Chimney Sweep questions, answered by experts

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

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Regular cleaning, inspecting for peeling or rust, and reapplying coatings every 8-12 years helps maintain durability.

It is not advisable to use salt on your roof to prevent or remove ice dams. It’s not only mostly ineffective but can also cause serious damage to your roof itself. Salt can rust metal, damage masonry, pit shingles, and cause runoff that’s damaging to plants and animals. 

Inspections should be conducted annually, and minor repairs should be made as needed.
