VELUX · HOMEOWNER PRODUCT & INSTALLATION GUIDE
Choose how you want your room to feel. Then match the skylight, shade and installation to your home.
Explore VELUX’s current product families and the details that matter before you replace a skylight or create a new opening.
Official sources reviewed September 14, 2026
01 · CHOOSE YOUR DAYLIGHT
Start with the room and how you will use it. The suggestions below are Cross + Crown planning guidance; final suitability comes from the roof and room inspection.
The current residential Skylight System combines the skylight with a factory installed shade and remote. Flashing is selected for the roof and mounting method. Confirm the exact package in your proposal; Sun Tunnel, roof window and custom products have their own configurations. VELUX system overview
| Your option | How it works | Planning consideration |
|---|---|---|
| FixedDaylight | Stays closed. A powered shade can adjust the light without opening the skylight. | Consider when you want daylight and already have adequate room ventilation. |
| Manual Fresh AirDaylight + ventilation | Opens with a handle or compatible operating rod. | Plan how you will reach it and close it when rain approaches. The shade and skylight operate separately. |
| Solar Powered Fresh AirDaylight + ventilation | A solar charged battery powers the opening motor. Remote operation and a rain sensor are included. | Useful for openings that are difficult to reach. Confirm solar exposure, controls and the selected model. |
| Electric Fresh AirDaylight + ventilation | Uses the home’s electricity, with remote operation and a rain sensor. | Include electrical supply and wiring in the scope. Discuss operation during a power outage. |

SMALL SPACES
A roof collector brings daylight through a reflective tube to a ceiling diffuser. Consider hallways, closets, bathrooms and interior rooms where a full light shaft is impractical.
Rigid tubing suits a more direct route; flexible tubing can route around obstructions. Rigid elbows are also available. Roof pitch, tube route and distance affect the selection. A Sun Tunnel provides daylight rather than an opening for fresh air.
Explore Sun Tunnel skylightsLOW ROOF PITCH
VELUX lists curved glass, fixed flat roof, roof access, double dome acrylic and TCR Sun Tunnel options in this family.
Select the exact product for the measured slope, roof covering, curb and drainage. A product being described as suitable for a flat roof does not make every flashing kit suitable.
Explore flat roof productsWITHIN REACH
Designed for reachable sloped ceilings in lofts, attics and bonus rooms. Choices include center pivot, top hinged, roof balcony and roof access windows.
These are distinct from overhead skylights. Any proposed emergency escape or roof access use needs the exact opening, installation and local requirements checked.
Explore roof windowsCUSTOM DESIGN
Custom metal framed designs with choices in shape, finish and glazing. Configurations include square, octagonal and extended pyramids, single and double pitch, structural ridge and low profile systems.
These need a project specific design and scope.
Explore Architectural SeriesLARGER BUILDINGS
Engineered modules for commercial daylighting, including Longlight, wall mounted Longlight, Northlight, Ridgelight and stepped configurations.
Structural support, roof interfaces and controls require design coordination before an installation commitment.
Explore modular systemsLARGER OPENINGS
Expanded glass areas, custom sizes and finish choices for openings beyond standard residential units. VELUX lists laminated LowE³ glass with additional glazing options.
Review dimensions, structure, access and the separate product terms during design.

VELUX says its current Skylight Systems include a white solar powered room darkening shade. Other colors and styles are ordered separately. Confirm compatibility for older units and products outside this system range.
Room darkening is useful for bedrooms and screen glare. Discuss other shade styles when softer daylight is the priority. A solar powered shade does not mean the skylight itself opens with solar power.
VELUX Touch operates compatible skylights and shades. VELUX ACTIVE adds a gateway, sensors, an app and a departure switch, with monitoring for temperature, humidity and CO₂.
ACTIVE is an upgrade. Confirm product compatibility, the internet connection and what controls your package includes before ordering.
Sun Tunnel options include decorative diffusers, a daylight controller, an electric light kit for nighttime use, extension tubes, elbows and roof specific flashing. Confirm which fit your unit.
Roof window accessories include compatible manual shades and insect screens.
VELUX lists standard safety glass and selected impact, snow load, white laminated and tempered glass options. The appropriate choice depends on the product, room and location.
Compare the exact unit’s glass specification and performance label. Shade performance figures are not a prediction of whole home utility savings, and one product’s certification does not apply to every model.

03 · THE CONNECTION TO YOUR ROOF
The mount determines how the unit attaches. The flashing directs water around it and into the surrounding roof system.
Fastens directly to the roof deck for a lower profile. Roof pitch, opening size and the specified flashing determine suitability.
Fits over a raised framed curb. On a replacement, check the curb’s dimensions, height, condition and waterproofing before assuming it can remain.
Has integrated flashing. It is a separate configuration with its own roof and installation limits, rather than a universal replacement for a flashing kit.
VELUX mounting and flashing overview
THREE LAYERS WORK TOGETHER
| Roof covering | Deck mounted | Curb mounted |
|---|---|---|
| Shingles or shakes | EDL | ECL |
| Tile | EDW | ECW |
| Metal | EDM, where the panel profile qualifies | Project specific detail |
These are product families, not ordering instructions. Match the model, size code, roof material and permitted pitch range in the exact installation manual. A skylight’s allowable slope may differ from its flashing kit’s allowable slope. Low slope membranes and unusual roof profiles need their own approved details.

04 · FROM ROOM TO ROOF
This is a homeowner planning guide. The selected product’s current installation instructions control the field work.
Review daylight goals, ceiling height, framing, obstacles, roof pitch, roofing material and access. With a flat ceiling, a finished light shaft may be needed through the attic.
Record the product, dimensions, glass, mount, shade, controls and flashing. Identify any framing, electrical work, interior finishing and required approvals.
Plan weather protection and access. Prepare the opening or curb, install the specified underlayment and flashing, and restore the surrounding roof covering.
Complete the agreed shaft, insulation, air sealing, drywall, trim and painting. Check operation and controls, clean up and review the finished work with you.
Planning reference: VELUX installation process. Cross + Crown’s written scope identifies the work included on your project.
VELUX describes a new installation as roughly half a day to three days depending on conditions, while a straightforward single replacement may take a few hours. Weather, repairs, shaft work and finish visits can extend the schedule.
Product choice, quantity, roof access, framing, wiring and interior finishing affect the price. Manufacturer estimates are planning ranges. Your Cross + Crown proposal establishes the scope and price for your home.
05 · REPAIR OR REPLACE
Water around a skylight can come from the unit, flashing, nearby roofing or condensation. Cross + Crown inspects accessible conditions and explains whether a repair is practical or replacement deserves consideration.
Review existing skylights at the same time. Age, glass condition, controls, flashing and the surrounding curb or deck all matter. Do not assume old flashing can simply be reused.
The current VELUX written warranty excludes certain leaks after reroofing without the specified new underlayment wrapping and approved flashing. Confirm the requirements for your existing unit.
VELUX replacement guidance · Written warranty, section 3.1.7
Photograph the identification label and record the full model, size and production code. Measure the roof opening or curb as required by the selected unit’s instructions, not only the visible glass.
Check flashing and shade compatibility, the interior opening and any repair or trim changes. A similar appearance does not establish an exact replacement.
06 · PROTECT YOUR INVESTMENT
Manufacturer coverage and contractor workmanship coverage are separate. Your proposal identifies Cross + Crown’s workmanship terms.
| Coverage | Period | What to verify |
|---|---|---|
| Insulating glass seal | 20 years | Specified unit skylight models and qualifying internal seal failure. |
| Product defects | 10 years | Applicable glass skylights, roof windows and flashings. Other products can differ. |
| Shades and controls | 5 years | Covered components and defects. |
| No leak installation | 10 years | Listed skylight and flashing combinations, qualifying residential roof conditions and installation strictly to the instructions. |
Read the VELUX limited warranty effective May 1, 2026 (PDF), which applies to qualifying U.S. purchases from that date. Earlier purchases require their applicable terms. This table is a selection, not every product’s coverage.
Condensation is excluded. Hail coverage is limited to specified products and conditions. Labor, removal, reinstallation and other expenses have exclusions or limits. Sun Tunnel, dome, flat roof and commercial products have separate provisions. Keep the invoice, model details and installation records.
Use a soft cloth and water or an appropriate mild cleaner on glass. Wet the surface first and avoid abrasive tools. Keep accessible drainage areas clear and arrange professional roof access where needed.
Manage indoor humidity and ventilation if condensation appears. Follow the unit’s instructions for finishes and moving parts.
Photograph the condition safely, note when it occurs and contact your installer. Have the product label, purchase information and installation date ready. Avoid unauthorized modifications while a warranty concern is being reviewed.
