I've hired a builder to renovate my cottage at a fixed contracted price and he has sub-contracted the roofing work. I agreed with the builder that the best slates from the front half should be replaced (on new battens) and the shortfall of reusable slates should be dealt with by taking decent ones from the back. Today after the roofers had left I went up on the scaffolding and this is what I found. Surely some of these slates going back on are beyond salvage? And what horrors lie beneath the area already covered? I anticipate a bit of an argument with the builder tomorrow and it would be great for my confidence if some of you found this as bad as I do. But I can take it if you think I'm making a fuss about nothing!
