We all know that April showers are certainly not little, and not necessarily even in April anymore! But rainfall in spring is generally pretty heavy; this washes fine debris like silt and sand into your gutters which can easily form a blockage.
Wet sand and silt weighs a lot, and this puts the guttering brackets under unnecessary strain and can result in broken gutters, rather than blocked ones. It also provides a lovely bed for seedlings to take root, which we’re sure you can appreciate – isn’t a good thing.
