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

Aluminum cannot rust because it contains no iron—the metal that oxidizes. Instead, aluminum naturally forms a self-healing oxide layer that protects it even when scratched. In Tours, where you experience about 13 freeze-thaw days per year, that protection matters: the oxide layer seals itself after damage, preventing the rust-and-rot cycle that steel and asphalt can't escape. Add Interlock's two-sided Alunar 70% PVDF fluorocarbon finish (30-year warranty), and your roof stays protected through repeated freeze cycles without the maintenance burden.

Your roof is engineered with four-way interlocking aluminum panels that overlap like shingles, so water runs off rather than pooling. Tours receives about 1109 mm of rainfall annually—roughly double the US average—so the interlock design is critical. Water travels down the slope and out through the seams without penetrating them. Installation over a solid deck with underlayment (standard practice) adds a second water barrier, giving you the same leak protection as an asphalt roof but without the breakdown asphalt experiences as rain erodes its surface over 15–20 years.

No structural reinforcement needed. Interlock's Mediterranean Tile profile weighs just 0.59 lb/sq ft—about 96% lighter than real concrete or clay tile—so it installs safely over most existing wood or asphalt roofs without engineering upgrades. Real tile can weigh 10–15 lb/sq ft and requires rafter reinforcement costing thousands. In Tours, where you're not battling heavy wet snow (only about 2 cm annually), the aluminum tile profile slides onto your current structure, saving you both money and months of prep work while delivering the curb appeal of heavy masonry.

Yes, if you choose an energy-efficient color. Interlock's reflective coatings achieve up to 0.55 solar reflectance (Aged Copper Penny) and 0.84 thermal emissivity, meaning they bounce heat away instead of absorbing it like dark asphalt does. Tours gets about 3384 sunshine hours per year, so that reflection adds up: your roof stays cooler, your AC runs less, and utility bills drop. The Cool Roof Rating Council rating confirms the difference. Over a 50-year roof life, the energy savings often pay back a portion of the material cost.

The Guardian lifetime limited warranty covers the original owner for the entire roof's life—no prorations—against rusting, rotting, splitting, cracking, curling, and even perforation from hailstones up to 1.5 inches (UL 2218 Class 4 rating). The warranty transfers once to the next owner, protecting them for 50 years from completion. That's the only transferable metal roof warranty of its kind. In Tours, where aluminum oxide self-heals and the Alunar coating resists 30 years of fade, your roof typically outlasts 3–4 asphalt replacements without decline in structural performance.

Aluminum is non-combustible, and Interlock offers Class A fire classification (ICC-ES ESR-1790, reissued 2025)—the highest rating available. Unlike asphalt shingles, which can ignite and spread flame, or wood shakes, which are highly flammable, aluminum won't ignite or contribute fuel to a fire. For homeowners in Texas communities evaluating fire risk, Class A compliance can lower insurance premiums and provides genuine peace of mind. Your roof becomes a fire barrier rather than a fuel source.

Very rarely. Unlike asphalt, which loses granules and weakens within 15 years, or wood shakes, which rot in Tours' 13 annual freeze-thaw days and ~1109 mm rain, aluminum requires no sealing, patching, or moss treatment. The Alunar two-sided finish resists weathering and is backed by a 30-year coating warranty. Most owners simply let rain rinse debris; occasional leaf clearing after fall is all that's needed. With CALGreen verification for reduced maintenance, Interlock delivers durability without the upkeep cycle that drains time and money.

Installation over existing roofing is one of metal's biggest advantages. Because Interlock panels weigh as little as 0.41–0.59 lb/sq ft (even the Tile profile), they install directly over old asphalt without tearing off, removing nails, or paying landfill fees. Your existing roof becomes additional insulation and leak protection. Interlock Roofing of America, serving Tours since 2014, assesses your deck and confirms whether overlay is safe; if not, removal is straightforward and faster than asphalt replacement. Most installations complete in days, not weeks.

Aluminum is approximately 95% recyclable and never ends up in a landfill the way asphalt does. Tours homeowners who choose Interlock stop the cycle of tearing off old shingles—millions of pounds annually in Texas alone—and sending them to waste. When your metal roof eventually reaches end of life (unlikely for 50+ years), the aluminum recycles into new products indefinitely without losing properties. That's genuine sustainability: one metal roof replaces 3–4 asphalt roofs over a century, eliminating the environmental cost of repeated manufacturing and disposal.

Yes. Asphalt costs less upfront but fails within 15–20 years; you'll replace it 3–4 times over 60 years. Each replacement tears off landfill, pays labor twice, and interrupts your life. Interlock's lifetime warranty (original owner) eliminates that cycle—you buy once. When you factor in the cost of 3–4 asphalt replacements, the energy savings from reflective coatings, insurance discounts for Class A fire rating, and zero maintenance, the aluminum roof is cheaper in total cost of ownership. Tours homeowners who keep their house 20+ years break even in year 12–15; beyond that, it's pure savings.

Yes. Tours averages about 2 cm of snow, 1109 mm of rain, roughly 13 freeze–thaw days a year, with peak wind gusts near 89 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.
