No curb
Units installed flush into the roof surface have nowhere for water to go but in. The correct detail raises the unit above the water plane.
Skylights leak for one reason nine times out of ten: the flashing and curb detail around them. The unit itself is rarely the culprit.

A well-installed skylight brings light into a space that would otherwise need electricity during the day, and on the roof it is a penetration like any other — which is exactly how it should be detailed.
We install new units on properly built curbs with correct flashing, replace failed or fogged units, and repair leaks caused by curb rot, inadequate flashing, deteriorated sealant or condensation that was misdiagnosed as a leak.
Skylight work includes new installation (fixed, vented, or tube), replacement of failed units, curb construction and re-flashing, and repair of leaks. A skylight should sit on a raised curb flashed into the roof system, not bedded into sealant.
| Option | What it is | Relative cost |
|---|---|---|
| Fixed skylight | Non-opening unit for daylight only. Least likely to leak, lowest cost. | low |
| Vented skylight | Opening unit for ventilation as well as daylight. | mid |
| Tubular skylight | Small-diameter light pipe for hallways, closets and bathrooms where a full skylight will not fit. | low to mid |
| Unit replacement | Swapping a failed unit on an existing sound curb, which is cheaper than a new installation. | mid |
The same sequence every time, because it is the sequence that protects you: evidence first, price second, work third, documentation last.
Determine whether the problem is flashing, curb rot, glazing failure or condensation.
Unit type, size and glazing matched to the room and the roof orientation.
Curb built, membrane and flashings detailed, unit installed and sealed to spec.
Interior trim and drywall made good, with advice on ventilation to prevent condensation.
These are the failure patterns we are called in to correct most often — usually after someone else was paid to do it once already. Knowing them is the best protection you have when comparing quotes.
Units installed flush into the roof surface have nowhere for water to go but in. The correct detail raises the unit above the water plane.
Sealant has a service life of a few years, and skylight leaks are the classic result of relying on it.
Warm moist interior air meeting a cold pane produces water that looks exactly like a leak. Adding ventilation or using the right glazing is the fix.
When a skylight has leaked for years, the curb itself is often soft. Replacing the unit on a rotten curb simply moves the leak.
A new fixed skylight installed with a properly built and flashed curb typically runs from about $1,500 to $4,500 depending on unit size, roof pitch and interior finishing. Replacement of a unit on an existing sound curb is usually cheaper, and leak repairs caused by flashing details generally fall in the repair price range.
Because a skylight is a hole in the roof, and the way it is flashed is the whole story. We build the curb, detail the membrane and photograph the finished flashing — and we tell you honestly when what you have is condensation rather than a leak.
Crews are dispatched to Lakeway, Texas and the surrounding communities through our network of licensed, insured roofing contractors, with dispatch priority published for every market we cover. That means small towns get a real crew instead of a three-week wait or no quote at all — the trade-off is that some extended-coverage areas are served on a rotating route, and the dispatcher will tell you honestly which one your address is in.
Lakeway is one of hundreds of markets where we run this work, and every one of them has its own page listing covered ZIP codes, local roof stock, climate pressures and the neighbouring areas we also serve.
Prefer to start from the state? Each page below covers skylights locally — what the work involves in that climate, what the local roof stock looks like and which cities we serve there.
Everything below is handled by the same crews. Contextual links, not a keyword list — pick whichever one describes your problem.
A skylight installed by a roofing contractor with the manufacturer’s flashing kits, documented in the roof’s warranty file, is generally acceptable. What causes warranty problems is a unit installed by another trade without roofing documentation.
Often yes — if the unit itself is sound and the curb is solid, re-flashing and correct membrane detailing solves it. If the curb has rotted or the seals have failed, replacement is the honest answer.
Condensation, usually. Warm humid interior air condenses on the cold pane. Better interior ventilation, or a unit with improved thermal glazing and a thermal break frame, addresses it. A leak, by contrast, tends to show up during rain rather than during cold weather.
Yes — Lakeway is inside our coverage area and crews are routed to that market on a published dispatch priority. Call (858) 779-8014 and the dispatcher will confirm scheduling for your address and give you a realistic window rather than a marketing one.
A new fixed skylight installed with a properly built and flashed curb typically runs from about $1,500 to $4,500 depending on unit size, roof pitch and interior finishing. You get a written price before any work starts, and anything discovered mid-job is priced, photographed and approved by you rather than added to an invoice at the end.
One call gets you a real answer: whether what you are describing is skylights work, what it is likely to cost in Lakeway, and how soon a crew can be at your address.
