Skylight leaks in Sunnyvale

Skylights leak at the flashing kit or the perimeter seal far more often than through the glass itself. The unit sits proud of the roof plane and interrupts the water path, so everything depends on how the flashing was stepped into the surrounding courses. Water showing at the corners of the opening inside is the classic sign. Condensation on the inside of the pane is a different problem entirely — that is ventilation, not a leak, and sealing the outside will not touch it.

What the job involves

  • Assessment of the perimeter seal and any sealant previously applied
  • Check of the glazing unit seal where condensation is suspected
  • Reflashing rather than resealing where the kit has failed
  • Ventilation check if the moisture is condensation rather than ingress

Signs you need it

  • Drips at the corners of the skylight opening
  • Staining on the plasterboard reveal around the window
  • Moisture between the panes of the glazing unit

Why roofs fail in Sunnyvale and Dallas County

Sunnyvale sits in one of the most active hail corridors in the country, and hail is the roof killer here in a way that is easy to underestimate. The stone rarely punches through a shingle. It bruises the asphalt mat beneath the granule surface, leaving a soft spot that sheds water for another season or two and then fails — which is why a leak in Dallas County so often traces back to a storm the owner had stopped thinking about. Insurers know the pattern and scrutinise the gap between storm date and claim, so the roofs that get paid for are the ones that were documented when the hail fell rather than when the ceiling stained. Wind arrives with the same systems and does the quieter damage: lifting tabs, breaking the seal strip underneath, and leaving a roof that looks untouched from the driveway.

Sunnyvale has a population of about 9,008, and the housing stock here sets the pattern for what fails first on a roof.

Questions about skylight leaks in Sunnyvale

Is condensation on my skylight a leak?

No. Moisture on the room-side face of the glass is warm damp air meeting a cold surface, and it is a ventilation problem. Moisture trapped between the panes means the sealed unit has failed and the glazing needs replacing. Neither is fixed by working on the roof.

Can an old skylight be reflashed, or does it need replacing?

If the unit itself is sound it can be reflashed, which is far cheaper. Replacement makes sense when the frame has rotted, the seal between panes has gone, or the unit is old enough that matching flashing is no longer available.
