Impervious Homes: Revitalizing Historic Properties with Modern Roofing Technology
Challenge
In the heart of Charleston’s historic district stood a century-old Victorian home facing severe structural challenges. The owner, Dr. Eleanor Wright, approached Impervious Homes with concerns about extensive water damage threatening both the architectural integrity and the valuable interior of her beloved property. Years of coastal weather exposure had degraded the original slate roofing, creating multiple leakage points and compromising the underlying timber framework.
Assessment
The Impervious Homes team conducted a comprehensive evaluation of the property, identifying several critical issues:
- Deteriorated slate tiles with significant breakage and displacement
- Compromised flashing around chimney structures and dormers
- Water infiltration affecting 40% of the attic support structure
- Inadequate ventilation exacerbating moisture buildup
- Historical preservation requirements limiting material selection
Solution
Working closely with local historical preservation authorities, Impervious Homes developed a multifaceted approach:
- Custom-fabricated slate-alternative tiles matching the original aesthetic while offering superior durability
- Installation of a waterproof membrane system beneath the visible roofing layer
- Restoration of damaged timber framework using specialized preservation techniques
- Integration of hidden ventilation solutions preserving the historical appearance
- Copper flashing implementation enhancing both longevity and period authenticity
Implementation Process
The project required meticulous planning and execution over a 6-week period. Impervious Homes utilized specialized scaffolding systems to minimize impact on surrounding gardens while ensuring comprehensive access to all roof surfaces. The team documented each original component before removal, ensuring historically accurate replacement throughout the restoration process.
Results
Upon completion, the project delivered exceptional outcomes:
- 100% elimination of all water infiltration issues
- 50-year warranty on all installed materials
- Preservation of original architectural character
- 30% improvement in attic thermal efficiency
- Historical preservation board commendation for authentic restoration work
Dr. Wright reported complete satisfaction with both the process and results, noting that Impervious Homes had succeeded where previous contractors had failed in balancing modern performance with historical integrity.
