Skylights under Tauranga's weather
Lots of sun, so size it modestly
With more than 2,200 sunshine hours a year, a big glazed skylight can overheat a Tauranga room in summer. For a hallway, bathroom or laundry, a small tubular skylight (a dome on the roof feeding a reflective tube) often gives enough light with far less heat.
Clear winter nights bring condensation
The airport logs 54.6 ground frosts a year, which tells you how often winter nights turn clear and cold. On those nights warm, damp air inside hits cold glazing and drips. Double glazing and a bathroom extractor fan help, and a drip in winter isn't always a leak; see condensation or a leak?.
Gusts and tornadoes test the flashing
Tauranga is the gustiest of NIWA's Bay of Plenty stations, and tornadoes have damaged homes at the Mount, Pāpāmoa and Welcome Bay. A skylight's frame and flashing take wind load like the rest of the roof, so it needs fitting exactly to the maker's instructions for your roof profile.
Hail and brittle glazing
Hail is rare, about 1 day a year at the airport, but the May 2009 storm in the western Bay of Plenty dropped stones up to half the size of golf balls. WorkSafe lists skylights among the brittle roof parts nobody should walk on, which is one more reason to leave any skylight work to a roofer.
New skylight, or fixing an old one?
A leaking skylight is usually a flashing or seal problem rather than the glass, and re-flashing is a standard repair. If an old plastic dome has gone brittle or cloudy, swapping it for a comparable unit in the same opening generally falls under the Schedule 1 exemption, so no building consent is needed.
Cutting a new opening is different, because it changes the roof structure and the weathertight shell. Ask Tauranga City Council, or have the roofer confirm in writing, whether yours needs a consent before work starts. If it does, it's restricted building work and an LBP must do or supervise it.
Near the harbour or the surf, ask whether the skylight's frame, flashing kit and fixings suit your exposure zone. Our national skylights page compares the main types.
What makes a skylight job bigger or smaller
Tubular or glazed, the size, whether it opens, your roof material (tile takes more work than longrun), the length of shaft down to the ceiling and any electrics all change the size of the job. The quote should name the exact unit, the flashing kit for your roof profile, and who makes good the ceiling inside.
Questions for a Tauranga skylight installer
- Tubular or glazed for this room, and what size, given how much sun we get?
- Is the glazing double glazed or low-e, to cut summer heat and winter condensation?
- How will you flash it into my longrun, tile or decramastic roof?
- Are the frame, flashing and fixings suited to my exposure zone near the coast?
- Does a new opening here need a building consent?
- Who warrants the installation, separately from the product itself?
What you can check, and what to leave
You can
- Note whether drips appear during rain (likely a leak) or on cold, dry mornings (likely condensation)
- Run the extractor fan and open a window after showers
- Wipe the inside of the glazing and check the ceiling around it for stains
Leave to a roofer
- Anything on the roof, including cleaning the outside of a skylight
- Re-flashing, resealing or replacing a dome
- Cutting a new opening
Our pick for a Tauranga home
For a dark hallway or bathroom, we'd start with a tubular skylight: less heat in summer, less glass to fog in winter, and a smaller hole in the roof to keep watertight. For a living area that needs real daylight, we'd choose a double-glazed roof window from a roofer who fits that brand often, and get the consent question answered before anyone cuts the roof.
