Pitch for gutters?
I live in climate zone 4A in Virginia. Plenty of rain, but not usually much snow. Ranch house with roof of 5/12 pitch, 48 feet long, with a small gable extending out over a porch at one end.
I’m reading a lot of different recommendations for the pitch (slope) of gutters on fascia – anywhere from 1/8″ per foot, to 1/4″ per 10 feet, or to completely level.
I rarely see gutters with any noticeable slope towards the downspouts. But an extremely common problem that I see in my area is gutters sagging along the fascia, with standing pools of water for long periods of time. When you see flocks of starlings collecting in a gutter to drink and take baths several days after a rain, then you know you’re also breeding mosquitoes!
So when we have seamless aluminum gutters installed, how much slope (pitch) would you recommend?
