A short section of barge board is rotting at one end, I suspect because the end section of guttering beyond the downpipe is leaking. Instead of replacing the whole 4m length is it acceptable to scarf a new section in place well beyond the rot? If so what ratio would people recommend for the join? Also I assume I need planed treated wood for the replacement, is this correct?
I am currently weighing up the options of hiring vs buying a ladder enabling me to get up there (5m). Any thoughts on this one appreciated too.
Cutting the joint holds no fears for me, my woodworking skills are well up to it, I've just never had to deal with barge and soffits beyond painting them before.
