A skylight is a special kind of window built into a house roof to allow natural light to come in. A skylight may be installed for aesthetic purposes or as part of a passive heating strategy.

Types of Skylights

There are three main types of skylights (also called roof windows): fixed, ventilating and tubular.
Fixed skylights are skylights that do not open. They are installed for the purpose of providing additional light only. Fixed skylights are the most popular types of skylights.
Ventilating skylights are skylights that can be opened and are best for kitchens or bathrooms, where they help remove excess moisture and keep a steady flow of air. They can be operated by a remote control, a manual or motorized hand crank, or by sensor-controlled thermostat. These are the most expensive type.
Tubular skylights are the newest type on the market. They are small, circular-shaped skylights typically installed in small rooms, hallways and closets. They are normally 10" or 14" in diameter. Tubular skylights can significantly decrease your energy costs by eliminating the need for electric lights during the daytime

Skylight Size

If you choose the wrong type of skylight for your space, it could either be too small and not function correctly or too large with air escaping or rain leakage. Details are extremely important for skylight installation. The opening in the roof and ceiling must be precisely aligned. If they are misaligned, the skylight will not fit into the spot, and the mistake will require more time and money to correct.

Noise Reduction

The least expensive skylights are single-paned and provide the least amount of insulation from outside noises. If you're sensitive to sound, double- or triple-paned skylights will be the better choice for you. Also, skylights that don't open or operated by remote or thermostat tend to be quieter than ones with a motorized hand crank. So, consider spending a bit of extra money upfront in order to save you problems down the road.

Increased Energy Efficiency

Skylights are great for adding light to dark rooms and cutting back on electricity use from lamps, but skylights also can allow heat to escape from a home or let cold air in. The most effective way to make skylights efficient is to have double-pane glass and several coats of insulating glaze. Also, consider adding a skylight shade as that will help reduce energy loss. You can use them to prevent unwanted heat during the day if desired.

I like that I could read about the product, estimate the cost and make my own decision as to who I want to work with without any pressure.  I can get in touch when I chose to, great information, thank you.

Does this estimate for installing a skylight include the price of the skylight or just the labor?

I like the fact that you can get a price range estimate before you have a pro come to give a fixed quote. This is a great tool

I didn't like the fact that I could not ascertain whether anyone would call me to make an appointment to view the project.
