Beat the dark and reroofed the allotment shed the wind had seen off the old felt it had gone brittle and was flapping a bit
had the old boy who over looks us telling me I was doing it wrong obviously being helpful no malice or anything ..
(flat roof style shed so no hip/ ridge )
. "you've put the top on first so your overlap will be wrong way... "
think I blew his mind when he saw how I did it
It's about 2500mm deep is the roof the felt is 1000mm wide
So there's a 500mm to loose / lap
Measure twice cut once and all that jazz
Tacked the top piece in place along the top and half way down each side
Fully fixed the bottom along the gutter line evenly then slid the middle piece into place tucked it under the upper sheet over the bottom then fixed into place no trimming required bar cutting to width like the other pieces .
Then clout nailed and fixed laths and barge boards to fully secure the felt
Work smart not harder :lol
He did give me the nod of respect when I shouted for him to watch this bit as I put the last piece on the roof as i climbed up
