Lake Waconia is the tenth-largest lake in Minnesota
Lake Waconia covers roughly 3,080 acres of surface area — the tenth-largest lake in Minnesota and the anchor of Carver County's fastest-growing city. Homes on the south, east, and west shores trend toward DaVinci Bellaforté Slate, DaVinci Multi-Width Shake, CeDUR Walden cedar shake, stone-coated steel, and CertainTeed Presidential Shake TL at first roof replacement. Joe walks every Lake Waconia install over $40,000 before our crews start. Standing on the open water of a 3,080-acre lake, these roofs see more wind exposure than the typical Twin Cities home — the material choice matters.

Waconia housing stock
Three Waconias: historic downtown, lake homes, ISD 110 subdivisions
Waconia was platted in 1857 and grew up around the south shore of Lake Waconia. Our project mix splits into three distinct sets of homes: the 1850s-1880s historic downtown commercial blocks and cottages, the lake homes ringing 3,080-acre Lake Waconia (including Coney Island, the historic resort island), and the 1990s-2010s subdivisions inside Waconia Independent School District 110. Each one needs a different scope.

Historic downtown 1850s-1880s
Slate preservation + cedar-shake re-do
Downtown Waconia's historic commercial block — the 1860s-1880s buildings along Main Street and the surrounding residential blocks — needs a different scope than a 1990s subdivision. Original slate that's still sound can run another century if the flashings, ridge caps, and underlayment are rebuilt. Cedar shake homes from the period typically need a full tear-off and CeDUR Walden, DaVinci Multi-Width Shake, or matched natural cedar to keep the silhouette. Joe walks every historic- downtown Waconia property before we scope.

Lake Waconia + Coney Island
Lake homes ringing 3,080 acres
Lake Waconia lake homes — south shore, east shore, west shore, plus the historic Coney Island resort properties — are the premium-material side of our Waconia mix. Typical roof size 35 to 60 squares, with full wind exposure off the open water. DaVinci Bellaforté Slate, DaVinci Multi-Width Shake, CeDUR Walden, CertainTeed Presidential Shake TL, and stone-coated steel are the five products that dominate. Shoreland-overlay setback paperwork submitted before we order materials.

ISD 110 subdivisions
1990s-2010s buildout, first or second roof
Waconia Independent School District 110 anchors the fastest-growing suburb in Carver County — much of the housing stock outside the historic core is 1990s through 2010s subdivisions. Most of these homes are first or second roof-replacement age. CertainTeed Landmark Pro, Malarkey Vista AR, and Atlas Pinnacle Pristine are the three lines we install most often. Class 4 impact- resistant upgrades qualify for 10 to 30 percent insurance premium discounts in Carver County.
2026 Waconia pricing
Waconia roof, siding + window pricing
Most Waconia ISD 110 subdivision roofs run $16,000 to $32,000 for architectural asphalt in 2026. Lake Waconia lake homes with DaVinci synthetic slate land between $112,500 and $227,500 on 45-65 square roofs at our installed rate of $2,500 to $3,500 per square. Re-siding an ISD 110 home runs $22,000 to $80,000, and a full window replacement runs $20,000 to $70,000. Written line-item quotes within 48 hours.

Why Waconia
Why Waconia homeowners choose Modex over other contractors
Three things separate us for Waconia homeowners: five shingle lines plus DaVinci, CeDUR, and stone-coated steel for lake homes; Joe Dvorak personally walks every Lake Waconia install over $40,000 and every historic-downtown property; and every residential install carries a lifetime workmanship warranty — transferable on premium product lines.

Lake-corridor materials
DaVinci, CeDUR, and stone-coated steel for Lake Waconia
Most Waconia contractors stock one shingle line and one siding line. For Lake Waconia lake homes that's not enough. We install CertainTeed, Malarkey, Atlas, LP SmartSide, and James Hardie for standard projects — plus DaVinci Bellaforté Slate, DaVinci Multi-Width Shake, CeDUR Walden cedar shake, and stone-coated steel for the lake corridor. Five-shore Lake Waconia wind exposure asks for Class 4 impact ratings and 110-190 MPH wind ratings.

Owner-led on premium
Joe walks every Waconia premium project
Joe Dvorak personally walks every Waconia install over $40,000 — Lake Waconia lake homes, Coney Island properties, and historic downtown buildings — before our crews start. The Modex shop is in Eden Prairie, roughly twenty miles east of Waconia. Most lake-home and historic-downtown decisions hinge on details a crew lead catches but a salesperson misses: rafter condition under a 1920s slate, original flashing detail at a parapet wall, soffit ventilation on a tight lake-cottage eave.

Lifetime warranty
Lifetime workmanship warranty
Industry standard on roofing workmanship is 5 to 10 years. Modex backs every Waconia residential install for the lifetime of the roof, siding, or window — transferable on premium product lines, which matters at resale in a Carver County market that's rotated buyers steadily for a decade. Our Atlas Pro+ certification plus a complete Signature Select system install is what registers the extended manufacturer warranty — up to 20 years non-prorated, on top of our workmanship coverage.
