Sealing the Structure — Wall Sheathing & Roof Decking
Complete building envelope services including wall sheathing, roof decking, weather-resistive barriers, and exterior cladding. We seal the structure tight so interior trades can work on schedule regardless of weather.
Every capability below is delivered by Trinity crews on the job site — not subcontracted. That means tighter quality control, cleaner schedules, and one accountable team from start to finish.
Structural sheathing installation — plywood, OSB, or gypsum-based products — applied to exterior framing to provide lateral bracing, a nailing surface for cladding, and the first layer of weather protection.
Roof deck installation over trusses or rafters using plywood, OSB, or metal decking. Proper fastening patterns and edge detailing ensure the roof system performs as engineered under wind uplift loads.
House wrap, fluid-applied membranes, and self-adhering barriers that prevent bulk water intrusion while allowing moisture vapor to escape. Critical for long-term wall assembly performance in Texas heat and humidity.
Sealing penetrations, transitions, and joints at windows, doors, and wall-to-roof connections. A continuous air barrier reduces energy costs and prevents moisture-related issues inside the wall cavity.
Six things you get with Trinity that you won't get from a broker who subs the work out and disappears until the next invoice.
Every project follows the same disciplined sequence — so estimates hold, schedules stick, and quality stays consistent from the first site walk to final walkthrough.

The building envelope is the physical barrier between the interior and exterior of a structure — walls, roof, foundation, windows, and doors. Our scope focuses on the sheathing, decking, and weather barrier layers that make the building weather-tight before interior work begins.
A properly installed building envelope prevents water intrusion, controls air leakage, and contributes to the structural integrity of the building. Failures in the envelope are the leading cause of premature building deterioration and mold issues.
Yes. We install envelope systems on single-family homes, townhomes, multi-family housing, and commercial buildings. The materials and methods vary by application, but the goal is always the same — a tight, durable building shell.
