Zinc roofs can last over 100 years under ideal conditions. While metal roofs last a long time, only copper roofing is comparable to zinc's longevity. Zinc roofing develops a patina over time, turning from dark shades to lighter ones. The material, or at least the patina coating, is somewhat self-healing by filling in small gaps and scratches on its own.  

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

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.

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.
