Skylight Installation in Walnut Creek, CA

Name: Walnut Creek Roofers
Telephone: 9255031377
Price range: $$

Walnut Creek Roofers installs skylights on a framed curb that ties into the roof deck, and most of the leaks we chase begin at the flashing. Hot, dry summers and strong afternoon winds here dry out old sealant and lift counter-flashing off the curb. Call 9255031377 for a free roof estimate and a written quote.

A skylight installation starts on the rooftop, not in the ceiling. We cut the opening from above, frame a curb between the rafters, then sheathe it and flash it before the unit comes out of the box.

Mid-century modern homes from the 1950s and 1960s often have shallow pitch, so ponding water at the curb matters more than wind uplift. Contemporary homes built in the 1990s and 2000s leave enough attic clearance to work around the truss and joist layout.

Cost comes down to unit size, glazing, and how much shingle field has to come up. A fixed skylight runs less than a vented skylight with solar-powered blinds, and a Solatube sun tunnel costs least of all.

Spanish and Mediterranean revival homes hide the curb behind tile or slate, which takes longer to reset and match. The building code here sets a minimum curb height and calls for ice-and-water shield at the opening, so we build to that before we quote.

What's Included

A full roof inspection from the attic side and the rooftop, with a written roof estimate that itemizes the unit, the flashing kit, and the labor.

Layout of the curb between rafters or trusses, sized to the rough opening the manufacturer specifies.

Framing and new sheathing, using plywood or OSB matched to the thickness of the existing decking.

New underlayment and ice-and-water shield wrapped up the curb, plus a vapor barrier inside the shaft.

Step flashing and counter-flashing tied into the field course, with a fresh drip edge and sealant at the rake and eave.

Interior finish: a trimmed shaft, patched drywall, and insulation packed back around the opening.

A water test on the finished curb, and a walkthrough of what the roof inspection found.

Signs You Need Skylight Installation

Brown water stains on the ceiling, or a ring of paint that flakes near the shaft after winter storms.

Condensation trapped between the panes, which usually means the factory sealant in the glazing unit has failed.

Daylight or a draft you can feel around the interior frame, a sign the counter-flashing has pulled away from the curb.

Old caulk and sealant around the curb that has cracked, peeled, or gone chalky through the summer heat.

Granule loss or curled shingle courses upwind of the opening, where wind-driven rain wicks under the flashing.

Soft wood at the curb when you press on it, which means rot has moved through the sheathing and into the rafter tails.

Our Skylight Installation Process

Step 1: Roof inspection and a written roof estimate. We check the attic for moisture content, measure the rafter spacing, and confirm what the building code requires for curb height and insulation here.

Step 2: Layout and cutting. We mark the opening from inside and outside, cut the shingle and sheathing from above, then trim any joist or purlin that blocks the unit.

Step 3: Curb framing. We sister new framing to the rafters, add a ridge beam only when the span demands it, and sheathe the curb square so the unit sits level.

Step 4: Waterproofing. We run the underlayment and ice-and-water shield up the curb, set step flashing into each course, then counter-flash the head and the sides.

Step 5: Setting the unit. We bed the skylight in sealant, anchor it with the fasteners the maker calls for, and connect any solar-powered blinds before we close the interior.

Step 6: Water test and cleanup. We flood the curb with a hose, check the attic for seep, then clear the debris into the dumpster and reset the surrounding field course.
