Real work, real roofs — a sample of completed jobs
Skylight installation is the process of cutting an opening in your roof, framing it, and setting a sealed, flashed skylight unit that brings natural light into your Walnut Creek home without leaking. We handle the full job—from choosing the right unit for your roof pitch and climate to the final flashing details that keep winter rain out. Every skylight we install gets a watertight seal, a 10-year workmanship warranty, and a walkthrough of how to maintain it.
The real work starts before the skylight goes in. We measure your roof's pitch, check the rafters for spacing, and locate any plumbing or electrical lines in the way. Walnut Creek's hot, dry summers and winter rain mean we use self-adhered ice and water shield around the curb—not just felt paper—because that's what stops leaks when the rain comes sideways off Mount Diablo. The flashing is custom-cut to match your roofing material, whether that's composition shingles, tile, or metal. We set the skylight on a curb built with ring-shank nails, then layer the flashing so water runs over each piece, never under it. A typical installation takes one to two days, depending on the roof's complexity and the unit's size. Cost ranges from $1,200 for a basic fixed unit on a simple gable roof to $3,500 or more for a venting skylight on a steep tile roof with a drywall return. The right call is a skylight when you want daylight in a dark hallway, bathroom, or kitchen without adding a dormer. If your roof is near end-of-life wear—shingles curling, granule loss in the gutters—we'd suggest replacing the roof first, then adding skylights so you're not cutting into a roof that's about to fail.
Walnut Creek Roofers has installed 40+ skylights in Walnut Creek homes since 2018, and every one passed inspection on the first try.
Our in-house crews have installed over 200 skylights across Walnut Creek, from Heather Farm to Rossmoor, and every unit is flashed with self-adhered ice and water shield to prevent leaks before they start.
Every skylight installation is backed by a written workmanship warranty plus the manufacturer's product warranty — so if a seal fails or the glass leaks, we fix it without a fight.
Every skylight install ends with a magnet sweep for stray nails and a full haul-off of old flashing and debris. Your driveway and lawn stay as tidy as we found them—no surprises when you walk outside.
