Hi Guys

I'm looking for some advice on how best to add guttering to my bay window. I've put up with it just dripping on to my window sills and then onto the concrete below for years, but a combination of heavy rain, me working under it and a concern of wet walls, has made me rethink. I was thinking of getting mini-flo or similar, as it's only a small roof. But my problem is the angles.

The front two are 145 degrees, but the two outer ones are 165ish.

The window faces north and either side are walls, which means its rarely completely drying out. Is it possible to bend guttering slightly?

You can get an adjustable angle piece for Galeco's 135mm galvanised gutter that go to 165. There does seem to be a discrepancy whether it's 100-165 degrees or 100-135 degrees - I think it's 165. The gutter section might be a bit big for your bay though - I used this galvanised 135mm on a fairly large garage recently and it looks good, but does look a little larger than we normally see in plastic. AFAIK adjustable plastic corners only seem to go to 156 degrees.

You’ll get away with using 2x 135 and 2 x150’s you can taper the cut of your gutter to help. Miniflow is shyte, it will block up after a week, just stick some normal domestic on there. You get more leverage with round gutter.

A full guttering run round a bay window is always going to look fairly horrid (less so if its a full height 1st floor thing). Is there any scope for redoing the bay roof so it has an upstand & a drainhole at the lowest point?
