDM) roof, ensuring your roofing system remains intact and functional.
The first step in any repair process is accurately identifying the source of the leak. In the case of skylight curb leaks, water penetration often occurs due to a breach in the roofing material surrounding the curb. Thoroughly inspect the area for any signs of damage, such as holes or tears in the EPDM membrane, which might be allowing water to seep through.
Before commencing the repair, gather the following tools and materials:
These tools are essential for ensuring a thorough and lasting repair.
Start by cleaning the area around the skylight curb with the EPDM membrane cleaner and a clean rag. It’s crucial to remove all dirt, debris, and residue to ensure the new materials adhere properly. The cleaner should evaporate quickly, leaving a clean, dry surface ready for the next step.
Apply a thin coat of roofing primer to the cleaned area using a scrubbing pad. This primer acts as an adhesive for the uncured flashing tape, so it’s important not to apply it too thickly. Allow the primer to dry until it’s tacky but not wet to the touch.
Measure and cut a piece of uncured flashing tape to cover the area around the curb, ensuring it extends beyond the damaged section. When applying the tape, start at the top of the curb and smooth it down the sides and onto the roof deck. It’s important to press firmly to eliminate any air bubbles or wrinkles.
Uncured flashing tape is preferred for this type of repair due to its flexibility and ability to conform to the shape of the curb and roof. Cured tape, which is not stretchy, is not suitable for areas requiring a transition up a wall or around a corner.
Once the tape is in place, use a seal roller to firmly bond it to the roof surface. Pay special attention to corners and edges, as these are potential weak points where water could penetrate in the future.
After the repair is complete, inspect the area to ensure the flashing tape is securely attached and there are no gaps or loose ends. Regular maintenance and inspections, especially after severe weather events, can help prevent future leaks and extend the life of your roof.
