My house is shaded by old growth trees. As a result, certain areas of my roof have little exposure to sunlight, (except winter, but the sun doesn't shine much in Ohio). As a result, I have problems with leaf accumulation and moss growing on the current asphalt roof. Is metal roofing more resistant to moss growth?

Generally speaking metal roofing is very resistant depending upon the finish and the roof slope. The best being bare Galvalume however in all cases the surface will still stain if the leaf debris remains on the roof and becomes wet. Once dirt grabs on the surface, then mold etc can get a foothold but will not cause any damage. Choose a smooth surfaced product and if painted it should be PVDF and if bare an AZ50 Galvalume. As added protection you could have a pure zinc strip attached at the ridge which sacrifices itself over time with each rain and the zinc will kill any mold or algea growth and keep the finish like new. It was developed for wood shingles on the NW coast however works great on all types of roofing even asphalt.

Have a galvinized or cooper moss control srip installed by a roofing the rain will run down your ridge over the strip and down your roof. the chemical in those strip prevents moss from growing

As advice I probably wouldn't use a copper strip, as it could react with the zinc coating on most metal roofs. (It acts as a battery & can create corrosion.
