Skylight Installation

Skylight installation across the Springfield area. Curb and deck-mount units flashed into the roof the right way, so you get daylight without the leaks.

Skylight Installation in Springfield

Done right, a skylight changes a room more than any light fixture can. Done wrong, it’s a hole in your roof with a window in it. Summit Roofing installs and replaces skylights across the Springfield area, and we treat the flashing, not the glass, as the real job. Family-owned since 1985, licensed roofing contractors on every crew.

Curb-Mount or Deck-Mount

Curb-mount units cap a framed wooden box that lifts the skylight above the roof plane. The curb gets flashed like a small chimney, and future replacement is simple: lift off the old lid, set the new one. It’s the right call on low-slope sections and anywhere a curb already exists.

Deck-mount units screw directly to the roof deck through an integrated flange and sit low against the shingles. They’re the cleaner look on most pitched roofs, and the factory flashing kits (one version for shingles, others for metal and high-profile roofing) weave the unit into the roof course by course.

We install both, and we’ll tell you which one your roof actually calls for.

Flashing Is the Whole Job

Water never stops at the top of a skylight. It splits and runs around it, and the flashing manages that path: ice and water shield wrapped around the opening, step flashing woven into each shingle course up the sides, a head flashing at the top, and a sill flashing kicking water back onto the field at the bottom.

Notice what’s not on that list: caulk and tar. Sealant on a skylight is a one-year patch, and a unit buried under a bucket of tar is the most common mess our leak repair crews inherit. The same flashing principles that keep a chimney dry keep a skylight dry, and there are no shortcuts in either case.

The Best Time: During a Reroof

If your roof is due for replacement, that’s the day to deal with skylights. Old units come out with the old shingles, new units flash into the new roof as it’s built, and you never pay twice to disturb the same section. Skylight manufacturers recommend exactly this: replace the units whenever the roofing around them is replaced, so the whole assembly ages on the same clock.

Building new? Skylights planned during framing cost the least of all. We handle them as part of new construction roofing.

Drip in Winter? Probably Condensation

A skylight that drips on cold mornings with no rain in sight isn’t leaking, it’s sweating. Warm room air condenses on cold glass the same way a cold drink sweats in July. Modern double-pane units cut that condensation dramatically, and better airflow in the room handles the rest.

If water shows up during rain or snowmelt, that’s a different story. A roof inspection will find the entry point, which is usually the flashing or the surrounding shingles rather than the skylight itself.

Frequently Asked Questions

Do skylights always end up leaking?
No. A skylight flashed with the manufacturer's kit into sound roofing doesn't leak. The bad reputation comes from old units sealed with roofing tar instead of flashing, and from skylights that outlived the roof around them. Flash it right and it's as dry as any other part of the roof.
What's the difference between curb-mount and deck-mount skylights?
A curb-mount skylight sits on a framed box (the curb) that raises it above the roof surface, and the unit caps the box like a lid. A deck-mount skylight fastens directly to the roof deck and sits lower and sleeker. Curb-mount is the standard on low slopes and existing curbs; deck-mount is the cleaner look on most shingle roofs.
Should I replace skylights when I replace the roof?
Yes, almost always. A 20-year-old skylight reflashed into a brand-new roof is the next leak waiting to happen, and swapping it later means tearing into finished roofing. New units installed during a roof replacement cost far less than the same work done separately.
Can you add a skylight to my existing roof?
Yes. We cut the opening between rafters, frame it, and flash the unit into the surrounding shingles with the manufacturer's kit, and your drywall contractor finishes the light shaft inside. Most installs take a single day on the roof side.
Why does my skylight drip when it hasn't rained?
That's condensation, not a leak. Warm indoor air hits the cold glass and the moisture beads up, usually in winter, usually on older single-pane or seal-failed units. A modern double-pane unit and better airflow in the room solve it. A true leak shows up during or right after rain.
