LYSAGHT Guttering on your home or shed is important for a number of reasons. They collect valuable rain water which you can store in a Rainwater tank on your property. Gutters prevent water pooling around the perimeter of your shed, they stop the rain from just running off your roof sheets and onto the ground outside your roller doors or PA door making things very wet around the shed. Gutters collect the rain water from the roof and divert it into the downpipes which when connected to storm water pipes, prevents run off from your shed damaging your home or your neighbours property.
