Quick Answer
Metal roofing costs 2-3x more upfront but lasts 40-70 years, offers superior hurricane resistance (140+ mph winds), and reduces cooling costs by 20-30%. Asphalt shingles cost less initially, last 15-25 years in Florida, and provide adequate storm protection when properly installed with wind ratings of 110-130 mph.

Insurance Savings in Florida
Florida insurers offer significant discounts for impact-resistant roofing:
| Roof Type | Typical Insurance Discount |
|---|---|
| Standing seam metal | 25-35% |
| Metal shingles | 20-30% |
| Impact-resistant asphalt | 15-25% |

How Each Performs in Hurricanes
Metal roofing advantages:
- Interlocking panels resist uplift
- No individual pieces to blow off
- Standing seam has concealed fasteners
- Debris slides off smooth surface
- Less likely to become projectile
Asphalt shingle considerations:
- Individual shingles can lift and tear
- Proper nail pattern is critical
- Starter strips and edge metal essential
- Impact-resistant options perform well
- Easier to repair small sections
Post-Storm Damage Patterns
| Damage Type | Metal Roofs | Shingle Roofs |
|---|---|---|
| Wind damage | Rare panel lifting | Common shingle loss |
| Impact damage | Dents (cosmetic) | Cracks, punctures |
| Water intrusion | Unlikely if intact | Common with missing shingles |
| Debris damage | Surface scratches | Embedded debris, tears |
| Repair complexity | May need panel replacement | Individual shingle replacement |

FAQs
Is metal roofing too loud during Florida rainstorms?
Modern metal roofing with proper underlayment and attic insulation is not significantly louder than shingles during rain. The sound difference is minimal when installed correctly. Some homeowners actually enjoy the gentle sound of rain on metal.
Do metal roofs attract lightning?
No, metal roofs do not attract lightning. Lightning strikes the highest point in an area regardless of material. If lightning does strike a metal roof, the metal disperses the energy safely, and because metal is non-combustible, there’s no fire risk.
Will a metal roof rust in Florida’s humidity?
Quality metal roofing with proper coatings (Kynar 500, Galvalume, or similar) resists rust effectively. Aluminum is naturally rust-resistant and ideal for coastal areas. Steel roofing requires appropriate protective coatings but performs well when properly specified for Florida conditions.
Can I install a metal roof over existing shingles?
In many cases, yes. Installing metal over existing shingles can save removal costs and add insulation. However, this depends on local codes, roof condition, and structural capacity. A professional assessment is required to determine if your roof qualifies.
Do asphalt shingles perform well enough for Florida hurricanes?
Quality impact-resistant asphalt shingles rated for 110-130 mph winds provide good hurricane protection for most Florida storms. Proper installation with correct nail patterns, starter strips, and edge metal is critical. They’ve protected countless Florida homes through major hurricanes.
How much does a metal roof increase home value?
Studies suggest metal roofing can increase home value by 1-6% depending on the market. More importantly, metal roofs make homes more attractive to buyers concerned about hurricane protection and energy costs, potentially leading to faster sales.
