Why do copper roofs turn green?

• <div><p>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.</p></div>

Q: How long does it take to repair a roof?

• <div><p>How long it takes to repair a roof depends on damage, but in general you can expect roof repair to take a few hours to a few days. For example, replacing damaged shingles can take between one and four hours. Structural repairs, like fixing a sagging roof, can take up to four days. </p></div>

Q: How long do copper roof strips last?

• <div><p>Copper roof strips can last for 20 to 30 years or more if properly installed&mdash;in many cases, they may outlast your roof.
