Hello,
I’ve recently bought some trapezoid-profile insulated steel roof panels for my garden room, but am having difficulty understanding how to achieve a fall with the supplied folded-sheet box guttering.
It has support straps that fasten from the crown of the trapezoid box to a lip on the far side of the gutter, and then additional fasteners on the valley of the box to the near side.
My question is how to achieve a fall with this system, as the straps are rigid and there’s no way of easily changing the height of any fixings.
I can only think of 2 solutions:
1. Reposition the outlet side of the gutter to be further from the building, which would create a fall line but destabilise the gutter and make it prone to wind catching, as well as being aesthetically displeasing.
2. Use plastic shims to pack the fastenings and adjust the height that way
Has anyone any ideas about this? I think this system is used in commercial guttering (warehouses, supermarkets etc) so would be interested to know how it’s resolved in those settings.
