Skylight replacement in Sioux Falls
A skylight that leaks, fogs between the panes or is as old as the roof is worth a look before the shingles come off. Here is how to read the signs, what glass to ask for in hail country, and what replacement costs.
Is my skylight leaking, or is it condensation?
Look at where the water is. One skylight maker says streaks of condensation between the panes, still there after cleaning, mean the seal has failed and the unit may need replacing.
Drips or frost on the room side are a different problem. Warm, damp indoor air meets the cold glass and condenses. The maker calls that a humidity issue, and in a Sioux Falls winter the same damp air can frost the attic too. See winter leaks and attic frost.
Water around the frame, or a stain on the ceiling beside it, needs tracing from the roof side before anyone patches the ceiling. Start with where flashing leaks start.
Should I replace my skylight when I get a new roof?
One skylight maker recommends it. That maker says the average skylight lasts 20 to 30 years, and that its 20 year product warranty can line up with a 20 year roof warranty.
A remodeler who installs that brand says taking off the shingles around an old skylight later costs more, and recommends replacing skylights with the roof every time. Both are sellers.
If your skylight is close to the age of your roof, ask for a price on both in one quote, and read what happens on replacement day.
Can hail break a skylight?
It can, and the glass you choose decides what the warranty does about it.
One skylight maker gives its laminated glass a 10 year hail warranty on double and triple pane units. You have to show that hail broke the glass, and the National Weather Service has to confirm the storm. Its toughest option, impact glass, meets the wind-borne debris rules in the model building codes.
Glass skylights carry no UL 2218 or FM 4473 hail rating that we could find. Those are the tests behind Class 4 shingles. One maker of tubular skylights does post a 2023 FM 4473 lab report: its dome took 2 inch ice balls without cracking. So ask for laminated or impact glass by name, and write down the date of any storm that cracks it. Here is what the Class 4 tests measure, and the dated list of Sioux Falls storms.
What does skylight replacement cost?
Most national figures land between about $1,000 and $2,800 installed. We found no Sioux Falls price.

Is there a tax credit for a new skylight?
Not for one put in now. The federal 25C credit ended for skylights placed in service after 31 December 2025, according to third-party summaries. We did not read the IRS notice, so confirm with your tax preparer.
A 2025 install could still qualify. The credit was 30 percent of the cost, labor excluded, capped at $600 a year for windows and skylights combined, and the skylight had to meet ENERGY STAR Most Efficient rules. It is claimed on Form 5695.
Do I need a permit to replace a skylight in Sioux Falls?
Unconfirmed. The city’s 2024 announcement of its roofing license said building permits cover work including shingle and roof repairs. One permit website says structural roof changes, skylights included, need a building permit. It is not a city source.
Call Sioux Falls Building Services at 605-367-8670 before work starts, and check the roofer’s city license.
