The roof man came to fix my chimney on Saturday. He looked at the leaks inside and diagnosed some of them as caused by water coming through the chimney. So he fixed that first. Then he did a little stabilization (especially the roof square at the lower left of this pic that was formerly a chimney for the kitchen). Just enough to get me through the winter, until I can save enough money to get a new roof.
He says this metal roof is the second roof on this 200-year old house. Underneath the metal is cedar shake. A new metal roof would easily last the rest of my life, and the next owners' too.
It's really nice to be able to trust someone with the roof problem.
