Gutters often show warning signs before a blockage causes serious damage. Overflow marks, sagging sections and plants growing from the channel all deserve attention.
During rain, watch for water spilling over corners or running down the wall instead of through the downpipe. After rain, check for damp patches, leaf piles and staining around the fascia.
Do not climb onto a roof to investigate without the right equipment. A professional inspection can clear the obstruction and identify loose brackets, leaking joins or downpipe issues at the same visit.
