The Challenge
The home's aging 3-tab shingle roof had reached the end of its 20-year lifespan. Multiple shingles were missing or damaged, creating vulnerability to water intrusion. The homeowners experienced minor leaking during heavy storms and were concerned about potential water damage to their home's interior.
