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

In many areas, chimney repair companies need to be licensed, but it depends on your state and local municipality. You can check with your local building department to see if companies need licenses, and then you can use Angi’s license lookup tool to confirm that the company you’re considering holds the proper license. It’s a good idea to confirm that the professional is fully insured, and you can ask about certification from organizations like the Chimney Safety Institute of America (CSIA). These certifications aren’t mandatory, but they help ensure a professional repair.

Metal roofs can rust, but steel is a material that holds up well to environmental factors, especially if it’s painted or galvanized. One of the main determining factors regarding rust is the environment the roof is in. Harsher environments with a lot of salt in the air will rust much more quickly than a steel or metal roof in a dry climate. Zinc-coated steel, called galvanized steel, is excellent at preventing rust from forming.

The lifespan of a roof patch depends on which materials you use and the severity of the damage. Temporary solutions like tarps or plastic sheets last a few weeks to a few months, while roofing tape or caulk may hold up for a year or two. Permanent patches using roofing cement, flashing, or replacement shingles can last several years as long as they're properly maintained. Regular inspections and touch-ups can extend the patch’s lifespan, but eventually, a full repair or replacement would be needed.
