Moss will hold water, and eventually rot the shingles.
(Added)
Moss puts down roots into the shingles, loosening the top granular protective layer. In addition, it will leach out the oils which give the shingle flexibility, drying and cracking them and leading to shingle loss and premature roof replacement. The additional water will freeze during the winter, lifting the shingles up, loosening the nails and allowing for shingle loss during winds, and for water penetration into the sheathing. Many a moldy attic has been traced to moss on the roof, which is why insurance companies are now starting to dictate it be removed safely (no pressure washing!) by a professional roof cleaning company.
