Metal Roofing Myths

Metal-Roofing-Myths-Accel-Residential.jpg1. A metal roof increases the likelihood of a lightning strike!
  • The answer to this question is “absolutely not”. 
  • Lightning typically strikes the highest object in an area. 
  • That’s why it often strikes trees, power poles, antennas, and towers. 
  • Since metal roofing isn’t combustible or flammable, it’s a low risk and desirable roofing option where severe weather is concerned -- especially for lightning.
2. Metal roofs are loud!
  • When installed with solid sheathing, a metal roof on your home will actually silence noise from rain, hail and bad weather better than other roofing materials.
  • The human ear can not differentiate decibels unless there is an eight decibel difference.
  • Asphalt Shingle : 46 decibels
  • Pan Tile (TechoTile) : 31 decibels
  • Corrugated : 49 decibels
  • Scan Roof : 52 decibels
3. My metal roof will rust!
  • Steel metal roofing has a “metallic coating” made of either zinc or a combination of zinc and aluminum. 
  • This metallic coating prevents rust from forming and is bonded to the steel at the factory. 
  • Paint is then applied over the metallic coating to provide the long-lasting color.
  • For coastal or wet geographies, always specify an aluminum substrate which will outperform steel on those projects.
4. Hail will dent my metal roof!
  • A typical hail storm will not dent your metal roof, but it will destroy your shingles.  
  • Some metal roof systems today have a 120-mph wind rating, meaning your metal roof is also safe from wind gusts that can accompany hail storms.
5. A metal roof will make your house colder in the winter and hotter in the summer!
  • A metal roof has no effect on the temperature of the typical vented attic in winter.
  • It’s the insulation under (or on top of) the floor of your attic that keeps you warm in the winter.  
  • Metal roofing is also highly reflective so it can help your AC work more efficiently and keep your home cooler in the summer.
  • Cost saving.
