    Licensing for roofers working in Trenton

    New Jersey does not license roofing contractors. It requires them to register with the New Jersey Division of Consumer Affairs, and that requirement covers work in Trenton.

    Registration and licensure are not the same thing — a registration number records that a business completed a filing, and it sits alongside, not instead of, a permit and an inspection through Mercer County or the city.

    Storm history in Mercer County

    Trenton has no weather record of its own — NOAA records severe weather against counties, and the listings on this page put Trenton in Mercer County. These are weather records for the whole county, not an assessment of any building in Trenton.

    NOAA's Storm Events Database holds 151 severe-weather events recorded against Mercer County between 2016 and 2026: 120 thunderstorm wind events, 23 hail reports and 8 tornadoes.

    Of the 23 hail reports, 13 measured 1.00 in across or larger and 10 measured under an inch. The largest on record is 1.50 in (Ping Pong Ball) on July 6, 2020.

    The strongest wind gust in the record is 62 kt (about 71 mph), a measured gust, on April 1, 2023. The county record holds eight tornadoes over the same period.

    The busiest complete year in the record is 2019, with 35 events. The most recent event meeting this dataset's severity definition is a hail report measuring 1.00 in (Quarter - Half Dollar) on July 27, 2026. That one is a preliminary report and has not yet been through the quality-control review that produces the permanent archive.

    * The most recent data year is partial. NOAA publishes storm reports on a rolling basis and the final months are still being processed, so a low count in the last year is not evidence of a quiet year. The curated archive behind these counts runs through May 31, 2026; anything later sits in the preliminary block below.

    Notable events in the archive

    • Jul 15, 2023 -- Thunderstorm Wind (50 kt gust) -- $10K property damage reported
    • Apr 1, 2023 -- Thunderstorm Wind (62 kt gust)
    • Jul 29, 2021 -- Tornado (EF2)
    • Jul 6, 2020 -- Hail (Ping Pong Ball hail, 1.50 in)

    Selected by the dataset’s own rule rather than by editorial choice: the largest hail, the peak wind gust, the strongest tornado and the two costliest events by recorded property damage, deduplicated and newest first. Any dollar figure above is NOAA’s recorded estimate for that one event.

    Preliminary — not yet in the permanent archive

    10 preliminary storm reports have been filed for Mercer County since June 1, 2026: 9 thunderstorm wind events and 1 hail report. The largest hail in the window is 1.00 in (Quarter - Half Dollar), reported July 27, 2026.

    Preliminary reports covering 2026-05-31 onward come from National Weather Service storm reports filed as events occur. They have not yet been through the quality-control review that produces the permanent archive, and individual reports may later be revised, combined or withdrawn. NOAA Storm Prediction Center storm reports.

    What these counts cover. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported.

    “Significant” on this page means an event meeting any one of three tests: hail 1.00 in across or larger, a wind gust of 58 kt or more (the National Weather Service severe thunderstorm criterion), or any tornado. It is a severity definition used by this dataset and is not an official NOAA classification.

    The damage figure. $10,000 is the sum of NOAA’s recorded property-damage estimates across every event in Mercer County over the period — a county total, not a figure for any one property, any one building or any one claim. NOAA records these figures as estimates made at the time of reporting. They are not adjusted for inflation, and they are frequently absent or zero — a zero means nothing was recorded, not that nothing was damaged.

    Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Anything after that date comes from NOAA Storm Prediction Center preliminary storm reports and is labelled preliminary wherever it appears. Both are US Government works in the public domain.
