Charlotte sits in USDA Hardiness Zone 7b with average summer humidity between 70% and 85%. This moisture-saturated air does not allow wood to dry completely between rain events. When afternoon thunderstorms dump two inches of rain in 30 minutes, gutters overflow and water cascades down fascia boards. The wood absorbs moisture, but the constant humidity prevents proper drying. Fungal spores, always present in our air, colonize the damp wood within 48 hours. This creates the brown rot you see when fascia boards start crumbling. Winter brings relief from humidity but introduces freeze-thaw cycles that crack paint and open new entry points for water. Charlotte's climate attacks fascia boards year-round from different angles.
Charlotte adopted the 2018 International Building Code in 2020, which includes specific requirements for roof edge flashing and water barriers. Many older homes were built before these standards existed. We follow current code requirements on all repairs, even when replacing boards on homes built in the 1960s or 1970s. This protects you during home sales and ensures your roof system performs as modern standards require. We have worked with local building inspectors for years and know exactly what they look for during inspections. Our familiarity with Charlotte's building department, common architectural styles in different neighborhoods, and local material suppliers means your project moves smoothly from start to finish.
