Skylights

Skylight installation in San Diego.

A skylight can brighten a dark room. A badly flashed skylight can become a leak. Ask the matched roofer which flashing kit they will use for your roof type, who does the interior light shaft, and whether they currently hold the manufacturer credentials they claim. Proper curb and counter-flashing is what keeps water out.

Skylight installation in San Diego: the decisions that matter

Why the flashing kit is more important than the skylight itself

The most common skylight failure in San Diego is not the unit, it is the flashing. Velux and other manufacturers make watertight units. What fails is the integration between the frame and the surrounding roof, and that depends on matching the flashing kit to the roof type and installing it correctly. Velux makes several flashing kits: EW (shingle and shake), EDW and ED (tile, curb mounted to prevent tile interference), EMD (metal, for standing seam or corrugated), and custom EFW for unusual applications. Using the wrong kit is the most common installation mistake. An EW kit into a tile roof will fail because the shingle-specific saddles do not match tile course heights and lapping geometry. Sequence matters as much as the kit: step-flashing must interleave with courses above, the head flashing must lap over the uphill course, and the sill flashing must integrate with the drainage plane below. Skipping any step creates a leak path. We match you with a licensed independent roofer. Ask which flashing kit they will use for your roof type, whether they hold current manufacturer credentials, and get permit, warranty, and method in writing. This is not a corner-cutting category.

Deck-mounted vs. curb-mounted skylights: the right choice for San Diego

Velux's residential line comes in two mounting types. Deck-mounted (VS, FS, VSS series) sits directly against the roof deck with integrated flashing. These are the standard residential choice and work well on shingle, shake, and most low-profile tile. Deck-mounted is slightly lower-profile and suits most California ranch and contemporary homes. Curb-mounted (FCM series) sits on a raised wood frame built into the roof structure. Required for flat and very low-slope sections (under 15 degrees), and recommended for tile where tile thickness conflicts with deck-mounted flashing kits. Curb-mounted also helps in snow (rare in San Diego, relevant for mountain homes in Julian or Pine Valley): the raised curb keeps debris and water from banking against the frame. Sun Tunnels (TMF and TWF) are a different category: rigid or flexible tubes that transfer light from a rooftop collector to an interior room without cutting a full ceiling opening. The rigid version (TMF) works for rooms directly below the roof; the flexible version (TWF) can make bends. Useful for hallways, closets, and bathrooms where a full skylight would require rafter cutting, with less interior disruption. Confirm mount type, flashing kit, permit, and warranty in writing with the matched licensed independent roofer.

Solar tax credit and the Velux VSS: the math San Diego homeowners miss

For years the Velux VSS (Solar Powered Vented Skylight) qualified for the 30% federal Residential Clean Energy Credit because it uses photovoltaic power to operate its motor, rain sensor, and remote control. That credit expired for installs placed in service after December 31, 2025, so a 2026 VSS install can't count on it. If your skylight went in by the end of 2025, you can still claim the credit when you file: it applied to the full installed cost (unit plus labor plus materials) as a dollar-for-dollar tax liability reduction, documented on IRS Form 5695. For a 2026 install, price the VSS on its own merits and treat any contractor pitch built around a federal credit as a red flag. Consult a tax professional for your specific situation, and ask at quote time whether any current utility or state incentive applies. The VSS still earns its premium in one practical way: it closes automatically when it rains, which matters for San Diego's brief but intense winter rain events where a vented skylight left open during an afternoon downpour creates real damage.

Tile roofs and skylights: the installation challenge most contractors skip

San Diego's tile roof stock makes skylight installation significantly more complex than in shingle markets. A tile skylight install requires: cutting the deck (standard), lifting surrounding tiles without cracking them (requires tile experience), building a proper curb or frame that keeps the tile courses aligned, installing the EDW or ED flashing kit with tile saddles that integrate at the correct height, and refastening the surrounding tile with proper adhesive and mortar at hip, ridge, and eave points disturbed during the work. A contractor who does mainly shingle roofs will struggle with this and skip steps. The most common shortcut is using insufficient saddle depth so tile courses can't properly lap over the flashing, creating a funnel toward the skylight frame. The visual check: from outside, there should be no gap between the tile courses uphill of the skylight and the top flashing. If you can see a gap or sealant-only bridging, the install was compromised. Ask the matched licensed independent roofer whether they do tile skylight work regularly in neighborhoods like Rancho Bernardo, Poway, El Cajon, Chula Vista, and Escondido, where that complexity is normal, and get the kit name, permit, and method in writing.

Interior light shaft: what happens between the roof and your ceiling

Installing a skylight at the roof level is one project. Getting that light into your living space is a second project that many contractors leave to the homeowner. The light shaft is the framed, drywalled, and finished tunnel between the skylight frame in the roof and the ceiling below. Without a light shaft, you have a hole in the roof with a beautiful Velux unit on top and raw insulation visible from inside. Properly constructed light shafts have two configurations: straight (when the skylight sits directly above the target room with no rafters in the way) and angled or splayed (when the light path needs to turn or widen to reach a lower ceiling). Splayed light shafts (wider at the ceiling than at the skylight) significantly increase the light area and reduce the tunnel effect. Drywall finish, tape, texture, and paint matching to surrounding ceiling belongs in the written job scope; a good installer doesn't leave bare drywall or hand off to the homeowner mid-project. Electric and solar skylights also require switch or remote programming, which should be completed before close-out. Ask whether interior shaft work is in the bid or a later add-on, and compare depth, configuration, and finish against that line item before you sign.

What do homeowners ask about Skylight Installation?

How much does skylight installation cost?

Price depends on the unit type, flashing kit, roof material, and whether the interior light shaft is in the quote. Ask for a line-item bid that separates the unit, flashing, interior finish, and any electrical work. Confirm current incentives with that contractor and your tax advisor at quote time.

Why do skylights leak?

A common failure is flashing, not the glass. The kit has to match the roofing material, shingle, tile, or metal, and the counter-flashing has to interleave with the courses above. Ask which kit they will use and whether they currently hold the manufacturer credentials they claim. Do not treat sealant as a flashing kit.

Are skylights worth the cost?

They can be, in the right room. Placement matters: a south-facing unit in a hot room with no shade can add glare and heat. Ask the matched roofer to walk the room, the roof slope, and the interior shaft before you buy.

What about solar-powered vented skylights?

Solar-powered vented units exist for rooms where you do not want a new electrical run. Confirm the model, rain-sensor behavior, and any current utility or tax incentive in writing. This referral brand does not enroll tax credits.

Can you install a skylight in a tile roof?

Yes, when the flashing kit is made for tile and the surrounding tiles are lifted and reset without cracking. Ask the contractor to name the kit and show how it saddles into the tile courses. Tile work usually takes longer than a shingle install because of that handling.
