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

No — aluminum cannot rust because it contains no iron. Instead, it forms a self-healing oxide layer that protects the metal underneath; if scratched, this layer reforms automatically. Flo gets about 1182 mm of annual rainfall and gusts up to 91 km/h, both conditions that would accelerate rust on steel, but aluminum simply oxidizes to a stable, harmless gray patina. The Alunar 70% PVDF fluorocarbon finish (applied to both sides) adds another 30-year warranty layer, so corrosion isn't a maintenance issue here like it is with conventional steel.

Over 40–50 years, aluminum costs less per year because you install it once and never reroof. Asphalt shingles last 15–20 years in climates like Flo's (1182 mm rain, 10 freeze-thaw days annually), meaning two or three replacement cycles, plus labor and disposal fees each time. The Guardian warranty is lifetime limited and non-prorated for the original owner, then transfers for 50 years to the next owner — that's the only roof you'll ever buy. When you factor in no tear-offs going to landfill and no storm repairs from hail or the 91 km/h gusts we see, the math favors aluminum.

No structural reinforcement is needed, even with the heaviest Interlock profile. The Mediterranean Tile style installs at about 0.59 lb/sq ft — roughly 96% lighter than concrete or clay tile — so it actually reduces load on your home. Interlock panels can install directly over your existing asphalt roof in most cases, saving the cost and mess of a tear-off. With Flo's 91 km/h wind gusts and 10 freeze-thaw cycles per year, a lighter roof that won't stress your frame during temperature swings and wind events is a practical advantage.

Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h), well above Flo's typical 91 km/h gusts. On impact, the roof carries a UL 2218 Class 4 rating — the highest available — and the warranty covers perforation from hailstones up to 1.5 inches. The interlocking design means panels are mechanically fastened in four directions, so wind that might lift and separate shingles simply locks the panels tighter together.

Yes. energy-efficient Interlock colors reflect heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84 — both rated by the Cool Roof Rating Council. Flo receives about 3362 sunshine hours per year and average temperatures around 20.4°C, so a reflective roof reduces the heat gain that drives air conditioning in summer. Aluminum also conducts heat differently than asphalt, which absorbs and re-radiates warmth into the attic; over a 40-year lifespan, that cooling savings compounds significantly.

Almost none. Unlike asphalt shingles that crack and curl, wood shakes that split, or clay tiles that need sealing, aluminum doesn't degrade from weather. The 30-year Alunar fluorocarbon finish resists chalking and fading (measured to ASTM D4214 and D2244 standards), and The Guardian warranty covers splitting, cracking, curling, and loss of impact resistance. Flo's 1182 mm rain and 10 annual freeze-thaw cycles would normally stress traditional roofing; aluminum simply sheds water and moves with temperature swings without damage.

Yes — Interlock manufactures five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the texture and shadow lines of the traditional material it mimics, so you can choose the aesthetic your home needs. The aluminum construction delivers the durability advantage (Class A fire rating available, non-combustible, zero maintenance) without the brittleness of real slate, the rot risk of cedar, or the weight and cost of concrete or clay tile — which this roof replicates at 96% lighter.

Interlock Roofing of America, your local installer since 2014, can install over most existing asphalt roofs, eliminating a tear-off and saving time and money. The lightweight panels (Shingle profile at 0.41 lb/sq ft, others similarly light) install faster than traditional materials, typically in days rather than weeks depending on roof size. Because the panels interlock four ways and fasten mechanically, installation is precise and weather-resistant from day one — no exposed nails, no gradual seal degradation.

Yes, materially. Aluminum is approximately 95% recyclable and doesn't degrade into toxic byproducts; at end of life, the entire roof can be recycled. Asphalt shingles, by contrast, generate millions of tons of landfill waste annually because they cannot be recycled economically. Over Flo's typical two or three asphalt reroof cycles in 40–50 years, you'd send 20–30 tons of shingle waste to the landfill; one Interlock roof lasts that entire period, then recycles. CALGreen-verified for reduced maintenance also means fewer service trucks and no chemical treatments.

The Guardian is a lifetime limited, non-prorated warranty for the original owner — it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no diminishing payouts over time. It transfers once to the next owner for 50 years from completion, preserving value through a resale. Few roofing products offer non-prorated coverage; combined with the 30-year fluorocarbon finish warranty and the fact that aluminum cannot rust or rot, this warranty is credible because the material itself resists the failures asphalt and wood suffer through Flo's 1182 mm rain and freeze-thaw cycles.
