Not all storm damage to your roof is as obvious as torn shingles or a ripped off roof. Some subtle damages can lead to major problems if they aren't discovered promptly

1. Loose Nails

Extreme temperature fluctuations, pounding rain, and hail can all lead to popped nails. You may not even notice the damage at first, since the raised nail heads will be hidden by the shingle above the damage. Instead, the shingles may look a bit bumpy or uneven since the nails are lifting them slightly from beneath. If the nails aren't driven back in, shingles can tear off or moisture may leak in around the raised heads.

2. Shingle Compression

Shingle compression is caused by hail. Even small hailstones can lead to compression damage. It is one of the most difficult types of damages to spot because most of the damage occurs inside the shingle. Compression weakens the material so that shingles break down sooner than expected. Small leaks may also form through the weakened material. The subtle signs of compression are small indentations and shiny spots on the shingles.

3. Coating Loss

Asphalt shingles have a coating of gravel granules. These granules protect against sun damage and provide an additional waterproofing coating on the shingles. Heavy rain and hail, along with ice melt, can loosen and wash off this coating. Coating loss isn't immediately visible unless you know where to look. When loss is a problem, you will notice gravel buildup in gutters, at the base of downspouts, and along the ground under the eaves of the roof. There may also be smooth, shiny spots on the affected shingles. 

4. Vent Damage

Wind, hail, and heavy rain can damage rooftop vents. Damage can be minor, such as loosened or lost vent covers. More major damage is also possible, such as battered vent stacks or damage to the flashing and boots that seal the vent seam to the roof. You may notice that vents look dented or askew when surveying the roof from the ground. Flashing and boot damage may require a rooftop inspection to find. 

5. Eave Problems

Don't overlook the eaves and trim work along the edges of the roof. Many modern roofs feature metal or vinyl eaves and trim. Hail can dent or even crack the eaves, allowing water incursion into the attic. Hail can also scratch paint finishes on wood or metal eaves, which can allow moisture damage like rot and rust to occur. It's always best to check your eaves following any major storm.
