Even seemingly minor issues like leaky skylights or damaged roof vents can lead to significant water infiltration over time.

Plumbing Issues

Condensation and Humidity

Excessive humidity and condensation in attics or crawl spaces can promote moisture accumulation on ceilings, providing an ideal breeding ground for mold. Poor ventilation exacerbates this issue, trapping moisture and allowing mold spores to thrive.
