Metal Roofing in Selma, Texas — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum cannot rust because it contains no iron — the element that oxidizes and corrodes. When aluminum is scratched, its oxide layer self-heals automatically. This matters in Selma because your area sees about 1046 mm of rain annually plus wind gusts to 103 km/h that can carry moisture into crevices. Steel roofs require paint maintenance and eventually fail; Interlock's 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) stays structurally sound indefinitely. The Alunar 70% PVDF fluorocarbon finish on both sides adds another 30-year warranty against chalking and fading, giving you two layers of corrosion defense.

Interlock panels carry a UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. That's meaningful for Selma, where spring storms bring hard rain and occasional severe weather. The four-way interlocking aluminum design absorbs impact without cracking or splitting like asphalt or wood shakes do. Many insurers recognize Class 4 ratings and offer premium discounts. You'll want to share your roof's rating with your agent; it's one of the few upgrades that can actually lower your yearly costs instead of just protecting you.

Yes—Interlock's energy-efficient colors reflect solar heat instead of absorbing it the way asphalt does. Selma gets about 3354 sunshine hours per year, so that reflection adds up fast. Cool Roof Rating Council certified finishes achieve thermal emissivity of 0.84 and initial solar reflectance up to 0.55 in Aged Copper Penny, which means less heat penetration into your attic during Texas summers. Lower attic temperatures mean your AC works less and your cooling bills drop. Over 50 years, that energy saving often exceeds the roof's installed cost, especially in a sunny climate like yours where the roof faces 20 or more peak-sun days most months.

The Guardian warranty is lifetime limited and non-prorated for the original owner — it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance for as long as you own the home. It's also transferable once, giving the next owner an additional 50 years from completion. In Selma's climate with about 7 freeze-thaw days per year, asphalt shingles start failing after 15–20 years; Interlock roofs installed since 1998 in environments from coastal salt air to Antarctic research stations are still performing. One lifetime warranty means this is the last roof you'll buy, and your roof's value carries forward if you sell.

Yes—Interlock's aluminum is extraordinarily light. The Slate profile installs at about 0.41 lb/sq ft, the Shake at 0.58, and the Mediterranean Tile at 0.59 lb/sq ft. That tile profile is roughly 96% lighter than concrete or clay tile, so no structural reinforcement is needed. Most homes can handle it over existing roofing. Compare that to the structural work and framing upgrades required by heavy tile; you avoid that cost and disruption entirely. Interlock received ICC-ES evaluation report ESR-1790 (reissued 2025) confirming compliance with IBC and IRC code requirements for residential installation, including over existing roofs in areas like Selma with moderate rain (about 1046 mm annually) and gusts to 103 km/h.

Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec — well above Selma's typical wind gust maximum of about 103 km/h. The four-way interlocking design locks each panel to its neighbors, distributing wind load across the entire roof rather than relying on fasteners alone. That's why the design works from coastal salt-air homes to extreme-weather sites. Your area's average daily-max winds of about 18 km/h are routine for metal roofing; even spring storms and the occasional strong gust won't move a properly installed Interlock roof. The locking system also prevents the flutter and rattle you sometimes hear with other metal roofs.

Interlock requires virtually no maintenance — no annual inspections, no sealing, no coating renewal. The roof cleans itself with rain (Selma averages about 1046 mm yearly). Asphalt shingles need inspection every year for curling, algae, and granule loss, especially after the area's occasional freeze-thaw cycles (about 7 per year). Wood shakes split and rot and demand treatment. Concrete and clay tile crack and leak around fasteners and mortar joints. Aluminum doesn't splinter, rot, chalk without a 30-year warranty, or need re-sealing. CALGreen-verified for reduced maintenance means Selma homeowners filing for certain energy rebates or sustainable-building credits can use this roof to qualify.

Interlock manufactures five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each locks together four-way and is made from roofing-grade 3105-H24 aluminum with Alunar 70% PVDF coating. The Slate and Cedar Shingle profiles appeal to homeowners wanting traditional aesthetics; the Shake and Tile profiles suit Mediterranean or Spanish Colonial homes common in south-central Texas. Standing Seam is contemporary. All five profiles deliver the same durability, lightweight installation, and lifetime warranty. Your choice comes down to architectural style and whether you want a textured profile or clean lines. Interlock Roofing of America, serving the region since 2014, can show you samples and discuss which fits your home's design.

Upfront cost is higher — typically 2–3 times asphalt. But lifetime cost favors metal decisively. Asphalt fails in 15–20 years in Selma's climate (1046 mm rain, 7 freeze-thaw days annually) and goes to landfill; you then buy and install a second roof. Interlock roofs last indefinitely under the Guardian lifetime warranty, transferable once for 50 years to the next owner. Factor in zero maintenance, no tear-off costs, and energy savings from energy-efficiency reflectance, and the per-year cost drops below asphalt by year 25–30. You also avoid the labor and disruption of a roof replacement mid-ownership. This is the last roof you buy — that certainty has value beyond the spreadsheet.

Aluminum is non-combustible — it cannot catch fire. Interlock offers Class A fire classification (the highest available) because aluminum will not ignite or spread flame. That rating comes from ICC-ES evaluation ESR-1790, which confirms compliance with IBC and IRC fire codes. Asphalt shingles are Class C or B and can ignite from embers during brush or wildfire events. Wood shakes are even more vulnerable. In south-central Texas, wildfire risk varies by location, but a non-combustible roof eliminates one variable entirely and often qualifies you for homeowners insurance discounts. Your insurance agent can confirm premium reductions available for Class A roofing in Guadalupe County.

Yes. Selma averages about 2 cm of snow, 1046 mm of rain, roughly 7 freeze–thaw days a year, with peak wind gusts near 103 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
