24-Gauge Galvalume Standing Seam Metal Roof Installation | Vented Ridge Snap Lock System With High-Temp Underlayment









This Burnet metal roofing project used a 24-gauge Galvalume standing seam roof with a 1.5-inch snap lock panel. We paired the panels with hidden clips, high-temp Epilay underlayment, and a vented Z ridge for airflow. Standing seam holds up far better than shingles against Central Texas hail and 100-degree summers. The homeowner ended up with a sealed, vented, insurance-backed roof finished in one day.

Our salesman met the homeowner while canvassing the Lakevista area of Burnet on May 8, 2025. A recent storm had left roof damage worth filing an insurance claim, and that first-contact conversation turned the lead into a prospect the same day.
We inspected the existing roof and confirmed storm damage that supported an insurance claim. The assessment pointed to a full replacement rather than a patch, given how hard Central Texas hail is on asphalt shingles.
The homeowner selected a 24-gauge Galvalume standing seam system with a 1.5-inch snap lock profile. Working through the insurance claim, the project was approved on May 22, 2025, with McElroy Metal Sure Lock panels specified for the job.
On September 30, 2025, the crew led by Jose Rangel completed the full tear-off and metal install in a single day. They laid Epilay Ultra high-temp underlayment, set eave and rake drip edge, installed the clip-fastened panels, and finished with a vented Z ridge and Galvalume ridge cap. ABC Supply delivered the metal and G&J Seamless Rain Gutters handled the drainage tie-in.
We walked the finished roof the same day, confirming sealed seams and a fully vented ridge. The job was invoiced on September 30 and closed on October 2, 2025, leaving the homeowner with an insurance-backed, low-maintenance metal roof.
We tore off and replaced a storm-damaged roof in Burnet, TX with a 24-gauge Galvalume standing seam metal system, finishing the full job in a single day on September 30, 2025. The home now carries a clip-fastened, fully vented roof built for Hill Country weather.
A storm rolled through and left enough damage to open an insurance claim. Our salesman first met the homeowner while canvassing the Lakevista area on May 8, 2025.
That single visit turned into a full roof replacement. Here's what drove the decision:
We went with a 24-gauge Galvalume standing seam system for its strength and clean look. Galvalume is a steel coated with aluminum and zinc, and that blend fights corrosion far longer than plain galvanized steel.
The real advantage here is the standing seam profile itself. The 1.5-inch snap lock panels lock together over hidden clips, so there are no screws punched through the face of the roof. Those exposed fasteners are usually the first thing to fail on cheaper metal roofs, because the rubber washers dry out and leak under Hill Country heat. By hiding the clips instead, the panels can expand and shift as the roof heats past 100 degrees without tearing at the fastener. Fewer holes in the field means fewer places for water to ever find its way in.
A metal roof is only as good as what sits under it, so we laid a high-temp synthetic underlayment across the deck. We also built a vented ridge to let hot attic air escape.
Good airflow matters more here than most homeowners think. Under a metal roof in a Burnet summer, trapped attic heat cooks a home from the top down and drives up cooling bills. The details we used:
The crew, led by Jose Rangel, completed the tear-off and full metal install in one day. Metal supply came in through ABC Supply, and G&J Seamless Rain Gutters handled the drainage tie-in.
The finished roof is a sealed, vented, corrosion-resistant system that should outlast any shingle roof in the neighborhood. It sheds hail impact, reflects summer heat, and needs almost no upkeep beyond an occasional gutter cleaning after cedar pollen season.
A well-installed 24-gauge Galvalume standing seam roof commonly lasts 40 to 50 years. The hidden-clip design and high-temp underlayment are what carry it through decades of Burnet heat and hail.
Standing seam hides the clips under the panels, so no screws pierce the roof's face. That removes the most common leak point and lets the metal expand freely when temperatures climb past 100 degrees.
This project fell in the $25,000 to $30,000 range and was covered as an insurance claim. Cost varies with roof size, pitch, and how many penetrations need flashing.
From the first canvassing visit on May 8 to approval on May 22, the timeline moved quickly. The actual install was a single day on September 30, 2025.
