Skylight / July 12, 2018 / Odo Vaillancour
The acrylic dome is typically mounted in an aluminum frame which is in turn mounted on a box called a "curb." Once the hole is cut in the roof to the manufacturers specifications the curb is typically constructed on-site to raise the skylight above the level of the roof sheathing. Site-built or factory-supplied flashings are used to seal the roofing around the curb. Domed skylights are available in clear smoked bronze or other tints. Some domed plastic skylights are flush mounted which means that the lens piece and flashing piece are both made of plastic and then placed on the roof without a curb. The problem with this type is that they are loud and very susceptible to leakage.
There are shades screens and many other window treatments available for the skylights. Thus you may customize even the roof skylight to create a dream house you had always imagined. Jerry asks "I am thinking about installing a skylight. I have heard that there are different types of skylights. My in-laws have one that I think is plastic. It is very noisy when it rains and is extremely hot. Ive heard that there are glass ones. What are the different types? Is there a glass one that doesnt make all the noise in the rain and filters some of the heat? Yes there are different types. Lets discuss them. The term skylight or roof window is often used to describe several styles.
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.
