During autumn, there is a need to have a fully functioning gutter system. To be sure you should pay close attention to them and look after them properly. The rain and dropping leaves may result in blockages leading to damp patches and leaks.
Problems with downpipes often manifest as leaks which do not resolve by cleaning. If you have cleaned the main system of guttering but still have a leak, it is probable that it is a problem with the downpipes.
Therefore, remove the elbow joint connection and see if there are any clogs in there. A garden hose or a plumber’s snake can be used for manually breaking the clog. Once it is broken, wash out the pipe to make sure all debris is removed before putting it back together. You should be doing checks on downpipes more regularly.
