The answer to 'roof installation damage' is that there are several common causes, including improper installation, poor workmanship, and damage during the installation process. Symptoms can include leaks, missing or damaged shingles, and structural issues. The best solution depends on the extent of the damage, but in many cases, it's best to call a professional roofing contractor to inspect the roof and make necessary repairs.
Attempting DIY roof repairs can be risky and may cause further damage if not done properly. Homeowners should only consider minor tasks like replacing a few missing shingles themselves. For more significant issues, it's always recommended to hire a licensed and experienced roofer who can properly diagnose the problem and provide a long-term solution.
