The short answer
Common signs include overflow during rain, visible leaves or plants, staining below the roofline, sagging sections, water collecting near walls, damp around eaves and downpipes that release little water during a shower. Some symptoms can also indicate damaged or incorrectly installed drainage.
Key takeaways
- Overflow is the clearest warning sign.
- Staining may reveal repeated water movement.
- Plants indicate long-standing organic build-up.
- Cleaning cannot correct damaged gutters or underground blockages.
1–2: overflow and visible debris
Water spilling over the front or back of a gutter suggests that the channel or outlet cannot move rainfall fast enough. Leaves, roof grit, nesting material and compacted organic matter are common causes. Plants growing in the channel indicate that debris has held moisture long enough to support roots.
3–4: staining and sagging
Dark marks on fascia boards, walls or paving can show where overflow repeatedly travels. A sagging gutter may be carrying excessive wet debris, have failed brackets or have an incorrect fall. Cleaning removes weight and obstruction but does not repair damaged supports or alignment.
5–7: pooling, damp and weak downpipe flow
Water collecting beside walls, damp around eaves and little visible discharge from a downpipe during rain can all justify inspection. These signs do not prove the gutter is the only problem; roof defects, underground drains and poorly directed outlets may also be involved.
What to do before winter
Take a look from ground level before Cape Town’s sustained winter rain and after heavy leaf fall. Do not lean ladders against unstable gutters or climb onto wet roofs. Send clear photographs and show us where the overflow happens so we can arrive prepared.
