Which size of Gutter do you need?

A properly sized seamless gutter is crucial for effective water management and the protection of your home. If gutters are too small, they may become overwhelmed during heavy rain, leading to overflow, water damage, and erosion around your foundation. Conversely, gutters that are too large can be prone to excessive weight and potential structural issues if not installed correctly. 


Proper sizing ensures that gutters can efficiently channel water away from your roof and foundation, reducing the risk of leaks, mold, and costly repairs. Additionally, well-sized gutters contribute to the longevity of your gutter system and maintain the overall integrity and aesthetic of your home.

Seamless Rain Gutters

5" K Gutter

The 5" K Style seamless gutter is the most common and cost-effective system, making it a popular choice in the Flathead Valley. Given our generally moderate rainfall this system is well-suited for most roofs, provided that the downspouts are appropriately sized and positioned. Its widespread availability and reliable performance make it a practical option for effectively managing rainwater and protecting your home.

6" K Gutter

This system is typically installed on commercial buildings and structures with larger roofs, as it can handle up to twice the water volume of a 5" K gutter. However, a 6" K seamless gutter must support significantly more weight from snow and ice buildup, and is more prone to failure if clogged. Proper installation and regular maintenance are essential to ensure its effectiveness and prevent potential issues.

6" Half-Round Gutter

The 6" Half-Round gutter system is renowned for its aesthetic appeal, enhancing the curb appeal of any home with its elegant, classic design. While it handles the same water capacity as a 5" K-style seamless gutter, it is considerably more expensive due to the increased installation time and higher material costs. Despite the greater investment, the distinctive appearance and refined look of the Half-Round system can add substantial value and visual appeal to your property.

Your Reliable Gutters and Downspout Experts

Choosing the correct downspout size and location is just as essential as the gutter themselves. 


Proper planning for drainage is very important. A gutter system installed without proper drainage planning can lead to dysfunctional gutter systems. This can cause pre-mature system failure and extensive property damage.

2x3" Downspout

For a roof area of approximately 900 square feet, a 5" gutter system is often the most suitable choice. This size is widely used due to its balance of efficiency and ease of installation. The 5" gutter is well-regarded for its ability to manage rainfall effectively, making it a popular option among homeowners. Its popularity is also attributed to the availability of materials and the straightforward installation process, which contribute to its cost-effectiveness. Whether for residential or smaller commercial applications, the 5" gutter system provides reliable performance while maintaining accessibility and affordability, ensuring that it meets the needs of most standard roofing systems.

3x4" Downspout

A 3x4 downspout is typically recommended for a 6" K gutter system and is designed to effectively handle drainage for approximately 1,800 square feet of roof area. This downspout size is particularly useful when a 2x3 downspout is insufficient for managing water flow. Although the 3x4 downspout involves higher labor and material costs compared to the smaller downspout, its benefits outweigh the additional expense. The larger size enhances drainage capacity and reduces the likelihood of clogs, as debris is more likely to be flushed through rather than accumulating and blocking the system. This makes the 3x4 downspout an excellent choice for both 6" K gutters and 5" K gutters, offering an effective alternative to gutter covers while ensuring efficient water management and fewer maintenance issues.

3" Round Downspout

A standard round downspout system effectively handles drainage for approximately 1,000 square feet of roof area, making it a reliable choice for managing water runoff on medium to large roofs. This system not only ensures efficient water flow but also enhances the curb appeal of your home with its classic, aesthetically pleasing design. Additionally, round downspouts can be paired with 5" K-style gutters or box gutters to offer both functional benefits and an upgraded look, providing a stylish alternative while maintaining effective water management. The combination of functionality and visual appeal makes half-round downspouts a versatile option for homeowners seeking to improve both performance and aesthetics.

4" Round Downspout

A 4" round downspout system effectively handles drainage for approximately 2000 square feet of roof area, making it a reliable choice for managing water runoff on large roofs. This system not only ensures efficient water flow but also enhances the curb appeal of your home with its classic, aesthetically pleasing design. Additionally, 4" round downspouts can be paired with 6" K-style gutters or 6" box gutters to offer both functional benefits and an upgraded look, providing a stylish alternative while maintaining effective water management. The combination of functionality and visual appeal makes half-round downspouts a versatile option for homeowners seeking to improve both performance and aesthetics.
