Skylight leaks in La Puente
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
- Inspection of the flashing kit, head, sill and side step flashing
- Assessment of the perimeter seal and any sealant previously applied
- 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 La Puente and Los Angeles County
La Puente has a roofing climate most of the country would not recognise: months of relentless UV with almost no rain, then the year's water arriving in a handful of concentrated winter storms. That pattern is harder on a roof than steady weather. Sun bakes the oils out of asphalt and hardens every rubber and sealant component until it cracks, and the failures sit there unnoticed through the dry months because nothing is testing them. Then the first real atmospheric river arrives and finds all of them at once, which is why leak calls across Los Angeles County cluster into a few weeks each winter. Low-slope and flat sections are the particular weak point here — they are everywhere in the local housing stock, they pond rather than shed, and their membranes are exactly what the UV has been degrading.
La Puente has a population of about 38,062, and the housing stock here sets the pattern for what fails first on a roof.
Questions about skylight leaks in La Puente
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.
