Protection or Beauty? Why not both? At R. B. Hash, we refuse to choose.

This shot of the stunning restoration shows the installation of precision custom sheet metalwork on the exterior of a historic hotel. The work took place on the 12th story, where metal cornice around the edge of the roof that had been ripped off during a hurricane. Scaffolding was erected cantilevered out the windows so we could install the new metal cornice we custom fabricated to match the existing details.

In preservation projects like this, every detail must be historically accurate and functionally superior. Our skilled craftsmen blend architectural detail with high-performance waterproofing, ensuring the perfect balance of aesthetic appeal and durable protection for iconic landmarks.

Out with the old, in with the watertight. 🛠️

When a high-rise plaza deck or roof terrace begins to fail, you can't just slap a patch on it. You have to get to the root of the problem.

Our crew stripped away damaged, water-logged insulation boards layer by layer to prepare the concrete substrate for a high-performance, modern roofing and waterproofing assembly. It’s heavy, methodical work, but it’s the only way to guarantee a luxury property stays protected for decades to come.

When the summer sun hits the Houston Ship Channel, roof temperatures can easily soar past 150°F. Protecting our crew and your facility from the heat is a science. ☀️🌡️

At this industrial installation, the R. B. Hash team was hard at work laying down a durable, energy-efficient commercial roofing system.

Beat the heat breakdown:
🛠️ For the building: The white single-ply membrane acts as a solar shield, reflecting UV rays away from the facility.
👷‍♂️ For the team: Specialized PPE, mandatory hydration loops, and extensive heat-illness training ensure our crews execute complex installations safely and without delays, even in the toughest conditions.

Don't let your roof bake this summer. Let's talk energy efficiency and structural protection.
