Repair King has photographed and worked on roofs across Cottage Grove, from farmhouse-era homes near Old Cottage Grove to newer two-story builds off 80th Street and the East Ravine. We walk every slope after a storm, chalk-mark hail hits, pull the City of Cottage Grove roofing permit and upload the ice-and-water photos the city requires before final inspection.
Many Minnesota policies give you one year from the hail date. You shouldn't have to know that date, so we checked local weather and meteorology reports for you.
Local weather reports show 1.25″ hail near Cottage Grove on August 15, 2025. Here is the time left on that one-year mark.
One-year mark:
No 1″+ hail reported near Cottage Grove in the last 12 months. The last report was 1.25″ near Cottage Grove on August 15, 2025. If hail hits today, here is what one year really looks like:

Hail dates: local weather and meteorology reports near Cottage Grove. Winter: local weather records for Minneapolis-St. Paul, 30 winters, July 1996 to June 2026: an average of 107 days a year never get above 40°F (range 76 to 136). General information, not legal advice. Your policy's "Suit Against Us" section sets your actual deadline, and some claims get two years (Minn. Stat. §65A.01) instead of one (§65A.26).
Cottage Grove became a suburb almost overnight: in 1958 Orrin Thompson Homes bought the Belden Farm west of Highway 61, and by spring 1960 it had platted 1,164 lots in eight Thompson Grove additions. The city then added its biggest share of homes in the 1990s, so a Cottage Grove roofer works on 60-year-old ramblers and 30-year-old two-stories on the same day.
Before Thompson Grove, Cottage Grove was a farm township of 833 people (1950). Ranch-style ramblers pushed that to 4,850 by 1960 and 13,419 by 1970, according to the Washington County Historical Society and the city's comprehensive plan. The city's own historic preservation report lists Thompson Grove as one of four areas worth considering for a future local historic district, alongside Old Cottage Grove, Langdon and Lower Grey Cloud Island. None of the four is a designated district today, so a re-roof there goes through the normal building permit, not a design review.
Those first-generation ramblers have simple, low roofs, and after more than 60 years many have already been re-roofed more than once. Before we price a tear-off we count the layers: the Minnesota Residential Code, as summarized in the city's roofing handout, doesn't allow a new layer over a roof that already has two. We also look hard at 60-plus-year-old decking, chimneys and attic ventilation, because those are the things a tear-off exposes.
The second wave looks nothing like the first. The largest single decade of home building in Cottage Grove was the 1990s (22.2% of homes, per the city's 2024 housing study), followed by the 2000s. Those homes are larger, with more hips, valleys and roof-to-wall flashing, and many are now on their first or second replacement. The photo here is from one of them: a ridge-top view over a newer Cottage Grove street during a 2023 hail inspection.
Cottage Grove was platted in 1871 and grew from a river-bluff farm town into a city of more than 38,000, and the roofs reflect nearly every decade in between. What we look for changes block by block.
The historic core near the 1871 John P. Furber House and Cordenio Severance House has some of the oldest roof lines in the city, often with multiple layers of old shingles and chimneys that need fresh step flashing before a re-roof passes inspection.
Established neighborhoods built up around Cottage Grove's two largest parks. Mature tree cover means more moss, debris in valleys and ice damming at the eaves in winter.
The city's newer planning area east of Ideal Avenue, built out under the 2006 East Ravine master plan. Roofs here are younger but often have complex hip-and-valley designs that catch wind-driven hail differently than a simple gable.
Homes along the river bluff and near Grey Cloud Island see more open wind off the Mississippi River valley. We check ridge caps and rakes closely on these lots after a wind event.
Cottage Grove is overwhelmingly single-family: detached houses make up 91% of owner-occupied homes, and the median home was built in 1988. About 40% of the housing stock predates 1980, and the biggest building decade was the 1990s, so roof age and roof style change sharply from one neighborhood to the next.
| Local factor | What we see in Cottage Grove | Why it matters for repairs |
|---|---|---|
| Housing eras | 8.8% of homes built in the 1950s and 14.2% in the 1960s, mostly Thompson Grove-era ramblers; 16.3% in the 1970s | Older roofs often carry more than one layer and need a full tear-off, deck check and new ice barrier |
| 1990s–2000s growth | 22.2% of homes built in the 1990s and 15.0% in the 2000s, the largest share of any decades | Many of these complex hip-and-valley roofs are reaching the end of their first or second shingle cycle |
| Home type & tenure | 91% of owner-occupied homes are single-family detached; 25.7% of rentals are single-family houses (metro: 11.6%) | Lots of landlord-owned houses, so we send dated photo reports owners can review without climbing a ladder |
| Roofs & siding we see | Architectural asphalt shingles on most homes we inspect, with vinyl and painted lap siding and aluminum window wraps | Soft metals and lap siding show hail dings clearly, so we check all four elevations, not just the roof |
| Trees | The city owns and maintains about 14,500 boulevard trees and treats its ash trees on a three-year cycle | Owners can't trim boulevard trees themselves; if a city tree is over your roof, call Public Works before we schedule |
| River corridor | The city's southwest corner is inside the Mississippi River Corridor Critical Area, with homes on the bluffs and along River Acres and Grey Cloud | Open river wind hits ridges and rakes; tree removal or grading near a bluff can need an MRCCA review |
Every Cottage Grove property in our CompanyCam records is a home, so these are four of the best-documented. All photos were taken by our crews on site; we don't show names or house numbers.
Cottage Grove sits in the Mississippi River valley southeast of St. Paul, in a corridor that has taken hail on 9 separate days of 1 inch or larger since 2015. Local storm reports put 1.25" hail near our Cottage Grove job sites on August 15, 2025, and the largest hail recorded near those same properties since 2015 was 1.75" on September 20, 2022. The most recent damaging wind report nearby was a 64 mph gust on August 29, 2024. Hail that size can bruise shingles and dent soft metal even when the roof looks fine from the driveway, and gusts in the 60s lift tabs and ridge caps.
| Date | Type | What was reported | What to check |
|---|---|---|---|
| Aug 15, 2025 | Hail | 1.25" hail reported | Shingles, roof vents, gutters, siding, window screens |
| Sep 19, 2024 | Hail | 1" hail reported | Shingles, roof vents, gutters, siding, window screens |
| Aug 29, 2024 | Wind | 64 mph wind gust measured | Missing or creased shingles, ridge caps, flashing, siding |
| Jun 12, 2024 | Hail | 1" hail reported | Shingles, roof vents, gutters, siding, window screens |
| Aug 11, 2023 | Hail | 1" hail reported | Shingles, roof vents, gutters, siding, window screens |

Our free Roof & Storm Report looks up hail and wind history for your exact address, not just the city.
Photos taken by Repair King crews at Cottage Grove properties. Dates are the capture dates from our job camera.
Yes. The City of Cottage Grove issues residential roofing permits through its online portal, and the 2026 fee table lists a flat $121 fee for a residential re-roof. Since May 19, 2025, ice-and-water barrier photos must be uploaded to the permit before the final inspection can be scheduled.
The City of Cottage Grove Building Division requires a permit for residential roof replacement. Repair King pulls it under our Minnesota contractor license (BC695228).
Cottage Grove requires ice-and-water barrier photos to be uploaded to the city's online permit portal before the final inspection can be scheduled. The city also stopped doing on-site weather barrier inspections on May 19, 2025, and asks for photos instead. We take and submit these photos as part of every re-roof, so nothing holds up your final sign-off.
Homes in the city's southwest corner fall inside the Mississippi River Corridor Critical Area overlay. A straight re-roof doesn't change a house's footprint, but tree removal, grading or additions near a bluff can need an MRCCA administrative review. We check the city's MRCCA map before we plan staging on those lots.
Cottage Grove was platted in 1871 and stayed a farm township until the late 1950s. It now covers everything from Old Cottage Grove's 19th-century core to newer homes in the East Ravine, plus river-bluff lots along the Mississippi and Grey Cloud Island.
Cottage Grove was platted in 1871 by John and Joseph Furber, and the 1871 John P. Furber House and 1917 Cordenio Severance House are both on the National Register of Historic Places today, along with the Grey Cloud Lime Kiln, which dates to at least 1846 and overlooks Grey Cloud Channel. Hamlet Park, at more than 150 acres, is the city's largest park, and Highlands Park's 65 acres include an ice rink and more than four miles of paved trail. The 3M Cottage Grove chemical operations plant on Innovation Road remains one of the city's largest employers. Our crews have worked roofs from that historic core out to the newer East Ravine, so we know what a Cottage Grove inspection needs to cover before we set a ladder.
Start with an inspection, not a decision. A damaged shingle does not automatically mean a roof needs to be replaced. What matters is what the inspection actually finds on the roof, siding, gutters and windows.

No. The city's historic preservation report lists Thompson Grove as a candidate for a future local historic district, but Cottage Grove has no designated historic districts today. A re-roof goes through the normal building permit.
Usually not. Minnesota code doesn't allow a new layer over a roof that already has two, and many 1950s and 1960s Cottage Grove ramblers have already been re-roofed at least once. We count the layers during the inspection and tell you what we find.
Yes. We regularly work on homes near the historic Old Cottage Grove core, where roofs often carry multiple layers of old shingles and chimneys need fresh flashing before a re-roof will pass city inspection.
Yes. Homes along the river bluff and Grey Cloud Island see more open wind, so we pay close attention to ridge caps and rakes. Parts of the city's southwest corner are in the Mississippi River Corridor Critical Area, and we check that map before planning work on bluff lots.
No, and neither can you. The City of Cottage Grove owns its boulevard trees, and residents aren't allowed to trim or remove them. Call Public Works at 651-458-2808 and the City Forester will evaluate it.
