5 Common Metal Roofing Myths Debunked

MCS Influencer John Sheridan addresses these five common myths related to metal roofing. 

1 – Rust. Everyone has seen an old rusty tin roof or corrugated barn or shed roof. Newer roofs are made of much higher tech components. Cutting edge coatings, highly durable base metals and advanced tools and installation techniques allow modern manufacturers and contractors to produce a high-quality, long-term roofing option/solution for home and business owners.

2 – Noise. Before there were modern codes and installation techniques, it was not unusual to see an old metal roof on open wood framing or in an open, uninsulated attic space. As attic spaces and insulation technology and requirements evolved, roof assemblies went from being just a thin metal skin to a layering of components to create a much more efficient building envelope. Solid sheathing, proper ventilation, insulation, high tech substrate components all combine to act as a buffer for the transfer of external noise to an interior living space. Metal roofs today are not significantly noisier than any other type of roof. 

3 – Lightning. Metal is conductive, but not necessarily attractive. The likelihood that a roof will be struck by lightning does not increase with the installation of a metal roof. Because the metal roof is conductive, it will actually help dissipate a lightning strike over the entire roof. 

4 – Temperature. Many people think metal is hotter in the summer and cooler in the winter. In the summer, metal reflects heat and does not absorb heat like a shingle roof. Interior climate control is part of a total system approach to the building envelope, so a well-constructed, well ventilated metal roof system will not adversely affect either heating or cooling of a living space. 

5 – Expensive. Metal roofs can last a very long time. The combination of a high-quality metal roofing system, a reputable manufacturer and a well-trained installer will provide a roof that will last significantly longer. When life cycle costing and performance are factored into the replacement or new installation of a roof, metal is highly competitive and affordable.
