Should skylight flashing be consistent with both headwall and sidewall flashing?

The correct answer is that skylight flashing should indeed be consistent with both headwall and sidewall flashing. This consistency is crucial for ensuring that the roof system effectively prevents water infiltration. When skylight flashing aligns properly with the headwall and sidewall flashing, it creates a continuous barrier that directs water away from the skylight and the adjoining roofing materials.

Improper or inconsistent flashing can lead to water pooling or directing water towards vulnerable areas of the roof, resulting in leaks and potential damage to the interior spaces. The integrity of the roofing system relies on proper installation techniques, and by matching the flashing types, roofing professionals can guarantee that water is adequately managed, enhancing the overall durability of the structure. This principle applies to all installations, regardless of whether they are new or existing structures, emphasizing that best practices in roofing should always be upheld to protect against moisture-related issues.
