The original roof slope was comprised of a 7' and 4' section, transitioning into a lower 2/12 pitch slope. Most of the leaks were in the transition. After removing the metal panels, we installed "ice and water shield" along the 30' horizontal transition. Instead of replacing the metal panels the same way, we decided to use a 12' panel, folded at the transition, extending 12" into the lower panel, providing seamless, water-tight protection for the client.
Here is a photo of the completed project.
