Chance = odds, over work hours, of rain heavy enough to disrupt a roofing day. Not recommended is our call, not a rule — the risk to the work is real, so we'd wait; limited means it's workable with care. Either way it's your crew, so check the sky and radar before you commit.
This is today's snapshot. The next 7 days for your area — the closest point we forecast to your ZIP, with the reasons behind every caution and stop, refreshed each morning — are what the free Sunday brief delivers.

What controls a roofing day in Oʻahu
Around Oʻahu, roofing runs nearly year-round — Oʻahu sees year-round trade-wind warmth, wetter in winter, with windward showers that often skip leeward, so the call usually comes down to a dry deck and safe wind on the day, not the month.
Most of these thresholds trace to the manufacturer specs and industry standards cited above; where no published number exists, we use a clearly-labeled conservative cutoff. Either way the physics is the same anywhere. What's specific to Oʻahu is when they line up, which is exactly what the live area-by-area call at the top of this page tracks each day.
When roofing gets tricky in Oʻahu
Rain stays fairly steady month to month here, so a roofingday comes down to the daily forecast and which part of the metro you're in more than the season. It's rain and wind — not the calendar — that decide any given roofing day here. Source ≈10-yr ERA5 reanalysis (Open-Meteo), 2015–2024
Common questions
Can you roof in the rain in Oʻahu?
No — the deck and shingles have to be dry to work safely and to seal. A wet roof is a fall and slip hazard, and shingles laid wet won't bond. Our daily call flags when a real rain is likely during work hours.
How much wind is too much for roofing in Oʻahu?
Around 30 mph, gusts make shingles hard to control and loose material starts to fly — that's a stop; near 40 mph it's a hard stop. These are conservative safety lines we set — reusing an OSHA power-line figure as a proxy — not a specific general-construction limit. 20–30 mph is a work-with-care, secure-your-materials band.
Is it too cold to roof in Oʻahu in winter?
Below about 40°F asphalt shingles won't self-seal and get brittle to handle — GAF and Owens Corning call for hand-sealing then. Below the mid-20s we'd wait for brittleness and ice risk.
