Metal Roofing in Lake Washington, Florida — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum simply cannot rust because it contains no iron—rust only forms when iron oxidizes. Instead, aluminum develops a thin oxide layer that self-heals when scratched, protecting the metal underneath. In Brevard County's salt-air environment with 1532 mm of annual rainfall, this matters: steel roofs corrode from inside out in coastal climates, but aluminum's chemistry makes it immune. Interlock's 3105-H24 and 3003-H24 alloy is roofing-grade aluminum with a Alunar 70% PVDF finish applied to both sides, warranted 30 years against corrosion-related chalking and fading.

Brevard County experiences typical gusts around 143 km/h, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The interlocking design distributes wind load across the whole roof rather than loading individual fasteners. This meets Florida Product Approval FL7263-R7 testing under UL 580 and UL 1897 wind-uplift standards. With zero freeze-thaw days annually in Lake Washington, you're not fighting ice expansion—you're just managing wind, where aluminum's light weight and mechanical interlock excel.

Metal roofs with energy-efficient coatings reflect heat instead of absorbing it like asphalt does. Interlock's qualifying colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. With Lake Washington averaging 3652 sunshine hours annually and no winter heating load to worry about (0 freeze-thaw days), summer cooling is your main cost driver. Reflective aluminum roofing keeps that heat off your air conditioner, reducing cooling loads during the brutal months.

Interlock holds a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. That's the ceiling for hail impact resistance. Many insurers recognize this durability and offer premium discounts on metal roofs; contact your agent with the UL 2218 rating to inquire. Brevard County sees occasional severe weather, and lightweight aluminum that won't dent or puncture under standard hail offers real peace of mind and potentially real savings on your policy.

Asphalt typically lasts 15–20 years in Florida's heat and sun; metal roofing lasts 50+ years and carries a lifetime limited non-prorated material warranty for the original owner. Over a single ownership, you replace asphalt 2–3 times while metal sits. The math favors metal: one installation cost versus three tear-off, disposal, and reinstall cycles. With 1532 mm of rain annually and intense sun year-round, asphalt deteriorates faster in Brevard County than in drier climates. Interlock's Guardian Warranty, transferable for 50 years from completion, also adds equity if you sell.

No structural reinforcement is needed. Interlock's Tile profile weighs about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—and the Shingle runs just 0.41 lb/sq ft. Most homes can support metal roofing over an existing roof without modification. Florida Product Approval FL7263-R7 confirms this for the state's building code. Because Brevard County experiences no freeze-thaw cycles (0 days annually), you avoid the structural stress that ice buildup causes in northern climates, making aluminum's light weight purely an advantage.

Installation timeline depends on roof size and complexity; ask Interlock Roofing of America, the local installer serving Lake Washington since 2014, for a specific estimate. Yes, you can install over most existing roofs because aluminum panels are so light that structural upgrade is rarely needed. Installation over existing material saves disposal costs and time compared to full tear-off. With Lake Washington averaging 3652 sunshine hours annually, your installer will have good weather windows. The process is straightforward: Interlock panels are mechanically fastened and interlocked in place.

Metal roofs require virtually no ongoing maintenance—no replacement shingles, no sealing, no mold scraping. Annual inspection is recommended to clear debris from gutters and valleys, but the roof itself won't curl, split, crack, or rot like asphalt, wood shake, or clay tile do. Lake Washington's 1532 mm annual rainfall means good drainage is key; metal's smooth surface sheds water quickly and doesn't retain moisture like asphalt does. The Guardian Warranty covers splitting, cracking, and curling, confirming that Interlock's aluminum won't degrade the way traditional roofing materials do in humid coastal climates.

Aluminum is non-combustible and Class A fire-rated when installed correctly, the highest fire classification available. Interlock holds ICC-ES evaluation ESR-1790 (reissued 2025 for IBC/IRC codes) confirming fire performance and CALGreen verification for reduced maintenance. With Florida's risk of brush fires during dry seasons and Brevard County's coastal development density, non-combustibility matters. Aluminum cannot ignite or contribute fuel to fire spread the way asphalt or wood shake can. This non-combustible construction is also a selling point for homebuyers and may interest your insurance carrier.

Interlock aluminum is approximately 95% recyclable at end of life; asphalt shingles end up in landfills by the millions of tons annually. Over 50+ years, a metal roof eliminates the landfill cycle entirely—asphalt roofs typically require 2–3 tear-off and disposal cycles. Aluminum alloy 3105-H24 and 3003-H24 is manufactured to ASTM B209 standards and made in Delta, BC since 1998, installed from coastal salt-air homes to an Antarctic research station. Brevard County's 1532 mm of annual rainfall accelerates asphalt degradation; choosing a 50-year product avoids that waste stream.
