When it comes to home maintenance, your roof gets a lot of attention, but the unsung hero protecting your property is your gutter system. A properly functioning eavestrough channels rainwater away from your foundation, landscaping, and walls. However, when it’s time for a new eavestrough installation, homeowners in Brantford and the surrounding Southern Ontario region often face a critical question: Should you choose 5-inch or 6-inch gutters?
At Cameron Bros Exteriors, we want to help you make an informed decision. Let’s break down the differences in the 5-inch vs 6-inch gutters debate to find the perfect fit for your roofline.
Understanding the Basics: Capacity and Design
Historically, the standard choice for many residential properties has been 5-inch eavestroughs. These are typically crafted as aluminum eavestroughs because the material is durable, lightweight, and rust-resistant. Most residential systems feature the popular K-style design, though some architectural styles utilize half-round options.
While a 1-inch difference might seem negligible, the math tells a different story. A 6-inch K-style eavestrough can hold up to 40% more water volume than a 5-inch system. This massive upgrade in water flow capacity makes 6-inch gutters an increasingly popular choice for modern gutter installation projects.
Factors That Determine Your Ideal Gutter Size
To choose the right gutter size, you need to consider the unique architecture of your home and local weather patterns:
- Roof Size and Roof Area: The larger your roof area, the more water your eavestrough needs to collect. A sprawling roof collects thousands of gallons of water during a storm, requiring a system that won’t overflow.
- The Roof’s Pitch: Steep roofs cause water to rush down at high speeds. Even if your overall roof size isn’t massive, steep roofs accelerate water flow, often causing water to overshoot standard 5-inch eavestroughs.
- Complex Rooflines: Homes with multiple valleys, peaks, and intersecting rooflines funnel large volumes of water into specific, concentrated points.
Why Heavy Rainfall Demands Better Drainage
Southern Ontario weather can be unpredictable. With the increase in sudden, heavy rainfall events, standard systems can easily become overwhelmed. When water overflows, it doesn’t just splash your lawn—it pours directly onto your fascia boards, seeps into the soffit, and pools around your foundation. Over time, this leads to costly water damage, including wood rot, mould, and compromised structural integrity.
Upgrading to 6-inch eavestroughs provides peace of mind that your home can handle torrential downpours without overflowing.
Don’t Forget the Downspouts and Accessories
An eavestrough is only as good as its ability to shed water. If you upgrade to a 6-inch system, proper downspout sizing is mandatory. Pairing larger gutters with larger downspouts ensures that water moves away from your home quickly without backing up.
Additionally, larger gutters are easier to clean and maintain. They can be fitted with heavy-duty hangers spaced closely per linear foot to support the extra weight of the water. To make your system completely worry-free, we highly recommend installing gutter guards. Gutter guards keep leaves and debris out, ensuring uninterrupted water flow and protecting your investment.
The Verdict: Which Should You Choose?
- Choose 5-Inch If: You have a standard, moderately pitched roof, a traditional roofline, and have never experienced overflowing issues during storms.
- Choose 6-Inch If: You have a large or steep roof, complex valleys, or are currently experiencing water spilling over your current gutters. It is also the superior choice for commercial properties.
