Daylight without leaks
Skylight installation in Long Beach, CA
A dark hallway, an interior bathroom or a kitchen with no window could use daylight. A skylight brings it in, but only if it is framed and flashed so it never leaks.

Skylight installation is cutting a new opening in your roof, framing it, setting a skylight unit and flashing it into the roofing so water runs around it. It suits rooms with little window light, or replacing an old cloudy or leaking skylight. Typical installs run $1,150 to $3,400 per skylight, depending on size, roof type and interior finish work.
A skylight can change how a room feels. Interior hallways, bathrooms and kitchens in older Long Beach homes are often dim even at noon, and a single well-placed skylight lights them for most of the day. In a sunny climate, that light comes in strong, so the size, glazing and placement matter as much as the install itself.
The roof side of the job is where skylights succeed or fail. A skylight is a big hole in your roof, and the flashing around it has to shed water under heavy, wind-driven rain. Our roofers frame the opening, set the unit, and flash it into the roof using parts made for your roof type, then finish the shaft or light well inside to the level you choose.
Choosing the skylight: fixed, venting or tubular
Fixed skylights do not open. They are the simplest choice for daylight in hallways, living rooms and stairwells. Venting skylights open by hand crank or motor and help release heat and moisture, which makes them popular in bathrooms and kitchens. Tubular skylights use a small roof dome and a reflective tube to carry light down into a closet, bathroom or hallway where a full skylight would not fit.
Glazing matters in Long Beach sun. Low-E coated glass reduces heat and fading while still letting light in. Laminated or tempered glass is the safer choice overhead. Acrylic domes are cheaper but yellow and cloud with UV over time, which is why many old domes on 1960s and 1970s homes now look milky.
- Fixed skylights for daylight with no moving parts
- Venting skylights for bathrooms and kitchens
- Tubular skylights for small or awkward spaces
- Low-E, laminated glass for sun and safety
- Optional shades to control afternoon heat
Framing and flashing on tile, shingle and flat roofs
We locate rafters from the attic, then frame the opening with headers so the roof structure stays strong around the cut. The skylight is set either on a raised curb or directly on the deck, depending on the unit and the roof. Then comes the flashing, which is the part that keeps water out.
On shingle, step flashing or a matched flashing kit weaves into the shingle courses. On tile, we use a flashing kit with a high profile apron, plus a pan and sometimes a cricket uphill so water from the tile above is guided around the skylight. On flat roofs, the curb is wrapped and sealed into the membrane so the skylight sits above any standing water.

Placement, heat and the light well
Where the skylight sits on the roof changes what you get inside. A north-facing slope gives steady, soft light with less heat. South and west slopes bring more light and more afternoon heat, which can be handled with low-E glass and shades. We look at roof slope direction, rafter spacing, attic obstructions and where the light lands in the room before we cut.
Between the roof and the ceiling is the light well, or shaft. A straight shaft is simplest. A flared shaft spreads light wider into the room. We frame and drywall the shaft, and finish painting or leave it ready for your painter, depending on what you want included.
When to call about skylight installation
Dark interior rooms
Hallways, bathrooms and kitchens without good windows are the most common places a skylight makes a big difference.
Old cloudy dome
Yellowed acrylic domes from decades ago let in less light each year and are often near the end of their life.
Leaking old skylight
When an old unit leaks repeatedly, replacing it with a properly flashed new one is often better than another patch.
Re-roof planned
A roof replacement is the ideal time to add or replace skylights, since the roofing around them is new.
Moist bathroom
A venting skylight helps clear steam from bathrooms without fans running all day.
Kitchen remodel
Kitchen remodels often add skylights over work areas, and the roof work should be planned with the layout.

Skylights in Long Beach homes, from Craftsman hallways to mid-century ranchos
Older homes in Bluff Park, Belmont Heights and California Heights often have deep interior hallways and small bathrooms that get little natural light. Skylights brighten them without changing the street view much, but in historic districts a skylight on a slope facing the street can need review, so we usually suggest rear or side slopes. Mid-century homes in Rancho Estates, the Plaza and Los Altos took to skylights early, and many still carry original domes that are cloudy, cracked or leaking.
Long Beach sun is strong much of the year, so we often recommend low-E glass and a shade on south and west slopes. Near the water in Naples and Belmont Shore, we choose corrosion-resistant flashing and fasteners. Cutting a new opening in a roof is structural work, and we pull permits where the city requires them.

FAQ
Skylight Installation questions
How long does skylight installation take on a Long Beach home?
Most single skylight installs on shingle roofs take a day, including the light well. Tile roofs and long or flared shafts can add time. Drywall finishing and paint may stretch the inside work over a second visit.
Can a skylight be installed on a clay tile roof without leaking?
Yes, if it is flashed with a kit made for tile and the underlayment is lapped correctly around it. We often add a small cricket uphill of the skylight so water from above is directed around it. Most tile skylight leaks we see come from shortcuts in the flashing.
Is a tubular skylight a good option for a small Long Beach bathroom?
Often, yes. A tubular skylight needs only a small roof opening and carries light through a reflective tube into a bathroom, closet or hallway. It costs less than a full skylight and works well where rafters or attic space are tight.
Should I replace an old skylight during skylight installation on the rest of my roof?
If the old unit is cloudy, cracked or past the point of reliable flashing, replacing it while we are on the roof saves a second trip. We will look at it and tell you whether it still has life. Pairing the work saves on labor and scaffolding.
Do new skylights make rooms too hot in Long Beach summers?
They can on south and west slopes if the glass is clear and there is no shade. Low-E glass and optional blinds cut much of that heat. North-facing placement gives soft light with little heat gain.
