Skylight / July 10, 2018 / Faye Savoie
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.
Since most skylights are meant to be installed on a roof with asphalt shingles you may need to pay extra for flashing if you have tile or metal roofing. When you think of skylight design you may think that only refers to the visible shape of the panel chosen; in fact there are many aspects to skylights that relate to the design and affect the usefulness of the skylight. Some skylights need to provide light for a large area while others have a different purpose. Learn all you can about skylights and skylight design as a consumer before you consult a professional. This will help you to understand better the decisions you will have to make. Skylights are beneficial to have in your home for many reasons.
Glass and acrylic or plastic skylights are available. Tubular skylights are relatively new on the scene. The small size allows them it to be used in spaces where full-sized skylights cannot. Hallways bathrooms even closets can accommodate a tubular skylight. They provide a lot of light in spite of their small size. The concept and installation process are basically the same as for a regular skylight except they have an enclosed tunnel of reflective material to reflect the light. They are available in many sizes. The small ones are 10 to 12 inch diameter and the large ones are 24 inches. Flat glass skylights come mounted in a wood or integrated rubber and metal framework and require no additional curb construction.
