Roofing, Done Right

Your home’s exterior has one job: protect the people inside.

OUR MISSION

Castrum is Latin for castle. We chose the name as a reminder of what the work is really for. A roof isn't just shingles and flashing. It's what stands between your family and a Gulf Coast storm.

Our goal is to be the exterior company Houston families call first and recommend to their neighbors, because we earned it. Here's how we work:

Honest Advice

We recommend what your home actually needs, even when that's a simple repair.

Earned, Not Assumed

You don't pay until the job is done and you're satisfied with it.

Work That Lasts

Certified installers and premium materials, built for Texas heat and hurricane season.

Here For The Long Haul

We're locally owned. We answer the phone, and we'll be here next storm season.

  • Fair pricing matters. While there will always be someone willing to do the job for less, the lowest price does not always mean the best value.

    Castrum Exteriors & Construction stays current on industry pricing and insurance repair standards to help ensure estimates are fair, competitive, and appropriate for the work required. Insurance claims are generally intended to support repairs completed by qualified contractors who can manage the project responsibly, communicate clearly, pay suppliers and crews properly, and stand behind their work.

    Our goal is simple: provide professional service, quality workmanship, and responsible pricing from start to finish.

  • No. In most cases, we do not require a down payment to begin work, whether your project is paid through insurance, financing, or directly by you.

    Payment timing may vary depending on the type of project and your contract terms, but our goal is to make getting started as straightforward as possible.

  • Choosing the right contractor is about more than comparing prices. Look for a company with a strong reputation, proper insurance, clear communication, quality workmanship, and a willingness to stand behind its work.

    Take time to review references, ask questions, and make sure you understand exactly what is included in the proposal. The best choice is a contractor you feel confident will communicate honestly, complete the work professionally, and be there if you need them after the project is finished.
