Coverage & How Much You Need:

Fit and Compatibility:
Embed into wet roofing cement, flashing cement or bituminous coatings to match and protect repaired areas. Larger 80 lb bags and 5 gallon buckets are available elsewhere in the manufacturer's range; matching granules should be selected to the installed roof surface.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Gradation matters: finer #5 granules suit shingle touch-ups, while the coarser #3 gradation gives more texture on modified-bitumen and BUR surfacing. Always dry the granule into fresh coating while it is still tacky so it locks in rather than shedding. Choose the gray-and-white #4/5 blend where the existing surface has a mixed appearance.
Wear gloves and a dust mask when handling and broadcasting loose granules, and avoid application on hot, windy rooftops where material can scatter.
Order A-1 Grit kiln-dried granite granules in #3, #5 or the #4/5 gray-and-white blend for quality roof surfacing.
