Q: Is a metal roof more expensive than a typical roof?
A: Metal roofing is a premium home product so it costs more than an asphalt shingle roof. However, a metal roof is comparable in price to cedar shake roofing or tile roofing. Also, it is less expensive than a slate roof. The good news is that a metal roof typically comes with a 30 to 50 year warranty. It adds to the resale value of your home and will help you save money on your energy bills.

Q: How can I know that a metal roof will match my home and roofing style in my neighborhood?
A: Today, metal roofing for residential structures is made to look exactly like roofing materials that are commonly used such as cedar shake, asphalt shingle, slate roofing, or cedar shake. However, it’s more durable and stronger. Metal roofing comes in a wide variety of colors, patterns, and styles, so you should be able to match the style of your home and neighborhood.

Q: Is lightning attracted to metal?
A: Lightning is attracted to the highest point. So a metal roof is not more likely to be hit by lightning than any other type of roof. However, metal roofs do dissipate an electrical charge, so if, by the rare chance your home is hit by lightning, a metal roof may help prevent your home from catching on fire.

Q: Can I walk on a metal roof?
A: Typically metal panel systems can support the load of an average individual walking on them. But you should take care to not cause damage to the roof because of abrasion or collapsing of the raised portion of the panel—as with any system.

Q: How much does metal roofing weigh?
A: Metal roof systems commonly weigh between one to three pounds per square foot. The metal gauge and profile of the panel determines the weight. Compared to other systems, metal roofing systems are considered a lightweight roof covering.

Q: How far can I span with metal roofing?
A: The profile, gauge, and width of the panel itself determines span capability. In order to determine if the panel meets the actual performance requirements for your project, consult individual load tables and test results.

Q: How much longer can I expect a new metal roof to last versus common roofing such as wood  shingle or asphalt?
A: A metal roof usually lasts two to three times longer than a regular roof. In other words, a metal roof can last 40 to 60 years or more. Typically, an asphalt roof lasts between 12 to 20 years, depending on pitch and climate. Asphalt roofs decompose but a metal roof will never decompose. Metal roofs retain their good looks and durability year after year after year.

Q: Is metal roofing noisier in bad weather than cedar shake, slate roofing, tile, or asphalt?
A: This is a common misconception about metal roofing. Metal roofs are often installed over a solid substrate. Furthermore, attic space and insulation provide even of a sound barrier. Research proves that metal is not any noisier than traditional roofing systems. In fact, you’ll hear more outside noise from windows and walls than your metal roof.

Q: How will a metal roof endure extreme weather?
A: A metal roof has the ability to withstand decades of abuse from high winds, hailstorms, heavy snow, wildfires, and other forms of extreme weather. Metal roofing has a wind rating of 120 mph—equal to an F2 tornado. It is also the roofing system of choice in locations of heavy snow because it protects the structural integrity of a roof. It eliminates ice damming at the eves so water won’t back up and create leakage into your home. Furthermore, it also adds protection if burning embers land on your roof. To top it off, metal roofing may even save you money on your homeowners insurance.
