Roof valleys, or valley gutters, are a key piece of most gutter systems, directing water off the roof and down into the lower parts of the guttering with ease. Installing a good roof valley gutter guard is a fantastic way to protect this important part of your roof, lower the risk of blockages, and keep water flowing smoothly away from your home.
A roof valley is a section of metal flashing designed to join two separate roof sections, and is generally supported by steel or wood underneath.
Typically, the valley’s width can range from 185mm to 210mm of the return rise to the centre fold, resulting in an overall width of around 335mm to 385mm, accounting for the distance lost at the fold.
The rounded return rise should be at least 10mm higher than the flat section, as this acts as a final defence against backflow. It’s often best to opt for the wider section of the valley sheet, and don’t hesitate to request custom widths if needed.
Despite their obvious benefits, homeowners should be aware that roof valley gutters often pose their own specific issues, including:
Roof valleys naturally collect leaves, twigs, and other debris, which can easily clog gutters or rainheads below, leading to water overflow and the potential for costly damage.
Due to their slope and design, valleys direct a greater volume of water flow (including twigs, leaves, and other debris) during heavy rain, increasing the risk of gutters and rainheads becoming overwhelmed and blocked.
Due to the location of valleys on the roof, if the gutters or rainheads at the base of the valley are blocked, damaged, or unprotected, water can pool in the valley, leading to leaks and potential structural damage to the home.
