High-End Roofing, Siding & Windows In West County…
And The Superior Installation They Demand

GAF Golden Pledge Roofing, James Hardie Fiber Cement Siding
& Window Depot USA Triple Pane Windows.

Looking for the most premium-quality roofing, siding, and windows in West County? If so, you’ve landed on the right website.

At XteriorPRO (also Your Local Window Depot USA), we do things a little differently. Instead of offering different levels of products at different price points, we offer only high-end products.

  • That means we don’t install double pane windows—it’s triple pane only.
  • That means you won’t find us putting vinyl siding on a customer’s home—we install James Hardie fiber cement siding exclusively.
  • That means we are one of the few Master Elite roofers in the area who strongly recommend the Golden Pledge Warranty—GAF’s strongest guarantee..

Why do we take a “best or bust” approach to roofing, siding, and windows in West County? It’s simple—we’re a Zero Compromises company. We have a strict policy to never, ever cut corners on anything… period. It doesn’t matter if it takes a little longer. It doesn’t matter if it costs us a little more. We do what’s necessary to ensure the highest quality outcome.

Our Zero Compromises policy extends to our installers as well. We pay our installation crews almost double the going rate than what many exterior-remodeling companies pay in West County. This is how we acquire and keep the top installation talent in the area. Explore our Master Elite Roof Installation, Siding Installation, and Window Installation for details on how we leave no stone unturned with our workmanship.

While we have stringent installation policies, our approach to in-home consultations is summed up in one word: relaxed.

We don’t twist your arm. We don’t play pricing games. We don’t try to force you into a decision before you’re ready. We actually listen to you, make our expert recommendation, and provide you with honest solutions. We then provide you with a firm and fair quote for our services.

If you choose us, great! If you decide to go in another direction, that’s okay, too. We want what’s best for you, but we also want you to feel 100% comfortable about your decision.

Our customers love our approach to exterior remodeling. Take a look at our reviews, peruse our awards, and contact our references. You’ll see we’re the right company for high-quality roofing, siding, and windows in West County.
