Replace a skylight when repair no longer makes sense: the glass has fogged, the dome has crazed, the frame has moved or the same leak keeps returning. This page covers swapping and adding units. If yours only needs sealing or flashing work, start with skylight repair, and see our wider skylights and roof ventilation page for the full picture.
What does skylight replacement in Los Angeles include?
A replacement swaps the whole unit, not just the glass, and rebuilds the flashing so the new skylight sheds water. Scope is written down before work starts, and anything we find under the old unit is a separate line you approve or decline:
- Removing the old skylight, curb or frame, and its flashing
- Opening the roofing around the unit to see the underlayment and deck
- Replacing soft decking or a rotted curb, explained first
- Setting the new unit with flashing woven into the surrounding roofing
- Re-sealing the light well edge where the shaft meets the roof
- Photographing the opening before and after
A custom-size unit may need to be ordered, which sets the schedule. Interior drywall and paint in the light well are usually separate work.
When is it time to replace an old skylight?
Three things say replace. The first is fogging between panes, because the seal cannot be restored. The second is yellowed or crazed plastic, since the dome will keep cracking. The third is a skylight that has leaked more than once after repair, which means the flashing and frame are worn together.
Age matters too. Skylight seals and gaskets often last longer than a typical shingle roof, but not by much, and rated lifespans vary by maker, so the manufacturer's rated life governs. If your roof is due, treat the skylights as part of the same decision.
Which skylight options matter when you replace one?
Most of the choices fall into four groups.
| Type | Best fit | Trade-off |
|---|---|---|
| Fixed, deck-mounted | Pitched shingle and tile roofs | Light only, no ventilation |
| Venting (manual or electric) | Kitchens, baths and stairwells that need airflow | More parts, higher price |
| Curb-mounted | Flat and low-slope roofs | Needs a built curb and good flashing |
| Tubular daylight device | Hallways, closets, small baths | Less light, no view |
Glazing matters in Los Angeles because of heat. Low heat-gain glass and laminated or tempered inner panes are common choices, and a shaded or north-facing spot cuts summer gain further. California's Energy Code generally expects skylights to carry a performance rating label, so compare those numbers instead of the look of the glass.
How skylight replacement works, step by step
- Measure and photograph. We check the opening, the curb, the light well and the roofing, so the new unit matches or the framing change is planned.
- Protect the house. Interior surfaces under the opening get covered before anything comes out.
- Remove the old unit and flashing. Roofing around the opening is opened back so we can see the underlayment and decking.
- Repair what is under it. Soft decking or a rotted curb is replaced and explained first, before new parts go on.
- Set the new skylight. The unit goes in, with new flashing woven into the roofing around it and a cricket on the uphill side of wide units.
- Close in and check. The area is sealed and checked, and where conditions allow, water goes on the roof to see how it sheds.
What affects skylight replacement cost in Los Angeles?
Opening size and roof type move the price more than anything else. A swap in the same opening is the cheapest case. Moving or enlarging an opening adds framing and interior shaft work. Tile roofs cost more to open and reset than shingle, and steep or two-story roofs cost more to reach. Glazing, venting and electric operators all add to the unit price, and a custom size takes longer to order than a stock one, and interior finish work is often a separate scope, so ask who does the drywall and paint.
Our prices come in writing after we see the job. Our guide to skylight replacement cost shows what a good estimate itemizes.
Adding a skylight where there was none
New skylights mean cutting through the roof deck, framing a header between rafters and flashing the opening. Where the roof is built with trusses, the opening has to sit between them, because trusses cannot be cut without an engineer. A solar tube avoids most of that, and it is usually the better answer for a narrow attic.
Think about where the light will fall. A skylight over a kitchen island works differently from one over a staircase, and one on a west-facing slope adds more afternoon heat than one facing north. If you are already re-roofing, bring it up before the estimate. One Van Nuys customer describes a job of seven skylights installed on a two-story home. Roofing and ventilation choices around them are covered on our attic ventilation and attic insulation pages.
Permits, Title 24 and HOA review for new skylights
A same-size swap and a new opening are not treated the same way. A new or enlarged opening changes the roof framing and can bring permit and energy-code review. The City of Los Angeles building department (LADBS) or your local agency decides what applies, and the contract should name who pulls the permit.
Some neighborhoods add their own review. San Marino sends estate-scale Period Revival homes through a design review. Many Calabasas tracts are HOA-governed and specify concrete tile. Check approval rules before choosing a visible unit. Near the coast, Santa Monica and Marina del Rey have marine and salt-laden air that attack metal flashing and fasteners, so ask what the flashing is made of and how it is protected.
Why Clear Shield for skylight replacement in Los Angeles
Reviewers in Van Nuys mention skylight work directly. One customer describes three skylights replaced even with light showers that morning. Another job named in reviews was seven skylights installed on a two-story home. Others describe a full water test after a repair and photos or drone images sent as the work went on. Get your skylight warranty terms in writing before work starts, and ask what the maker's coverage actually covers.
What Van Nuys customers say about skylight work
“I recently had my old shingle roof replaced with a new CertainTeed Pro line roofing system, and I am very happy with the results.”
“We were deciding between a standing seam metal roof and asphalt shingles, and frederick was a great guide who helped us understand the pros and cons so we could make the best choice for our home and budget.”
“They also took care of the permit process, which made everything much easier for me.”

Skylight Replacement: common questions
How much does skylight replacement cost in Los Angeles?
It depends on size, roof type, how many stories up the roof sits, the glazing and whether the opening or curb changes. A like-for-like swap costs less than a new opening with framing. We do not quote ballpark numbers in the abstract. You get a written price after we see the roof, with the skylight, flashing and any carpentry listed as separate lines.
Can several skylights be replaced in one day?
Often, if the weather holds and the openings stay the same size. Each unit is out of the roof for a short window and is covered or closed in before the next one starts. One Van Nuys customer describes three skylights replaced even though light showers fell that morning. We will tell you what the forecast does to the schedule.
Should I add skylights while re-roofing?
It is the cheapest time to do it, because the roof is already open and the flashing goes in with the new roofing. The cost is a new opening, which brings framing, interior shaft work and possibly permit review. Think about heat gain and furniture placement before choosing spots. Skylights added later mean cutting into a finished roof.
Do I need a curb for a new skylight?
Not always. Curb-mounted units sit on a raised box built on the roof and suit flat and low-slope roofs. Deck-mounted units fit flush on pitched roofs and use a flashing kit. We look at the slope, the roofing and the existing opening before recommending one, because the wrong mount is a leak waiting to happen.
Are solar tubes a good alternative to skylights in Los Angeles homes?
For small, dark spaces such as a hallway, closet or bathroom, a tubular daylight device often fits where a full skylight would not. It needs a small roof opening and a flexible tube through the attic, with no framing change. It gives less light and no view, so it works for brightening a space, not for a feature window.
Areas served for skylight replacement
- South Whittier, CAPostwar tract homes with a median build year of 1957 (Census ACS) put many original skylights past their sealed-glass life, in an unincorporated area under county permitting.
- Agua Dulce, CAStrong sun at about 2,500 feet in the Sierra Pelona Valley wears acrylic domes quickly, and ranch lots mean long runs for hauling a unit to the roof.
- Costa Mesa, CAMixed apartments and commercial buildings, a mile or so from the ocean, so curb-mounted skylights on low-slope roofs and salt-resistant flashing both come up.
- El Monte, CAOlder homes and multi-unit buildings in the central San Gabriel Valley, where a skylight swap in the same opening is the common case and the city issues its own permits.
- Palos Verdes Estates, CAA strong red-tile tradition and an Art Jury review mean a visible skylight or sun tunnel needs approval before the unit is ordered.
- Port Hueneme, CABeachfront condos take direct salt exposure, so the flashing metal and fasteners on a new skylight matter as much as the glass.
- Beverly Hills, CAClay tile on Period Revival homes means each tile around a skylight opening is lifted and reset by hand, and the city runs its own building department.
- West Puente Valley, CAA median build year of 1956 (Census ACS) and county-issued permits for unincorporated areas; older skylights here are often due for replacement with the roof.
- Chino Hills, CALarge 1990s tracts (median build 1990, Census ACS) governed by HOAs, so approval for a visible skylight comes first, and hot hillside exposure speeds seal wear.
