This directory holds two roofing listings for Sycamore, Illinois. None of them has a Google rating matched to it yet, so what follows is contact detail rather than reputation data.
All of them are recorded in DeKalb County. Roofing permits and inspections are issued locally rather than by the state, so a re-roof in Sycamore goes through DeKalb County or the municipality's own building department, whichever holds jurisdiction at the property.
Hiring a roofer in Sycamore: what this page knows
Illinois licenses roofing contractors at state level, so a Sycamore roofer should hold a current state license before quoting; the Illinois roofing license rules set out the class and how to check it.
Illinois's peak severe-weather season: April–July. The Illinois storm center lists any National Weather Service alert active right now. NOAA's Storm Events Database holds 177 severe-weather events for DeKalb County between 2016 and 2026 — the county the listings on this page put Sycamore in. The most recent event meeting the dataset's severity definition was a hail report measuring 1.00 in (Quarter - Half Dollar) on August 21, 2026, a preliminary report that has not yet been through NOAA's quality-control review.
We have not modeled a cost index for Sycamore. The national baseline puts a full roof replacement at $5,625–$27,000 and a repair at $250–$3,500; local labor, permit fees and access move both.

Licensing for roofers working in Sycamore
Illinois licenses roofing contractors at state level, and the requirement applies to work in Sycamore. The license is issued by the Illinois Department of Financial and Professional Regulation.
A state license is not a substitute for local rules: the job still needs a permit and an inspection through DeKalb County or the city, and some municipalities require their own contractor registration on top of the state license.

* 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
- Apr 4, 2023 -- Hail (Softball+ hail, 2.75 in)
- Aug 9, 2021 -- Tornado (EF1)
- Aug 10, 2020 -- Thunderstorm Wind (78 kt gust)
- Jun 14, 2017 -- Thunderstorm Wind (55 kt gust) -- $5K property damage reported
- Jun 14, 2017 -- Thunderstorm Wind (55 kt gust) -- $2K property damage reported
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
14 preliminary storm reports have been filed for DeKalb County since June 1, 2026: 12 thunderstorm wind events and 2 hail reports. The largest hail in the window is 1.00 in (Quarter - Half Dollar), reported June 24, 2026. The strongest gust reported is 64 kt (about 74 mph), on June 11, 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. $11,000 is the sum of NOAA’s recorded property-damage estimates across every event in DeKalb 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.
