Skylight Window Replacement

A skylight window replacement is a good choice for homeowners looking to bring more light into their bedroom, living room area, or bathroom. These windows bring sunlight in through the roof of the home and often offer useful ventilation to let heat out during the warmer months of the year. Some skylight windows even serve as emergency exits in attics or low ceiling rooms.

Types of Skylight Windows

You have several choices when it comes to skylight windows. Skylight windows vary in terms of functionality, material, and shape. Shapes include pyramid, pitched, and sloped skylights. There are also choices when it comes to window glasses and glazing. Below we will cover the different types of skylights in terms of how they function.

Fixed Skylight Windows 

Fixed skylights are non-moving. These roof-mounted windows do not open in any way and can not be used for ventilation purposes. They tend to last the longest and require the least amount of maintenance compared to other types of skylight windows.

Manual Ventilated Skylight Windows

Manual ventilating skylights typically crank up and out to provide ventilation. They are simple to operate and work similarly to an awning window. You crank the handle in one direction to open the skylight and crank it the other way to close it once again.

Electric Ventilated Skylight Windows

An electric venting skylight works much the same as a manual, but it is electrically powered. This is handy for skylights positioned in hard-to-reach areas. You press a button and the skylight opens, you push another button and it closes. Some even run off solar power and have rain sensors to open and shut the windows automatically depending on the weather conditions.

Roof Skylight Windows

Roof skylight windows are the option you will want to choose for attic rooms with no flat walls. These windows open up and out all the way, offering the occupants a way out of the room in the event of a fire. They are often required by code and they make an easier option than adding a dormer with a standard window.

Pros of Skylight Windows

  • Improved Attic Ventilation
    Skylight windows are one of the best options for ventilation and safety in an attic room with slanted ceilings. That’s because you can’t fit most standard windows in that angled setup without them leaking. Skylight windows are designed to keep the water out, but they will also help allow air into your home or even allow escaping during a fire if that’s a concern.
  • Increased Natural Light
    Although skylights are one of the least common windows used in homes today, they are still a great option for bringing sunlight in through the roof of the home.

Cons of Skylight Windows

  • Extra Maintenance
    Unlike most windows installed on a home, maintenance is vitally important for skylight windows. If they aren’t maintained properly they will eventually start leaking and cause issues in your home. Annually inspect your skylights from the roof while paying particular attention to the flashing surrounding the skylight.
  • Potentially Damaging UV Rays
    If you’re going to install a skylight window over top of furniture, carpeting or other items in your home that can be damaged by UV light you should consider a Low-E treatment to help keep out the more damaging rays. It will keep UV rays from making it into your home and help keep everything in better shape overall.

Replacement skylight windows are a nice option for accenting your home and bringing in more light. They can also ventilate a room or even provide an escape route. They often pair well with other popular window types. If you do decide to have a skylight window added to your home make sure that it is sealed with flashing properly and consider adding in things like insulated glass and low-e treatments to help protect your home and keep it insulated.
