Our house was built in the 1920's and has had several additions since. As a result, there is a weird roofline arrangement at the back of the house.
There is quite a bit of roof area that drains to a pretty small, awkward section of gutters. Because of the volume/speed of the water coming down the valleys, the gutters get overshot or overloaded (not entirely sure which). These are 5" gutters currently. I'm considering trying out 6" gutters and adding downspouts to the long section in the middle. Thoughts? Preferably ones that avoid re framing the roof?
