Finishing off...
I'd prepared the lead before I started anything and now on this nice cloudy day I made a huge mess cutting grooves with a grinder
Cleaned up with henry. isn't it normal to vacuum a roof? Then fitted the lead which went well. Don't know how you are supposed to do it as I've never done any lead work before but I just retained it with hardwood wedges. Not much groove left once the lead is in so I'm wondering if i need to try filling it or not?
Having persuaded sheet steel and aluminium into all sorts of shapes during my working life the lead seemed quite friendly. You hit it and it stays hit.
Just for completeness here is the wooden trim that is screwed around all the edges. made from some old window sill board that was untouched after being left in the garden for a few years.
So I now declare the roof finished. let it rain..
