How Much Does a Skylight Installation Cost?

Installing a skylight is a great way to add natural sunlight and warmth to any room that does not have a window or where the owner would prefer an alternative solution to save energy. A skylight is essentially a glass window designed to be installed on the roof of a home or building. They come in a variety of shapes, styles, and energy efficiency ratings. Many factors are considered when determining the cost of installation.

Average Prices

Cost of Skylight Installation by Building Type: Home vs. Business

Skylights can be installed above any room in a house, but they are most commonly seen in kitchens and living spaces. Nationally, residential skylights will cost an average of $780 to install. The main factors considered when determining an installation price are the number of stories of the house and the pitch of the roof. The steeper the pitch of the roof, the riskier and harder it will be to install. Skylights on commercials buildings are expected to last longer and be made of a more durable material. It is also common for commercial buildings to have customized, elegant, and large designs which may call for special order skylights that can add to the cost of materials and installation. The roofs on a business or commercial building can also be much higher which will also add to the cost. Expect to pay an average of $806 to have a skylight installed on your business building.


Roofing Material Cost Factors

The type of roofing material on your building has a direct influence on the cost of installing a new skylight. Some types of roofing material may be more difficult to install a skylight on and others may require special skill sets to ensure proper installation. Many manufacturers make their products adaptable to different types of flashings to complement several types of roofing material. On average, installing a skylight on a metal roof will cost you $293. Depending on the pitch of the roof, installation of a skylight on a composition roof can cost you $287. Installing a skylight on wood shake shingles on average can cost $313 for installation. Roofs covered with tar and gravel material are generally flat and are easier to walk, but due to the normal height of these buildings can cost an average rate of $304. A copper roof can add elegance and prestige to any home, but due to the delicacy and high cost of copper material, the national average price rate for installation on this type of system is $1256. Contrary to popular belief, skylights can be installed on a tiled roof, but would require a specialty roofing contractor for a leak proof installation. Not just any roofer can work with cutting and flashing around a tile roof system. The national average rate to install a skylight on this type of system is $408.


Number of Stories Cost Factors

The higher a technician or installer has to climb, the more that can be added to the labor cost associated with installation. A building with one story can be relatively easy to access, a national average rate is $230. A two story building requires a minimum of two people for installation and some special tools which on average can cost $335. Three story buildings definitely require longer ladders which will be difficult for transport and climbing up and down, nationally installation for this scenario can cost $414. Most smaller roofing or installation companies are not equipped with the proper safety tools or insurances to install skylights on a four story building.


Number of Skylights Cost Factors

As with most purchases, the more skylights that a company is contracted for, the lower the price should be for each installation. A couple of installers can install several skylight systems in one day. Expect to pay $197 for the installation of one skylight system, $279 for two skylights, and a national average of $609 for three skylights.


Materials Included vs. Not Included Cost Factors

Materials are available in a wide array of shapes, sizes, and design options. Costs can vary significantly for skylights that can be raised for ventilation and for systems that are more thoroughly insulated. An installation company will measure your existing opening and let you know if your dimensions are standard or will need to be special ordered. Installation companies may be able to offer you special savings due to their relationships with skylight manufacturers. A national average for an installation that includes the skylight and necessary materials is $338 and $232 for an installation without materials.
