Blocked gutters and downpipes might seem like a minor issue, but ignoring them can lead to serious problems for any property. When rainwater cannot flow freely through these channels, it causes damage that can be costly and time-consuming to repair.

How Blocked Gutters and Downpipes Cause Water Damage
Gutters and downpipes are designed to direct rainwater away from the roof and foundation of a building. When these systems become blocked by leaves, dirt, or debris, water overflows and seeps into areas it should not reach. This can cause:
Roof damage: Water pooling on the roof can rot wooden structures, damage shingles, and lead to leaks inside the building.
Wall damage: Overflowing water runs down exterior walls, causing paint to peel, plaster to crack, and masonry to weaken.
Foundation problems: Water that pools near the foundation can cause soil erosion, cracks, and even structural instability.
