Signs of Undersized Gutters (And How to Fix Them For Good)

How Do I Know If I Have Undersized Gutters?

• Overflows: Keep an eye on your gutters during downpours (it’s worth standing in the rain for a bit to double check your gutters are working correctly!). If they’re overflowing, this is a definite sign of undersized gutters – especially if it’s happening at the corners.
• Clogging: This check will require using a ladder, so be extra careful and always ask someone to hold it at the bottom for you. Once you’re safely at the top, have a look for any build-up causing clogs in the gutter (e.g. leaves, twigs, other seasonal debris, etc.). If this is left, it can seriously affect the performance of your gutters.
• Erosion: If your gutters aren’t draining properly, water can pool near the foundations of your property, causing erosion and potentially affecting the structural integrity of the building.

How Do I Choose the Correct Gutter Size?

The correct gutter size is relative to your roof’s pitch, the total surface area, local rainfall levels, and the type of gutters you have. Below is a quick guide to common types of gutters, the optimal sizes for each type, and our Sectional Aluminium Guttering range for more information.

Common Types of Gutters & Gutter Sizes:

• Box Gutters: Popular due to their modern, discreet aesthetic appeal (box gutters are typically concealed between two parallel roof surfaces) and high flow capacity. Due to this capacity, sizes are typically larger – ranging from 100-200mm in length.
• Half Round Gutters: Commonly used to match the look of traditional properties, half round gutters are ideal for refurbishment projects (as they can be fully interchangeable with existing gutters of a similar size) and areas with moderate levels of rainfall (due to their smaller, standard sizes compared to other profiles). Standard sizes usually start from 100mm.
• Ogee Gutters: Perfect for adding an elegant, decorative touch to your property, Ogee gutters come in ornate styles and offer an impressive flow capacity for their size due to their unique shape. Sizes usually vary from 100-200mm.
• Commercial Gutters: Commercial buildings generally have larger roof surface areas and therefore, need larger gutter profiles to handle the extra water flow. Common sizes start from 150mm or more, depending on the roof’s pitch and the level of rainfall in the area.

How to Choose an Optimal Gutter Size:

To achieve a BS EN 12056-compliant gutter size, we calculate your Effective Roof Area (ERA) and multiply it by the rainfall intensity in your specific UK region.
