For roof protection, gutters should be checked at least twice a year, and more often if you have overhanging trees. Once before the rainy season or winter, to make sure they’re clear, and once after heavy leaf fall. Blocked gutters cause water to overflow and sometimes push back under roof edges, leading to leaks and rot.
During checks, remove leaves, twigs and mud, and ensure downspouts are not clogged. Look at how water flows in a rainstorm; if it spills over in certain spots, those areas need attention. Secure any loose sections of guttering so they don’t sag and collect standing water.
You don’t always need a professional for basic cleaning, but if your roof is high or access is unsafe, it’s worth hiring someone. Clean, well-attached gutters are a small maintenance task that dramatically lowers the chance of water-related roof problems.
