Gutters

K-style gutters have flat bottoms and backs, and the front side of the gutter usually has a decorative shape, such as a curve or ogee, that mimics crown molding. Comes in 5 inch and 6 inch Many styles are available.

Seamless Aluminum

Seamless (or continuous) gutters are made at the job site. A truck with a spool of flat aluminum pulls up to your home, and the fabricator uses a gutter-forming machine to custom make whatever gutter length is required. There’s no hauling of long gutters. About 70% of all gutter installations are the seamless type.

Installing seamless gutters:

• Eliminates many seams and reduces chances of leaks
• Costs slightly more than regular aluminum gutters

Downspouts can come as either round or square, in widths from 3 to 6 inches. The most common sizes are rectangular:

• 2 inches by 3 inches
• 3 inches by 4 inches 

The size and number of downspouts you’ll need depends on the capacity of your system.

Rule of thumb: You need one downspout for about every 20 to 30 linear feet of gutter. To increase the capacity of your gutter system, add more downspouts.
