Visible Damage

Cracked or Missing Shingles

One of the most obvious signs of roof damage is cracked or missing shingles. This can expose the underlying layers to water, leading to leaks and further damage. If you notice multiple shingles are compromised, it may be time to consider a replacement.

Asphalt shingles are coated with granules to protect them from the sun. If you find granules accumulating in your gutters, it’s a sign that the shingles are deteriorating and may need replacing.
