Working From a Standing-Seam Roof
Attach walking planks without putting holes in the roof
I was recently siding a second-story wall while working off a standing-seam roof, and I thought I would share how we staged it. After determining the roof’s pitch (3-in-12), we cut 2×12 blocks to the complimentary angle of the pitch (76°) and applied flashing tape to their longest sides to protect the roof. Then we clamped the blocks to the standing-seam joint, as shown in the drawing. With the blocks in place, we fastened 2×12 walking planks to the blocks, being careful not to screw into the roofing.
