Skylights can be flat or domed, fixed or vented. Some vented skylights even operate by an electric motor, while others open and close manually. Skylights get much more sunlight than regular windows so they normally are more tinted and equipped with Low-E coating. Because roofs have things fall on them, skylights are made to withstand impact.
- Fixed Skylights: Fixed in place and does not open or close.
- Manual Venting Skylights: Glass raises and lowers by a crank or by pushing upward.
- Electric Venting Skylights: Glass raises and lowers by an electric motor.
- Tube Skylights: Flexible tube runs between ceiling and roof and does not raise or lower.
Historically skylights have received poor reviews due to leakage. There are a variety of reasons skylights can leak but it all really comes down to poor quality skylights and installation. Typically, a skylight can last between 8-15 years, depending on how well it was installed and the quality of the skylight’s manufacturing.
