What this solves
Repair the flashing or replace the skylight?
Skylight replacement is the right path once patching an existing roof unit stops holding for long. Fogged panes, yellowed acrylic domes, corroded frames, failed gaskets, and stained drywall usually point to unit or curb failure, not a small flashing gap. The question is not only whether it leaks. It is whether the unit is worth reworking, whether the curb is sound enough to reuse, and whether the new glass should stay like-for-like or move to a better package.

What this solves
Repair the flashing or replace the skylight?
Skylight replacement Sacramento work starts once patching an existing roof unit stops holding. Skylight replacement is the removal of a failing roof unit, repair of the curb beneath it, and the install of new flashing and glazing. Fogged panes, yellowed acrylic domes, corroded frames, and stained drywall usually mean the unit or curb has failed. A flashing gap is a different, smaller problem. In our experience, owners wait one leak too long before they call. On a recent Carmichael roof we found the curb wood soft under two stacked layers of old sealant. As a result, another patch would have failed again by winter. For example, a seal that has already fogged will never reseal itself. Therefore we judge condition first. Then we size the new unit. This page helps you decide when a full swap beats one more repair.
Inspection
What does curb and roof-deck inspection reveal?
Removing the old unit answers the real question: did the leak start at the skylight, the curb, or years of movement around both? A curb is the raised wood frame that lifts a skylight above the roof plane so water drains around it. Once the frame lifts off, we can see curb wood, fasteners, decking, and the order of the flashing. Soft framing, rotted sheathing, and stacked sealant repairs are common on units patched more than once. In fact, a new skylight set on a bad curb only hides the same failure for a season. We measured moisture in the deck on one Folsom job before we quoted the rebuild. As a result, a sound curb keeps pricing simple, while a damaged curb pulls repair into the replacement scope. Specifically, that inspection step protects you from paying twice.
Upgrade
When replacement is the time to upgrade the glass
Replacement is the best chance to leave an outdated skylight behind instead of rebuilding the same weak spot. Insulated glass is a sealed two-pane unit that cuts heat gain and stops the fogging that single panes and acrylic domes develop. Older domes and single-pane units can move to modern insulated glass, better gaskets, and stronger frames. Some owners keep a fixed unit for simplicity. Alternatively, others add a vented unit to release trapped heat. California's Title 24 energy standards shape which glazing package suits a conditioned room. Specifically, upgrade choices belong before fabrication, since the unit type can change curb size and interior trim. So tell us early if the room overheats or the dome fogs. In our experience, that one symptom changes the order more than raw size does. In fact, it often decides fixed versus vented.
Code
Why skylight glass must meet safety glazing rules
Overhead glazing sits above people, so code treats it differently from a wall window. Safety glazing is tempered or laminated glass required in hazardous locations so it breaks safely instead of into sharp shards. Skylights fall under that rule. The federal 16 CFR 1201 safety standard and the California Building Code both govern the glass we set. For instance, many overhead units use laminated glass on the inner pane so nothing falls if it breaks. We install to those rules on every replacement, and we hold CSLB #1115205. On one Roseville tile roof we found the old dome was not rated glass before we ordered the new unit. That single check protects the room below the opening.
What to expect
Skylight replacement Sacramento at a glance
Here is skylight replacement Sacramento at a glance. The job covers unit removal, curb repair, new flashing, and a safety-rated glass package on the existing roof opening. We scope condition first. Specifically, the unit, the curb, the deck, and the roof material all shape the plan and the price. A like-for-like swap is a replacement that reuses a sound curb and matches the old outside dimensions, which keeps most jobs close to one day on the roof. In contrast, tile roofs, curb rebuilds, and drywall repair below add time. For a fast photo review, show the skylight from the roof, the ceiling below, and any staining. Then we tell you whether a repair, a like-for-like swap, or an upgraded unit fits. Call [(916) 720-9009](tel:+19167209009) or send details through our contact form to start.
What to expect
How do we scope a skylight replacement before we quote it?
We scope skylight replacement by checking the failing unit, the curb around it, and the roof system it sits in. The most useful photos show the skylight from the roof, the interior shaft or ceiling below, and any staining or bubbling drywall nearby. Scope and price shift on whether the job can reuse the current opening, whether the curb needs repair, and whether the roofing has to be pulled back carefully on tile. This is also when you decide to stay fixed, upgrade to insulated glass, or switch an older dome to a modern frame. For example, a sound curb keeps the work close to a one-day swap. In contrast, a soft curb pulls carpentry and drywall into the same scope. We measured deck moisture on one Elk Grove job before pricing the rebuild, and that reading changed the plan.

Which page fits if the opening needs a different path?
Start on the right page and the scope questions get easier. Choose skylight installation when you are cutting a new daylight opening rather than replacing a failing unit, because the framing and shaft work differ. The skylight contractor hub compares both paths side by side. Residential glazing fits when the real issue is a standard window or an adjacent panel, not the roof unit. Custom glass helps with a specialty overhead condition. For our license and team, see about us. Capital Glazing serves Rancho Cordova and the 13-city Sacramento metro. That said, most leaking or fogged units belong right here on the replacement path.

FAQ
Questions people ask before calling.
How do I know if my skylight needs replacement or just re-flashing?
Replace the unit if the glass is fogged from seal failure, the frame is corroded, or the curb wood is soft. Re-flashing may be enough when the unit is sound but the flashing was installed wrong. We inspect the unit, curb, and interior staining, then recommend the most practical fix.
Can a new skylight fit the existing curb opening?
Often yes, when the curb is sound and the new unit matches the outside curb dimensions. Manufacturer sizes vary, so a new unit may need a slightly different curb. We measure the existing curb and compare it against current unit specs before we order.
Will skylight replacement damage my ceiling drywall?
The interior trim ring comes off during replacement, so minor drywall touch-up around the shaft is common. If the unit has been leaking, drywall repair or mold remediation may join the scope. We flag any interior damage during the site inspection so nothing is a surprise.
How long does skylight replacement take?
A straightforward like-for-like replacement in a sound curb often finishes in one day on the roof. Curb rebuild, tile roof work, or interior drywall repair add time, and weather affects roof scheduling. We outline the timeline after we inspect the unit and the curb.
What drives skylight replacement cost the most?
Curb condition, roof material, access, and any interior damage move the price more than unit size does. A like-for-like swap into a sound curb on a shingle roof costs far less than a tile job with a curb rebuild. Upgraded glass or vented hardware also adds to the number.
