Metal roofing has become increasingly popular in Florida, but persistent myths prevent some homeowners from considering it. Let's address the most common misconceptions with actual facts about how metal roofs perform.
Myth #1: Metal Roofs Are Noisy When It Rains
The Reality: This is probably the most common metal roof myth, and it's understandable—we've all heard rain on a barn roof or carport. But residential metal roofing is installed over solid decking with underlayment, not directly on open purlins.
Studies have shown properly installed metal roofing is no louder than asphalt shingles—the solid deck and underlayment absorb sound. Many homeowners report finding the soft sound of rain on metal pleasant, not disturbing.
The key is 'properly installed.' Metal roofing on a home includes:
- Solid plywood or OSB decking
- Synthetic underlayment
- Air gaps between metal and decking
This construction dampens sound to levels comparable to other roofing types.
Myth #2: Metal Roofs Attract Lightning
The Reality: Metal roofing does not attract lightning. Lightning strikes based on height, terrain, and electrical charge paths—not the material of your roof. A metal roof is no more likely to be struck than any other type.
In fact, metal roofing may be safer in a lightning event:
- Metal is non-combustible, so it won't catch fire if struck
- Metal spreads electrical energy over a large area, dissipating it safely
- Metal roofs meet all building codes for electrical safety
Lightning rods work precisely because metal conducts and safely grounds electrical energy. Your metal roof would do the same if struck.
Myth #3: Metal Roofs Dent Easily
The Reality: Modern residential metal roofing is surprisingly dent-resistant. Quality standing seam panels are formed from 24 or 26-gauge steel with ribbed profiles that add significant rigidity.
Normal hail typically doesn't damage residential metal roofing. In fact, many metal roofing products carry Class 4 impact ratings—the highest available—qualifying for insurance discounts in hail-prone areas.
The caveat: Extreme hail or large falling branches can dent any roofing material. But metal's dent resistance is generally superior to tile (which cracks), slate (which chips), and shingles (which bruise internally).
Myth #4: Metal Roofs Make Houses Hotter
The Reality: The opposite is true. Metal roofs with reflective coatings are among the coolest roofing options available.
- Metal with light colors reflects solar radiation
- Premium coatings like Kynar 500 reflect up to 70% of infrared energy
- Metal doesn't absorb and store heat like asphalt or concrete tile
Studies in Florida have shown that metal roofs can reduce cooling costs by 10-25% compared to asphalt shingles. Metal's reflectivity is a significant advantage in our climate.
Myth #5: Metal Roofs Rust Quickly
The Reality: Modern metal roofing is engineered for corrosion resistance. Most residential metal roofing uses:
- Galvalume® coating (aluminum-zinc alloy) that's 2-4 times more corrosion-resistant than galvanized steel
- Factory-applied paint systems like Kynar 500 that protect for 40+ years
- Aluminum or stainless steel options for coastal areas
Proper material selection based on environment ensures decades of rust-free performance. In Central Florida, galvalume-coated steel performs excellently. Coastal properties may need aluminum or enhanced coatings.
Myth #6: Metal Roofs Are Too Heavy
The Reality: Metal roofing is one of the lightest roofing options available—typically 1-1.5 pounds per square foot versus 2-4 pounds for asphalt shingles, 9-12 for tile, and 8-10 for slate.
This light weight means:
- Metal can be installed over existing shingles in some cases (saving tear-off cost)
- No structural reinforcement needed for retrofit
- Less stress on your home's structure over time
The Truth About Metal Roofing
Metal roofing has real advantages: 50+ year lifespan, excellent wind resistance, fire safety, energy efficiency, and minimal maintenance. The myths that persist are based on outdated information or misunderstanding of proper installation. For a complete breakdown of metal roofing benefits, see our detailed guide. Options include standing seam for residential and exposed fastener for outbuildings—learn about the differences in our standing seam vs exposed fastener comparison.

"These myths come up in almost every metal roofing consultation. I understand where they originate—barns, pole buildings, and old metal roofs were often loud and basic. Modern residential metal roofing is a completely different product. Once homeowners understand that, many choose metal for its real advantages."
