Skylight Installation & Repair in Nora: The Checklist

Skylights are one of those upgrades Nora homeowners either love or regret, and the difference almost always comes down to how the unit was installed and how the surrounding roof was handled. A well flashed skylight on a sound deck can last 20 to 25 years without a drop of water ever reaching your ceiling. A rushed install on a tired roof can start leaking inside the first heavy spring storm, and by then the drywall stains are already spreading.

At Nora Roofer we have been doing roofing work across Central Indiana since 2018, and skylights come up in a lot of conversations. Some folks want more natural light in a dark stairwell. Others inherited an old bubble dome that has been weeping for years and want to know if it can be saved. Our answer is always the same: we will look at it honestly, tell you what we see, and if a repair makes more sense than a replacement, that is what we will recommend.

This Q and A walks through the questions we hear most often from Nora homeowners, from picking the right skylight to understanding why leaks happen and what a proper repair actually involves. No sales pitch, just the information you need to make a smart call on your own roof.

The 7-Point Skylight Checklist for Nora Homeowners

Work through these in order. Most problems fall into one of these buckets.

1. Identify your skylight type
2. Check the age and warranty
3. Inspect the flashing and seal
4. Look for interior warning signs
5. Decide: repair or replace
6. Get the right installer
7. Plan for long-term care

1. Identify Your Skylight Type

Not all skylights behave the same. Knowing what you have changes the repair path.

• Fixed skylights: sealed glass, no opening parts, lowest failure rate
• Vented (manual): open with a crank or pole, good for bathrooms and kitchens
• Vented (electric or solar): motorized, rain sensors, popular in newer Nora builds
• Tubular skylights: small domes that pipe light through a reflective tube
• Custom glass units: larger architectural installs, often on vaulted ceilings

If you cannot tell what you have, snap a photo of the interior frame and the exterior dome or glass. The brand stamp is usually on the inside of the frame near a hinge or corner. VELUX, Wasco, Sun-Tek, and Kennedy are the four we pull parts for most often in Nora.

2. Check the Age and Warranty

Skylight lifespan is shorter than your roof. Plan accordingly.

• Standard acrylic dome: 10 to 15 years
• Glass skylight with proper flashing: 20 to 25 years
• VELUX no-leak glass units: up to 20 years warranty on the glass seal
• Rubber gaskets on vented units: often degrade around year 10
• Flashing kits: should always be replaced when the unit is replaced

If your skylight is older than your roof and you are planning a full roof replacement, replacing the skylight at the same time is almost always the smart call. Tearing into new shingles a year later to swap a failing unit costs more and voids portions of the roof warranty.

3. Inspect the Flashing and Seal

This is where 90% of leaks come from. The glass itself rarely fails.

• Step flashing along the sides, tucked under each shingle course
• Head flashing at the top, diverting water around the unit
• Apron flashing at the bottom
• Counter flashing or cladding that wraps the frame
• Sealant bead between the frame and glass pane

From the ground you cannot see most of this. A proper inspection means a ladder, a roof walk, and eyes on every corner. We offer free skylight and roof inspections across Nora so you are not guessing.

Common flashing mistakes we find on older Nora homes:

• Roofing tar smeared over the seams as a band-aid fix
• Step flashing cut too short and stopping before the head
• Missing ice and water shield under the flashing in valley-adjacent installs
• Shingles laid over the head flashing instead of tucked behind
• Mismatched flashing kits that do not match the skylight frame profile

4. Look for Interior Warning Signs

Before you climb anything, check inside. These are the red flags we hear about most in Nora:

• Brown or yellow staining on the drywall around the skylight shaft
• Peeling paint or bubbling on the interior trim
• Visible water droplets on the inside of the glass after a storm
• A musty smell in the room, especially upstairs bathrooms
• Cracked or separating caulk where the shaft meets the ceiling
• Ice buildup on the frame in January and February

Condensation is not always a leak. If the droplets only show up on cold mornings and disappear by noon, you likely have a ventilation issue rather than a failed seal. Our blog on roof ventilation problems walks through how to tell the difference.

A quick test: wipe the interior glass dry on a clear afternoon, then check it the next morning. If moisture returns without any overnight rain, the house is pushing warm humid air up to a cold pane. Running the bathroom fan longer, adding attic insulation around the shaft, or switching to an insulated glass unit usually solves it.

5. Decide: Repair or Replace

Quick decision matrix.

• Repair makes sense when the unit is under 10 years old, the glass seal is intact, and only the flashing or exterior sealant has failed
• Replace makes sense when the unit is 15 plus years old, the glass is fogged between panes, or you are already replacing the surrounding roof
• Remove and deck over is an option if the skylight is in a bad location (west-facing bedroom that overheats) and you never liked it anyway
• Upgrade from a dome to a modern glass unit if you want better efficiency and UV blocking

6. Get the Right Installer

Skylight work sits at the intersection of carpentry, roofing, and sometimes electrical. The wrong crew causes more problems than they solve.

• Confirm they are a licensed roofing contractor, not a handyman
• Ask for the flashing kit brand and whether it matches the skylight brand
• Verify they carry general liability and workers comp
• Check for manufacturer credentials (Owens Corning Preferred, Malarkey Certified, VELUX installer)
• Read recent reviews from your area, not just the company website

Nora Roofer has been installing and repairing skylights in Central Indiana since 2018, we hold a BBB A+ rating, and we warranty our workmanship separately from the manufacturer warranty on the unit itself.

7. Plan for Long-Term Care

A skylight is not a set-and-forget component. Build it into your seasonal routine.

• Clear leaves and debris from the top and sides every fall
• Check the gasket and sealant every spring
• Clean the glass inside and out twice a year
• Trim branches that drop seeds or sap onto the unit
• After any hail event, have the skylight inspected along with the rest of the roof

Typical Nora Skylight Costs

Ranges we quote on an average Central Indiana project:

• Flashing and sealant repair: $300 to $800
• Gasket or lens replacement: $400 to $1,200
• Single skylight replacement (unit plus flashing kit plus labor): $1,500 to $3,500
• New skylight installation where none existed: $2,500 to $5,000
• Tubular skylight install: $1,000 to $2,200

Storm damage changes the math. Hail can crack domes and dent flashing in ways that qualify for insurance coverage alongside the rest of your roof claim.

Questions Nora Homeowners Ask Us Most

A few that come up on almost every estimate:

• Can I add a skylight to any room? Most rooms with attic space above, yes. Cathedral ceilings are easier. Rooms under an HVAC unit or major plumbing run are harder.
• How long does a replacement take? A single skylight swap with existing framing is usually a one-day job. New cuts add a day for framing and drywall.
• Will it leak? A properly flashed unit with a matched kit should not. The leak rate on our installs over the last five years sits well under 1%.
• What about energy efficiency? Modern low-E glass with argon fill cuts heat gain by roughly 30 to 50% compared to older acrylic domes.
• Do I need a permit? In most Nora jurisdictions, yes, especially if framing is being modified. We pull it as part of the job.

Frequently Asked Questions

How long does a skylight installation take?

A straightforward replacement of an existing Nora skylight usually takes four to six hours. A new opening that requires framing and interior drywall work can run one to two days depending on ceiling access.

Will a new skylight leak?

A properly flashed skylight from a quality manufacturer should not leak for 15 years or more. Nearly every leak Nora Roofer diagnoses traces back to flashing shortcuts, not the unit itself.

Can you replace a skylight without replacing the roof?

Yes. We replace skylights on sound roofs every week in Nora. We tie new flashing into the existing shingle courses and ice and water shield the perimeter.

Why does my skylight drip in winter?

That is usually condensation, not a leak. Warm humid indoor air hits the cold glass and beads up. Better attic ventilation and interior humidity control typically solve it.

Are skylight repairs covered by insurance?

Storm-related damage often is. Age-related seal failure and normal wear are not. Nora Roofer can document the damage during a free inspection and help you decide whether a claim makes sense.
