I have a bit of an issue which I'm unsure on the best way to solve. I know we have a few roofers on here I'd be grateful for any thoughts, or if nothing else they can have a laugh at my predicament.
There are two buildings, one with an existing slate roof the second with a new corrugated sheet roof which joins the wall of the first building just below the eaves forming an unfortunate gully.
The question is how best to deal with this?
My current thoughts are either to build a GRP gully or form one from EPDM which extends up under the sheeting with an upstand under the eaves, although I have concerns that falling slates or branches might damage EPDM.
The fall on the gully is almost negligible, so it needs to be pretty waterproof.
To further complicate things, building 2 extends past the front of building 1 by a couple of meters which is going to make an interesting corner to deal with. The fall of the gully is towards the rear of the buildings.
Sheeting has not yet been laid so it can be cut short to allow a wide gully to be formed.
