Regular maintenance ensures that they are free of obstructions and operate efficiently. It is essential to determine the size of your downpipes to match the roof's size to ensure proper drainage. This will ensure that the performance is optimal. Placement Gutters are designed to drain and collect rainwater. However, if they're damaged or poorly positioned the water may run down the sides of the house and get into the foundations and walls. This can cause structural damage, soil erosion and flooding, as well as damp crawlspaces and basements. Proper guttering and downpipe installation is vital to prevent this from happening, and is often controlled by building regulations. Downpipes are drainage pipes that connect to a spouting system or guttering. They redirect snow melting and rainwater (in cold climates) away from your house using gravity. They also protect the walls and foundations from water damage, and help prevent rotting fascia boards and leaks. The correct size of a downpipe is vital for the proper drainage system. Insufficiently sized downpipes can cause overflow, and when placed too close to the house, could increase the risk of flooding. The ideal size of the downpipe depends on roof size and pitch, and a 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. Metal options like galvanised steel or aluminium provide durability, corrosion resistance, and long-lasting durability under all weather conditions. Plastic alternatives like PVC and vinyl are lightweight, affordable, and easy to install, however they could be susceptible to UV deterioration in extreme sunlight. After the downp
