Metal Roofing in Merritt Island, Florida — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum cannot rust because it contains no iron—the chemical element that oxidizes in salt air. Instead, aluminum develops a microscopic oxide layer that actually heals itself when scratched, even in the corrosive coastal environment. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) is coated with Alunar 70% PVDF fluorocarbon finish on both sides, warranted 30 years against chalking and fading. With Brevard County's 1551 mm of annual rainfall and salt-spray exposure, this dual-coat system keeps aluminum roofs installed since 1998 performing identically from Delta, BC to Antarctic research stations.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification, and they carry Florida Product Approval FL7263-R7 under the 2023 Florida Building Code, tested to UL 580 and TAS 125 uplift standards. Brevard County's typical gusts reach 165 km/h—well within that capacity. The interlocking design distributes wind load across the entire panel system rather than relying on fasteners alone, so your roof stays secure during the peak storm season without requiring additional reinforcement or expensive structural modifications.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Many insurers offer discounts for impact-rated roofing because claims are rare. In Brevard County's subtropical climate with zero freeze-thaw days annually, impact damage is your main weather concern, and Class 4 aluminum outlasts asphalt shingles that dent, crack, or lose granules under the same conditions. Contact your insurer with the UL 2218 rating to explore premium reductions; the durability typically pays for itself.

Metal roofing's energy benefit depends on color and finish. Interlock offers energy-efficient colors with thermal emissivity of 0.84 and initial solar reflectance up to 0.55—measured per ASTM D2244—meaning these coatings reflect heat that asphalt absorbs and traps. Over Merritt Island's 3631 annual sunshine hours, a reflective aluminum roof stays cooler during peak afternoon temperatures than dark asphalt, reducing the load on your air conditioning. The magnitude of savings varies by color choice and your home's insulation, but the Cool Roof Rating Council rating confirms the physics: aluminum reflects, asphalt radiates.

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's also one-time transferable to the next owner for 50 years from completion, making it a significant resale asset. Unlike prorated warranties that decline yearly, you're protected equally in year one and year thirty. The lifetime coverage on the original owner eliminates the anxiety of asphalt shingles lasting 15–20 years before full replacement; aluminum installed to spec will outlast your ownership, and the transfer term protects the buyer's investment too.

In most cases, no structural work is needed. Interlock's Slate profile installs at just 0.41 lb/sq ft, the Shake at 0.58, and the Mediterranean Tile at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. This extraordinary lightness allows installation directly over most existing asphalt roofs without reinforcement, saving thousands in decking and framing upgrades. Brevard County's zero freeze-thaw cycles mean your existing roof hasn't weakened from ice damage, so the substrate is typically sound. Your local Interlock installer will inspect the deck during the estimate; in the vast majority of Merritt Island homes, the answer is 'yes, as-is.'

Significantly less. Aluminum panels don't split, rot, or curl—issues that plague wood and asphalt shingles in Florida's humid subtropical environment. They don't crack under the 1551 mm of annual rainfall or need frequent resealing like slate or clay tile. The Alunar coating (30-year fade warranty, ASTM D4214 tested) resists the UV damage that breaks down asphalt binders, and the non-combustible aluminum and interlocking design shed debris naturally. Most homeowners rinse the roof annually if near salt air; otherwise, routine gutter cleaning is your main task. The result: a CALGreen-verified roof requiring reduced maintenance versus asphalt shingles that demand granule replacement or tile that needs mortar repointing.

Yes. Interlock manufactures five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each is precision-formed from the same roofing-grade aluminum with the Alunar fluorocarbon finish applied to both sides. The profiles replicate the dimensional texture and shadow-lines of their namesakes, and the color palette includes aged metallics, earth tones, and pastels. From street view, the dimensional detail and finish are visually consistent with high-end architectural materials. The trade-off: you get the authentic appearance while gaining aluminum's 120 mph wind warranty, Class 4 hail rating, and non-combustible rating—attributes no traditional slate, shake, or tile can legally warrant.

Substantially. Interlock aluminum is approximately 95% recyclable at end-of-life, and because aluminum doesn't degrade like asphalt binders, it won't need replacement for decades. When you finally recycle the panels—if ever—they have genuine scrap value. Asphalt shingles, by contrast, are torn off every 15–25 years and sent to landfills by the millions, where they persist and release hydrocarbons. Over Merritt Island's 1551 mm annual rainfall, your asphalt roof weathers faster, accelerating the tear-off cycle. Choosing aluminum ends that cycle for your ownership and beyond. The material is manufactured in Delta, BC—a regional supply that reduces transport emissions—and requires no chemical reroofing treatments that asphalt demands.

Installation timelines depend on your roof's complexity and weather, typically 3–7 business days for a standard residential home. Because Interlock panels are so light (0.41–0.59 lb/sq ft), installation crews work efficiently without structural delays. More importantly, you can install over existing asphalt shingles, so there's no day when your home is unprotected. The old shingles stay in place until the new aluminum roof is underway; you don't wait for decking repair or experience rain exposure during tear-off. The local Interlock Roofing of America team, serving Brevard County since 2014, will walk you through the schedule during the estimate and coordinate around Merritt Island's frequent rain events to keep the job dry and on track.
