Due to the width and depth of box gutters, a different method of gutter guard installation is required. We use specially made ‘flat trims’ for permanently screwing gutter mesh to the roof edge. Our gutter guard is screwed to the metal cap that sits on top of the parapet wall (see Box Gutter Guard diagram).
Box gutters are becoming more common in modern residential roofing, prior to about the year 2000, they were primarily on commercial and factory roofs. Box gutters are “boxed in” all around, they have higher edges on all sides. The highest edge is the parapet wall, this completely conceals the box gutter from the ground.
Our Triple-G system is great for most fascia mounted gutters, but for box gutters, we don’t normally recommend the ‘curled in’ method. Because box gutters are prone to sudden internal flooding, we are regularly asked to install our gutter protection on these roofs. If your box gutters are flooding due to sudden heavy rain, feel free to call us immediately, we have dedicated staff willing to attend to your roof ASAP! We can clean out and repair old box gutter protection systems.
