Common Myths About Metal Roofs in Florida Debunked
Mar 24, 2025Metal roofs have gained significant popularity in Florida due to their durability, energy efficiency, and aesthetic appeal. However, many myths and misconceptions continue to circulate, making some homeowners hesitant to consider this roofing option. In this blog, we will debunk the most common myths about metal roofs in Florida and help you make an informed decision for your home.
Myth 1: Metal Roofs Attract Lightning
One of the most prevalent myths about metal roofs is that they attract lightning. This misconception arises from the fact that metal is a good conductor of electricity. However, the truth is that metal roofs do not increase the likelihood of a lightning strike. Instead, if lightning does strike a metal roof, it is dispersed safely across the structure and into the ground, reducing the risk of fire compared to other roofing materials such as asphalt shingles or wood.
Myth 2: Metal Roofs Make Homes Hotter
Florida’s intense heat makes homeowners wary of roofing materials that could increase indoor temperatures. Some believe that metal roofs absorb and retain more heat than other roofing materials. In reality, metal roofs reflect a significant amount of solar radiation, reducing heat absorption. Many metal roofing systems come with cool roof coatings that enhance their reflective properties, making them one of the most energy-efficient options available.
Myth 3: Metal Roofs Are Noisy During Rain
Many people assume that a metal roof will be significantly louder during a rainstorm than traditional roofing materials. However, this is not the case. When properly installed with underlayment and insulation, metal roofs produce no more noise than asphalt shingles. The misconception likely comes from experiences with barns or older metal structures that lack proper insulation.

Myth 4: Metal Roofs Rust Easily
Given Florida’s humid and coastal climate, rust is a major concern for homeowners. Some believe that metal roofs will rust quickly when exposed to moisture. However, modern metal roofing materials are treated with protective coatings such as galvanized or Galvalume coatings, which prevent rust and corrosion. With proper maintenance, metal roofs in Florida can last for decades without rust issues.
Myth 5: Metal Roofs Are More Expensive Than Other Roofing Options
While the initial cost of a metal roof can be higher than traditional shingles, it is important to consider long-term savings. Metal roofs have a longer lifespan—often 40 to 70 years—compared to asphalt shingles, which typically last 15 to 30 years. Additionally, metal roofs require less maintenance, offer better energy efficiency, and can lower insurance premiums due to their durability. Over time, these benefits make metal roofs a cost-effective investment.
Myth 6: Metal Roofs Can’t Withstand Hurricanes
Florida is prone to hurricanes, and homeowners need roofing materials that can withstand extreme weather conditions. Some believe that metal roofs are easily lifted by high winds. However, metal roofs are among the most wind-resistant options available. When properly installed, metal roofing can withstand wind speeds of up to 140-180 mph, meeting or exceeding Florida’s strict building codes. Additionally, metal panels interlock, reducing the risk of wind uplift compared to traditional shingles.

Myth 7: Metal Roofs Are Difficult to Maintain
Some homeowners worry that metal roofs require excessive maintenance. The truth is that metal roofs require less maintenance than traditional roofing materials. Regular inspections and occasional cleaning are usually sufficient to keep a metal roof in excellent condition. Unlike shingles, metal does not crack, curl, or deteriorate over time, reducing the need for frequent repairs.
Myth 8: Metal Roofs Look Industrial and Unattractive
Another common myth is that metal roofs are only suitable for commercial buildings or industrial settings. In reality, modern metal roofing comes in a variety of styles, colors, and finishes that can complement any home’s architecture. Metal roofs can mimic the appearance of traditional shingles, tiles, or even wood shakes, providing homeowners with a stylish and durable roofing solution.
Myth 9: Metal Roofs Interfere with Cell Phone and Wi-Fi Signals
There is a misconception that metal roofs disrupt cell phone and Wi-Fi signals, making it difficult to use mobile devices indoors. However, metal roofing does not interfere with signal reception any more than other building materials like brick or stucco. If a home experiences signal issues, it is likely due to factors such as distance from cell towers, thick walls, or electronic interference from other devices rather than the metal roof itself.

Myth 10: Metal Roofs Can’t Be Installed Over Existing Roofs
Many homeowners believe that a metal roof requires a complete tear-off of the existing roof. While it is true that in some cases a tear-off may be necessary, metal roofing is often lightweight enough to be installed over an existing shingle roof. This process can save time, reduce labor costs, and minimize waste, making metal roofing an environmentally friendly option.
