Regular maintenance ensures they are free of clogs and work efficiently. The size of your downpipes should be in line with the size of your roof is vital to ensure proper drainage of water. This will ensure that the performance is optimal. Placement Gutters are designed to drain and collect rainwater, but if they're damaged or not properly placed they can allow water to flow down the sides the house and then seep into the foundations and walls. This can lead to structural damage, soil erosion, flooding and damp crawlspaces, and deterioration of the roof. To avoid this from happening, it is essential to install guttering and downpipes correctly. This is often regulated in building regulations. Downpipes are the drainage pipes that connect to a guttering or spouting, and let rainwater (and melting snow in cold climates) down and away from the home through efficient gravity flow. They protect walls and foundations against water damage, and help prevent the fascia board from rotting and leaking. The right size of downpipe is crucial for the proper drainage system. Oversized downpipes may cause overflow, and if placed too near the house, could increase the risk of flooding. The ideal size of the downpipe depends on the size of the roof and pitch and a good rule of thumb is to have one downpipe for 9m (30ft) of guttering. There are a variety of materials for downpipes including plastic, metal and vinyl. Metals such as galvanised metal and aluminium are strong and resistant to corrosion, making them resilient in the most extreme weather conditions. Plastic alternatives like PVC and vinyl are light affordable, cost-effective, and simple to install, however they could be vulnerable to UV deterioration in harsh sunlight. After the d
