Architectural Shingle Roof Replacement in Charleston (James Island), South Carolina

A single-family home in Charleston (James Island), South Carolina faced an aging 30+ year 3‑tab shingle roof with missing and wind‑damaged shingles, multiple patchwork repairs, no drip edge, and outdated whirlybird vents. During our neighborhood inspections, the family shared they were experiencing active leaks and couldn’t afford a replacement. After our free RoofServ Charleston inspection on December 1, 2025 revealed severe decking rot across roughly three‑quarters of the roof, we helped the homeowners file an insurance claim with The Hartford. An adjuster agreed with our assessment and, after a required repairability test, approved a full replacement. Installation was completed on December 19, 2025.

Project At-a-Glance

• Roof size: 26 squares (approximately 2,600 sq ft)
• Shingle system: GAF Timberline HDZ Class 3, Charcoal
• Insurer: The Hartford
• City: Charleston (James Island), South Carolina

Challenge: A failing 3-tab roof with leaks, code gaps, and unsafe decking

The original roof showed widespread age‑related failure—missing and brittle shingles, wind damage, and repairs of varying ages. It lacked drip edge, a local code item, and relied on whirlybird vents rather than ridge ventilation. On closer inspection, approximately 75% of the roof decking was rotted, creating a genuine fall‑through hazard and making spot repairs unrealistic.

Solution: Insurance-backed replacement, safety-first reconstruction, and a performance upgrade

We guided the homeowners through the insurance process and performed a repairability test that confirmed the roof could not be patched. Although the like‑kind approval was for a 3‑tab system, we self‑funded an upgrade to a more resilient architectural assembly better suited for Charleston’s wind conditions, while delivering modern ridge ventilation and code‑compliant edges.

• Removed the failing 3‑tab system and safely demolished compromised materials.
• Replaced 15 sheets of rotten plywood decking to restore a solid, nail‑worthy substrate.
• Installed two layers of synthetic underlayment for robust secondary weather protection.
• Applied GAF Ice & Water Shield in all valleys and on the rear 3/12 slope to mitigate water intrusion.
• Upgraded to GAF Timberline HDZ Class 3 architectural shingles (Charcoal) with GAF starter strip, hip & ridge caps, and corrosion‑resistant fasteners.
• Terminated outdated whirlybird vents and added continuous GAF ridge vent for balanced attic ventilation.
• Installed brand‑new drip edge to meet local code and improve water shedding.
• Performed meticulous magnetic cleanup and a final walkthrough.

Result: Leak-free protection, stronger wind performance, and peace of mind—delivered before the holidays

The home now has a modern roofing system designed for better wind resistance, water shedding, and attic airflow—key benefits for homes in Charleston (James Island), South Carolina. The upgraded assembly and new decking eliminated active leaks, reduced future repair risk, and improved overall durability.
