According to Consumer Affairs, installing a skylight(s) in your home increases its resale value. But whether or not you are looking to sell in the near future, skylights are a great option for many homes.

Skylights can improve the look and feel of dark spaces, make rooms look larger, provide natural ventilation, provide natural light, and afford you views of the night sky.

So, what do you need to know about skylights?

  1. They are not one size fits all.
    • Skylights come in a variety of different shapes and sizes. Typical skylights range in size from 14”-72” and can be square, rectangular, circular, etc.
  2. They let in up to 30% more light than standard windows.
    • They are also UV rated. When looking at skylights be sure to check the UV rating—the higher the number, the fewer UV rays entering your home.
  3. There are two types of “glazing” to choose from (the material inside of your window frame–essentially the part that you look out of).
    • Plastic: typically shatter-proof, but can discolor and become brittle.
    • Glass: more durable, lasts longer, and can reduce exterior noise. These are typically the windows that we recommend and install.
      • There are a variety of options when it comes to glass, including tempered, laminated, impact, snow load, etc. Your window professional would discuss these options with you, and pick the glaze that is right for your specific home.
      • Many have more than one glass pane, and often have inert gas between the layers for efficiency.
  4. The most common skylights to choose from are fixed or vented.
    • Fixed skylights can’t open. They provide light, but no ventilation. They are often the least expensive option.
    • Vented skylights open, allowing for light and ventilation. There are several types of vented skylights:
      • Manual: these require someone to open them physically. Often, they can be opened with a control rod or turning/crank handle.
      • Electric: these require a power source, but are controlled with a button or remote. They often also include a rain sensor, which will automatically close the window if it is hit by rain.
      • Solar: similar to electric, but using solar panels to recharge a battery as opposed to a more traditional power source.
      • Many skylights can be programmed, and some can even be controlled remotely using a smartphone.
  5. Your skylight can be curb mounted or deck mounted. Much of this depends on the type of roof, and the angle of the window.
    • Curb mounted: installed in a raised platform or frame (typically made of wood) that the window rests on. This is typically used for flat roofs, or roofs made of certain materials.
    • Deck mounted: the window attaches directly to your roof deck.
  6. Many skylights are energy efficient.
    • We sell Energy Star rated windows, which are 10-25% more energy efficient than non- rated windows.
    • Many come with installed blinds which can help with, among other things, temperature control during extreme weather.
  7. Skylights should be installed with a new roof/roof facet.
    • You should not install a skylight on an existing roof. This will void any warranty, and makes your roof vulnerable to leaks and damage.
    • Skylights should be installed while installing a new roof or facet (section of roof). This will ensure that the skylight can be seamlessly incorporated into the design, and sealed appropriately.
