Skylight / July 11, 2018 / Nicolas Charlebois
When these are pulled away and removed the drenched and water damaged roof beams come into view. Moisture comes from both inside and outside. Weather isnt the only thing that causes skylights to leak. Warm air from inside the house can catch in the skylight as it rises on warm air and then drips down onto furniture and valuables below. Modern skylight replacements can come with what is called low-e glass. This low emissivity glass keeps energy meant to heat or cool a room in and helps to reflect heat and cold out and away from the light itself. This is usually done through a special film that the glass is coated with. This film can block out UV rays and comes in many different filtering shades.
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.
