Roof damage to asphalt shingles can come in a variety of manners. The photo uploaded shows a roof shingle that has completely detached. I would classify this a functional damage. This type of functional damage would likely have been caused by wind.

This is a picture of a roof with architectural asphalt shingles. The roof overall looked to be in good condition. The shingles are approximately 15 years old and are aging as expected. This picture is from the eave to show there is a rise approximately 3 feet in diameter in the roof which could slow the flow of water and result in water intrusion. Also noted that the vent stack is only extending through the roof 3 1/2 inches. Recommend a licensed professional to further evaluate.

Moisture comes in liquid, solid, and vapor forms and can be damaging to shingle roofs. Liquid which is from rain can wash away granules, get under shingles through damage or improper flashing and cause damage to the sheathing. Solid moisture or ice can cause ice dams which will back melted water under the roof covering. Forms of vapor or gas come from inside the home via washing clothes, bathing, cooking etc. The vapor can cause damage if it is not vented properly.
This picture shows an architectural style asphalt shingle roof. The lower roof has a darkened area in the middle lower portion. There are no overhanging trees and no debris. It is not soft or wet so it is likely a lack of maintenance versus moisture issues.
