Strong Winds can cause shingles to blow off the roof. Leaks can result from the areas where shingles are missing. The adhesive seal that provides a water-shedding surface can also break, it is not easy to see the damage.
Potential signs of wind damage:
Missing shingles
Thin horizontal lines where granules have been worn off about 1-2 inches beneath the shingle above; this could indicate that the shingle seal was broken and the shingle was flapping in the wind rubbing against the shingle above it
Hail can damage your roof by leaving dents in your shingles, soffit, etc. It can bruise a shingle causing an indentation that may be hard to see but that can crack the shingle allowing water to leak over time.
Potential signs of hail damage:
Other hail damage around the house; dents on cars or other items on your house or in your yard
A distinct pattern of small round-shaped divots on the edges of the shingles
Indentations in the shingle where granules are missing
A large pile of granules at the end of your downspout; a small amount is normal, especially on new shingles
Winter can cause havoc on your roof. Leaks can be caused by an ice dam. Ice dams are formed by the continual thawing and refreezing which causes water to backup under shingles. Ice and water underlayment will prevent this leaking from occurring.
