St. Louis Roofing, Siding & Storm Damage Repair

Zags Exteriors serves homeowners and businesses throughout the St. Louis metro, including Clayton, Kirkwood, Webster Groves, Chesterfield, Ladue, and Town and Country, with roof replacement and repair, siding, and storm damage restoration.

Why St. Louis Roofs Take a Different Kind of Beating

Missouri sits in one of the most hail prone parts of the country, and St. Louis gets more than its share of severe spring and summer storms. A roof here can go from good condition to needing a full claim in the space of one afternoon storm. We do free hail and wind damage inspections, and because we see this constantly in this market, we know what an adjuster is going to look for before they show up.

St. Louis also has a lot of older housing stock, brick homes with roof lines and flashing details that a lot of national roofing companies aren't set up to handle correctly. We work with those roofs regularly, not as the exception.

One Team for Every Job on Your Home

Most homeowners end up juggling separate contractors for the roof, the siding, and the windows. We handle all three in house, so you're working with one crew and one point of contact from the first inspection to the final walkthrough.

Services Available in St. Louis

Here's what we handle for St. Louis homeowners:

  • Residential roof replacement and repair. Asphalt, metal, cedar shake, slate, and tile roofing built to hold up to severe hail seasons.
  • Siding installation. James Hardie fiber cement and vinyl, with shake styles in both.
  • Window replacement. For HOA and condo association communities (large-scale projects; not yet a standalone homeowner service in this market).
  • Storm and hail damage inspection and insurance claim support. Free inspections and help documenting damage for your adjuster.
  • Gutters. Seamless gutters built for heavy storms.

Built to Manufacturer Spec, Backed by Warranty

Every St. Louis roof and siding job 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.

Siding for St. Louis Homes

Between hail impact and Missouri's humidity swings, siding here needs to hold up to more than looks. We install James Hardie fiber cement and vinyl siding, including shake styles like HardieShingle and vinyl shake. Both are built to handle the freeze, thaw, and storm cycle this region goes through every year.

How long do I have to file a hail damage claim in Missouri?

Timelines vary by insurance carrier and policy, typically somewhere between one and three years from the date of loss, but the specifics are in your policy, not a general rule. We can help you find that language and walk through your options before you file.

It can. Unaddressed hail damage tends to worsen (leaks, granule loss, shortened shingle life), and some carriers will flag it at renewal or during a future claim. Getting an inspection after a storm, even a minor looking one, protects you either way.

We won’t file the claim for you since that’s between you and your carrier, but we’ll document the damage thoroughly, meet the adjuster on site, and make sure the estimate reflects what your roof actually needs.

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.
