Here's a video of a church roof before we got to work on it
This big job involved removing and replacing three layers of felt on the entire roof and finishing with ryno GRP termination bar flashing, poxysilicone, and screws. Once done, a new glass lantern was fitted.
Details of 3 felt layers:
>1st layer - Chesterfelt plus perforated sanded that acts as a vapour barrier protecting the roof underneath
>2nd layer - Axter force line 3w
>3rd layer - Axter force line 4.5ml charcoal torchon
End result below!
