Lake-corridor premium
Chanhassen's lake neighborhoods — Lake Minnewashta, Lake Susan, Lotus Lake — trend toward premium materials when original asphalt reaches end of life. CertainTeed Presidential Shake TL, DaVinci synthetic slate (we install, not Authorized), James Hardie ColorPlus, and Kolbe Heritage windows are typical of the lake-corridor mix. Joe walks every Chanhassen install over $40,000 before crews start.

Chanhassen housing stock
Most of our Chanhassen project mix is 1980s and 90s suburban buildout — South Lotus Lake ramblers, Lotus Lake Estates split-levels, Colonial Grove traditionals, and Longacres. Lake-corridor customs around Lake Minnewashta add premium-material projects to the mix.

1980s + 90s buildout
South Lotus Lake (35 single-family), Lotus Lake Estates (ramblers/ranches/splits), Colonial Grove (70 homes east of Lotus Lake), and Longacres (245 traditional + rambler homes on the northwest side). Most at first or second roof-replacement age. Ridge vent retrofits common — these homes were built with marginal attic ventilation that's now driving ice dam frequency.

Lake-corridor customs
Lake-corridor customs trend toward premium materials — CertainTeed Presidential Shake TL, DaVinci synthetic slate (we install, not Authorized), James Hardie ColorPlus, Kolbe Heritage windows — when the original asphalt reaches end of life. Joe personally walks every Chanhassen install over $40,000.

Why Chanhassen
Three things separate us in the Chanhassen market: five shingle lines instead of one, owner Joe Dvorak personally walks every project over $40,000, and every residential install carries a lifetime workmanship warranty.

Five certifications
Most Chanhassen contractors stock one shingle line and one siding line. We install CertainTeed, Malarkey, Atlas, LP SmartSide, and James Hardie — so the homeowner picks the material that fits the home and the budget, not whatever the contractor's supplier has on the truck. For lake-corridor customs we also install DaVinci synthetic slate and standing seam metal.

Owner-led
Joe Dvorak personally walks every Chanhassen install over $40,000 before our crews start. On Lake Minnewashta and Lotus Lake customs, that's most of the project mix. Joe leaves from the Modex shop on Rosemary Road in Eden Prairie — five miles east. Most Chanhassen properties are 15–20 minutes from the shop.

Lifetime warranty
Industry standard on roofing workmanship is 5 to 10 years. Modex backs every Chanhassen residential install for the lifetime of the roof, siding, or window. The Atlas Pro+ Silver Select certification enables a Signature Select extended manufacturer warranty up to 20 years non-prorated on top of our workmanship coverage.
