Further in the saga of our cowboy-built extension, any thoughts on whether I can bodge repair this below.
The top is the gutter channel off the flat extension roof that goes into the drain pipe at the bottom of the pic. Under the 'lip' is now rotten hardboard that i need to protect/replace as water is now leaking inside, presumably through that.
I was thinking to bend up the lip bit and scrape out as much rotten as possible, then fill/cover with something waterproof?
Flexacryl and some 'scrim' is good - the scrim provides a scaffold for the Flexacryl to bond to. The thin fleece material that you wrap plants to protect them from frost would work.
