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

Aluminum rusts chemically only when iron is present in the metal—and our roofing panels contain zero iron. The aluminum alloy (3105-H24 / 3003-H24 per ASTM B209) forms a transparent oxide layer on its surface that self-heals when scratched, blocking further oxidation. That's why Interlock panels installed in coastal salt-air environments and Antarctic research stations hold up without the corrosion problems that plague steel. In Van Raub, with about 1046 mm of annual rainfall and wind gusts to 103 km/h, this oxide barrier means your roof won't weaken or stain from water exposure the way steel would.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation damage from hailstones up to 1.5 inches. That rating comes from rigorous impact testing and translates to real durability in storm-prone areas. Homeowners should contact their insurance carrier to ask about discounts; many insurers recognize Class 4 impact resistance and offer premium reductions. Van Raub averages about 7 freeze-thaw days yearly, which stresses roof materials, but the aluminum's flexibility and impact strength handle that cycling better than brittle asphalt or ceramic tile.

Yes. The Interlock Shake profile weighs just 0.58 lb/sq ft and the Mediterranean Tile profile about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. That extreme lightness means most homes can accept an overlay without structural modifications. Compare that to traditional tile, which forces costly beam reinforcement, and to the cumulative weight of multiple asphalt re-roofing cycles. In Kendall County, where Van Raub sits, this weight advantage eliminates the guesswork: you install over your existing roof, avoid the demo cost and landfill trip, and still get a roof with a lifetime limited warranty from the original owner.

energy-efficient colors on Interlock panels achieve solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they reflect heat that asphalt shingles absorb and re-radiate into your attic. The Cool Roof Rating Council rating confirms that performance. Van Raub receives about 3354 sunshine hours annually—plenty of energy to save if you're reflecting rather than absorbing it. The cooler attic translates directly to lower air-conditioning demand through summer. Not every color offers energy-efficiency certification, so choose wisely at design time, but the reflective benefit compounds year after year across the roof's 50+ year life.

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 a 50-year term from completion, which appeals to buyers and protects your home's value. The Alunar 70% PVDF fluorocarbon finish carries its own 30-year coverage against chalking and fading (ASTM D4214 / D2244 measured). With panels manufactured since 1998 still performing in the field, and Van Raub's moderate climate of roughly 1046 mm rain and 2 cm snow annually, you're looking at a roof that outlasts multiple asphalt cycles and asks little in return.

The four-way interlocking panel design and edge details warrant resistance to wind speeds up to 120 mph (193 km/h) when installed to specification. Van Raub's typical daily-maximum winds run about 18 km/h, with gusts recorded to 103 km/h—well within the rated capacity. The interlock system means each panel locks to its neighbors on all four sides, distributing wind loads evenly across the roof rather than relying on fasteners to hold individual panels in place. That distributed strength is why Interlock installations have performed in hurricane zones and mountain passes. Your installer, Interlock Roofing of America, has served this region since 2014 and knows exactly how to secure panels for local wind patterns.

Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each one uses the same four-way interlocking aluminum panels but in different shapes and surface patterns so your roof reads as traditional material from the street. The profiles are available in multiple colors to further match slate gray, copper penny, or clay. The lightweight advantage—about 96% lighter than real tile—lets you have the architectural look without the structural headache. In Van Raub's Kendall County aesthetic, you choose the visual character that suits your home while keeping the durability, 3354 annual sunshine hours of reflective protection, and a roof that lasts a lifetime instead of 15–20 years.

The math favors metal over a 50-year horizon. Asphalt requires replacement every 15–20 years, meaning you'll buy and install 3–4 roofs in the time one Interlock roof serves you. Each re-roofing cycle incurs demo labor, landfill fees, new underlayment, and reinstalled gutters. Metal carries no such restart costs: the Alunar coating holds for 30 years, the aluminum never rusts, and the four-way interlocking system eliminates fastener corrosion problems. Add in the transferable warranty—which adds 50 years of coverage for the next owner—and resale appeal, and the long-term cost per year drops below asphalt. Van Raub's moderate rainfall of 1046 mm annually and 7 freeze-thaw days mean less weather-driven premature failure, so you keep your metal roof longer without surprise repairs.

Interlock Roofing of America has served Van Raub and Kendall County since 2014, giving them a decade of field experience with local climate, building codes, and homeowner preferences. They understand the region's rainfall patterns (about 1046 mm per year), occasional freeze-thaw cycles (roughly 7 days annually), and wind gusts to 103 km/h. The installer can walk you through profiles, colors, and whether an overlay or full replacement makes sense for your home. They'll pull permits, coordinate with your existing contractor if needed, and warranty the installation to match the Guardian Warranty terms. Having a local team means accountability, service visits if questions arise, and someone who knows Kendall County homes inside and out.

Virtually none. Asphalt requires annual inspection, gutter cleaning, and algae treatment; wood shakes need re-staining and rot monitoring; clay tile cracks and needs individual replacement. Interlock aluminum panels resist algae growth, don't split or curl, shed debris cleanly, and the Alunar fluorocarbon finish resists chalking and fading for 30 years. CALGreen verification includes reduced maintenance as a sustainability benefit. Van Raub's 1046 mm annual rainfall and 3354 sunshine hours won't degrade the aluminum's oxide layer or the coating—rain actually helps keep it clean. Over a 50-year life, you avoid the cumulative cost and time of the repairs that plague softer materials, leaving you more time and money for the rest of your home.

Yes. Van Raub 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.
