Hi @scottishjohn Thank you for your input. I see what you are saying based on how they look, but actually that's mainly down to moss and lichen, looking especially dry and crispy with this current weather. I cleaned the other side of the roof last year but have not got round to doing the side with the flue. Attached is a photo showing how that looked after a clean...

Thank you all for responding and for your help

Hello everyone First post - Thanks for having me on the forum I've had a wood stove installed and wondered if anyone can let me know if it has been done right where the flue comes out of the roof? Looking at other photos on the net at slate roofs they look different. I've taken some photos. The lead is on top of the slates and sealed with mastic, except at the top where it is under the slates and sealed with mastic. Cheers for the help
