VELUX Skylight Installation

This roof system had several installation and aging issues that ultimately led to major failure and active leaking. One of the main problems was the skylight curb, which is the raised structure the skylight sits on. The existing curb was built too low, making it vulnerable during heavy rain and snow events. Over time, this caused repeated minor water intrusion that eventually contributed to more serious leaks. The edge metal system was also outdated and failing. The original metal was approximately 100 years old and used an older single-piece detail fastened with exposed nails driven through the metal. As the system aged, the metal loosened and shifted, and the exposed fasteners created additional points for water penetration. Another issue was the roofing material itself. The roof had reached the point where replacement was necessary, and the assembly needed to be upgraded to a more reliable low-slope roofing system. The chimney detail also required correction. Proper flashing is critical where the roof meets the chimney, and the existing setup did not provide the level of protection needed for long-term watertight performance.

The completed system provides a far more durable and watertight low-slope roof assembly. By correcting the skylight curb condition, replacing the failing perimeter metal, upgrading to a new TPO membrane, and improving the chimney flashing detail, this project resolved the major leak points and delivered a much longer-lasting roofing system. The modern three-part copper edge system offers superior protection compared to the older nail-fastened design, while the VELUX skylight brings natural light into the kitchen space with energy-efficient glazing and automated blinds for convenience.
