The answer to 'signs of shingles damage' is that there are several common signs that your roof shingles may be damaged or deteriorating. These include curled, cracked, or missing shingles, as well as excessive granule loss. Shingles that are discolored, blistered, or have moss or algae growth are also indicators of potential issues.
It's important to regularly inspect your roof for these signs of damage, as they can lead to leaks, water intrusion, and further structural problems if left unaddressed. If you notice any concerning issues, it's best to have a professional roofing contractor take a closer look and provide an assessment.
