-Shingle granules in the gutters and on the ground around the building – asphalt shingles are covered in a layer of surface granules that serve the purpose of protecting the shingle mat from the elements. Very severe weather can remove those granules from the surface, causing irreparable damage by exposing the shingle mat and requiring quick replacement;

-Damaged flashing – flashing consists of stripes of material, usually some type of synthetic material or metal, installed around roof openings and in roof valleys to strengthen the roof where its continuity is broken.
