I’ve not fitted it yet, but got a load of Coroline bitumen corrugated sheet ready to re-do our shed roof.
We’ve got no boards down as the current roof is clear polycarb sheets. I think the previous owner used it as potting shed.
This got about 30 holes in it a couple of yrs ago during a particularly heavy hailstorm (which also dented the car!) Which I covered with gorilla tape, but that’s all peeling off.
The extra timber I need to strengthen the roof up, 4 roof panels, 4 ridge pieces and the screw in fixings (from Screwfix) came in at <£200.
