Local Knowledge

Roofing, Siding & Window Insights for Cottage Grove

Cottage Grove requires a permit for a roof replacement, and we pull it as part of every job. One local quirk worth knowing: the wind exposure on the newer east-side developments and along the bluffs is harsher than the sheltered older neighborhoods, so we often recommend upgraded wind-rated shingles out there, the cost difference is small and the difference in a July storm isn’t.

Cottage Grove grew from a river-valley farming town into a south-Washington-County suburb, and its housing tells that story. The 1950s Thompson Grove development brought the first wave of ranch-style ramblers, and the city’s northside still holds most of that older stock, single-level ramblers and traditional, Craftsman-influenced homes. Newer planned subdivisions like Woodward Ponds (townhomes) and Calarosa (Craftsman two-stories and one-level villas) added homes with larger footprints and steeper roof pitches than the older ramblers. We bid each by its actual roofline, a steep Calarosa two-story and a low-slope Thompson Grove rambler are very different jobs.

Cottage Grove sits in the southeast metro where storms tracking up from the south regularly bring hail, the area took a significant hail event on August 11, 2023 and has been under severe-weather warnings roughly two dozen times in a recent twelve-month span. That’s why storm and hail-damage inspections and insurance-claim work are among our most-requested Cottage Grove services, alongside roof replacement, James Hardie and LP SmartSide siding, and window replacement on the area’s aging builder-grade units. Our office is minutes away in neighboring St. Paul Park, so we’re often on a Cottage Grove roof the same week you call.

In the Community

We Know Cottage Grove

Cottage Grove is home turf for us, our shop sits just up Highway 61 in St. Paul Park, so we’ve been working on these streets since day one. We know the older homes in Old Cottage Grove, the ramblers and split-levels in the original neighborhoods off 80th Street that went up in the 1960s and 70s, the 1990s two-stories around Hamlet Park, and the newer construction pushing east into the East Ravine area toward the river bluffs.

That mix matters for roofing. A lot of Cottage Grove’s original housing is now on its second or third roof, and plenty of the 1990s stock is right at the age where shingles start giving out, especially after a hail season. The newer homes east of Keats Avenue are younger, but big open lots out there catch the full force of wind coming across the fields.

When you call us in Cottage Grove, you’re not getting a crew that drove an hour to find you. We drive past these houses on the way to work.

Recent Storm Activity

Recent Storm Damage in Cottage Grove

Cottage Grove and the surrounding south Washington County area take hail regularly, storms tracking up the river valley have hammered this corner of the metro more than once in recent years, and we handled a steady run of local insurance claims after each round.

If hail has come through your neighborhood, get the roof looked at even if it seems fine from the ground. Hail bruises shingles without tearing them, and the leaks show up a year or two later, often after the insurance filing window has closed. We inspect for free, tell you straight whether it’s worth a claim, and meet the adjuster on your roof if it is.
