The inside corner of this roof developed a leak. The flashing was too narrow and poorly installed. The plywood decking and fly rafter were both rotted through. I sistered up the fly rafter on the back side and tied it all together with glue and screws. It's stronger then before for sure. I didn't show it on the video, but I added flashing tape to the roof edge and inside corner and added some other hidden flashing under the shingles.
