Hail Risk: Hawaii almost never experiences hail at sea level, though rare hail events can occur at higher elevations on Maui and the Big Island during strong thunderstorms.
Hurricane Risk: Hawaii sits in the central Pacific hurricane basin and faces significant tropical cyclone threats. Hurricane Iniki (1992) devastated Kauai, and Hurricane Lane (2018) brought record rainfall.
Tornado Risk: Hawaii averages about 1 tornado per year, usually brief waterspouts that come ashore, posing minimal widespread roofing risk.
Wind Damage: Trade winds, Kona storms, and tropical cyclones generate sustained strong winds that stress roofing systems, particularly on windward exposures.
Sources: Storm risk data compiled from NOAA Storm Prediction Center, National Hurricane Center, NCEI Billion-Dollar Weather Events, and National Weather Service local forecast offices. Risk levels reflect historical frequency and severity of events in this area.

Common Materials
Hawaii has the highest roofing costs in the nation due to material shipping from the mainland, limited contractor availability, and extremely high labor and living costs. Trade winds, salt air corrosion, and hurricane exposure all require premium materials.
Insurance Tip: Hawaii homeowners insurance is very expensive, especially for properties in hurricane and lava zones. The Hawaii Hurricane Relief Fund provides supplemental coverage for windstorm damage.
Best Season: Year-round work is possible, though the drier months (April–October) are preferred. Hurricane season (June–November) can cause scheduling disruptions.
