Metal Roof FAQ’s

Are metal roofs noisy?

This is one of the biggest misconceptions about residential metal roofing. People who’ve experienced barns or other structures where the metal roofing is visible from the interior can recall the “pinging” noise that rain makes when it hits the metal roof. In these applications, the metal roof is installed without a solid roof deck, so there is no dampening effect when something contacts the metal roof. In residential applications, metal roofing is installed on a solid plywood deck, just like shingles. When installed in this manner, metal roofing is no noisier than other roof materials.

Will a metal roof rust?

Union’s premium metal roofing products utilize high strength Metal Construction Association (MCA) certified steel that’s protected by an aluminum, zinc, and silicon anti-corrosion coating, commercially known as Galvalume®. The corrosion resistance of our steel roof is so outstanding, even our unpainted metal roof panels carry a 30 year limited warranty. We use this same high performance steel with our 40 Year and Lifetime series paint systems, giving you the highest level of corrosion resistant roofing you can get in the roofing industry. Beware of metal roofing that is not MCA certified as these metal roofs could be constructed with inferior steel and paint systems. Many metal roofing companies will advertise a paint warranty, but the underlying metal will not be warranted against corrosion. Be sure to ask about base metal warranties before you buy.

Does a metal roof attract lightning?

A metal roof has no greater chance of being hit by lightning than any other type of roof. Lightning typical targets the highest point in a given area, regardless of material. In the event that your roof is struck by lightning, a metal roof can actually help prevent damage by dissipating the electrical charge. Also, a metal roof is non-combustible.

Will I have to remove my existing roof?

Because metal roofing is so lightweight relative to its strength, metal roofs can usually be installed over existing roof materials. It’s very common for metal roofs to be installed directly on top of asphalt shingles. This saves on labor costs and disposal cost for stripping the old roof, not to mention reducing landfill waste. Local building codes and the condition of your current roof’s substructure will ultimately determine if you can install your metal roof in this manner.
