Short answer: Yes — hail fell in Douglas County on August 15, 2026. The Douglas County Sheriff's Office and South Metro Fire Rescue documented two to three feet of accumulated hail under floodwater at Meridian Boulevard and Maroon Circle, west of Parker. The largest reported stone size in the corridor was 1.75 inches, near Lone Tree.
Saturday afternoon, August 15, 2026, a slow-moving storm dropped enough hail on the south metro that it piled up under floodwater deep enough to strand cars. If you live in Parker, Lone Tree, Highlands Ranch or anywhere along the I-25 corridor, you have probably seen the photos by now — and probably a door-hanger too.
We're a Parker-based roofing team, so this one landed in our own county. Here is the actual report record, including the part that cuts against the dramatic number everyone is quoting.
Was There Hail in Douglas County on August 15, 2026?
Yes. Storms moved through the south metro around 2:30 p.m. that Saturday, and both the Douglas County Sheriff's Office and South Metro Fire Rescue documented hail on the ground in Douglas County, with photographs. CBS Colorado reported it the same day.
We need to correct something we published ourselves. Our August 13 post said no Douglas County hail report existed for August 13 through 15. That was true for August 13, and it was true against the National Weather Service and mPING report record on the day we wrote it. It is not true for August 15. We have corrected that post, and we are saying so here instead of quietly editing it — a roofing company that revises its storm claims in the dark is not one you should let on your roof.
What Actually Happened at Meridian and Maroon Circle?
The most striking report came from Meridian Boulevard and Maroon Circle, in the Meridian area just west of Parker. South Metro Fire Rescue described two to three feet of hail accumulated beneath floodwaters at that intersection, and both South Metro Fire Rescue and the Douglas County Sheriff's Office published photographs of it.
Between 2:30 and 4:00 p.m., South Metro Fire Rescue carried out seven water rescues at intersections in both Douglas and Arapahoe counties, east of I-25 and as far east as Parker Road. Aurora Fire Rescue reported more than fifteen 911 calls in the same window, with vehicles trapped and homes taking on water, including a rescue at Alameda Avenue and South Havana Street. Significant hail was also reported in Ken Caryl, on the southwest side of the metro.
How Big Was the Hail — and Is “Three Feet of Hail” the Same as Three-Foot Hail?
No, and this is the most misunderstood number from this storm. Two to three feet describes accumulation — how deep the ice piled up on the ground after it fell, drifted, and got shoved around by floodwater. It does not describe the size of the stones that hit your shingles.
The largest individual stone size reported in the corridor that day was 1.75 inches — golf ball size — near Lone Tree, with the same size logged near Centennial and Cottonwood. That figure comes from a third-party hail-report aggregator rather than a National Weather Service storm report, so we are handing you the source along with the number. If we see an NWS or Storm Prediction Center report with a larger verified stone for August 15, we will update this page and say what changed.
Your roof does not care how deep the pile got. It cares about stone size, wind speed, the angle the stones came in at, and how old and brittle the shingles already were. Three feet of drifted pea-size hail can leave a roof untouched. A short burst of golf balls can end it.
Did Parker, Lone Tree or Castle Rock Get Hit?
Partly — and the honest answer is different for each town.
- Parker — the Meridian accumulation and the water rescues running east to Parker Road put this storm squarely on Parker's doorstep. We have not seen an individual stone-size report from inside Parker itself for August 15.
- Lone Tree — the 1.75-inch golf-ball report near Lone Tree is the largest stone size logged anywhere in the corridor that day.
- Castle Rock, Castle Pines, The Pinery and Franktown — named in the National Weather Service special weather statement issued at 1:08 p.m., alongside Denver, Aurora, Lakewood, Centennial, Highlands Ranch, Littleton, Englewood, Greenwood Village and Lone Tree.
That last line needs care, because it is the thing most likely to be misquoted at your front door. A special weather statement forecasts what a storm could do along its track. Being named in one is not an observation that hail fell on your town. Some of those towns were hit — but the list is not the proof, and a map with a colored blob over your street is not the proof either. Ask which report it is based on.
Does a Nearby Hail Report Mean Your Roof Is Damaged?
No. A hail report is a single observation: someone reported ice of a certain size, at a certain place, at a certain time. Colorado storms are hyper-local — two streets in the same neighborhood routinely come out differently, and a report three miles away is context, not a verdict on your shingles.
The honest answer, more often than people expect, is that the roof is fine. We say that out loud on inspections. If you want to know what you are looking for first, we have written up what hail damage actually looks like and how to read storm reports without panicking.
What Should You Do in the Next Two Weeks?
- Write down the date and rough time you heard hail — Saturday, August 15, mid-afternoon. That detail matters later far more than people expect.
- Look from the ground: dented gutters, downspouts, metal roof vents, AC fins, and granules washed into the splash blocks. Don't get on the roof.
- Photograph anything you find with something in frame for scale. If you took on water, photograph that separately — flooding and roof damage are two different questions.
- Get a roof-level inspection from someone who will put it in writing that the roof is undamaged if it is.
- Don't sign anything at the door under time pressure. Read how to vet a roofer and spot a storm chaser first.
If there is damage, the next question is usually repair or replacement, and we walk through how that call gets made in repair vs. replace after Colorado hail. If you are documenting it yourself, how to document hail damage covers what to capture and when.
How Do You Tell a Local Roofer From a Storm Chaser?
The short version: a storm-chasing crew appears within days of a hail event, works out of a rental truck, and is gone before the first winter. A local company was already here before the storm and will still be here when a flashing detail leaks in three years.
Upstream Roofers works out of Parker — this storm hit our own county. We serve Parker, Lone Tree, Castle Rock, Castle Pines, Highlands Ranch, Centennial and the rest of the south metro, with the same project managers and crews on every job here.
Where the Long-Term Hail Record Lives
One afternoon is not a pattern. Our Storm Almanac publishes the full NOAA hail record, county by county, for every town we serve — so you can see how often hail actually hits Douglas County and how big it typically gets. NOAA's national database publishes on a multi-month lag, so this August storm will not appear there for a while. That is expected, not a gap in the data, and anyone showing you a NOAA record for August 2026 right now is showing you something else.
If this pushes you toward a stronger roof rather than the same one again, Colorado's new hail-resistant roof grant and what Douglas County's code requires on a replacement are both worth reading before you sign anything.
