Steel roofs are noisier than slate or asphalt tiles but less noisy than aluminum and other types of metal roofing. While some find the sound pleasant, others may want a quieter roof. To reduce noise in your living area, you can install thicker underlayment or add insulation or even acoustic tiles between the roof and the house.

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.

Copper roof strips offer better coverage and more damage protection than zinc roof strips. Although both deter moss and algae growth, copper also offers UV protection. Zinc strips require more strips than copper to cover the roof’s surface area, which means more holes in your roof. Copper strips are also more flexible and last longer than zinc strips.

Like any housing material, metal roofs have a unique list of pros and cons. On the cons side, metal roofs can suffer from expansion and contraction, which requires more attention to proper installation than for other roofing types. Also, the higher cost of metal roof installations is a barrier to some homeowners on a budget.
