1. Missing shingles, possibly blown off by wind, which allows water to seep into the house.
2. Damaged shingles, such as bare spots caused by premature granular loss, hail damage or tree limbs leaning on the roof.
3. Shingle deterioration, handfuls of granules found in gutters or the base of downspouts are tell tale signs that composition shingles are deteriorating. Also, note that with age shingles may split and crack creating another potential trouble spot.
4. Cracked flashing around any protrusions in the roof, typically plastic boots with rubber seals are used and can crack over time allowing water to easily penetrate the area.
5. Exposed fasteners (nails or staples), shingles should overlap each other covering the fasteners used to adhere them; any stray fasteners should be sealed.
6. Storm collars, usually around gas vent stacks and chimneys, be sure they are in position and properly sealed.

Homeowners should walk the entire surface of the roof looking for the above signs of potential damage. Ensure your safety while performing this inspection by using a sturdy ladder and some type of soft-soled shoe. It is also advisable to have another person nearby acting as a look out or spotter and ladder support. Carefully inspect all protrusions and how they are sealed. Tree limbs should never lean or rest on the roof surface. They will wear down the shingle and expose the roof decking to the elements, which can cause extensive damage to the interior of the house. Homeowners may also venture into the attic during rainstorms to see if there are any visible signs of leaking around pipes and vents. A homeowner should inspect their roof about once a year for tree limbs, obvious shingle damage, and cracked flashing. A professional should be called every 2-4 years for a more comprehensive inspection, less frequent for newer roofs, more frequently as the roof ages.
