Why spouting earns its keep in Whangārei
Winter does the steady work
June, July and August bring the most rain days, out of 192 a year at Whangārei Aero. That's when blocked outlets and sagging runs give themselves away, usually as water running down the cladding.
Storms bring the volume
The March 2007 Northland rainstorm dropped up to 450 mm in 36 hours in some areas, and the July 2008 storm flooded Whangārei's CBD. Spouting that copes with winter drizzle can still overflow in a downpour like that if it's undersized or short of downpipes.
Salt along the harbour
BRANZ says homes within 500 m of the coast or harbour, or 100 m of a tidal estuary, sit in exposure Zone D. Spouting is tucked under the roof edge, where rain doesn't rinse the salt off, and the metal roofing Code of Practice says those unwashed spots corrode faster than the open roof.
Dry spells let grit build up
Whangārei's longest recent dry spell ran 42 days, from 5 December 1990 to 15 January 1991. During a long dry stretch, leaves, dust and salt settle in the spouting, and the first heavy rain sweeps the lot to the outlets at once.
Easterly winds
The airport's record gust came from the east, 122 km/h on 28 July 1982, and tropical storms usually bring strong easterlies. Brackets need fixing into sound fascia, especially on the exposed side of the house.
Older spouting and asbestos
WorkSafe lists gutters and downpipes among the places asbestos cement can be found in homes built before 2000. On an older Whangārei house, have heavy grey spouting tested before anyone saws through it or pulls it down.
Fix it, replace it or upgrade it?
A leaking joint or a loose bracket is a job for spouting repairs.
If it overflows even when it's clean, ask about bigger spouting or another downpipe. Replacing like for like won't change how much water it can carry.
If steel spouting has rusted through near the coast, swapping it for a product suited to the exposure zone beats patching it again. Where trees drop leaves, gutter guards can help, though they still need checking.
What makes a Whangārei spouting job bigger or smaller
A like-for-like run on a single-storey house is the simple end. Coastal-grade material near the harbour, extra downpipes for storm downpours, rotten fascia and two-storey access all add work.
Ask for a written quote that names the material and its exposure rating, the number of downpipes, bracket spacing, removal of the old spouting and the fall protection. Our guide to reading a roofing quote has more.
What to ask before you agree to a spouting quote
- Is my house in exposure Zone D, and are this spouting and its brackets rated for it?
- Will it carry a tropical downpour, or should we add a downpipe?
- What will the brackets be fixed into, and is the fascia sound enough to hold them?
- Where do the downpipes discharge, and are they connected to stormwater?
- Could the old spouting contain asbestos, and how will you handle it?
- Is taking away the old spouting included in the price?
What you can check yourself
You can
- Watch from under cover in heavy rain to see where water spills over.
- Clear the downpipe outlets and grates you can reach from the ground.
- Look for rust spots, drips at joins and stains on the cladding below.
- Note anything that overflowed last winter and get it sorted before December.
Leave to a roofer
- Cleaning spouting at height
- Replacing brackets, joins or full runs
- Adding downpipes or bigger outlets
- Removing anything that might be asbestos cement
Our pick for Whangārei spouting
We'd get spouting checked and cleaned in late spring, before the storm season starts in December. If it's overflowing even when clean, we'd pay to fix the capacity rather than replace like for like. Near the harbour, we'd choose spouting and brackets suited to the zone and keep the paperwork showing what was used.
