After a hail storm in Louisiana, there are several specific signs of roof damage that homeowners should look for during a post-storm assessment. Key indicators of hail impact include visible dents on metal flashing and drip edges. You should also look for displaced or lifted shingles that may have left the underlayment exposed to wind-driven rain, as well as small, circular marks or pockmarks on the shingles where protective granules have been knocked off. Additionally, check for debris impact punctures, broken sealant strips, and dents or dislocation affecting vents, turbines, and chimney caps.
