Blocked gutters are one of the most common — and most preventable — causes of damp and roofline damage. How often you should clear them depends on your surroundings.
Why Gutter Cleaning Matters
When gutters block, rainwater overflows behind the fascia and down the walls, leading to damp, rot and, over time, damage to the roof structure itself.
How Often to Clean
As a rule of thumb, clear gutters at least twice a year — in late autumn once leaves have fallen, and again in spring. Properties surrounded by trees may need clearing three or four times a year.
Tip
Clean gutters shortly after the last leaves fall — that single autumn clear-out prevents most winter overflow problems.
