The "K" style gutter is the standard for most homes. It comes in 5" AND 6" sizes and IS INSTALLED seamlessly AND IS Available in copper and aluminum.

 

5" gutters are mainly used for smaller homes
whose roof does not have a lot of pitch and valleys.

 

6" gutters are mainly used for larger homes with a higher concentration of water flow because of larger roofs
that have steeper pitch with varying angles and valleys.
