Flashing and curb leaks
Re-sealing alone rarely lasts if the flashing was installed wrong or has rusted, loosened, or separated. We inspect the curb, step flashing, counterflashing, and how it ties into the roofing and underlayment.

Find the real failure point
Skylight leaks usually aren't the glass
If you're searching for calgary skylight repair, you're probably dealing with water staining on drywall, a dripping frame during a melt, or a cold draft that shows up every time the wind kicks up. In a lot of cases, the skylight itself isn't the only issue. The leak path is often the flashing system, the seal at the curb, aging shingles right around the opening, or condensation that's being mistaken for a roof leak.
Our team at Calgary Roof Inspection approaches skylight repair the same way we approach any roof leak: confirm the source before proposing work. A skylight opening is a roof penetration, so small errors in step flashing, underlayment tie-ins, or fastener sealing can let water travel and show up far from where it started.
In Calgary, freeze-thaw swings and wind-driven precipitation can expose weak points quickly. A repair that holds in mild weather can fail when meltwater backs up, ice forms near the curb, or gusts push water where gravity alone normally wouldn't. The goal is a repair that matches your roof assembly and handles real conditions, not a temporary patch.
Common failure points
What we fix during skylight repair in Calgary
Cracked or failed glazing seals
If the glass is cracked or the insulated glass seal has failed, you can see persistent fogging or moisture between panes. We confirm whether the unit can be repaired or if replacement parts are needed.
Drafts and cold spots
Drafts can come from gaps at the interior trim, the shaft, or an uninsulated chase, but they can also be an exterior air leak at the frame or curb. We check both sides so you don't pay to fix the wrong thing.
Interior staining and bubbling drywall
Water marks around a skylight can be active leakage, condensation, or past damage. We look for current moisture pathways and document what's still wet versus what's old.
Recurring leaks after past patching
Tar, roof cement, and heavy caulking can hide the problem for a season and then crack. We identify where the assembly is failing so the repair addresses the cause, not the symptom.
Inspection before repair
How we diagnose a skylight problem (before any repair)
Skylight repair Calgary homeowners can count on starts with inspection, not guesswork. We typically begin by checking the roof area around the skylight, because water often enters upslope and travels along decking or rafters before it shows inside.
During the visit, we look at:
- Roof covering condition around the unit, including shingles, fasteners, granule loss, and lifted tabs
- Flashing details at the sides and head, plus the sill area where water needs to drain cleanly
- Underlayment tie-in at the curb and any signs of past re-work
- The skylight frame, glazing, and perimeter seals
- Interior signs that point to condensation versus exterior water entry, especially in winter
You'll get a clear explanation of what we found and what a lasting fix would involve. If the skylight is near the end of its service life, we'll tell you that too, because some repairs are false economy. If you're comparing providers, it helps to start with a team that does roof inspection work every day and can trace moisture paths without jumping straight to replacement.

-
01
Book an on-site assessment
We confirm the symptoms, roof access, and safety requirements, then schedule an inspection that fits the weather window. Skylight issues can worsen quickly, so earlier diagnosis usually reduces the scope.
-
02
Pinpoint the entry point and failure mode
We check the skylight, the flashing system, and the surrounding roof field. Where appropriate, we also review the interior finish for signs of condensation or air leakage that can mimic a roof leak.
-
03
Provide a written scope with options
Some cases need a targeted flashing repair; others call for re-working the curb area or addressing nearby roofing materials. We explain the tradeoffs so you can choose based on durability and budget.
-
04
Complete the repair and tidy up
Repairs are done with attention to water-shedding details: proper layering, sealing where it belongs, and keeping drainage paths open. We finish with a visual check of the repair area and a clean work site.
Calgary repair pricing
How Much Does Calgary Skylight Repair Cost in Calgary?
Most calgary skylight repair work typically ranges from about $350 to $1,200+, depending on whether it's a minor seal or flashing correction versus a more involved curb or surrounding roof repair. If the skylight unit or insulated glass has failed, costs can be higher because parts and labor move closer to replacement territory.
Final pricing depends on roof pitch and access, roof type (asphalt shingle versus other systems), how far the leak has travelled, the condition of surrounding materials, and whether interior finishing has been affected. The exact cost is confirmed after the on-site inspection and a written scope.

Common questions
Calgary skylight repair FAQs
How do I know if I need skylight repair or full skylight replacement?
You usually need repair when the problem is flashing, curb sealing, or nearby roof materials, and replacement when the glazing is cracked or the insulated glass seal has failed (fogging or moisture between panes that won't clear). We confirm which it is by inspecting both the roof-side water-shedding details and the skylight unit itself, because the symptoms can look the same from inside.
Why does my skylight leak during snowmelt but not during rain?
Snowmelt leaks often point to slow-moving water that can back up around the curb or find tiny gaps in flashing layers, especially during freeze-thaw cycles. In Calgary, temperature swings can open and close small separations in sealant or flashing joints, so a skylight can stay dry in a short rain but leak when meltwater sits and refreezes.
Can you fix a skylight leak without redoing the surrounding shingles?
Sometimes, yes, but only if the flashing system can be accessed and corrected without damaging or compromising the surrounding roof covering. If shingles around the skylight are brittle, poorly sealed, or already disturbed by past patching, a proper repair often includes lifting or replacing a limited area so the flashing and underlayment layers can be tied in correctly.
Is caulking around a skylight a real repair?
Caulking can be part of a repair in the right locations, but it is rarely the whole fix for a roof-side leak. A skylight opening relies on water-shedding layers (flashing and underlayment) more than surface sealant, and heavy exterior caulking can crack with UV exposure and temperature changes or trap water where it should drain.
What causes drafts around a skylight in winter?
Drafts can come from gaps at the skylight frame, an air leak at the curb, or issues inside the light shaft such as missing insulation or air sealing. Because Calgary winters make these problems obvious fast, we check both exterior and interior conditions so you're not paying for a roof repair when the issue is actually air movement through the ceiling assembly.
How long does skylight repair usually take?
Many repairs can be completed in a single visit once the scope is confirmed, but timing depends on roof access, the type of repair, and weather windows. If materials around the skylight need partial re-work, we'll outline what can be completed immediately versus what should wait for safe, dry conditions.
