Earlier this month, United Airlines had a major event scheduled at IAH. Just two days before the event, multiple roof leaks suddenly appeared directly over the event space.

They called us on a Monday.

We responded immediately.

Our team mobilized fast, assessed the situation, built a plan, and assembled the largest crew necessary to resolve the issues well before guests ever arrived.

Shortly after, we received an unsolicited testimonial from United Airlines’ facilities team — and hearing it shared again in our morning meeting was a powerful reminder of why we do what we do.

This is what partnership looks like:
✔️ Responsiveness when it matters most
✔️ Clear communication under pressure
✔️ Experience you can trust in critical moments

Thank you to United Airlines for trusting R.B. Hash Roofing + Waterproofing — and to our field teams who show up every single time.

When the stakes are high, experience and urgency matter.
