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

Aluminum cannot rust because it contains no iron — the element that causes rust in steel. Instead, aluminum develops a self-healing oxide layer that protects it from moisture. Crosswinds receives about 591 mm of rain yearly, and with roughly 24 freeze-thaw cycles per year, this protection matters: as the oxide layer is scratched during installation or weather exposure, it automatically reforms. The Alunar 70% PVDF fluorocarbon coating applied to both sides of each panel adds another 30-year warranty against corrosion failure, making aluminum roofing fundamentally different from steel alternatives that require continuous maintenance to prevent rust.

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Crosswinds experiences typical daily winds around 24 km/h with gusts reaching 94 km/h — well within this rating. The interlocking system distributes wind load across the entire roof rather than relying on fasteners alone, and because the panels weigh only 0.41 to 0.59 lb/sq ft (depending on profile), they're less prone to uplift than heavier materials. This combination of light weight and mechanical interlock has proven reliable from coastal salt-air regions to extreme climates.

No structural reinforcement is required. Interlock's aluminum panels are extraordinarily light — the Mediterranean Tile profile, which replicates the heaviest traditional tile aesthetic, weighs only about 0.59 lb/sq ft and is approximately 96% lighter than concrete or clay tile. This extreme lightness means the roof can install directly over most existing structures without adding strain. Crosswinds homes built within typical local construction standards can support this material without modification. In fact, because the panels are so light, many homeowners install them over existing asphalt or wood shingles, eliminating costly tear-off and disposal — a significant advantage in a region with annual precipitation of 591 mm that may have caused older roofing to deteriorate.

Yes, reflective aluminum coatings reduce the heat absorbed by your roof and transferred into your home. Interlock's energy-efficient colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they reflect the sun's energy rather than absorbing it the way asphalt does. Over Crosswinds' 3,704 annual sunshine hours, this reflectance continuously works to keep roof temperatures lower. Cool Roof Rating Council testing confirms measurable cooling load reduction. The effect is especially valuable during summer months; combined with the roof's longevity, the energy savings compound over decades, offsetting the initial material cost.

Interlock aluminum roofing is non-combustible and available in Class A fire classification — the highest fire rating. This designation matters for insurance: many insurers offer premium discounts for Class A-rated roofs. Aluminum is inherently non-flammable because it contains no organic materials that can ignite, unlike asphalt shingles or wood shakes. The roofing is compliant with current IBC/IRC codes (ICC-ES evaluation ESR-1790, reissued 2025), and CALGreen verification confirms compliance with regional building standards. In a region with 24 freeze-thaw days per year — conditions that can crack and age asphalt shingles, exposing them to fire risk — a non-combustible aluminum roof provides consistent, code-compliant protection.

Interlock offers The Guardian warranty: a lifetime limited, non-prorated material warranty for the original homeowner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This is transferable once, giving the next owner 50 years of coverage from completion date. Because aluminum does not rust or rot and the Alunar coating is warranted 30 years against chalking and fading, the roof outlasts traditional materials in Crosswinds' variable climate — where 591 mm annual rain, 4 cm snow, and 24 freeze-thaw cycles stress conventional roofs. The longevity and transferability mean this roof is genuinely the last roof you buy and a selling asset for your home.

Aluminum roofs require far less maintenance than asphalt, wood, or tile. Unlike asphalt shingles, which curl and crack under Crosswinds' 24 annual freeze-thaw cycles and degrade under 3,704 sunshine hours per year, aluminum does not split, rot, or lose integrity over time. Wood shakes require regular treatment and inspection; concrete and clay tile develop cracks. Interlock's aluminum is CALGreen-verified for reduced maintenance, and the Alunar 70% PVDF coating resists chalking and fading without repainting. Routine maintenance amounts to occasional debris removal — the same care you'd give any roof. Because the roof is non-combustible and impact-resistant to UL 2218 Class 4 (highest hail rating), you avoid the emergency repairs that plague other materials.

Yes. Because Interlock panels weigh only 0.41 to 0.59 lb/sq ft, they install directly over most existing roofs without tear-off — saving you money and eliminating the landfill impact of an asphalt haul-away. Interlock Roofing of America, serving the region since 2014, can assess your home during a site inspection and determine whether existing decking is sound. If your current roof is deteriorating from Crosswinds' 591 mm annual rainfall and freeze-thaw stress, the installer will recommend tear-off to ensure proper ventilation and deck integrity. When installing over an existing roof, the process is faster and cleaner. The lightweight design and four-way interlocking system allow installation in most weather conditions, shortening your project timeline.

Interlock offers five distinct profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile — each engineered with four-way interlocking aluminum panels. The profiles range in weight from Shingle at 0.41 lb/sq ft to Tile at 0.59 lb/sq ft, yet all deliver authentic visual depth without the structural strain, maintenance, or longevity issues of their namesake materials. Each profile is manufactured from roofing-grade 3105-H24 or 3003-H24 aluminum alloy (ASTM B209) with Alunar 70% PVDF coating applied to both sides. The result is a roof that achieves the architectural character homeowners want while providing the durability, fire rating, and lightweight performance that Crosswinds' climate demands — rain, freeze-thaw cycles, wind gusts, and intense sunshine hours.

Aluminum roofing is approximately 95% recyclable and breaks the asphalt tear-off-to-landfill cycle that conventional roofing perpetuates. Every year, millions of tons of asphalt shingles are removed and discarded; Interlock's aluminum panels, by contrast, retain virtually all material value at end-of-life. The lightweight design also means no tear-off is required in many cases — you simply install over the existing roof, further reducing landfill impact. Because the roof lasts a lifetime and is transferable to the next owner for 50 years of additional protection, it amortizes environmental cost over an exceptionally long service period. In a region with 591 mm annual rainfall driving asphalt degradation and frequent replacements, choosing aluminum eliminates the recurring environmental debt of repeated roof cycles.

Yes. Crosswinds averages about 4 cm of snow, 591 mm of rain, roughly 24 freeze–thaw days a year, with peak wind gusts near 94 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.
