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

No—aluminum cannot rust because it contains no iron. Instead, it forms a microscopic oxide layer that actually heals itself when scratched or damaged. In Trafalgar's warm, humid climate with about 1317 mm of annual rainfall and salt air exposure, this self-healing oxide is a real advantage over steel roofs, which do rust. The roofing-grade 3105-H24 aluminum alloy in Interlock panels is the same material used on coastal homes and even an Antarctic research station. That proven track record matters when you're near salt water.

Yes, if it's installed properly. Trafalgar experiences gusts up to 197 km/h, and Interlock's four-way interlocking panels are designed to handle exactly that—the system is warranted for wind speeds up to 120 mph (193 km/h) when installed to specification. The panels lock together on all four edges so wind can't get underneath and lift them off. The roof passed Florida Product Approval testing under UL 580 and UL 1897 wind uplift standards for the 8th Edition Florida Building Code. That's not theoretical; it's field-proven engineering.

Aluminum roofs handle hail better than asphalt or tile. Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Trafalgar's 3784 annual sunshine hours and warm climate mean hail is less common here than in plains states, but when it does occur, the nonporous aluminum absorbs the impact without cracking or splitting like slate or wood. Some insurers offer discounts for Class 4-rated roofs. It's worth asking your agent.

Yes. Interlock's energy-efficient colors reflect heat rather than absorbing it the way asphalt does. The Aged Copper Penny finish, for example, has initial solar reflectance up to 0.55 and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. With Trafalgar averaging 23.8°C year-round and 3784 sunshine hours annually, that reflectance keeps less heat entering your attic and your air conditioner running less. The metal itself conducts heat without storing it, unlike asphalt shingles. Over a 20- or 30-year roof life, the cooling savings can be substantial.

Usually no. Interlock panels are extraordinarily light—the Shingle profile installs at just 0.41 lb/sq ft and the Mediterranean Tile at 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Most existing roof structures can handle that additional load without reinforcement. In fact, the light weight is one reason you can often install metal panels directly over your existing asphalt roof instead of tearing it off and hauling it to a landfill. Your local Interlock installer, serving the region since 2014, can assess your specific roof during a site visit to confirm no structural work is needed.

Interlock's 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, who receives 50 years of coverage from completion. Because aluminum doesn't degrade like asphalt—which breaks down from Trafalgar's 3784 annual sunshine hours—or wood shakes, which split in freeze-thaw cycles, the roof typically outlasts the house. That transferability adds real value when you sell.

Over the life of your home, yes. Asphalt requires tear-off and replacement every 15 to 20 years, each time generating landfill waste and labor costs. Interlock is a single installation that lasts the life of the house with minimal maintenance. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading, and the underlying aluminum doesn't degrade. When you factor in three or four asphalt replacements versus one metal roof, plus no storm damage claims for impact, the total cost of ownership favors aluminum. For Trafalgar homeowners, it's the last roof you'll buy.

Yes—that's what Interlock specializes in. Choose from five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each one replicates the appearance of the traditional material it mimics, using four-way interlocking aluminum panels in roofing-grade 3105-H24 alloy. The panels are painted with a Alunar 70% PVDF fluorocarbon finish applied to both sides (extra protection in salt-air environments), available in a range of colors. You get the authentic look you want with the durability and zero-rust properties of aluminum.

Aluminum roofs are the lowest-maintenance option. Unlike asphalt, they don't shed granules or develop moss in Trafalgar's humid, wet climate (1317 mm rain annually). Unlike wood shakes, they don't split or rot. Unlike concrete tile, they're not porous and don't absorb water. Interlock's CALGreen-verified design confirms reduced maintenance needs. Routine care—occasional gutter cleaning and debris removal—is all most homeowners do. The Alunar coating resists fading for 30 years, so repainting isn't necessary. Over time, the minimal upkeep makes aluminum far more practical than materials that degrade.

No, if the roof is designed and installed for it. Trafalgar receives about 1317 mm of rain per year, and metal roofs shed water faster than any other roofing material because water runs off smooth aluminum instead of pooling in porous shingles. The four-way interlocking panels are engineered so water can't get between panels—it flows down the slope. Pair that with a solid deck and underlayment (installed to ICC-ES ESR-1790 specification), and leaks are no more common in metal than in asphalt. In fact, the speed of water shedding is a major advantage in wet climates.
