There are other advantages to residential metal roofs. In addition to those already mentioned, they are quick to install and great at reflecting the heat from the sun. It’s a common misconception that because it’s hot on top it will be hot under the roof. But that heat is reflected away from the home. If it’s hotter on top, it’s cooler down below.
Most metal roofs are aluminum and/or steel, but copper and other alloys are also used. While the new designs can mimic the look of other traditional residential roofing materials, some popular styles retain a decidedly commercial look found by architects to give a home clean lines.
Surely its not all peaches and cream for metal roofs. They also have negatives which each homeowner must evaluate in relation to the advantages. At about $150-$600 per 100 square feet, it is expensive. But this expense can be recovered if the homeowner remains in the home for a long time, and it helps save on engineering and structural maintenance of the supporting structure. In a rain storm having a metal roof can be a little like living inside a drum. It can be much louder than other types of roofs. Using sound deadening insulation can help minimize the extra noise. Just like it can a car, hail can dent softer metal roofs such as copper and aluminum roofs. Some of them, however, are guaranteed against denting. When planning to walk on the roof for maintenance such as cleaning the gutters, keep in mind that a metal roof tends to be slippery when wet. Some metal finishes can chip and peel, although again they’re generally guaranteed for many years against such marring.
Don’t be worried about lightning strikes with metal roofs. They don’t attract lightning even though metal conducts electricity. They can also be grounded for extra protection.
When you wish upon a star, and residential metal roofing is where you are, look up at the shining light, and be happy your choice was right.
