The Lightning Myth
One of the most common concerns about metal roofing is the fear that it attracts lightning. In Pennsylvania, where summer storms can be intense, this worry is understandable. However, it’s a myth that needs clearing up.
Does Metal Attract Lightning?
No, metal roofs do not attract lightning. Lightning is attracted to the highest point in an area, not to any specific material. Trees, utility poles, or taller buildings are more likely to be struck than a metal-roofed home.
Why Metal Roofs Are Actually Safer
Metal roofs offer several safety advantages during storms. First, they are noncombustible, meaning they won’t catch fire if struck by lightning. Their durability helps them stand up to high winds, hail, and other storm conditions. Additionally, when properly grounded, a metal roof can safely disperse the energy from a lightning strike, reducing the risk of damage to your home.
Safety Measures for Metal Roofs
If you’re concerned, ensure your roof and home are properly grounded. Installing a lightning protection system can also help safeguard your structure—this applies to all roofing types, not just metal.
Common Myths Debunked
Many homeowners believe that metal roofs attract lightning or pose a higher danger during storms. In reality, lightning is drawn to height, not the material of the roof. Metal roofing is often safer because it’s fire-resistant and built to withstand severe weather. Understanding the science behind lightning strikes helps dispel these myths and makes it easier to choose a roofing material based on facts, not fear.
What Your Contractor Should Inspect
Your contractor should carefully evaluate whether the existing skylights are suitable to stay or need replacement during the roofing process. This includes assessing the age and warranty status of the skylight, checking for any signs of leaks, moisture, or internal fogging, and inspecting the frame and flashing for wear or corrosion. The skylight must also be evaluated for structural compatibility with the new roofing materials. A professional inspection of these elements ensures reliable performance and helps avoid future roof and skylight failures.
