Bellevue Premium Roofing provides professional skylights in Bellevue, WA for residential and commercial properties across the Eastside. Roughly half the skylight leaks we are called to between November and March are not leaks. They are condensation forming on the inside of cold glass and running down the shaft, and the homeowner has usually already paid somebody to seal flashing that was never the problem.
The diagnosis is quick if you watch the timing. Condensation shows up on cold, clear mornings after a still night, appears at the low corners of the glass and along the bottom of the frame, and is often worst when it is not raining at all. A real leak tracks the weather: it runs during sustained rain, especially wind-driven rain, and it stains the shaft or the ceiling outside the frame line.
The condensation fix is a house fix, not a roof fix. Get the bathroom and kitchen fans actually moving air outside, insulate the shaft walls properly, since a skylight shaft is a chimney of warm moist air pointed at the coldest glass in the building, and check whether the unit is a single-pane or an early double-glazed model with a failed seal. Replacing a nineties skylight with a modern insulated unit often ends the problem outright.
When it is a genuine leak, the usual causes are a small list. Deck-mounted units set on a shallow pitch, old step flashing that was never woven properly into the courses, a head with no cricket on a wide unit so debris and water pile against the upslope side, and sealant applied over a flashing failure by a previous repair.
Our default installation here is curb-mounted, with the manufacturer's flashing kit and self-adhered membrane wrapped over the curb before the metal goes on. A curb lifts the glass above the plane of the roof and above the debris line, which matters a great deal when fir needles are moving across the roof for two months every autumn. Deck-mounted units look sleeker and leak sooner under trees.
Then treat the skylight as part of the maintenance route, not as furniture. Moss establishes on the low-side flashing and in the head cricket faster than on the open field, because both stay shaded and hold debris. Two clearings a year, when the roof is being cleared anyway, is the difference between a skylight that lasts its full service life and one that gets blamed for a rotten shaft.
Our licensed and insured team brings the right materials and equipment to every job — zinc strip set under the first course of ridge cap, copper-bearing algae-resistant granules, self-adhered valley and penetration membrane, synthetic underlayment that stays flat when wet, kick-out diverter flashing at roof-to-wall junctions, step and counter-flashing let into a mortar reglet — and backs the work with a written workmanship warranty. We serve Bellevue and nearby communities including Mercer Island, Kirkland, Redmond, Issaquah.

Materials, equipment and how we do skylights
The difference between skylights that lasts and skylights that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with zinc strip set under the first course of ridge cap, copper-bearing algae-resistant granules, self-adhered valley and penetration membrane, synthetic underlayment that stays flat when wet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Bellevue job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Eastside means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Bellevue Chooses Bellevue Premium Roofing
- ✓We inspect the attic with a moisture meter before we walk the covering, because sheathing on the Eastside fails from the underside first and the roof surface is the last place it shows.
- ✓We will not pressure wash a shingle roof. Granule loss from a wand is permanent, it voids the surfacing warranty on every major brand, and we would rather lose the job than take five years off your roof.
- ✓Every replacement is a tear-off to sheathing with a per-sheet allowance quoted up front, so a soft deck under a north eave does not turn into a change order argument on day two.
- ✓Cool-season installs get hand-sealed edges, rakes and ridge cap, because an asphalt roof laid between October and April will not self-seal until spring and spends that winter loose.
The standards behind skylights
Quality here is not a matter of opinion — it is written down. The skylights work we do in Bellevue follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every skylights project in Bellevue gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
