Flashing around furnace chimney from peak to eave?
I'm shingling a roof and the homeowner wants metal flashing from his peak to the eavestroph centered aroung his chimney. He says it is to prevent fires. I have never done this and I was wondering if anyone has some ideas on how it should be done.
I was going to just shingle the roof as usual and then place the tin (32" wide) around the cimney from the ridge cap to the eave.
