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 often should metal roofing be maintained?

• <div><p>Inspections should be conducted annually, and minor repairs should be made as needed.</p></div>

Q: Does a metal roof lower energy bills?

• <div><p>A metal roof can significantly reduce your energy bills by reflecting heat away from your home, so your cooling system doesn&rsquo;t need to work as hard to keep the inside cool. After installing a metal roof, you may see up to 40% lower energy costs, depending on how energy efficient your previous roof was and your area&rsquo;s average climate. </p></div>

Q: Do roofers use staples or nails?

• <div><p>Roofers most often use nails to fasten roofing shingles and other roofing materials. Nails have more holding power than staples and offer better weather resistance and longevity. However, it is possible to use staples instead of nails when installing a roof. Staples are less expensive, but not as high-quality.</p></div>

Q: Do aluminum roofs get hot?

• <div><p><a href="https://www.angi.com/articles/do-metal-roofs-make-your-house-hot.htm">Metal roofing gets hot</a> when it&rsquo;s exposed to direct sunlight, but aluminum is naturally reflective and can actually help keep your home cooler in hotter, sunnier climates. The solar reflectance of aluminum is significantly higher than that of asphalt shingles and clay tile, so a metal roof will reduce solar heat gain in your home.</p></div>

When we made contact, chimney sweeping went fine. However, we have called and emailed several times and Airstream Duct Cleaning simply does not respond. This is very frustrating and not good customer service. We will take our business elsewhere (if we can find another chimney sweep!).

Two person crew protected the surrounding area and cleaned the chimney as expected. The crew was friendly and inspected for any issues, none were noted. I would definitely recommend them and the price was great through Angie's List
