Can we talk about how I stopped brushing off clay tile roofs after a job in Danville
I used to think clay tile was mostly a visual check, since the tiles themselves hold up fine and the real work is in the flue and the firebox. Last Tuesday an older sweep from Danville let me tag along on a 1920s place, and he spent 40 minutes walking the courses with a mirror on a pole, checking the underlayment at the valleys and the pan flashing around the stack. He pulled two cracked tiles I would have walked right past, and underneath one of them the felt was soft enough that my thumb went through it. Now I carry a small mirror and a spare tile hook on every tile roof call, and I actually get up on the courses instead of just eyeballing from the ridge. How are you all handling tile roofs when the homeowner says no one has been up there in 10 years?
Read a post from a sweep in the UK who said the same thing, that clay tile is where you find the hidden rot because everyone skips the underlayment check. Ten years of no one up there means you should plan on pulling tiles at the valleys, not just looking at them.
