The Cross House
What is so weird is that it is obvious that the very shingles I removed had been removed not that long ago, and that the inside corner was filled with putty and stuff. And somebody must have removed the original crumbling, rotted 2x6s…but they did not replace them, and then nailed back on all the old shingles (with flat-head exposed nails).
All this damage was caused by a long-term leaking gutter (which I had repaired in 2015). I will now replace the missing 2x6s with pressure-treated lumber, and replace a lot of the diagonal sheathing. I had hoped to save about 50% of the shingles but it now seems that none will be replaced. Sigh. They are just too far gone. Why do all these work just to squeeze another, say, ten years out of the shingles?
