Skylights in Rosemead, CA bring daylight into hallways, kitchens and baths that older floor plans left dark, but every one is also a hole in the roof. Most skylight problems we see are roofing problems: tired flashing, a curb that was sealed instead of flashed, or a plastic dome that has cracked after years of summer sun. We treat skylight work as a branch of our roofing service in Rosemead, done by the same crews who repair and replace the roof around it.
This page covers the three skylight services we offer, the types of skylights common in San Gabriel Valley homes, and how we decide whether yours needs repair, replacement or removal.
Skylight services in Rosemead, CA: repair, replace or install
- Skylight repair: tracing and fixing leaks at the flashing, curb or seal, plus dome and condensation problems.
- Skylight replacement: swapping old acrylic domes and fogged glass units for new ones, or removing a skylight and roofing over the opening.
- Skylight installation: new fixed, venting or tubular skylights framed into the roof and flashed for its material.
Many homes here were built in the 1950s and 1960s with no skylights at all, then had domes added in later remodels. Those add-ons are often the ones leaking now, because they were set on site-built wood curbs with roofing cement instead of a flashing kit.
What every skylight job includes
- An inspection from the roof, the room below and the attic, so the cause is found before anything is ordered.
- Flashing matched to the roof: a kit for deck-mounted units, a built and flashed curb for curb-mounted ones, a formed pan under tile.
- Self-adhered membrane around the opening before the roofing goes back.
- Shingles rewoven or tile cut and reset around the unit, never sealant standing in for metal.
- Photos of the flashing before the roofing covers it, and a dry-day hose test when a leak is involved.
Why is your skylight leaking?
A drip near a skylight does not always come from the skylight. We check the unit and the roof around it, since both can send water down the light shaft.
| Source | What fails | Telltale sign |
|---|---|---|
| Curb or step flashing | Sealant dries out, flashing laps too short | Leak in heavy or wind-driven rain only |
| Uphill side of the curb | Leaves and grit dam water against the headwall | Stain on the upper edge of the shaft |
| Dome or glass | Cracked acrylic or failed glazing seal | Drip from the center, fogging between panes |
| Roof around the skylight | Worn shingles, slipped tile, old underlayment | Stain spreading beyond the shaft |
| Condensation | Warm, moist air meeting cold glass | Droplets on winter mornings, dry afternoons |
Leaks that appear only in heavy storms usually point to flashing or debris on the uphill side. Our guide to leaking skylights explains how to tell flashing, seal and replacement problems apart.
Fixed, venting and tubular skylights compared
| Type | Best suited to | Notes |
|---|---|---|
| Fixed deck-mounted glass | Kitchens, living rooms, vaulted ceilings | Low profile, flashed with a kit; no ventilation |
| Venting (manual, electric or solar-powered) | Bathrooms and kitchens that trap heat and steam | Opens to let hot air out; many close automatically in rain |
| Tubular skylight or sun tunnel | Hallways, closets, small baths under an attic | Small roof opening, reflective tube, no shaft framing |
| Curb-mounted acrylic dome | Older remodels and flat roofs | Inexpensive originally; yellows and cracks over time |
Velux and Solatube are common market examples for glass skylights and tubular units. Our comparison of fixed, venting and tubular skylights goes through each option in more detail.
How we decide between repair, replacement and removal
- Repair when the unit itself is sound and the leak comes from flashing, sealant or debris.
- Replace when the dome is brittle or cracked, the glass seal has failed, or the frame is warped.
- Replace during a reroof when the skylight is older than the roof going on, since the flashing is being rebuilt anyway.
- Remove and roof over when the skylight overheats the room, leaks repeatedly, or sits where solar panels need the space.

Skylight work, step by step
- Inspection from the roof and the room below, including the light shaft and attic.
- Photos of the unit, flashing and surrounding roof, with a written quote.
- Permit when the job cuts a new opening or changes framing.
- Roofing removed around the opening, unit and flashing installed, roofing rewoven or tile reset.
- Interior trim or shaft finish noted separately when drywall is affected.
- Hose test on a dry day when a leak repair needs confirming.
Most repairs and like-for-like replacements take a day or less. New installs with framing and a drywall shaft run longer, and tile roofs add time for lifting and resetting tile.
What drives the cost of a skylight project?
- Unit type and size: fixed glass, venting, solar-powered venting or tubular.
- Roof material, since tile and flat roofs take more flashing work than shingles.
- Whether the opening is new, reused or being closed.
- Curb or framing repair if rot is found around an old unit.
- Interior shaft and drywall work, which is separate from roofing.
We quote each item line by line after the inspection. Ask about payment options if you are combining skylights with a larger roof project.
Two choices move the total more than the unit price. Doing skylight work while the roof is already open for a reroof shares the tear-off and flashing labor, and replacing a unit in its existing opening skips framing and drywall. A brand-new opening, a venting unit that needs wiring, or a tile roof all add labor. Our skylight replacement cost guide breaks those lines down further.
Skylight permits, energy labels and roofer licensing
Cutting a new opening or changing rafters needs a building permit: from Rosemead's Building and Safety Division in the city, and from LA County Public Works Building & Safety in unincorporated communities. Title 24 also sets energy limits for new and replacement skylights, shown as U-factor and solar heat gain on the unit's NFRC label, so the label stays on until the inspector has seen it.
Any skylight job above $1,000 in labor and materials requires a CSLB-licensed contractor under B&P Code §7048, and work that reflashes the roof falls under the C-39 roofing class. Look up the number at cslb.ca.gov before work starts.

Skylights questions
Should old skylights be replaced when the roof is replaced?
Usually, if the skylight is near the age of the old roof or is a plastic dome on a wood curb. The flashing gets rebuilt during a reroof either way, so replacing the unit then costs less than coming back later and cutting into a new roof. A newer glass skylight in good shape can stay and be reflashed.
Why is my skylight leaking only in heavy rain?
Heavy or wind-driven rain overwhelms flashing that handles light showers, especially when laps are short or debris has collected above the curb. Old sealant joints also open under that volume of water. We check the headwall, step flashing and the roof above the skylight first.
Do you install tubular skylights?
Yes. Tubular skylights, also called sun tunnels, suit hallways, closets and small bathrooms under an attic. They need only a small roof opening and a reflective tube to the ceiling, so no framed shaft is required. We flash them for shingle, tile or flat roofs.
Do skylights work on tile roofs?
Yes, with the right flashing. Tile roofs need a flashing kit or custom pan sized for the tile profile, and the tiles around the curb have to be cut and reset carefully. Many leaks on tile skylights come from flashing designed for shingles being used under tile.
Does skylight work need a permit?
Cutting a new opening or changing roof framing usually needs a building permit, and some cities also want one for replacements. Rules vary by city, and unincorporated areas follow LA County Public Works Building & Safety. We look up the rules that apply at your address and file for the permit if one is needed.
Is fog inside my skylight a leak?
Fog or droplets between two panes of glass mean the glazing seal has failed, which calls for replacing the unit. Droplets on the room side on cool mornings are condensation from indoor moisture, not a roof leak. Better bathroom ventilation or a newer insulated unit usually solves condensation.
