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

Aluminum is non-ferrous—it contains no iron, so it cannot rust chemically. Instead, it forms a self-healing aluminum oxide layer that protects the metal underneath. When scratched, this layer reforms naturally. Andrews South receives about 626 mm of annual rainfall and gusts up to 98 km/h, which stress steel roofs and trigger rust cycles; aluminum's corrosion resistance means your roof remains structurally sound through those moisture and wind events year after year.

Yes. Interlock panels use four-way interlocking technology and are warranted to resist winds up to 120 mph when installed to specification. Andrews South experiences typical gusts around 98 km/h, so your roof will handle the strongest seasonal conditions with a safety margin. The interlocking design also prevents panel uplift during pressure spikes, which is critical in your region's wind climate.

No structural reinforcement is needed. The Tile profile weighs approximately 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—while the Shingle profile is even lighter at 0.41 lb/sq ft. This light weight allows installation directly over most existing roofs. Andrews South's average of 3 freeze-thaw days per year can stress heavier materials; aluminum's minimal load protects your home's framing from that seasonal stress.

energy-efficient colors reflect rather than absorb solar heat, reaching initial solar reflectance up to 0.55 and thermal emissivity of 0.84. Andrews South averages about 3,564 sunshine hours annually—more than most U.S. cities—so this reflectivity translates directly into reduced air-conditioning demand. Metal roofs shift the cooling burden compared to asphalt, which absorbs that same high solar load.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rust, rot, splitting, cracking, curling, and impact-resistance loss. It transfers once to the next owner with a 50-year term from completion. This one-time transferability strengthens resale appeal. Given Andrews South's 3 freeze-thaw cycles annually and 98 km/h gusts, having a non-prorated lifetime warranty against weather-related failures—not pro-rated percentages—is substantial protection.

Yes. Aluminum is non-combustible and achieves Class A fire classification, the highest available. This meets or exceeds fire codes in Texas under ICC-ES evaluation report ESR-1790 (IBC/IRC, reissued 2025). Andrews South's annual sunshine of 3,564 hours and low winter precipitation mean dry conditions prevail; Class A rating provides peace of mind during those fire-season months when wind gusts and dry vegetation increase wildfire risk.

Five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each is manufactured in four-way interlocking aluminum panels with the Alunar 70% PVDF fluorocarbon finish on both sides. The coating is warranted 30 years against chalking and fading, so colors remain stable through Andrews South's 3,564 annual sunshine hours. All profiles install with the same lightweight, durable technology and wind/impact protection.

Minimal. Unlike asphalt shingles, metal roofs do not crack, curl, or lose granules. Unlike clay tile, they do not split or rot. The Alunar 70% PVDF coating resists chalking and fading for 30 years, verified to ASTM standards. Andrews South's 626 mm annual rainfall means your roof stays naturally clean; a periodic visual inspection is typically all that's needed to confirm fasteners and flashing remain tight in your moderate-wind climate.

Yes, in most cases. The extraordinary light weight of Interlock panels—as little as 0.41 lb/sq ft for the Shingle profile—allows installation over existing roofs without structural concerns or costly tear-offs. Interlock Roofing of America, serving Andrews South since 2014, can assess your deck and determine whether an overlay or tear-off is best for your home. Installation typically completes faster than asphalt reroof projects.

Aluminum is approximately 95% recyclable at end of life, breaking the asphalt tear-off-to-landfill cycle. Interlock has manufactured panels since 1998 in Delta, BC, and installations range from coastal salt-air homes to an Antarctic research station, demonstrating durability that minimizes replacement waste. Andrews South's 626 mm annual rainfall and 3 freeze-thaw days test material longevity; choosing a roof that lasts a lifetime and recycles, rather than requiring landfill disposal every 15–20 years, reduces your environmental footprint significantly.

Yes. Andrews South averages about 1 cm of snow, 626 mm of rain, roughly 3 freeze–thaw days a year, with peak wind gusts near 98 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.
