this went more smoothly than we thought. Â we used clamps and 2x4s to bend the flashing into shape. Â i had been warned several times to work in 8′ lengths and this was good advice. we bent the edge exposed to the plastic back on itself to help prevent tears. Â we found using another piece of wood to run along the bend helped get sharp and consistent edges. Â the clamps in the picture are where we pegged the pieces together with “eternebond” Â on the advice of our solar installers who deal with all kinds of roof sealing situations. Â we ended up cutting a new piece of vinyl siding and hooking the bottom and nailing the into holes we drilled.
