You've got the weight of the things bolted to your roof. Is your roof new or less than new and needing replaced before the solar panels are paid for? Do you know a roofer who will touch solar panels during a re-roof? This doesn't even discuss the installer incompetence and the damage they'll do to your roof during install. Those panels are bolted to the roof and bolts cut through shingles and the sheathing underneath. All entry points for water.
Bolting solar panels to the roof is not viable in the long run, IMO. The damage and the advancement of tech means these things will be obsolete in the near term.

Your efficiency gains on single-junction monocrystalline cells are on the order of one percent per half decade. Damage to bolting to a roof? Not very much at all if you actually use the included sealing gaskets instead of bolting it straight in like most idiot installers, and the framing, done right, actually adds rigidity to your roof frame.
