Chicago Roofing, Siding & Window Replacement

Zags Exteriors has been based in Northbrook for more than 45 years, and we work across the entire Chicago area: the city itself, the North Shore, and the western suburbs out through the Fox Valley. Roof replacement and repair, siding, window replacement, and storm damage restoration, all handled by crews who know how a Chicago winter and a Midwest hailstorm actually treat a building.

Built for Chicago Winters

Chicago winters are hard on a roof. Lake effect snow and the freeze and thaw cycle that follows it put real stress on roof decking and flashing all winter, and poor attic ventilation turns into ice dams along the eaves almost every year somewhere in our service area. Summer brings hail, often severe enough that homeowners don't realize they have damage until an adjuster is already out on the block. We do free storm damage inspections and can walk you through what your policy covers before you file anything.

Local Service Areas

Chicago is a big market, and where you are shapes which crew and timeline makes sense. Two of our most established areas:

North Shore (Northbrook, Winnetka, Wilmette, Glenview, Highland Park, Deerfield, Lake Forest) is where we're headquartered and where our project history runs deepest. See North Shore details

Western suburbs and Fox Valley, including the Oswego area, is where we've taken on some of our largest projects, residential and multi-building community work alike. See western suburbs details

If you're elsewhere in the city or suburbs and don't see your area listed, reach out. We cover a wide radius from Northbrook and can tell you quickly whether your address is in range.

Services Available in the Chicago Area

Here's what we handle across the Chicago area:

Residential roof replacement and repair. Asphalt, metal, cedar shake, slate, and tile roofing for homes across the city and suburbs.
Commercial and multi-family roof replacement and repair. Roofing for larger residential and mixed-use properties.
Siding installation. James Hardie fiber cement and vinyl siding, with shake styles in both, built for Chicago winters.
Window replacement. Full residential service throughout Chicago, plus HOA and condo association scale projects.
Storm and hail damage inspection and insurance claim support. Free inspections and help documenting damage for your adjuster.
Gutters. Seamless gutters sized for heavy snow and rain.

Built to Manufacturer Spec, Backed by Warranty

Every roof and siding job we complete in the Chicago area is installed according to manufacturer guidelines, which is what keeps your product warranty valid if something goes wrong down the road. We'll walk you through exactly what's covered, and for how long, before we start any work.

45+ Years Serving the Chicago Area

Zags Exteriors has been headquartered in Northbrook for more than 45 years, and we've worked across the city and suburbs ever since. We're not a national company that showed up after a big storm, we're the roofing and siding contractor your neighbors already call. Contact us today to schedule a free inspection anywhere in the Chicago area.

Siding and Windows Built for This Climate

We install James Hardie fiber cement and vinyl siding, including shake styles like HardieShingle and vinyl shake, and Illinois is where we've done the most of it. Materials here have to handle humidity swings and freeze and thaw cycles every year without failing at the seams, and that's a different demand than a milder climate puts on the same product.

Window replacement is a full residential service throughout Chicago and the surrounding suburbs, not just something we offer for larger projects. We also handle window replacement at HOA and condo association scale, the same kind of multi-building work we've done for communities in the western suburbs.

Get a Free Inspection Anywhere in the Chicago Area

Whether you're dealing with storm damage, planning a siding or window upgrade, or just want a second opinion before a big repair, we'll come out, take a look, and give you a straight answer. No pressure, no upsell. Contact us to schedule your free inspection anywhere in the Chicago area.

Does Zags work in the city of Chicago, or just the suburbs?

Both. We’re headquartered in Northbrook, so the North Shore and the western suburbs are where we have the longest track record, but we take on roofing, siding, and window projects throughout the city as well. Tell us your address and we’ll confirm the timeline for your location.

What's the difference between your North Shore and western suburbs service?

Mostly project history and scale. The North Shore is our original market and skews toward single family homes. The western suburbs, including the Fox Valley and Oswego area, is where we’ve also taken on large multi-building community projects alongside residential work. Both areas get the same crews and materials.

Do you handle HOA and condo association projects in the Chicago area?

Yes. We’ve completed large scale roofing, siding, and window replacement projects for condo and homeowners associations in the western suburbs, including work spanning dozens of buildings and hundreds of units. We can’t share client names or addresses, but we’re glad to walk a board through our project history and references.

How fast can you get to a storm damaged roof in the Chicago area?

After a significant hail or wind event we prioritize emergency tarping and inspections first, then move into scheduled repairs and replacements. Call us and we’ll give you a real timeline based on current demand and your location.
