I found a leak on my roof where the awning strip attaches. I removed 6 screws at the end where the leak was, filled the holes with wood and glue, and rescrewed using larger diameter screws, and covered with lap sealant. The screws appear to just screw into the thin wood sheathing, no joists. These all seem to hold well, except for the end screw, where the leak was the worst. I think the wood is too damaged to hold the screw. At this point on the roof, the roof is buckled, about 4" by 6". My guess is the roofing, which I assume is plywood, or presswood, is buckled due to water damage. My plan was to apply etenabond the entire length of the awning strip. My question is, do I need to address this buckled spot, or since the leak will be repaired, no further damage is expected. I appreciate any suggestions. Thanks.
