Janesville, WI’s Choice for New Roofing, Siding, and Windows

You might have started noticing that the outside of your home needs some work. Maybe a few shingles are curling, or the siding is fading. Well, good news for Janesville, Wisconsin, homeowners: Heins Contracting has the expertise to get your home’s exterior into its best shape.

From windows and doors to roofs, gutters, and siding, Heins Contracting delivers exterior upgrades and repairs to homeowners across Rock County. We’re a local, family-owned roofing contractor with highly trained craftsmen and excellent quality control. We provide transparent pricing and no-pressure estimates, so you can make decisions based on your home's actual needs.

Roof Replacement and Repair Serving Janesville

Your roof endures more damage than any other home exterior component. Rock County's harsh weather and temperature swings can accelerate wear and tear. Heins Contracting’s roofing services cover everything from repairs to replacements. Many roof replacements are typically completed in a day, depending on the scope.

Heins Contracting holds GAF Master LEED certification and the GAF 2-Star President's Club designation, meaning our work meets superior standards and comes with a strong warranty.

When hail or wind causes damage, our storm damage roofing services guide you through assessment and insurance claims without high-pressure tactics. We also handle ice dam removal for the freeze-thaw cycles common across the Rock County area each winter.

Asphalt Shingle Roofing

GAF asphalt shingles are our primary recommendation for Janesville homes. They suit Wisconsin's seasonal extremes and come backed by manufacturer warranties. Plus, they’re budget-friendly without cutting corners. Heins Contracting covers all asphalt installations with a 10-Year Workmanship Warranty, in addition to the manufacturer’s product warranty.

Additional Roofing Options

Certain homes may need something other than asphalt shingles. For projects requiring alternatives to standard asphalt, we install natural slate from North Country Slate and composite tile from Brava. If asphalt isn't right for your home remodeling goals, we'll let you know.

Siding Installation for Janesville and Rock County Homes

Heins Contracting holds both James Hardie Preferred Contractor and LP SmartSide Master Certified credentials, positioning us among the region's elite siding installers. These credentials helped us earn back-to-back People's Choice Awards in 2024 and 2025.

James Hardie fiber cement siding resists moisture and requires less maintenance than wood or lower-grade materials. LP SmartSide is a strong engineered wood option that works well in our Midwest climate. We offer both products as part of our siding installation services.

Window Replacement in Janesville

Window replacement pricing can vary widely depending on the contractor's quality and the materials used. As a certified Andersen Windows and Doors installer, Heins Contracting expertly installs a full scope of fiberglass, aluminum-clad wood-frame, composite, and wood replacement window options.

For homeowners focused on vinyl windows, Polaris Windows and Doors offers high-quality vinyl products at fair prices, without the typical franchise markups. Our window replacement services include Energy Star-qualifying products that can potentially help offset project costs through tax credits.

Gutter Replacement for Janesville Properties

It’s a smart idea to upgrade your gutters during a roofing or siding project. Undersized or failing gutters can cause major problems with your home if they’re not displacing rainwater quickly and thoroughly enough. We install Champion Gutter Guards as exterior complements that help keep your gutters clean.
