Specialist repair of leaking or damaged box gutters. We restore proper drainage, prevent water damage, and extend the lifespan of your roof or conservatory.
A leaking box gutter is one of the most common issues homeowners face with conservatories. Box gutters are designed to handle large volumes of rainwater where the conservatory roof meets the house wall or another roof section. However, over time, several factors can cause leaks to appear.
One of the main reasons is blocked gutters and debris build-up. Leaves, moss, and other debris can quickly block the narrow channels of a box gutter. When water can’t drain away properly, it overflows or seeps through joints, leading to leaks both inside and outside the conservatory.
Another common cause is failed seals or joints. The joints and seals in a box gutter system can deteriorate with age or temperature changes. As these seals break down, water finds its way through tiny gaps, resulting in a leaking box gutter that worsens with every downpour.
Poor installation can also cause problems. If your conservatory was fitted with incorrect falls, or if the flashing wasn’t installed properly, leaks can develop early. Even a small installation error can create a weak point where water collects and penetrates.
Corrosion or material fatigue is another factor. Over time, metal box gutters can corrode, and uPVC ones can warp or crack, especially under constant exposure to sun and frost. Once the surface is damaged, leaks are inevitable.
Lastly, thermal movement and structural shifts play a role. Conservatories naturally expand and contract with changes in temperature. This movement can stress the gutter joints and cause separation, leading to persistent leaks that are often hard to notice until water damage becomes visible.
