Everything You Need to Know About Gutter

What is Gutter?

A gutter is a channel installed along the edges of a roof designed to collect and divert rainwater away from a building. Gutters are crucial for preventing water damage to the building’s foundation, walls, and landscaping.

Types of Gutters

Various materials and designs offer different benefits. Let’s explore some of the most common types of gutters.

Cast Iron Gutters

Cast iron gutters are known for their durability and traditional appearance. Often found on older or period-style buildings, they can last for many decades if properly maintained. However, they are heavier than other materials and require regular painting to prevent rust.

UPVC Gutters

UPVC gutters are a popular choice due to their affordability and low maintenance. They are lightweight, easy to install, and available in various colors. UPVC is resistant to corrosion and does not require painting, making it a practical choice for many homeowners.

Stainless Steel Gutters

Stainless steel gutters are extremely durable and resistant to rust and corrosion. They maintain their shine for years, adding a modern touch to the building’s exterior. While more expensive than other types, their longevity and low maintenance make them a worthwhile investment.

Seamless Gutters

Seamless gutters are custom-fitted to your home and lack seams along the gutter length, reducing the chances of leaks. They are typically made from aluminum, but can also be found in copper and steel. Seamless gutters offer a neat, clean appearance and require less maintenance.

Zinc Gutters

Zinc gutters are known for their longevity, often lasting upwards of 50 years. They develop a protective patina over time, which shields against corrosion. Zinc gutters are eco-friendly and recyclable, making them a popular choice for environmentally conscious homeowners.

Aluminum Gutters

Aluminum gutters are lightweight, rust-resistant, and easy to work with, which makes them a favorite among DIY enthusiasts. They can be painted to match your home’s exterior and are affordable, making them a common choice for residential properties.

Finlock Gutters

Finlock gutters, also known as concrete gutters, were popular in the mid-20th century in the UK. Made from concrete blocks, they are robust but can be prone to issues like leakage and thermal movement. Repairing or replacing these gutters can be more complex than other types.

Vernacular Gutters

Vernacular gutters are designed to blend with the local architectural style and are often made from materials typical to the area. This type of guttering is more about aesthetic harmony with the building’s design and local tradition than about functionality.

Shapes of Gutters

K-Style Gutters

K-Style gutters are named for their profile’s resemblance to the letter ‘K’ when viewed from the side. They are the most common gutter type in many countries, particularly in modern residential properties.


  • Appearance: These gutters have a flat bottom and back, with the front side usually featuring a decorative shape, like a curve or ogee, which mimics crown molding. This design adds a stylish touch to the home’s exterior.
  • Capacity: K-Style gutters are known for their high capacity. They can handle more water compared to round or square types, making them ideal for regions with heavy rainfall.
  • Installation and Cost: They are relatively easy to install and are available in various materials, including aluminum, vinyl, and copper. Their widespread popularity often makes them a cost-effective option.

Round Gutters

Round gutters, also known as half-round gutters, have a simple, semicircular design. They are especially popular in older or historic homes but are also used in modern constructions for their sleek look.


  • Efficiency: Their smooth shape allows for efficient water flow and reduces the chances of clogging by leaves and debris.
  • Aesthetics: Round gutters offer a classic, elegant appearance. They are often made from copper or galvanized steel, adding a distinctive charm to the building’s exterior.
  • Maintenance: They are generally easier to clean due to their simple shape but might need more frequent maintenance in areas with heavy leaf fall.

Square Gutters

Square gutters, as the name suggests, have a square or rectangular profile. They are less common than K-Style or round gutters but offer specific advantages in certain architectural contexts.


  • Design Flexibility: Square gutters can complement both traditional and contemporary home designs. Their sharp lines and angles can enhance the architectural features of a building.
  • Capacity: These gutters can hold a significant amount of water, making them suitable for areas with heavy rainfall. However, their capacity is generally slightly less than that of K-Style gutters.
  • Material and Durability: Square gutters are available in a variety of materials, including aluminum, vinyl, and steel. Their design can make them more prone to blockages, so regular maintenance is essential.

What is Seamless Gutter?

Seamless gutters are made from a single piece of material, typically aluminum, and are custom-fit to a building’s measurements. The lack of seams minimizes leaks and requires less maintenance, making them a popular choice for modern gutter systems.

What is Gutter Apron?

A gutter apron is a type of flashing used to direct water into the gutter. It’s a long, L-shaped piece of metal installed over the roof edge and beneath the shingles, ensuring that water flows into the gutter, not behind it.

How Much Does Gutter Cost?

The cost of gutters varies depending on the material, size, and type. On average, homeowners can expect to pay between $3 to $30 per linear foot. Factors like the complexity of installation and regional labor rates also influence the final cost.

How to Measure Gutter Size

To measure gutter size, measure the length of the roof edges where you plan to install gutters. Also, consider the roof’s pitch and the average rainfall in your area, as these factors determine the gutter’s size and capacity needed.

How to Install a Gutter?

Installing a gutter involves several steps:

  1. Measure and prepare the gutter sections.
  2. Set up the hangers that will support the gutters.
  3. Cut the gutters to size and attach end caps.
  4. Secure the gutters to the hangers and ensure proper slope for water flow.
  5. Install downspouts to direct water away from the foundation.

How to Clean Gutter

To clean gutters, you’ll need a ladder, gloves, and a garden hose:

  1. Remove debris (leaves, twigs) by hand or with a gutter scoop.
  2. Flush the gutters with a hose to clear out remaining dirt.
  3. Check for and clear any blockages in the downspouts.

How to Fix a Leaky Gutter?

To fix a leaky gutter:

  1. Identify the source of the leak.
  2. Clean the area around the leak.
  3. Apply gutter sealant to small holes or cracks.
  4. For larger damage, patch the area with a piece of the same gutter material.

How to Cut a Gutter?

Cutting a gutter requires the right tools like tin snips or a hacksaw:

  1. Measure and mark the cutting line on the gutter.
  2. Secure the gutter to prevent movement.
  3. Cut carefully along the line.
  4. Smooth out any sharp edges with a file.

Remember, while DIY gutter installation and maintenance are possible, hiring a professional can ensure safety and quality, especially for complex projects.
