Metal roofs are very safe, and will not spark and ignite into flames during a wildfire or lightning strike.
Reflect solar radiant heat, which can reduce cooling costs by 10-25%.
Depending on the material used, metal roofs are 25-95% recycled content. They are also 100% recyclable when you no longer need them.
Can be as much as two or three times more expensive than other roofing materials.
Metal roofs can be noisy, especially during a heavy rain or hailstorm.
Metal roofing materials that are attached as large panels tend to expand and contract. If they are not properly installed with fasteners that allow the metal to “breathe,” the panels may loosen.
Metal roofs can be inconsistent and difficult to color match. If a repair is required or a home extension is added years later, it may be difficult to find an exact match to the existing metal.
If water accumulates anywhere on the roof because of poor-quality installation or repair, it can eventually cause serious damage.
