K-Style Gutters for Your Home

During the gutter-buying process, there are several factors a homeowner must consider in order to get the right gutter system for their home. The shape of the gutters or the gutter profile is one of those major decisions. For residential applications, K-style gutters are the most popular for several practical reasons.

Standardized Profiles

There is a differing opinion on why they are called K-style. Majority rule claims it’s because the shape loosely mimics the letter K; others in the industry state it reflects back to when gutter profiles slowly became standardized in the 1970s. A range of channeled gutters that could be formed on factory or portable (on site) gutter machines were designated with letters of the alphabet: “K” became the most popular. Who knows? Both could be true.


When viewing the gutter from the side, starting from the bottom, the outer edge consists of a short, straight line, followed by two curves (opposing), then followed by another short straight line to form the top or lip of the gutter.

A K-style gutter system typically channels more water than some other gutter profile systems, including half-round.

Because the shape is comprised of multiple bends, it makes the metal stronger and more resistant to damage by impact.


K-style gutters, also known as OG (for Old Gothic) or ogee (meaning double curve), resemble the crown molding found on interior walls adjacent to the ceiling. While it might seem that a K-style gutter system would be better suited to traditional and heritage architectural style homes, just the opposite is true. In today’s market, where there are more material and colour choices, K-style gutters are able to complement a wide range of residential styles from Revival to Craftsman to Modern.

Choice of Materials

K-style gutters are available in a number of material choices, including aluminum, galvanized steel, and copper. K-style aluminum gutters are low maintenance, lightweight, and economical. A galvanized steel k-style gutters system is durable, strong and corrosion-resistant. Copper k-style gutters are long-lasting, beautiful to look at, and strong.


Regardless of what type of metal is chosen for the gutter system, there are definite advantages to K-style gutters. These include:

  • channels more water per linear foot than other types of gutter profiles
  • since it’s the most popular gutter profile, the seamless option is readily available
  • versatile, classic shape that resembles crown moulding
  • possesses a flat back, which makes it easier to attach directly to fascia

When Buying Gutters Decision No. 3 – Size

The third decision a person buying a gutter system makes is the size of gutter. Gutter size is the measurement from the back to the front of the opening to the gutter channel. The larger the gutter, the more expensive the gutter system will cost. But it’s important to get the gutter size right – too small, the gutters won’t be able to handle the amount of rainwater flowing through the system; too large, they can become expensive overkill.

Determining the Required Gutter Size

While the total square footage of the roof is the main determining factor, there are other things to consider when selecting the correct gutter size that will protect your home. These other factors include:

  • calculating the square footage of the drainage area
  • establishing the annual rainfall for the past seven to 10 years
  • determining the number of inches falling per hour in extreme rainfall conditions
  • establishing the gutter system’s handling capacity based on profile (shape), including the number of downspouts

If you plan to install the gutters yourself, there are a number of gutter size calculating tools available on the internet.

Gutter Sizes

The most common residential gutter sizes capable of handling the typical amount of rain that falls in the Vancouver area are 5-inch K-style and 5-inch half-round gutters.

For larger homes or homes with a multi-level roofing system, standard 6-inch K-style or 6-inch half round gutters would be used.

Depending on climatic and microclimate conditions, a six-inch gutter system can channel up to 45% more water than 5-inch gutters.

Downspout Sizes

An integral part of the gutter system is the downspout. A determining factor for how many downpipes your gutter system might need is one downspout for each 30-foot section of gutter.

A rectangular 2 x 3 inches downspout or a round 3-inch downspout is typically paired with 5-inch gutters.

Standard 6-inch gutters are commonly matched with a rectangular 3 x 4 inches downpipe or a round 4-inch downpipe.

When added gutter size, for example, a 7-inch gutter system, would spoil the aesthetics of a home’s exterior, often 5-inch gutters are used with a larger downspout size to help an increased volume of water exit the gutter system.

Choosing the Right Gutters for Your Business

Whether you own a small dress shop, trending restaurant, maintenance and repair garage or large warehouse, you’ll need gutters. Choosing the right gutter system can help build a customer base, maintain a trustworthy reputation, and expand your brand. Gutters that enhance a building’s appearance add value to your commercial property.

The Right Gutters Add Curb Appeal

Gutters aren’t just functional. Curb appeal has a dramatic impact on the overall appearance of your business. Your customer’s first impression is important in establishing an ongoing relationship. A gutter system for commercial and industrial buildings is typically larger in size, and therefore more visible to the eye. So, it is important, aesthetically speaking, you select gutters that look good while saying something about who you are as a corporate entity. Principles for choosing commercial gutters that create universal curb appeal are:

  • gutter material choice – for example, seamless aluminum gutters for an edgy urban look
  • gutter colour – bolder colours make them stand out
  • gutter profile – shape of the gutter gives character or definition to a gutter system

The Right Gutters Protect Your Investment

Like residential gutters, a commercial gutter system is designed to capture rainwater, direct it to the downpipes, and guide runoff safely away from the building. A gutter installation contractor will help you:

  • determine the size of gutter required to handle the volume of water that typically falls in your area in a year
  • decide what type of gutter – box gutters, seamless vs. sectional, half-round copper gutters
  • the right size and number of downspouts
  • applicable bylaws and codes regulating drainage, where runoff is discharged, etc.

When your commercial property or business is fully protected, you’re ensuring that day-to-day operations won’t be interrupted because of water damage, stained exterior walls, pest infestations or health issues.

The Right Gutters and Public Perception

While they might look the same, gutters for commercial buildings are designed specifically for your building’s size, roofing system, and architectural characteristics. When you install commercial gutters, you add a layer of protection to your investment. Whether you are selling products or providing services, a commercial property that looks attractive and cared for gives your customers and clients the impression they have come to the right place. In today’s world of high-tech digital marketing, word-of-mouth remains a highly effective branding technique.

Residential Gutter Sizes

Residential gutters share some common denominators, but no two houses are exactly alike when factoring in architectural features, climate and microclimate. Purchasing a gutter system for your home involves a lot of decisions. One of the most important choices is the size of the gutter and the corresponding width or diameter of the downspout.

Gutter Size Basics

Gutters are designed to properly channel water into the downspouts. The size of the gutter should never be selected for the amount of water it can “hold.”

Gutter size refers to the opening at the top of the gutters and not to the depth of the gutter channel. Most residential gutter systems use 5” gutters or 6” gutters. A larger size gutter system will generally be more expensive.

Regardless of the gutter profile (the shape of the gutter), a gutter is measured from the back to the front, at the widest part.

K-style 5” gutters can easily channel a large volume of water.

While it might not seem like much, one inch more significantly impacts the amount of water a gutter system can handle. Six inch gutters typically channel anywhere from 30% to 45% more water than 5” gutters.

Determining Gutter Size

To determine what size of gutter is best for your home, combine the total square footage of the drainage area, roof pitch, gutter slope and the rainfall intensity (number of inches falling per hour). Other factors such a roof configuration, the gutter profile and microclimate (lots of trees growing near the house).

Gutter and Downspout Combinations

A standard 5 inch gutter system is typically accompanied by a 2 x 3 inch downspout.

K-style 6 inch gutters work well with 3 x 4 inch downpipes.

Depending on the size of the house and the amount of local rainfall, a 5 inch gutter paired with a 3 x 4 downspout might a more practical combination.

Common DIY Gutter Installation Mistakes

Even when you’ve invested in quality materials, are confident about your DIY skills, and created a gutter installation plan complete with one or two layout drawings, a gutter system must be installed correctly to work properly. If installing gutters is the next DIY project on your list, avoid making these common gutter installation mistakes.

Wrong Gutter Material

Some homeowners will be drawn to the gutter material that looks good and is the cheapest. While appearance and cost are two criteria in choosing the material for your gutters, other factors should be considered as well. Choose the gutter material best suited to the climate, the architectural style of your home, and how much time and effort will be required to maintain it.

Wrong Size

Gutters that are too large unnecessarily raise the cost of the installation. Upgrading to a 6” or 7” gutter when you only need standard 5” guttering can also compromise the esthetics of a home. Too small, you run the risk of constantly overflowing gutters. Gutter size should be based on the annual rainfall for your local region.


In the process of installing gutters, several major calculations are required.

  • How much – number of linear feet of guttering
  • How many – number of downpipes and the proper placement
  • How many – number of hangers and their appropriate spacing
  • Pitch or slope – the amount of downward angle needed to direct water toward the downspouts

Any miscalculations can negatively impact the gutter installation, jeopardizing the longevity and functionality of the gutter system.


While the gutters should gently slope downward, the gutter section itself should be level. A common installation mistake is to install the gutter with a slight tilt, either toward the front or back.


Another often-seen installation mistake by contractors is the position of the gutter too close to the roofline. Gutters should hang several inches below the edge of the roof. This allows runoff to enter the gutter system and flow into the channel and toward the downspouts. When the gutters are installed up too high, there is the danger of water being pushed back and then spilling over the sides.

Too Many Seams

While gutter sections that are too long can be difficult for the do-it-yourselfer to handle, the number of seams should be kept to a minimum. Wherever two gutter sections are joined together, there is the potential for leaks. Too many seams weaken the gutter system’s ability to protect your home from water damage.
