Skylight installation in Seattle costs $1,500 to $3,500 per unit, depending on type and size. K Single Corp installs VELUX skylights and Sun Tunnels as part of our roofing expertise, ensuring leak-free performance backed by a 10-year workmanship warranty.

Seattle’s overcast skies make natural light a premium feature in any home. A single well-placed skylight can increase room brightness by 30 to 50 percent compared to wall-mounted windows alone. Kitchens, bathrooms, hallways, and stairwells benefit the most, especially in homes where tree cover or neighboring structures limit light from standard windows. During the darker months from November through February, the difference a skylight makes is immediately noticeable.

Common Questions

Frequently Asked Questions

How much does skylight installation cost in Seattle?
Skylight installation in Seattle typically costs $1,500 to $4,000 per skylight, including the unit and installation. A standard fixed VELUX skylight runs $1,500 to $2,500 installed. Venting (operable) skylights cost $2,500 to $4,000 installed. Sun tunnels (tubular skylights) are the most affordable option at $800 to $1,500 installed.
Do skylights leak in Seattle's rain?
When properly installed by experienced roofers, skylights do not leak. Skylight leaks are almost always caused by poor installation, not the skylight itself. K Single Corp installs skylights as part of our roofing work, using manufacturer-specified flashing kits and integration methods that create a watertight seal. We back every installation with our 10-year workmanship warranty.
What type of skylight is best for Seattle?
VELUX skylights with laminated glass are the best choice for Seattle homes. They offer excellent insulation, UV protection, and rain-noise reduction. For rooms where ventilation is desired, venting skylights can be opened to release heat and humidity. Sun tunnels are ideal for small spaces like bathrooms and hallways where a traditional skylight is not practical.
Can you add a skylight to an existing roof?
Yes. Skylights can be added to most existing roofs. The process involves cutting an opening in the roof and ceiling, framing the opening, installing the skylight with proper flashing, and building a light shaft if the attic space separates the roof from the living space. We assess your roof structure to ensure the addition is feasible.
How much natural light does a skylight add?
A single skylight can increase natural light in a room by 30 to 50 percent compared to a standard window. Skylights bring in light from directly overhead, which is more consistent throughout the day than wall-mounted windows. In Seattle, where gray skies are common, skylights make a noticeable difference in interior brightness.
Do skylights improve home value?
Yes. Skylights are considered a desirable feature by home buyers, especially in the Pacific Northwest where natural light is limited during winter months. A well-installed skylight in a kitchen, bathroom, or living area can increase perceived home value and make the space feel significantly larger.
Can you replace my old skylight without replacing the whole roof?
Yes. We replace old, fogged, or leaking skylights without disturbing the rest of your roof. However, if your roof is nearing replacement age, we recommend doing both at the same time. Replacing the skylight during a roof replacement saves labor costs and ensures perfect integration with the new roofing material.
How long do skylights last?
Quality skylights from brands like VELUX last 20 to 30 years. The glass and frame are designed for long-term performance, though seals may need attention over time. If your skylight is older than 15 years and showing signs of fogging, condensation, or leaking, replacement is usually the best option.
