Skylight installation in Rosemead is a roofing job before it is a lighting job. A new skylight means cutting through the deck, framing the opening, and flashing it into shingle, tile or a flat roof so water flows around it for as long as the roof lasts. It is the new-install branch of our skylight services, handled by roofing crews rather than general handymen.
Post-war ranch homes in the San Gabriel Valley often have long interior hallways and windowless bathrooms. Those are the spaces where a skylight or tubular unit changes the room most.
Choosing a new skylight: fixed, venting or tubular
| Option | What it does | Good fit |
|---|---|---|
| Fixed glass skylight | Lets in daylight; does not open | Living rooms, kitchens, vaulted ceilings |
| Manual or electric venting skylight | Opens to release heat and steam | Kitchens, bathrooms, upstairs rooms |
| Solar-powered venting skylight | Opens by remote; many models close on a rain sensor | Spots where running new wiring is hard |
| Tubular skylight (10 or 14 inch) | Reflective tube carries light through the attic | Hallways, closets, laundry rooms, small baths |
As market examples, Velux makes fixed, Fresh Air and Solar Powered Fresh Air skylights plus the Sun Tunnel tubular line, and Solatube is a widely known tubular brand. Code requires safety glazing in skylights, so most glass units use a laminated inner pane that holds together if broken.

What a new skylight installation includes
- An attic survey for rafters, wiring and ducts before the ceiling or roof is marked.
- Headers and framing where a rafter has to be cut, or a fit between rafters where it does not.
- The maker's flashing kit for that unit and roof type, over self-adhered membrane.
- The light shaft framed and drywalled, or the tube and ceiling diffuser installed.
- Floor and furniture protection below the opening, then cleanup of dust and offcuts.
Electric venting units also need a power feed and switch, which we coordinate with an electrician when one is not already in the attic.
Where should a new skylight go?
Placement decides how much light you get, how much heat comes with it, and how easy the roof is to keep dry.
- Between rafters when possible: many units are sized to fit standard rafter spacing, which avoids cutting structure.
- Away from valleys and the uphill side of chimneys, where water and debris concentrate.
- North-facing slopes give soft, even light; south and west slopes add more summer heat.
- A splayed shaft spreads light wider in the room than a straight one, at the cost of more framing.
- Clear of planned solar arrays, vents and satellite mounts.
We measure from the attic first, find rafters and wiring, and mark the ceiling and roof before cutting anything.
Which rooms benefit most from a tubular skylight?
Tubular skylights need only a small round roof opening and no framed shaft, so they suit rooms where a full skylight would be overkill:
- Interior hallways with no windows.
- Walk-in closets and laundry rooms.
- Small bathrooms, where some units add an optional vent or light kit.
- Kitchens with a dark corner far from the window.
They work when there is an attic between roof and ceiling. Rooms with vaulted ceilings usually need a standard skylight instead. Tubes add very little heat compared with a large glass skylight. As a rough guide, a 10-inch tube suits a hallway or closet, while a 14-inch tube lights a larger bathroom or a kitchen work area.

How we frame, flash and finish a new skylight
- Layout: locate rafters, wiring and ducts from the attic, then mark the opening.
- Opening: cut the roofing and deck, and add headers if a rafter must be cut.
- Mounting: set the unit on its curb or deck brackets, square and level.
- Waterproofing: wrap self-adhered membrane up the sides of the frame and onto the deck.
- Flashing: install the maker's flashing kit, then reweave shingles, cut and reset tile, or strip in a flat-roof membrane.
- Interior: frame and drywall the light shaft, or install the tube and ceiling diffuser.

A tubular skylight is often done in a few hours. A framed glass skylight with a drywall shaft typically takes 1 to 2 days, plus time for drywall finishing and paint. Tile roofs add time for handling tile.

Permits and the energy code for new skylights
Cutting a new opening in the roof usually requires a building permit, especially when framing changes. We check the rules for your address, pull the permit and book the inspection. In unincorporated Mayflower Village, for example, the permitting office is LA County Public Works Building & Safety.
California's energy code also limits how much heat skylight glazing can let through. We use units with NFRC ratings for U-factor and solar heat gain and keep the labels for the inspector.
A new skylight is rarely a minor job under B&P Code §7048, which caps unlicensed work at $1,000 in labor and materials, so the installer should hold an active CSLB license; roofers work under the C-39 class. Check the number and workers' compensation record at cslb.ca.gov before anyone cuts the deck.
Will a skylight make your room hotter in summer?
It can if the wrong unit goes in the wrong place. With summer highs around 78 to 88°F here, we steer you toward:
- Low-E glass with a low solar heat gain rating.
- North or east slopes for large fixed units.
- Venting skylights in kitchens and baths, so hot air can escape.
- Optional blinds or shades, some solar-powered.
- Tubular units where you want light without much heat.
Size matters as much as glass. A skylight scaled to the room lights it without turning it into a greenhouse, and the units owners regret are usually oversized ones on west slopes. We size the unit to the floor area before you order.
What shapes skylight installation cost?
- Unit type, size and options such as venting, blinds or rain sensors.
- Roof material: shingle, tile or flat membrane.
- Framing: fitting between rafters versus adding headers.
- Shaft length and shape, plus drywall and paint.
- Permit and inspection.
The biggest swing is the shaft. A unit fitted between rafters over a short, straight shaft is the simplest case, while a splayed shaft, a long drop through a deep attic or a cut rafter adds framing and drywall time. A tubular unit skips the shaft entirely. Installing during a planned reroof shares the roofing labor around the opening.
Each item appears on its own line in the written quote. Ask about payment options if you are adding several skylights at once.
Why homeowners trust us to cut into their roof
- Roofers install the unit and its flashing, so one crew answers for keeping it dry.
- Reviewers mention crews that protect floors and furniture and clean up when done.
- Photos of the framing, membrane and flashing come with the job, since they disappear under the roofing.
- Google reviews put us at 4.9 stars across 48 ratings as of November 2026.

The skylight maker sets coverage for each unit and option, and your contract lays out our workmanship terms. Ask for each in writing and whether it transfers to a new owner. If an existing skylight needs attention too, see skylight replacement or skylight repair.
We install skylights and sun tunnels in Temple City, Glendora and East Pasadena, as well as nearby SGV neighborhoods.

Skylight Installation questions
Does a new skylight need a permit?
Usually, yes. A new opening cuts through the roof deck and often the framing, which most cities treat as permitted work, and the energy code sets glazing limits for skylights. We confirm requirements with your building department, then handle the permit and inspection, which show as their own charge on the quote.
Which rooms benefit most from a tubular skylight?
Interior hallways, closets, laundry rooms and small bathrooms gain the most, because they often have no windows and only need a modest amount of light. Tubes run through the attic, so they work under a flat ceiling with attic space above. For vaulted ceilings, a standard skylight is usually the better fit.
Will a skylight make my room hotter in summer?
A poorly chosen one can. Low-E glass, a low solar heat gain rating, north or east placement and a venting unit all keep heat down. Blinds help on west slopes. Tubular skylights add very little heat. We go over orientation and glass options before you order.
Can you install a skylight in a tile roof?
Yes. We cut and reset the tiles around the opening and use flashing designed for the tile profile, not a shingle kit. Clay tile needs extra care because it breaks easily. Spare tiles matching your roof help, and we look for matches when none are on hand.
Do venting skylights close automatically when it rains?
Many electric and solar-powered venting models include a rain sensor that closes them when water hits it. Manual venting units do not, so they need to be closed before you leave the house. We point out which models include the sensor when you are choosing.
How long does skylight installation take?
A tubular skylight often takes a few hours. A framed glass skylight with a new drywall shaft usually takes 1 to 2 days on site, plus drywall finishing time. Tile roofs and skylights that need new headers take longer. We give you the schedule with the quote.
