Emergency roof repairs for active water intrusion follow a strict protocol: tarping with reinforced polyethylene sheeting secured to the roof deck, interior water extraction guidance, and temporary flashing at penetrations.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
