After inspecting your roof Melven General Contracting found significant damage to your roof.  The damage found is consistent with a loss due to hail.  Three out of the four slopes have 10+ hits per square.  The final slope has 8+ hits.

In my professional opinion the roof needs to be replaced.  Ignoring the damage may result in further damage to your property.  There is a leak in the garage that may have been caused by hail.  The sheet rock is wet and needs to be repaired.
