San Bernardino Window Replacement is San Bernardino County's trusted specialist for skylight installation in San Bernardino, CA, specializing in replacing crazed acrylic domes, flashing curb-mounted units into clay tile and setting deck-mounted glass on shingle roofs. We offer venting roof windows and tubular daylight devices.
Our team provides Low-E glass skylights with a low SHGC, delivering daylight to a dark hallway or kitchen without the heat of a valley afternoon, often alongside whole-house window and door work, for both residential and commercial projects. The installer who measures the roof opening and its curb is the same person who sets the new unit, and we water test the head and side flashing before any ceiling trim goes back up.
From a new curb flashed into a barrel tile roof to a full set of matched skylights across a home or an apartment building, our team handles every detail. Serving San Bernardino with Highgrove, Redlands and Upland close by, we plan roof openings around the weather and the roofing material you already have.
Why San Bernardino Window Replacement
The installer who measures your openings is the one who sets the new windows, from the first visit to the final walk.
Skylight replacement in San Bernardino usually starts with a plastic dome that has gone cloudy, crazed or brittle, or with a ceiling stain under it. Acrylic is the most common plastic for dome skylights, and it has known weak points: it scratches more easily than glass, many cleaning chemicals attack it, and it behaves in a brittle way under impact. It also expands and contracts more than glass, which works its seals and fasteners every hot day and cool night.
A failing dome is rarely the only problem. Flashing is what keeps water out around the opening, so a new dome set on tired old flashing can leak exactly as before. We replace the unit and its flashing as one job.
Flashing is the part that keeps a skylight dry, and it is the part most likely to be done wrong. Flashing is essential around skylights and roof windows, and installed badly it directs water into the building instead of away from it. Step flashing laps in overlapping pieces like stairs so water runs down and off, and counter flashing caps a base flashing.
A deck-mounted skylight is fastened directly to the roof deck and sits low. A curb-mounted skylight sits on a built-up frame, usually two-by-fours, and is more common on low-slope roofs. Tile and shingle roofs can take either type; metal roofs take deck-mounted units only. Roof type and slope decide which one we quote.
Tile roofs change the install. Spanish style houses carry low-pitched clay tile, and terracotta roofs have been standard on Southern California tracts since the 1970s. Tiles around the opening are lifted and set aside, the flashing kit for a tile roof goes in over the underlayment, and the tiles are cut and relaid to the new curb. Broken or brittle tiles are replaced, which is why a tile job is quoted with spare tile in mind.
On asphalt shingle roofs, step flashing interweaves with the shingle courses up each side of the skylight. Shingles are lifted, not torn off, wherever they can be reused.
Manufacturer installation systems pair the flashing with a gasket or deck seal and an adhesive underlayment. The flashing kit is usually sold separately from the skylight, so we list it as its own line rather than assuming it came in the box.
Dissimilar metals corrode each other: copper and lead in contact with or above aluminum, zinc or coated steel cause early corrosion. Flashing and fasteners are matched to the skylight frame for that reason.
A skylight in valley sun needs Low-E glass and a low SHGC, and sometimes a shade as well. San Bernardino summers have hit 118 degrees, and a skylight faces the sky all afternoon, so it gains more heat than a wall window of the same size. Hot climates put a low SHGC first; cold climates put a low U-factor first. Here, the SHGC leads.
California's energy code, Title 24 Part 6, is updated every three years, and the 2025 standards take effect on January 1, 2026. Where a permit applies, the skylight's label values are checked against the code in force when the work is permitted.
Fixed, venting and tubular skylights solve different problems, so the room decides the type.
A fixed skylight does not open, so it brings in light but no ventilation. It suits living rooms, stairwells and long hallways where the goal is daylight alone.
A venting unit has a hinged sash that opens. Within reach of the occupants it is called a roof window. In a kitchen or bathroom it lets hot, steamy air out at the ceiling, where it collects.
A small roof dome, around 10 inches across on homes and up to 22 inches on commercial buildings, feeds light down a reflective tube to a diffuser in the ceiling. Tubes suit inner rooms, closets, laundries and bathrooms where a full skylight shaft will not fit, and they need no electrical work. Short, straight runs deliver the most light, so we plot the tube path in the attic before quoting.
Skylights are worth doing in a batch. Replacing every aging dome on a house at once means one roof crew visit, one set of lifted tiles and one permit, and the units match.
For a multi-unit or commercial job, send the roof plan or a unit count and we return a written scope by building.
Skylight installation and replacement in San Bernardino is typically estimated at roughly $1,500 to $6,000 per skylight, with the roof type, the unit type and the ceiling work moving the number most. A deck-mounted fixed unit on shingles in an existing opening sits near the low end; a new venting skylight cut into a clay tile roof with a fresh drywall shaft sits near the top.
These figures are estimates for the San Bernardino area and are subject to change with roofing and product costs. The final price comes from the written quote we prepare after looking at your roof and ceiling in person.
The process
Four steps, and nothing is ordered until you have signed off on the written quote.
We look at every opening with you, check the frames, the sills and the stucco around them, and measure each one for the unit that will go in it.
Frame material, glass package, label values, install method and the order date arrive in writing. For a community or a commercial building the work is split into phases, so every resident or tenant knows their day.
Old units come out, openings are checked for water damage, and each new window is set, flashed and sealed, with a water test at the sill before trim goes back.
We open and lock every window and door with you before calling it finished, and adjust anything you flag.

Questions
If the dome is crazed, cracked or cloudy, replace it. Because the flashing is what keeps water out around the opening, replacing the unit and its flashing together is the repair that deals with a leak at its source.
Most skylight jobs are estimated at roughly $1,500 to $6,000 per skylight, depending on roof type, unit type and ceiling work. Treat those numbers as estimates that may change; the written quote after a roof visit sets the final price.
Yes. Tile roofs take either deck-mounted or curb-mounted skylights. The tiles around the opening are lifted, the tile flashing goes in, and the tiles are cut and relaid to the new unit, with spare tile allowed for breakage.
Not with the right glass. A sealed two-pane glass skylight with a Low-E coating and a low SHGC keeps most of the sun's heat out, and a shade handles the hottest afternoons.
A skylight is a full glazed opening with a shaft to the ceiling. A tubular daylight device is a small roof dome feeding a reflective tube to a ceiling diffuser, which fits rooms and spaces a skylight shaft cannot reach.
Yes. Venting skylights have a hinged sash, and they work well in kitchens and bathrooms where hot air collects at the ceiling. Fixed skylights bring light only.
A new roof opening generally involves framing and roofing work that may need a permit, and replacements can too. We check the requirement for your address and list any permit on the quote.
Yes. We scope it by building, phase the roof work with notice to residents, and send a written schedule and unit count for the board or manager to approve.
Homeowners get a free measure at the house. Boards, managers and contractors can send plans or an opening count for a bid.
Calls only, we do not receive text messages.
