5-Inch vs. 6-Inch Gutters: Which Does Your Home Need?
How to decide between 5-inch and 6-inch seamless gutters, explained in plain English by a Roanoke Valley gutter company.
The difference
The number refers to the width across the top of a K-style gutter. A 6-inch gutter holds and carries noticeably more water than a 5-inch one, and it’s usually paired with larger downspouts.
When 5-inch is enough
Most single-family homes with average roof size and pitch do well with 5-inch gutters, as long as downspouts are placed properly.
When 6-inch makes sense
Steep roofs, large roof areas draining into one gutter, long runs, valleys that dump water into one corner, or a history of overflow during heavy storms are all reasons to consider 6-inch.
Don’t forget the downspouts
Sometimes overflow isn’t a gutter-size problem at all — it’s too few downspouts or downspouts that are clogged. A good estimate looks at the whole system.
Quick answer
Are 6-inch gutters better?
Not always — they’re better for roofs that send a lot of water into one gutter. For many homes, 5-inch works fine.
