Skylight / November 16, 2018 / Nicolas Charlebois.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
The structure of the house is another deciding factor. If there are beams pillars or pipes in the way the skylight on the roof may not get the right amount of visibility. Making structural changes is not an affordable option in most cases. So it is better to evaluate the room before you place skylights on the roof. In most cases skylights should be built into the house at the time of drawing the design of the house. In case skylights are introduced at a later point of time care must be taken to ensure that they are placed correctly and installed properly. Skylights are overhead windows often in a roof that allow sunlight to filter inside any enclosed area; they are a great natural light option to artificial lighting solutions during the daytime.
You will need to position and mark the opening on the ceiling after the skylight is installed. Take into consideration the size of the room and the amount of light you wish to bring in and select the size and position of the hole accordingly. Once the skylight is installed and the ceiling hole is cut its then a matter of connecting the two with the shaft which is typically constructed from 2x4 or 2x6 lumber. The angles involved typically require some tricky framing and is probably best left to an experienced carpenter. After the framing is completed the inside of the shaft is covered with wood or drywall and the attic side is insulated to minimize heat loss.
Skylights may seem inexpensive at first glance since a quality 2x4 foot skylight along with a flashing kit costs anywhere from $100 to $400. However you need to consider adding another $3000 for installation costs. That being said you first need to carefully evaluate if installing a skylight is the right thing for your home. Till recently having a roof slope determined if you could install a skylight. Flat roofs or those which were too steep required special tools and techniques. However many of the skylight kits available today include a comprehensive installation kit and procedures which permits it to be installed on all types of roofs.
