What is a Clerestory Roof?

A clerestory roof is a vertical wall with a row of windows above the roof line. These roofs feature two sloping sides – one under the row of windows and one on top.

The purpose of a clerestory roof is to maximize natural light and allow for ventilation. But, even though these roofs add to the looks and function of a home, they require a lot of maintenance.

Here’s what you should know before adding a clerestory roof to your home.

What is a Clerestory Roof Design?

A clerestory roof highlights a row of windows. Its design features a short vertical wall on top of a roof. The windows allow light to flood into a space while still providing privacy. And in some instances, clerestory roofs can increase the energy efficiency of homes.

You can customize a clerestory roof to fit any house, depending on the windows and roof style you choose.

The Pros and Cons of Clerestory Roofs

While clerestory roofs are a unique design feature, they also have practical advantages.

Pros:

  • Increased natural light while maintaining privacy – Since clerestory windows are on a roofline, they provide privacy while allowing natural light into the home.
  • Ventilation – Some building designs incorporate these roofs to increase ventilation.
  • Solar heat gains – If you live in a cold climate, clerestory roofs can help with solar heat gain when north-facing.
  • Aesthetics – Clerestory roofs have a unique look.

Cons:

  • Allow a place for heat to escape – Even though north-facing windows allow for solar gains, these windows also give heat a place to escape if the windows aren’t airtight.
  • Obstructive light – If you live in an area with many streetlights, the light can enter your home at night through the windows.
  • Hard-to-find window coverings – Finding window blinds or shades for clerestory windows can be challenging.
  • Upkeep – With a row of windows in a clerestory roof comes the maintenance of keeping the windows in good condition, checking for air leaks, and replacing them when needed.

What’s the Difference Between a Roof Monitor and Clerestory Roof?

A roof monitor is a raised structure built on a double-sloped roof. Roof monitors can be of various sizes and sometimes look like mini-buildings on top of a house. Clerestory roofs feature only one short vertical wall sitting between two slopes. Both designs are often filled with windows but look quite different.
