Skylight installation and repair

A skylight brings daylight into a room, and a skylight that is flashed properly stays dry. We install and repair skylights on shingle and standing seam roofs.

Overview

Skylights in Fredericksburg and Northern Virginia

Skylights are a roof penetration, which makes the flashing around them the most important detail. Leaks that people blame on the skylight itself are often caused by failed flashing or the roof around it.

We install new skylights, replace old ones, and repair skylight leaks. When the roof around the skylight is also at the end of its life, we deal with both at the same time.

Warning signs

Skylight problems we fix

Water around the skylight

Stains or dripping around the frame usually mean the flashing or seal has failed.

Condensation between panes

Fogging between the panes means the seal has failed and the unit may need replacement.

Old units that leak or look worn

Older skylights often leak at the frame and curb.

A new roof is the best time to replace or reflash skylights.

How it works

What to expect, start to finish

  1. Free inspection

    We look at the roof and the areas around it, and talk through what we find before anything is priced.

  2. Estimate

    We confirm the location, size and roof structure, and give you a free estimate.

  3. Installation or repair

    We install or replace the unit and flash it into the roof system.

  4. Leak check

    We check the flashing and finish details before we leave.

Honest considerations

Things worth weighing

  • Placement matters. Skylights on the sunny side can add heat in summer, and the right glazing helps.
  • Cutting a new opening affects framing. We check what is behind the ceiling first.

Questions

Skylights: common questions

Why does my skylight leak?

Often the flashing or the surrounding roof has failed, not the glass itself. We inspect the whole assembly to find the source.

Can you install a skylight on a metal roof?

Yes. Standing seam roofs need skylight flashing designed to work with the seams, and we have installed skylights in them.

Should I replace skylights when I replace my roof?

Often yes. Old skylights are a common leak point, and replacing them while the roof is open is easier and more cost effective.
