Summer and shoulder seasons
Longer days and more settled weather mean fewer delays. It's also when everyone wants a roofer, so book ahead.
Winter
Short days and wet, windy spells mean more days lost. But roofers stage the strip-off so the house is closed in every night. If your roof's failing, don't hang on for summer.
Wind
On a high-wind day, nobody's handling sheets up top, whatever the season. See Wellington wind zones.

What is the windiest time of year in Wellington?
Spring. NIWA's regional climatology says spring is generally the windiest season right across the region, and autumn has the fewest strong winds 1. That matters because nobody handles sheets at height on a high-wind day.
| Season | Re-roofing conditions |
|---|---|
| Spring (Sep–Nov) | Windiest season [[niwa]] |
| Summer (Dec–Feb) | Longer days, more settled spells |
| Autumn (Mar–May) | Fewest strong winds [[niwa]] |
| Winter (Jun–Aug) | Shorter, wetter days; more weather delays |
Can you re-roof in winter in Wellington?
Yes. Roofers only open up what they can close the same day, and a failing roof shouldn't wait. Just expect more weather days in the schedule 2.
Frequently asked questions
How far ahead should I book?
Ask about lead times when you ask for a quote. They change through the year.
