Understanding Low Slope Roof & Flashing Failures

Erik Mattsson, owner of Mattsson Roofing in Glen Rock, NJ provides insights into why roll roofing systems and their flashing components might start to fail.



Identifying the Problem:

Erik points out this roof had approximately five leaks. He emphasized that understanding the root causes of these leaks is essential for effective solutions. A key aspect of the roof in question was its structure. Erik described it as a low slope wall roofing system abutting an eve or facial wall. This particular setup can present unique challenges in waterproofing and weather resistance.

One of the primary issues Erik identified was with the vertical flashing. Over time, this component had become undone. In situations involving wind-driven rain, this defect can allow water to accumulate and seep underneath the flashing, leading to leaks beneath the roll roofing.

Another significant point Erik raised was the condition of the tar at the seams of the roll roofing. He noted visible cracking, which is a telltale sign of material degradation. This cracking can compromise the roof's integrity and lead to further water intrusion.

Underlying Roofing Conditions:

A crucial aspect of Erik's assessment was the condition of the roll roofing underneath. He suggested that if the base layer is compromised, it exacerbates the overall problem, making superficial repairs less effective.

Erik's insights emphasize the importance of proper installation, regular maintenance, and considering long-lasting repair solutions. As homeowners or property managers, it's crucial to understand these aspects to ensure the longevity and effectiveness of your roofing systems.
