Skylights are means of bringing essential natural light into a space that would otherwise have none. Major industry trade associations rank the installation of a skylight as one of the most cost-effective improvements a homeowner can undertake.
Many consumers fear leaks, condensation, heat gain, disruption and cost.
Although a high-quality skylight properly installed is not likely to leak, the other issues expressed are legitimate concerns.
Typically, the installed cost of an average skylight will range between $2,500 and $4,500. The job can take a day or two to several weeks to complete.
An easier, cheaper answer is the tubular type. It consists of an acrylic dome that sends natural light through a highly polished mirrorlike tube, either 10 or 24 inches in diameter.
Some brands use special optics to capture light. The tube terminates at the ceiling where a lens is installed. Some manufactures use a diffuser that more evenly distributes light.
Look for a one with an Energy Star rating. This way you can be assured that solar heat gain and heat transfer will be minimized.
Tubular skylights can be installed between existing roof rafters and ceiling joist thereby eliminating the need for framing alterations, which account for a major portion of the cost of a skylight installation.
Tubular skylights also eliminate the need to perform drywall work, insulation, roofing, flashing and painting. The dome comes with its own integral flashing system that is slipped into the existing roofing after a hole has been cut through the roofing material and sheathing.
Each manufacturer offers several flashing styles to correspond to various types of roofing material. Because of the ease of installation, the product can be installed, on average, in a few hours by a do-it-yourselfer.
Professional installation is also available for those who do not feel they can install it themselves. Consequently, the cost of the installed product is significantly less than that of a conventional skylight.
Tubular skylights are available at home centers and retail in the range of $270 to $450 depending on the size — double the cost for a professional installation. An optional light kit is also available with some brands allowing you to use your tubular skylight as a standard light fixture at night.
