Most homeowners assume a leaking skylight means a defective product. In most cases, it means an installation shortcut.
π Proper skylight installation requires step flashing woven into the surrounding shingle courses and counter flashing sealed against the curb. When installers skip or rush this process, they create a path for water infiltration that is invisible until the roof is stressed by a heavy rain event.
Marios installs Velux skylights to manufacturer specification on every project. The flashing detail is not optional, and it is not the last thing we think about.
