Skylight leak repair, done by a roof technician.
Light in. Water out.

Usually, yes. Most skylight leaks start at the flashing and seals around the unit, not the glass — if the unit itself is sound, we reflash and reseal it, published at $850 – $1,400. Glass and frame work isn’t included in that price. If the glass, dome or frame itself looks damaged, we show you photos of what we find and explain it before any work begins — we fix skylight leaks; we don’t sell you a skylight you don’t need.

No. We do skylight leak repair: reflashing and resealing the skylight you already have. We repair roofs — we don’t sell skylights or put in new ones. We’ll look at the leak in person and quote the repair in writing before any work begins.

Skylight reflash & reseal is published in our price book at $850 – $1,400. Anything outside that scope is agreed in writing after review, before any work begins. Contact us for a free repair estimate. We’ll review the issue and explain the next step.

Every job’s warranty terms are written and agreed before work begins — your written terms define exactly what’s covered before you commit. The five-year flashing warranty in our price book covers skylight reflash work.

Caulk can buy time, but sealant breaks down. Skylight flashing is designed to shed water without relying on sealant — which is why we reflash and reseal rather than caulk over the problem.

Short answer: Most often the flashing — the metal work sealing the skylight to the roof — not the skylight glass itself.

• Flashing ages, shifts, and cracks. Once its seal breaks, water follows it inside, usually showing up as a stain below or beside the skylight.
• Other causes: worn seals on the unit, condensation mistaken for a leak (see question 18), or a roofing problem uphill of the skylight.
• A roofer checks the flashing first, then the unit, before saying what it needs.

Short answer: Usually, yes. If the unit is sound and the flashing or seal failed, a reflash and reseal fixes it.

• Reflash and reseal: $850–$1,400, per our price list — new flashing, new seals, tied into the surrounding roofing.
• Glass and frame work isn't included in that price. If the unit itself looks damaged, we show you photos and explain it before any work begins.
• Either way, the surrounding roofing gets checked too — a leak at a skylight can start in the roof around it.

Short answer: Yes — sunlight through the glass adds heat, just like a window. How much depends on the glass, the size, and the room.

• A big south-facing skylight pours in the most sun and heat.
• Glazing choices, shades, and venting skylights change how much heat stays in the room.
• If a room with a skylight is always the hot one, the skylight is a fair suspect — but attic ventilation and insulation play a part too.

Short answer: Usually warm, moist indoor air hitting cold glass — not a leak. The difference matters.

• Condensation: moisture forms on the glass on cold days, then dries. It points at indoor humidity and airflow, not a hole in the roof.
• A leak: water stains, drips, or puddles that don't dry up, often after rain rather than on cold clear days.
• If you're unsure which one it is, note when it appears and tell a roofer — the pattern says a lot.

Short answer: Reflash and reseal runs $850–$1,400.

• The reflash/reseal range covers new flashing and seals tied into the existing roofing.
• Anything outside that scope is priced per job, after a look — no honest flat number exists without seeing it.
• Either way, you get the scope and the price before work begins. Nothing extra gets added without your agreement.

Short answer: No — skylight leak repair is roof-side work that ties into your existing roofing.

• The flashing gets reworked and woven into the shingles already there.
• If the roofing right around the skylight is shot, that section gets addressed as part of the job — but the whole roof doesn't need to come off for one skylight.
• A roofer checks the curb flashing and the membrane around it first — that's where skylight leaks start.

Short answer: Snow piling behind the skylight's raised curb can melt and pool at the flashing — a winter leak with no rain at all.

• House heat melts the snow sitting against the upper side of the curb. The meltwater can't drain over the frozen roof below, so it sits against the flashing seams and pushes in.
• It shows up as stains beside or below the skylight, often after a thaw rather than during a storm.
• A roofer checks the curb flashing and the membrane around it — that's where winter skylight leaks start.
