Zambelli Copper 5" Gutter System FAQ

What type of projects is a 5" copper gutter best suited for?

5" copper gutters are ideal for standard residential homes, garages, and light commercial buildings. They offer more capacity than 4" systems, making them a solid choice for medium-sized roof areas without going as large as a 6" gutter.

Which downspout sizes work with 5" copper gutters?

We recommend using 3" round downspouts as the standard for 5" gutter systems. If you’re dealing with larger roof sections or want extra flow capacity, 4" round downspouts are also compatible.

What copper thickness should I choose: 16 oz, 18 oz, or 20 oz?

  • 16 oz is standard for most residential installs
  • 18 oz offers extra durability without added weight
  • 20 oz is best for areas with heavy snow loads or commercial use

Your choice depends on project scale, location, and budget.

Yes—but it depends on the total roof area. If the roof is both steep and large, you may want to step up to a 6" system for better water flow. Otherwise, 5" is often sufficient for moderate to steep residential roofs.

Will 5" gutters work on steep-pitched roofs?
