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

Aluminum cannot rust because it contains no iron—the metal that corrodes in moisture. Instead, aluminum naturally forms a thin oxide layer that protects it from oxidation, and this layer self-heals if scratched. With Old Union's 1186 mm of annual rainfall and occasional freeze-thaw cycles, this passive protection means your roof won't develop the rust stains or structural decay that plague steel or aging asphalt. The Alunar 70% PVDF coating adds a second defense layer, warranted 30 years against fading, so your roof stays protected as weather cycles repeat year after year.

Interlock's four-way interlocking aluminum panels are warranted to resist sustained winds up to 120 mph, well above the peak gusts your region typically experiences (around 95 km/h). The interlocking design distributes wind load across the entire roof assembly, so panels don't lift or separate when pressure spikes during spring storms. Over Angelina County's 12 freeze-thaw days per year, this mechanical security also prevents thermal expansion and contraction from creating gaps where water might enter. Once installed to spec, your roof stays locked and watertight regardless of seasonal weather swings.

No structural reinforcement is necessary. Interlock's aluminum panels are extraordinarily light—the Mediterranean Tile profile installs at just 0.59 lb/sq ft, making it roughly 96% lighter than traditional tile or slate. This weight advantage matters in Old Union, where older homes and newer builds alike can handle the load without foundation or rafter upgrades. The lightweight design also means you can install over most existing asphalt roofs, avoiding costly tear-off and disposal while keeping installation time short. Your home's existing structure already supports the weight; aluminum simply doesn't demand the heavy framing that ceramic or concrete tile requires.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner—covering rust, rot, splitting, cracking, and impact loss. That means if a manufacturing defect appears in year 25, you're covered at no prorated cost. The warranty is also transferable to the next owner for 50 years from completion, so you're not just buying a roof for yourself but adding documented value your successor can claim. This coverage, paired with aluminum's inability to rust and its 30-year rated coating, reflects what Interlock has learned from installations spanning coastal salt-air homes to Antarctic research stations since 1998.

Yes. Interlock's energy-efficient colors are engineered to reflect solar heat rather than absorb it the way dark asphalt does. The reflectance rating reaches up to 0.55 (Aged Copper Penny), and the thermal emissivity is 0.84, meaning less heat is trapped in your attic during Old Union's 3364 annual sunshine hours. Even in a humid climate with 1186 mm of rainfall, cool-roof colors stay effective because reflectance depends on the coating's optical properties, not rain frequency. Lower attic temperatures mean your air conditioning doesn't work as hard, reducing cooling bills over the roof's life—a direct financial benefit, not just environmental feel-good.

Yes. Interlock aluminum roofing is non-combustible and qualifies for Class A fire classification, the highest rating available. That's because aluminum itself cannot ignite, and the Alunar coating is a synthetic fluorocarbon that does not contribute to flame spread. If wildfire risk or neighborhood fire codes are a concern in Angelina County, Class A certification gives you documented protection and may even lower your homeowners insurance premiums. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms compliance with IBC and IRC fire standards, so your roof meets or exceeds all code requirements.

Minimal. Unlike asphalt shingles that crack and curl, wood shakes that split, or tile that fractures, aluminum doesn't degrade from weather exposure—it has no granules to shed, no fibers to fray, and no seals to dry out. Routine upkeep is limited to annual gutter cleaning and occasional debris removal, especially after Old Union's occasional ice-bearing freeze-thaw days. The Alunar 70% PVDF coating, warranted 30 years against fading, remains intact through salt air, rain cycles, and UV exposure with no refinishing needed. CALGreen verification confirms the system's reduced-maintenance profile, which means more money stays in your pocket instead of going to contractor visits.

Interlock panels overlap and interlock mechanically, creating a tight seal that sheds heavy rainfall before water ever reaches the deck below. With Old Union receiving about 1186 mm of rain annually, that continuous protection matters—especially during spring storms when intensity spikes. The interlocking design means no fasteners penetrate the exposed surface (fasteners are hidden under the overlap), eliminating the most common leak points in traditional roofing. A properly installed solid deck and ice-and-water underlayment add extra defense, and the four-way interlock distributes any lateral water movement away from seams. Homeowners report roof leaks resolve permanently once Interlock goes on.

Absolutely. Interlock offers five profiles—Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—so you can choose the architectural style that matches your home's character. Each profile is formed from the same roofing-grade aluminum alloy and receives the same Alunar 70% PVDF protection, so you're not sacrificing durability for aesthetics. Whether you want the dimensional depth of wood shake or the elegant geometry of slate, the metal substrate remains invisible to the eye. The profiles are available in multiple colors and finishes, so a Old Union home can look traditional or contemporary without revealing it's aluminum underneath.

Yes, on two counts. Interlock aluminum is approximately 95% recyclable—once your roof reaches the end of its life (which, given the lifetime warranty, may be decades away), the material returns to the aluminum supply chain rather than a landfill. That breaks the asphalt-shingle cycle, where millions of tons of oil-based waste accumulate annually. Aluminum recycling also uses 95% less energy than primary aluminum production, so choosing metal reduces your roof's embodied carbon footprint. Over the 12 freeze-thaw days Old Union experiences each year, aluminum's durability means fewer roof replacements and less material cycling through waste streams—a concrete sustainability advantage that's measured in tonnage, not marketing claims.
