Most homes around Nelson and Tasman need their gutters cleared once or twice a year. Twice if you have trees near the house, with one clear in late autumn. Blocked gutters are rarely a gutter problem on their own, they are how water gets into fascia boards, soffits and framing.
Gutters are the least interesting part of a house and one of the cheapest to get wrong. Here is what actually matters.
How often is often enough?
For most homes around Nelson, Richmond and Motueka, once or twice a year. Which one you need comes down to one question: what is growing above your roofline?
- Trees close to the house, especially natives that drop year round. Twice a year, with one of those in late autumn.
- Some planting nearby but nothing overhanging. Once a year is usually fine.
- Nothing overhanging at all. You can often stretch longer, but still look at them annually.
If you are not sure, watch the gutters during the next serious downpour. That tells you more than any schedule.
Why blocked gutters are not really a gutter problem
This is the bit people underestimate. A blocked gutter does not simply overflow and dry out. Water that cannot reach the downpipe backs up under the roof edge, where it sits against timber that was never designed to be wet.
From there it gets into:
- Fascia boards, which rot from the back where you cannot see it
- Soffit linings, which stain and sag
- Cladding and the framing behind it
- Foundations and paths, where water is repeatedly dumped in one spot
By the time there is a visible mark on a ceiling or a wall, it has usually been going on for a season or more. That is why a clean costs so little relative to what it prevents.
Signs it has been too long
- Water spilling over the front edge in heavy rain
- Plants growing out of the gutter, which means there is enough soil up there to hold water
- Sagging between brackets, or the gutter pulling away from the fascia
- Staining or damp patches on the wall directly below a gutter run
- A downpipe that stays quiet while the others run
What a proper clean involves
Clearing the channel and walking away is half a job. The downpipes matter just as much, because a clear gutter feeding a blocked downpipe still backs up. A decent clean means the channel cleared, the downpipes flushed, the brackets and joints checked while someone is up there, and the debris taken away rather than tipped on your lawn.
