Challenge: Restoring a Hail-Damaged Roof with Active Leaks

The Johns Creek home had sustained heavy hail damage that compromised the shingles and sections of the gutter system. The roof had a single layer of architectural shingles that required full tear-off, and interior leaks had already begun in the living room ceiling. Added complexity included steep slopes on portions of the roof and compliance with HOA requirements inside a gated community.

• Performed a full tear-off of the existing 84-square roof down to the decking for a clean substrate.
• Replaced five damaged sheets of roof decking to restore structural integrity.
• Installed synthetic felt underlayment to add a superior secondary water barrier.
• Upgraded ventilation from box vents and power fans to a continuous ridge vent system for balanced attic airflow.
• Installed GAF Timberline HDZ shingles in Weathered Wood for strength, longevity, and curb appeal.
• Replaced pipe boots, added new black drip edge, and refreshed chimney/step flashing to prevent future leaks.
• Protected the property with comprehensive landscape tarping and managed safe material and dumpster placement.
