McElroy Metal 1.5" Sure Lock Standing Seam Roof Installation | Full Re-Deck With High-Temp Underlayment for Central Texas Heat









This North Austin home received a full metal roof replacement through an insurance claim. We used McElroy Metal's 1.5" Sure Lock snap-lock standing seam profile in 24-gauge steel, set on a roughly 16.5" pan. The concealed-clip design lets the panels expand and move as temperatures swing past 100 degrees each summer. Standing seam metal handles Austin hail and heat far better than the aging shingles it replaced, so the homeowner gets decades of protection.

This project started with a door-knocking conversation in North Austin, logged as a lead on July 21, 2023. The homeowner had a shingle roof showing storm wear and wanted to understand their options.
We inspected the roof and confirmed hail damage across the shingle sections. Our assessment showed the decking itself was aging, so a metal replacement backed by an insurance claim made the most sense for the long term.
The job moved to prospect status on November 17, 2025 as we worked through the details. The insurance claim was approved May 7, 2026, and the homeowner selected McElroy Metal's 1.5" Sure Lock standing seam in 24-gauge steel with color-matched trim.
Crews mobilized on June 10, 2026 with coil stock and trim staged on site. We tore off the old shingles, installed new 7/16" OSB decking and Epilay Ultra high-temp underlayment, then snapped the standing seam panels and tied in all flashing. The full install ran two days.
We finished the roof, set the vented ridge cap, and cleared all offcuts and fasteners from the property.
We tore off a hail-battered shingle roof in North Austin and installed a McElroy Metal 1.5" Sure Lock standing seam system in 24-gauge steel. The result: a tight, storm-ready roof finished in two working days on job APS-4814.
The old shingle roof took hail damage, and the insurance carrier approved a full replacement. Once shingles bruise, the granules loosen and the roof starts shedding protection fast under the sun.
Once we stripped the shingles, the decking told the real story. Years of Central Texas heat and moisture cycles had left the substrate needing a full refresh, so we replaced it with new 7/16" 4'x8' OSB panels rather than laying metal over questionable wood. This matters more than most homeowners realize. A standing seam roof is only as flat and true as the deck beneath it, and any soft spot or dip shows up as an oil-canning wave once the metal goes on. Starting with solid decking is what keeps the finished panels looking crisp for the long haul.
We built this roof around McElroy's 1.5" Sure Lock snap-lock profile because the concealed-clip system handles heat movement without exposed screws. When your roof deck bakes past 100 degrees, the steel panels need room to expand and contract. The clips let each panel float, so nothing binds, buckles, or backs a fastener out over time. That single detail is why standing seam outlasts screw-down metal in our climate.
Underneath the panels, we rolled out Epilay Ultra high-temp underlayment, which is rated to survive the heat trapped under metal on a July afternoon. Standard felt would cook and crumble in that environment.
Our crew ran the job over two full days, start to finish on June 10, 2026. Tear-off, re-deck, underlayment, and panel install all moved in sequence so no open decking sat overnight.
The home now wears a full standing seam metal roof that reflects heat, sheds hail, and won't need re-shingling in a decade. Cedar pollen and debris rinse off a smooth metal surface far easier than off a granular shingle roof.
Metal stands up to hail impact and reflects the summer sun, so your attic runs cooler. Unlike shingles, it won't lose granules or curl under repeated 100-degree days, which stretches its useful life well past a typical asphalt roof.
Two full working days, wrapped up on June 10, 2026. That included tearing off the old shingles, laying new decking, and installing every panel and trim piece.
This project fell in the $25,000 to $30,000 range and ran through the homeowner's insurance as an approved hail claim. Every roof is priced by size, pitch, and material, so figures vary home to home.
Yes. The vented Z-bar we installed lets hot air escape the attic, which eases the heat load on your home and helps the whole roof assembly last longer through Austin summers.
