This post is all about the various types of gutter styles and what to choose for your new gutter system.
Let’s start with shapes. There are two basic types, and they’re referred to by the shape of their cross section. Both types come in 5- and 6-inch widths.
#1 K Style Gutter System
The K Style are probably the most popular gutters in the market today. In General K-style gutters have twice the capacity of their half-round cousins of the same width.
# 2 Half Round Gutters
Half-round gutters are exactly what the name suggests: half-round tubes. Half-round gutters often are found on older, historic homes.
Gutter MaterialsResidential gutters are made from various metals, including:
Cost of pro install (materials and labor): $4 to $9 per linear foot
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:
Cost of pro install (materials and labor): $8 to $10 per linear foot
Cost of pro install (materials and labor): $3 to $5 per linear foot
Downspouts come as either round or square, in widths from 3 to 6 inches. The most common sizes are rectangular:
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 30 to 40 linear feet of gutter. To increase the capacity of your gutter system, add more downspouts.
