I am replacing the metal, square, downpipes on my 30+ YO house as most have rusted out and are leaking into the eve space.
Have one concealed downpipe (comes out the back of the gutter) that is only accessible from the tiles above or through the eves below, due to the add-on of a veranda. My preference is to cut a hole in the bottom of the gutter for the new downpipe and seal up the existing outlet. I have done this to another downpipe successfully at another part of the house where I can get access to the bottom of the gutter from below, but this one is just impossible to get to unless I cut a big hole in the metal veranda itself. I want o get the water away from the gutter a quick as possible and do not want to run an almost flat pipe again in the eve space.
I therefore plan to cut the existing square outlet from the back of the gutter as short as I can from the gutter and attach the new 90mm downpipe to this, via a 45deg bend going down through the eves to the wall, and then down to the existing pipe work.
My question is –“What do I use to cut the fibro sheeting that forms the underside of the eves?”
I guess it as asbestos sheeting given the age of the house, so appropriate precautions will need to be taken.
I have considered the use of an angle grinder with a cut-off disc, to cut a square hole (for a round pipe!) but what sort of disk?
Any suggestions gratefully accepted
