Thanks for the reply, that makes sense. Just to clarify, does the ridge board need to be independently supported if it’s separated from the chimney, or is it normally only located by the rafters? Also, when you say the gap needs to be identified and closed off with flashing or similar, are...

Hi all, hoping for some advice on an ongoing chimney leak that’s proving hard to pin down. Background A couple of years ago I noticed water ingress around the face of our chimney stack. A roofer found the chimney pot and flaunching were cracked and replaced them. When that didn’t resolve the...
