Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

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

Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.

Remove the old paint on your metal roof, if any, remove rust and mold with a wire brush, and power wash the surface. Once the roof is clean and dry, start with a primer get painting.
