Skylight cleaning cost

Window cleaning prices are $10 to $35 per skylight for sizes up to 30 square feet, or $1.50 to $2.50 per square foot. Fees vary depending on the accessibility, total number of windows cleaned, and whether it’s part of a full roof cleaning service.

Cost factors to repair or replace a skylight

The following factors affect the cost for a skylight repair or replacement:

  • Accessibility – The roof height, slope, and ease-of-access determine the total labor charges.
  • Timing – Skylight labor costs are cheaper when reroofing than as a standalone replacement.
  • Labor – Hourly costs are higher than average in metropolitan areas, for emergency service, and for complex installations.
  • Glass type – Prices to replace the glass vary for types like uninsulated single-pane glass, double-pane glass, triple-pane glass, or tempered glass with a UV-reflective coating.
  • Framing a chase tunnel – Repairing a skylight shaft may include installing new wood studs, drywall, and repainting the shaft interior.
  • Size & type – Small tubular skylights are cheaper than most other glass skylights.
  • Permits – A permit costs $100 to $500 depending on whether it’s a repair or replacement.
  • Insurance – Homeowners insurance may cover repairs or replacements due to extreme weather events.
  • Warranty – Units covered by a manufacturer’s warranty may get free repairs.
  • Rebates and tax credits – Upgrading to energy-efficient or solar-powered skylights qualifies for a 26% to 30% federal tax credit and local rebates.
  • Upgrades – Adding blinds or remote-control openers increases the total cost.
  • Roof modifications – Replacing existing skylights with a larger model requires modifying the roof opening and more flashing, which increases the labor cost.

  • The labor cost to repair a skylight is $30 to $80 per hour on average.
  • Roof work labor costs $150 to $300 minimum in call-out fees.

Frequently asked questions

How long does it take to replace a skylight?

Replacing a skylight takes 3 to 5 hours on average, depending on the size, model, roof type, and accessibility. Labor time increases for additional ceiling painting and trim fixing.

How often should skylights be replaced?

Skylights need replacing every 15 to 40 years on average, depending on the type, brand, and installation quality. Most companies recommend replacing the unit after 30 years to keep up with new building codes and skylight technology.

Should I replace skylights when reroofing?

Replacing a skylight when reroofing has these advantages:

  • Labor costs per skylight are cheaper when reroofing.
  • Get new skylight designs & the highest energy-efficient glass.
  • Receive a warranty for the roof & skylights, typically for 20 to 30 years.

However, the cost to reroof a house is $4,700 to $10,500, excluding skylights. Homeowners who reuse old skylights in a new roof typically void the skylight’s warranty.
