Roofing, Siding, and Replacement Windows in St. Charles County

Expert Roofing, Siding and Window Replacement For St. Charles County Homeowners

We Really Are Better Than The Other Exterior Remodeling Companies In St. Charles County. We’ll Prove It.

Welcome to XteriorPRO—the “best or bust” roofing, siding, and window company in St. Charles County.

We do things a little differently than most exterior-remodeling contractors. Instead of offering the typical Good, Better, Best line of products to satisfy a variety of budgets, we offer only the Best in every category.

What Are The Best Roofing, Siding, and Replacement Window Products?

We’re one of the few Master Elite roofers in the area that strongly promotes the Golden Pledge Warranty (GAF’s best warranty).

  • This means we don’t do vinyl or wood siding… we only install James Hardie fiber cement siding.
  • This means we don’t install double pane windows… as Your Local Window Depot USA, it’s triple pane replacement windows ONLY.
  • This means we only use top of the line materials and products when replacing your roof.

How Much Is ‘The Best’ Roofing, Siding, & Windows Going To Cost in St. Charles County?

Does our insistence on best-in-class products mean we’re the cheapest? No—you can definitely find a company willing to install inferior products at a cheaper price.

But we do offer you the most value for your money. Our prices align with what it takes to do the job exactly right. No more. No less.

We don’t nickel-and-dime you or surprise you with hidden charges on the final bill.

The price we quote is concrete. Period.

If you do find a St. Charles County exterior remodeler who quotes you a cheaper price for the same materials and workmanship within 30 days of signing our Price Pledge, we’ll price-match them and give you $100.



It’s Only Top Of The Line Remodeling Products. Every. Single. Time.

We take the same approach to installation that we do for the products we sell. It’s why we hire only the best and most experienced installers—and pay them nearly DOUBLE what many contractors pay their installers. We understand that quality doesn’t come cheap.

We’re more than happy to invest whatever is necessary to ensure the best possible outcome for our customers.
