Chimney Repair questions, answered by experts

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.

Moss grows in dark areas of roofs, including in corners and gutters. If left alone, it can grow under roofing and cause permanent damage. Here’s how to remove moss from metal roofs: 

  • Soak the moss to soften it

  • Scrub it away with a soft-bristled brush, or pick it off with your hands (be sure to wear gloves)

  • Use a moss remover that’s compatible with metal roofing, following the manufacturer’s directions

  • Remove dead moss and rinse the roof thoroughly

  • Prevent future moss growth by trimming branches, cleaning gutters, and attaching zinc strips to moss-prone areas

Metal roofs often benefit from snow guards because the slick surface can lead to snow avalanches off of your roof, potentially damaging cars or personal property below and putting your family at risk of injury. Low-slope metal roofs may not require snow guards if your area doesn’t see heavy snow accumulation, but it’s a good idea to install them for security.

Metal roofs do not technically require a drip edge if the roof overhangs at least one inch, because the roof's slant will cause water to flow away from the structure. But a drip edge would be an added level of protection for a metal roof to help keep moisture issues at bay.

The average cost to repair hail-damaged roofing is about $4,250. However, depending on the extent of the damage and insurance policies, the cost can run from as low as $200 up to $32,500 or more. Repair costs also vary based on the type of roofing material, the size of the roof, the slope and other features of the roof, and your geographic location.
