Skylight replacement in Rosemead usually means removing an old acrylic dome or a glass unit with a failed seal, installing a new skylight in the same opening, and rebuilding the flashing around it. When a skylight causes more trouble than light, we can also remove it and roof over the hole. Replacement is one of three services within our skylight work, alongside repair and new installs.
Many skylights in San Gabriel Valley homes were added during remodels decades ago. After years of strong sun, those units tend to fail together: the plastic yellows, the seal lets go, and the mastic around the curb cracks.
How long do skylights last before they need replacing?
Lifespan depends on the material and how the unit was installed. Under strong Southern California sun, these are the patterns we see:
| Skylight type | What wears out | Signs it is time |
|---|---|---|
| Acrylic or polycarbonate dome | Plastic turns brittle and yellow in UV | Cloudy, crazed or cracked dome; leaks at the corners |
| Older single-pane glass | Seals and frame gaskets | Drafts, heat gain, drips at the frame |
| Insulated glass unit | Seal between the panes | Fog or moisture trapped between the glass |
| Site-built wood curb | Wood rots from slow leaks | Soft curb, stained shaft, loose fasteners |
Flashing often fails before the unit does. If the skylight itself is sound, our skylight repair service may solve the leak without a new unit.
Replacement options: like-for-like, upgrade or roof it over
Same opening, new unit
The simplest path. We remove the old skylight, inspect the curb, and install a new unit sized for the existing opening, with a new flashing kit. Curb-mounted replacements are made in many common sizes.
Dome to glass
Swapping a plastic dome for a flat, low-E glass unit cuts heat gain and noise from rain, and lasts longer in the sun. We often rebuild or replace the old wood curb at the same time.
Resize or convert
A larger or smaller unit means reframing the opening. Some owners replace a big, hot skylight with a tubular unit, which needs only a small roof hole. Our skylight installation page covers new framing and tube options.
Remove and close the opening
If you no longer want the skylight, we frame in the opening, add new deck, underlayment and roofing, and the ceiling gets patched below.
What a replacement includes
- Removal and disposal of the old unit, its mastic and any rusted flashing.
- A probe of the curb and surrounding deck, with photos before any wood is replaced.
- The manufacturer's flashing kit for the new unit, since some makers tie coverage to their own kit.
- Self-adhered membrane lapped up the curb and onto the deck before the roofing closes in.
- Interior trim or shaft touch-up, priced separately when drywall is affected.
Is it cheaper to replace skylights during a reroof?
Usually, yes. A reroof already strips the shingles or tile surrounding each skylight, which is the most labor-intensive part of a replacement. Replacing later means cutting into new roofing and matching it.
- The new flashing kit goes in with the new underlayment, lapped correctly from the start.
- Rotted curbs or deck around the opening get fixed while everything is exposed.
- There is one permit and one cleanup instead of two.
- You avoid a fresh roof patch next to brand-new shingles or tile.
When you request a roof replacement quote, each skylight gets its own price so you can decide unit by unit. If solar is in your plans, this is also the moment to decide whether a skylight should stay where the array would sit; removing it before panels go on is far simpler than working around it later.
Removing a skylight and patching the roof
Closing a skylight opening is a small framing and roofing job. Done right, it leaves no weak spot.
- Remove the skylight, curb and flashing.
- Frame the opening flush with the rafters and add new sheathing.
- Lay underlayment that overlaps the existing layer on all sides.
- Weave in shingles or set tile to match the surrounding roof.
- Close the light shaft in the attic and patch the ceiling drywall.
On older roofs, new shingles may look a shade different from weathered ones at first. On tile roofs we reuse tiles from the job or find matches. Drywall and paint can be done by your painter or listed on our quote.

The skylight replacement process and timeline
- Inspection of the unit, curb, flashing, shaft and roof around it.
- Measurements and options, with photos and a written quote.
- Permit if your city requires one for the work.
- Removal of the old unit, curb repair and new skylight installation.
- New flashing woven into the roof, then interior trim as needed.
A like-for-like swap on a shingle roof often takes half a day to a day. Tile roofs, curb rebuilds, resized openings and removals with drywall work take longer. We cover the opening if weather turns mid-job. Inside, floors and furniture under the shaft get drop cloths, since old curb debris and insulation can fall when the unit comes out.
Same-size swaps are permitted in some cities and exempt in others, so we check with Rosemead's Building and Safety Division or, on unincorporated streets, LA County Public Works Building & Safety. Either way the new unit has to meet Title 24's skylight limits, which you can read on its NFRC sticker. A replacement that runs over $1,000 in labor and materials, the B&P Code §7048 limit, needs a CSLB-licensed contractor, and you can confirm a roofer's C-39 license at cslb.ca.gov.
What sets the cost of replacing a skylight?
- Unit type: fixed glass, venting, solar-powered or tubular.
- Whether the opening stays the same size.
- Curb or deck rot found when the old unit comes out.
- Roof material, since tile adds handling time.
- Interior shaft and ceiling work.
The curb decides more than the unit. If the old wood curb is sound and the new skylight is made for that size, the swap is mostly flashing labor. A rotted curb, a discontinued size that forces reframing, or a dome-to-glass upgrade on a low-slope roof adds framing and membrane work. Replacing several units in one visit shares setup and cleanup.
Our article on skylight replacement cost explains these factors in more depth. Your quote lists each one separately, and you can ask about payment options.

Skylight Replacement questions
How long do skylights last before they need replacing?
It varies with the material and the installation. Plastic domes tend to yellow, turn brittle and crack first under strong sun. Insulated glass units last longer but eventually lose the seal between panes and fog. Flashing often fails before either. We check the unit and flashing to tell you which part is actually worn out.
Can a skylight be removed and the roof patched over?
Yes. We remove the unit and curb, frame the opening flush with the rafters, add new sheathing and underlayment that overlaps the existing roof, and match the shingles or tile. Then the shaft is closed and the ceiling patched. Done properly, the patch is as watertight as the rest of the roof.
Is it cheaper to replace skylights during a reroof?
Usually. Since the reroof already exposes the skylight's surroundings, you skip a separate tear-out, a second cleanup and a later patch in new roofing. Replacing an aging skylight then also means its flashing is installed with the new underlayment, which is the right moment to get it right.
Can a new skylight fit my existing opening?
Often. Many replacement units come in sizes made for common older openings, and curb-mounted models can fit an existing curb. If the old size is no longer made, we adjust the curb or reframe slightly. We measure before recommending a unit.
Why has my dome skylight turned yellow and cloudy?
Acrylic and polycarbonate break down under ultraviolet light. Over years of strong sun the plastic yellows, loses clarity and grows fine surface cracks called crazing, and it becomes brittle enough to crack from a falling branch or hail. Cleaning will not reverse it. Yellowing is a sign the dome is near the end of its life and worth replacing before it fails in a storm.
Should I replace a dome skylight with glass?
In most cases, yes. A flat, low-E glass unit cuts heat gain, quiets rain noise and resists UV far longer than acrylic. Code-required laminated glass also stays together if broken. A tubular unit is another option if you only need modest light.
Do I need a permit to replace a skylight?
It depends on the city and the scope. Same-size replacements may not need one in some places, while resizing or reframing usually does. We check with your building department and pull the permit when required.
