Skylight Installation Cost in Los Angeles: 2026 Price Guide
Skylight installation in Los Angeles costs $1,400 to $4,500 in 2026. Real prices by skylight type, roof material, and what LA homeowners should expect.
Skylight installation in Los Angeles costs $1,400 to $4,500 for most homes in 2026. The number swings on the skylight type, your roof material, and whether the crew is cutting a fresh hole or swapping out an existing unit. A simple fixed skylight on an asphalt shingle roof sits at the low end. A vented electric unit on a tile roof in the hills runs near the top.
This is the working price guide we hand homeowners who call asking what a new skylight runs. The ranges below match what LA crews are quoting this summer.
How Much Does Skylight Installation Cost in Los Angeles?
Most quotes break down by skylight type. Each type sits in a fairly tight range before the roof and labor factors push the final number.
| Skylight Type | Low | Average | High |
|---|---|---|---|
| Fixed (non-opening) acrylic dome | $1,400 | $2,000 | $2,800 |
| Fixed glass deck-mounted | $1,800 | $2,600 | $3,800 |
| Manual vented (hand crank) | $2,200 | $3,000 | $4,200 |
| Electric or solar-powered vented | $2,800 | $3,800 | $5,500 |
| Tubular skylight (sun tunnel) | $900 | $1,400 | $2,200 |
| Custom or oversized unit | $4,000 | $6,500 | $12,000 |
Most LA homeowners installing one standard skylight land between $2,200 and $3,500. A pair of matching skylights in a kitchen or living room usually runs $4,000 to $6,500 once both are in. Tubular units stay cheap because the hole is small and the flashing kit is pre-made.
What Affects the Price
Six factors move your number inside those ranges.
Skylight unit cost. A basic fixed acrylic dome runs $200 to $450 at the supply house. A premium VELUX or Fakro electric vented unit with rain sensor and blinds runs $900 to $2,400. The unit itself is often a third of the total job.
Roof material. Asphalt shingle roofs are the cheapest to cut into. Tile roofs cost more because the crew has to lift, set aside, and reset tiles around the curb without cracking them. Flat roofs with TPO or modified bitumen need a heat-welded membrane patch around the curb. Slate and metal are the priciest.
New cut vs replacement. Cutting a fresh hole in your roof means framing the curb, sistering rafters if the opening is wide, and patching the ceiling drywall inside. A straight swap of an old skylight for a new one of the same size skips all of that. New cuts cost $800 to $1,500 more than a replacement.
Number of stories and access. Two-story homes add labor time. Hillside homes in Mount Washington, Silver Lake, or the Hollywood Hills sometimes need a small lift or scaffolding, which adds $400 to $900.
Electrical work. Electric and solar-powered vented units need a wire run from a switch to the skylight motor. If your attic is open and accessible, that is a one-hour job. If walls have to be opened, an electrician adds $300 to $800.
Permits. LA city and county both require a permit for cutting a new skylight opening because it changes the roof framing. Permit fees run $180 to $450 depending on the jurisdiction. A like-for-like replacement usually does not need one.
What a Proper Skylight Installation Includes
A full quote from a roofer should cover all of this. If it does not, you are looking at an underbid that will surprise you mid-job.
- The skylight unit itself, with model number listed
- Framing for the curb (2x lumber, headers, and any rafter sistering)
- Step flashing kit matched to your roof material
- Underlayment patch around the new opening
- Ice and water shield around the curb (yes, even in LA)
- Interior drywall patch and finish around the shaft
- Cleanup and haul-away of debris
- Permit pulling and final inspection when required
Skipping the flashing kit is the most common shortcut on cheap quotes. A skylight installed with just caulk around the curb will leak inside two years. A proper step flashing install with counterflashing lasts the life of the roof.
How LA-Specific Factors Affect the Cost
A few things make skylight installs in Los Angeles run higher than national averages.
LA labor rates run 20 to 30 percent above the national mean. A roofer in the Midwest billing $65 an hour bills $85 to $95 here. That shows up in every line item.
Tile roofs are everywhere in LA. Spanish, mission, and concrete tile add 25 to 40 percent to the install cost compared to a shingle roof. Tiles have to be matched if any crack during the cut, and finding replacements for older tile profiles takes legwork.
Title 24 energy code requires skylights in new openings to meet a U-factor and SHGC rating. That rules out the cheapest acrylic domes for permitted jobs. You end up specifying a glass unit with a low-e coating, which is $200 to $500 more than the base model.
Fire-zone homes in the foothills need skylights with tempered glass and Class A fire-rated assemblies. That is another $300 to $600 on the unit cost. Homes in Pacific Palisades, Malibu, and the foothill neighborhoods deal with this most.
Comparison to National Averages
National data puts the average skylight install at $1,900 to $2,500. LA averages run $2,200 to $3,500 for the same job. The gap is labor and material. Add a tile roof and the LA number can be double the national average.
Get a quote that lines up with the ranges above and you are in normal territory. A quote significantly below them usually means the flashing kit, the drywall finish, or the permit is missing.
Tubular Skylights: The Budget Option
If you want natural light in a hallway, closet, or small bathroom without the cost of a full skylight, a tubular skylight (sometimes called a sun tunnel or solar tube) does the job for $900 to $2,200 installed. The unit pipes daylight from a roof dome down a reflective tube into a small ceiling lens. No framing, no drywall shaft, and no electrical. Most install in three to four hours.
Frequently Asked Questions
How long does skylight installation take?
A like-for-like replacement takes four to six hours. A new cut with interior drywall finish takes one to two days. Electric vented units with new wiring add another half day if walls have to be opened.
Do I need a permit to install a skylight in Los Angeles?
Yes for a new opening, no for a like-for-like replacement of the same size. New openings change the roof framing and require a permit and final inspection in both LA city and county jurisdictions. Permit fees run $180 to $450.
What is the best skylight brand for Los Angeles homes?
VELUX and Fakro dominate the LA market for good reason. Both make Title 24 compliant units, both have step flashing kits matched to tile and shingle, and both carry strong warranties. VELUX is more common in residential work. Fakro is competitive on price and has a strong vented electric line.
Will a new skylight leak?
A skylight installed with proper step flashing, counterflashing, and an ice and water shield around the curb should not leak for the life of the roof. Leaks almost always come from skipped flashing, old caulk-only seals, or curb framing that rotted before the skylight went in. A roof inspection before the install catches framing issues.
Can a skylight be added to a flat roof?
Yes. Flat roof skylights use a raised curb with a TPO, PVC, or modified bitumen membrane heat-welded around it. Cost runs $2,400 to $4,800 for a standard unit, more for custom sizes. The membrane work is what separates a flat-roof install from a pitched-roof install.
How long do skylights last?
Acrylic domes last 15 to 20 years before the plastic clouds and cracks. Glass deck-mounted units last 25 to 30 years if the seal stays intact. Flashing kits last the life of the surrounding roof, so coordinate skylight replacement with your next roof replacement when possible.
The Bottom Line on Skylight Cost in LA
Budget $2,200 to $3,500 for one standard skylight on an average LA home. Tile roofs, vented units, and new openings push the number up. Tubular units and like-for-like swaps bring it down. Get the flashing kit and permit in writing on every quote.
