A storm counts when the library lists El Paso County among the areas it hit. Each hail size is the storm's largest report, which may have fallen in a neighboring county, and insured losses cover every area the storm hit.

K-style gutters are the standard choice for Colorado Springs homes because the profile carries more water than a half-round gutter of the same width and its flat back mounts tight to the fascia. The main decision is size. A 5-inch K-style gutter suits most single-story roofs and typical slopes. A 6-inch gutter makes sense for large roof areas, steep slopes, long runs and valleys that dump water into one spot. Integrity Roofing and Painting sizes the gutter and downspouts to your roof during a free assessment.

How to choose 5-inch or 6-inch

Gutter sizing depends on how much roof drains into each run and how hard it rains. Ask these questions about your house:

  1. How big is each roof plane? A large single slope sends all its water to one gutter.
  2. How steep is the roof? Steeper roofs shed water faster, and it can shoot past a small gutter.
  3. Is there a valley? Two slopes meeting in a valley pour concentrated water into a short stretch of gutter.
  4. Where do the downspouts go? Long runs with one outlet overflow first.
  5. Do you get overflow now? Overflow in a downpour is the clearest sign the current gutter or downspouts are too small.

A short, heavy thunderstorm tests a gutter harder than a long, steady rain, which is why we size for the worst corner of the roof, not the average one.

Strengths and limits of K-style

  • Capacity. The flat bottom and deep profile hold more water than a half-round gutter of the same width.
  • Mounting. The flat back fastens straight to the fascia with hidden hangers, without exposed brackets.
  • Looks. The front profile reads like trim, so it suits most ranch, two-story and newer homes.
  • Roof edge. The gutter hangs under the drip edge, which the Pikes Peak Regional Building Department requires on shingle roofs in El Paso County, so roof water lands in the gutter instead of behind it.
  • Limits. The inside angles catch debris, and a dent from hail shows on the face. If you want a traditional look on an older home, half-round gutters may suit it better.

K-style and seamless go together

Most K-style gutters we install are formed as seamless gutters on site, so each run is one piece. Add a gutter guard if pine needles fill your gutters every fall. If hail dented your current K-style gutters, have the roof checked too; our hail damage page explains why.

Frequently Asked Questions

Why are they called K-style gutters?

Viewed from the end, the front of the gutter has a decorative profile that loosely resembles the letter K, similar to crown molding. The back is flat, which lets it sit tight against the fascia board.

Are K-style gutters harder to clean?

A little. The inside corners of the profile can hold debris that a smooth half-round gutter would flush out. A guard or a cleaning once or twice a year, especially after the trees drop needles and leaves, keeps them flowing.

Do bigger downspouts help as much as a bigger gutter?

Often more. A gutter can only drain as fast as its outlets let water out. Upsizing the downspouts or adding one at the middle of a long run is sometimes enough to stop overflow without changing the gutter size.
