Regular maintenance keeps them clog-free and working effectively. It is important to size your downpipes according to the roof size for proper drainage. This will ensure that the performance is optimal. Placement Gutters are meant to take rainwater and drain it. However if they're damaged or placed improperly, water could be able to seep into the walls and foundations of a house. can cause structural damage, soil erosiveness flooding, damp crawlspaces and basements. To prevent this from happening, it's important to install guttering and downpipes correctly. This is often covered in the building regulations. Downpipes are the drainage pipes that connect to a spouting or guttering and let rainwater (and melting snow in cold climates) to the ground and away from the house through efficient gravity flow. They also protect the foundations and walls from water damage and help prevent rotting fascia boards and leaks. The right size of downpipe is vital for the proper drainage system. Oversized downpipes may cause overflow and, when placed too close to the home, can increase the risk of flooding. The ideal size of the downpipe depends on roof size and pitch and a general standard is to have one downpipe for 9m (30ft) of guttering. There are a variety of downpipe materials available, including metal, plastic, and vinyl. Metals such as galvanised metal and aluminium are strong and resistant to corrosion, making them resilient in the most extreme weather conditions. Plastics such as PVC or vinyl are lightweight and inexpensive. They are also simple to install. However, they can be susceptible to UV degradation in intense sunlight. Once the gutters and downpipes have been installed, seal them using high-quality siliconeized caulking.
