Not all hail damage can be seen on the surface of a roofing shingle. Sometimes the impact from a hailstone can cause shingles to split and can only be seen when you look at the backside of the roof shingles. It’s best to call a roofing contractor to assist in this type of inspection, as they can lift up, examine and re-seal shingles as needed. A professional roofing contractor will also assess other roofing components for damage, such as flashing, roof vents, skylights, gutters, and chimney caps or covers.
