“I had a great experience with OSAAT Roofing and Construction. Richie and his team came out to work on my roof and exceeded expectations in every way. The team was professional, arrived on time, and quickly assessed the issue with accuracy and confidence. What really stood out was how affordable their service was compared to others, without sacrificing quality. They worked with my insurance and handled all the details I couldn't understand, which made the whole process so much easier. He was incredibly kind and patient, taking the time to explain everything clearly.”

MEET THE OWNERS
OWNER-LED. LOCAL. CENTRAL TEXAS.

Christopher Navas and Richard Seymour started OSAAT in 2025 after years inside a roofing industry they felt had stopped treating homeowners fairly. Chris came up through the manufacturing and install side of metal and shingle roofing. Richard came up through retail, commercial, and insurance work across several states, with his focus on Central Texas.
Two owners run every job, start to finish. We inspect the whole roof, document it with photos and video, meet your insurance adjuster on-site, and tell you the truth even when it is not what you hoped to hear. That is the whole business, one step at a time.
OUR VISION
To be the contractor Central Texas homeowners recommend by name when their neighbor needs a roof.
OUR MISSION
Honest inspections. Documented work. Local, insured crews. Warranties that mean something.

How to Fix Attic Ventilation Problems in Killeen: A Guide for Homeowners
If you're trying to figure out how to fix attic ventilation problems in Killeen, the short answer is this: add or unblock intake vents at the roof's edge and exhaust vents at the ridge so hot air can actually escape.
