Lake-corridor premium

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.

Questions

Waconia homeowners ask about Lake Waconia lakefront scopes, historic-downtown slate preservation, Carver County permits, ISD 110 subdivisions, and the 2020-2026 storm history.

Yes — Lake Waconia lakefront is a meaningful share of our Waconia project mix. Lake Waconia is the tenth-largest lake in Minnesota by surface area (around 3,080 acres), and the homes on the south, east, and west shores trend toward 35 to 60 squares of roof. Lakefront properties typically need DaVinci Bellaforté Slate, DaVinci Multi-Width Shake, or CeDUR Walden cedar shake to clear neighborhood expectations and stand up to wind exposure off the open water. We pull a Carver County shoreland-overlay setback packet before ordering materials on any Lake Waconia install.

City of Waconia building permits are filed through the City Hall office at 201 South Vine Street, Waconia MN 55387, (952) 442-2184. The city is the issuing authority inside Waconia limits; Carver County handles the shoreland-overlay layer on Lake Waconia properties and the unincorporated townships north and west of the city. We pull every Waconia permit before our crews start work, schedule the required mid-tear-off and final inspections, and include the permit fee in the line-item quote. Most Waconia residential permits clear in 5 to 10 business days.

Sometimes yes, sometimes the structure is past the point of preservation — we tell you the honest answer after we walk it. Original 1860s-1880s slate on the historic downtown Waconia commercial block can run 100+ more years if the slate itself is sound and only the flashings, ridge caps, and underlayment have failed. We do selective slate replacement with matched-quarry slate (Vermont or Pennsylvania), rebuild copper flashings, and re-set ridge caps. If the slate field is fractured beyond reuse, DaVinci Bellaforté Slate or natural slate from a current quarry are the two paths forward. Joe walks every historic-downtown Waconia project before crews start.

Waconia sits in the south-central Twin Cities storm corridor. The June 2023 hail cycle dropped 1.5-inch to 2-inch hail across the city and the south shore of Lake Waconia. August 2023 brought a second hail event that hit the ISD 110 subdivisions on the west side hard. June 2024 saw straight-line wind damage along Highway 5 and the lake's east shoreline. We worked dozens of insurance roofs in Waconia across the 2023-2024 cycle. We pull MRMS hail-swath data for your specific address before we set the ladder on any insurance inspection.

Yes — the 1990s-2010s subdivisions inside Waconia Independent School District 110 are the bulk of our standard-asphalt and engineered-wood-siding project mix. Most ISD 110 homes are first or second roof-replacement age, with CertainTeed Landmark Pro, Malarkey Vista AR, and Atlas Pinnacle Pristine being the three lines we install most often on these properties. James Hardie ColorPlus and LP SmartSide ExpertFinish are the two siding lines that clear the typical Waconia HOA aesthetic at different price points. Class 4 impact-resistant upgrades qualify for 10 to 30 percent homeowner insurance discounts in Carver County.

Very well, and the Lake Waconia exposure is exactly why we install it there. DaVinci Bellaforté Slate carries a Class 4 impact rating, a 110 MPH wind rating (up to 190 MPH with enhanced fastening), and a Class A fire rating. The product is engineered for the wind exposure that comes with sitting on the open water of a 3,080-acre lake. Color stability runs decades — UV-resistant pigments, no curling, no granule loss like asphalt sheds in year fifteen. At our 2026 installed rates of $2,500 to $3,500 per square, a 45-square Lake Waconia roof lands $112,500 to $157,500 lump-sum with copper valleys and a properly engineered ridge-vent system.

We do. The 1990s–2010s ISD 110 subdivisions make up most of our Waconia siding work — much of that builder-grade vinyl is now faded, cracked, or hail-dented from the 2023–2024 storm cycle. We install LP SmartSide engineered wood ($22,000–$50,000 on a typical Waconia home) and James Hardie fiber cement ($30,000–$80,000) — both clear the typical Waconia HOA aesthetic, hold color for decades, and handle Carver County freeze-thaw far better than the original vinyl. We carry vinyl on request, but for most Waconia homes we lead with LP or Hardie and tell you the tradeoffs honestly.

Yes. The ISD 110 subdivisions are largely still running their original 1990s–2000s builder double-pane windows, and at 25-plus years most have lost their seal — foggy glass, drafts, and high winter bills. We install ProVia, Kolbe, and Pella, from value vinyl ($1,400–$2,500/window) up to architectural lines for Lake Waconia lake homes ($2,500–$6,000/window). We'll spec the right line for the home, not the brand with the deepest kickback.
