Cost Guide
Understanding skylight installation costs in Washington DC, Northern Virginia, and Maryland. Fixed, vented, tubular, and custom options with free estimates.
Skylights bring natural light into dark spaces, reduce electricity use, and add value to your home. Costs vary by type, size, and installation complexity.
What Affects Price
Skylight pricing depends on several variables. Here is what determines your total project cost.
Fixed skylights are the most affordable. Vented (operable) skylights cost more due to the opening mechanism.
Larger skylights cost more for both the unit and installation. Standard sizes are more affordable than custom dimensions, which require special ordering.
Double-pane is standard. Triple-pane, Low-E coatings, tinted glass, and impact-resistant glazing improve performance but add to the cost.
Roof pitch, material (asphalt, tile, metal, flat), and structural requirements all affect installation complexity and cost.
If the skylight is not directly under the roof deck, a light shaft must be built through the attic space.
Replacing an existing skylight in the same opening costs less than a new installation, which requires cutting the roof, framing the opening,
