If you have ever wondered why the most common gutter shape in Idaho is called "K-style," the answer traces back to an industry group, not a marketing team.
Where the Name Comes From
The Sheet Metal and Air Conditioning Contractors' National Association, known as SMACNA, is an international trade association that helped set standards across the sheet metal industry, including gutter profiles. When SMACNA catalogued the different gutter shapes available, the eleventh profile on the list was assigned the letter "K," and the name stuck.
Why It Is So Popular
K-style gutters have a finished look, similar to crown molding, that pairs well with almost any home style. Beyond looks, the profile is efficient at catching and moving water toward downspouts, which is the entire point of a gutter system in the first place.
We install K-style gutters in both 5 and 6 inch sizes, in aluminum or steel, and in more than 25 colors. Which size is right for your home depends on roof square footage, pitch, and local rain intensity, which we calculate at your free assessment rather than guess.
K-Style vs Box Gutters
Box gutters are a newer addition to our lineup: a flatter, more modern profile common on commercial buildings and increasingly requested on residential homes. Box gutters often pair with round downspouts instead of the traditional rectangular style. Both profiles are formed on site to your exact roofline, so either way you get a seamless system with no mid-run joints.
