Skylights wear out. Seals fail and the glass fogs, frames crack, and flashing that has been patched a few times stops keeping water out. An old skylight can also be drafty, letting heat escape in winter and pour in during summer. At some point, replacing the unit makes more sense than fixing it again.

Home Crew Construction handles skylight replacement on Long Island for homes in Nassau County and Suffolk County. We remove the old unit, check the framing and roof around it, and install a new skylight with new flashing tied into your shingles. It’s one of our skylight services.

Quick answer: When should a skylight be replaced?

Replace a skylight when the glass is fogged between the panes, the frame is cracked or rotting, it keeps leaking after repairs, or you’re replacing the roof. Home Crew Construction replaces skylights across Nassau and Suffolk County on Long Island with new units and new flashing tied into the roof.

How it works

How a skylight stays dry.

Most skylight leaks come from the flashing around the frame, not the glass. Here is how the pieces go together.

Illustration. Point at a part to see what it does.

UnderlaymentSkylightsA water-resistant layer on the deck, turned up the sides of the frame under the flashing.
FrameThe box that sets the skylight on the roof and brings the light down into the room.
GlassThe glazed panel. Fogged or cracked glass usually means the unit is due for replacement.
FlashingSkylight repairSeals the frame to the roof. Failed flashing is the usual cause of a skylight leak.

Types of skylights we install

Fixed skylights: light without ventilation. Simple and low-maintenance.
Venting skylights: open by hand or with a motor to let out heat and moisture. Good for kitchens and bathrooms.
Tubular skylights: a compact option for hallways, closets and small bathrooms.
Custom skylights: for unusual spaces or specific design needs.

Replacement is also a chance to upgrade. Swapping a fixed skylight for a venting one in a bathroom helps clear out moisture, and newer glass generally insulates better than the skylights installed decades ago.

Should you replace skylights with a new roof?

In most cases, yes. When the roof is replaced, the shingles around the skylight come off anyway, so it’s the easiest time to put in a new unit and flash it into the new roof. An old skylight left in a new roof may need replacing a few years later, which means cutting into brand-new shingles.

We can replace skylights as part of a roof replacement. The new roof itself comes with our 10-year labor warranty and a lifetime manufacturer warranty.

What affects the cost of skylight replacement?

Every skylight job is priced after we see it. The main factors are:

The type and size of the new skylight
Whether the opening has to be resized and reframed
The pitch of the roof and how easy it is to reach
Any water damage to the framing or roof deck
Whether the work is done on its own or with a roof replacement

Skylight replacement FAQ

Common questions.

Still not sure?

Call 631-965-0881 any time. We'll tell you straight whether it's a repair or a replacement.

Can skylights be added when you replace my roof?

Yes. Replacing the roof is the ideal time to add a skylight, and we can install it as part of the same job.

Why is there fog between the panes of my skylight?

Fog between the panes means the seal around the insulated glass has failed. It can’t be wiped away, so the glass or the whole unit needs replacing.

Can I change the size of my skylight when I replace it?

Yes. Going bigger or smaller means reframing the opening in the roof, which adds some work. We’ll explain what’s involved when we quote the job.

What types of skylights do you install?

Fixed, venting and tubular skylights, plus custom units for unusual spaces.
