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

No. Interlock's roofing uses 3105-H24 and 3003-H24 aluminum alloy, which contains no iron and therefore cannot rust. When aluminum is scratched, its oxide layer self-heals automatically. Gillespie County's 1034 mm annual rainfall and freeze-thaw cycles that occur about 8 days per year will not corrode aluminum the way they degrade steel or wood. The Alunar 70% PVDF fluorocarbon coating on both panel sides adds another 30-year layer of protection against chalking and fading, measured to ASTM D4214 standards.

Not with Interlock. The Slate profile weighs just 0.41 lb per square foot, and the Mediterranean Tile profile—about 96% lighter than concrete or clay tile—installs at 0.59 lb per square foot. This extraordinary lightness means no structural reinforcement is required, and installation can go directly over most existing roofs. For Stonewall homes already carrying an asphalt layer and dealing with 88 km/h wind gusts, the reduced load actually improves structural performance during storms.

Yes. Interlock's energy-efficient colors feature thermal emissivity of 0.84 and initial solar reflectance up to 0.55, reflecting the heat that asphalt absorbs and keeping it off your air-conditioning system. With Stonewall averaging 3325 sunshine hours per year, that reflective benefit compounds daily. Cool Roof Rating Council verification confirms the energy savings are real and measurable, not marketing claims.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for 50 years from completion, giving you permanent peace of mind and a major selling point. With an ICC-ES ESR-1790 evaluation and installations spanning from 1998 to today, across salt-air coasts and Antarctic research stations, the product has decades of proven real-world performance.

Five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each uses four-way interlocking aluminum panels, so you get the architectural character you want without the weight penalties or maintenance headaches of the original materials. Whether your home's design calls for traditional slate or Texas-style tile, Interlock manufactures the panels in Delta, BC, with the same non-corrosive 3003-H24 / 3105-H24 aluminum alloy and Alunar coating in every profile.

Virtually none compared to asphalt, wood, or clay tile. With no organic materials, there's no rot, splitting, or moss growth to manage. Stonewall's average 1034 mm of rain annually will rinse away dust and debris naturally. A solid deck plus underlayment under the panels keeps it acoustically quiet—asphalt-quiet, not loud. The CALGreen-verified design actually reduces maintenance obligations, freeing you from the cycle of patching and re-coating that traditional roofs demand.

Installation timelines vary by roof size, but Interlock Roofing of America, serving the region since 2014, handles the complete process efficiently. The metal panels install directly over most existing roofs—no tear-off required—which saves time, labor, and the cost of hauling asphalt to landfill. The four-way interlocking system ensures a tight seal against Stonewall's 88 km/h gusts and 1034 mm annual rainfall. Your installer will confirm timeline when they assess your home's specifics.

No. The four-way interlocking panel design, combined with a solid deck and underlayment, creates a redundant seal system that handles Stonewall's 1034 mm annual rainfall and occasional heavy downpours. The aluminum panels themselves are non-porous and will not absorb water or warp. When installed to specification by Interlock Roofing of America, the overlapping seams and interlocks direct water down and away, just as they have in coastal salt-air environments since 1998.

Yes. Interlock offers Class A fire-rated profiles using non-combustible aluminum that meets ICC-ES ESR-1790 (IBC/IRC, reissued 2025) and UL standards. Since aluminum contains no iron and cannot support combustion, you gain the highest fire classification available—critical for Texas wildfire seasons and insurance peace of mind. The non-combustible rating also qualifies for certain CALGreen building credits in some jurisdictions.

Absolutely. Interlock's aluminum is approximately 95% recyclable, so when your roof eventually reaches end of life—decades from now—it enters the recycling stream as a valuable material, not a landfill. Asphalt shingles, by contrast, must be torn off every 15-20 years and hauled away. Over the lifetime of your home, choosing aluminum ends the repeated tear-off cycle, reducing waste and environmental impact while delivering a roof you'll likely never need to replace.
