Skylight / July 11, 2018 / Nicolas Charlebois
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.
Roof skylights bring in natural sunlight into your house and add to the style of your house. But those who install it are always worried about one problem and that is a leaking roof skylight. It cant be denied that there is increased risk of a leak but if you install and seal your skylight properly you can make your skylight absolutely leak proof and secure. Skylights have a reputation that they always leak. But it is not so. You must not let this rumor stop you from installing a roof skylight that you have always wanted. There has been great progress in technology and techniques used in installing a roof skylight and if the skylight is installed properly there is hardly any chance of it developing a leak.
It will also make all the difference for a skylight that doesnt have newer methods for moving condensation away from the window. It is possible that some skylights are suffering manufacturer related defects. Most worthy manufacturers of skylights or replacements will guarantee their product. A new and complete skylight will be sent and installed hopefully at no cost. It will require the same installation techniques as applied with the first but will obviously be better all around. It is often only when installing a replacement skylight that the damage caused by the original is noticed. The moisture damage caused to a roof is often hidden by the shingles and failed flashing around a skylight.
