Seamless Commercial gutters are used for larger roof areas. The 6" mouth opening allows the gutter to handle more water shed in heavy down pours. The Commercial gutter is also deeper also allowing a larger volume of water to flow in it. Many residential houses that have 12/12 pitched roofs also install wider gutter to keep water from over shooting the gutter. Commercial buildings where using 10 or 20ft sectioned box style gutters and have started switching to 6" seamless gutters. Rainline can make these gutter systems out of aluminum or copper. We don't recommend it to be made from painted steel because they will rust and not last as long as other materials offered by Rainline.

"So if you have a metal,tile or slate roof or a steep roof you will need 6"seamless commercial gutters."
