What Is Clerestory Roof?
A roof is an important part of any residential building. It is the structure that makes up the upper portion of any building, covering the top. Roofs can be of various forms and designs. They can either be sloped or flat, protruding or aligned, etc. One of the forms of roofs is the Clerestory Roof.

The roof panels of Clerestory Roofs are designed to sit at heights that are marginally different. This difference gives way for a vertical wall to be built. The wall usually showcases windows, to allow sunlight and airflow to even the topmost interior of the building or house.
Installing a Clerestory Roof has to be planned beforehand, to accommodate the directions of sunlight, breeze, etc. This is done to obtain maximum benefits of the Clerestory Roofs. It is an easy-to-install feature that has practical uses for the interior as well as beautifies the exterior.

Why Install a Clerestory Roof?
Clerestory Roof is installed mainly for the fresh air and sunlight that they allow, without compromising the privacy of the individuals inside.
Clerestory Roof is also installed for its unique design properties. When designed and decorated, these walls between the roof can give the whole building or structure an elegant and different look.

Types of Clerestory Roof
Clerestory Roof come in various kinds, depending on the requirements of each project. There are mainly two types of Clerestory Roofs used in buildings or structures, Symmetrical Clerestory Roofs and Asymmetrical Clerestory Roofs.
1. Symmetrical Clerestory Roof
Symmetrical Clerestory Roof is where the roof is designed to have both roof halves of the building or structure to be slanting. These slanting roofs are built to an angle that resembles a triangle. One slanting roof lies above the other with a featured vertical wall between both slant roofs. The vertical wall typically has either a few windows or a long window showcasing its unique design.
2. Asymmetrical Clerestory Roof
Asymmetrical Clerestory Roof is where the roof is designed to have one half of the roof of the building or structure at a descending angle and the other as a flat roof. The slanting roof lies above the flat roof with a featured vertical wall between both the roofs. The vertical wall typically has either a few windows or a long window showcasing its unique design.
What Are the Considerations of Using a Clerestory Roof?
The weather and climate conditions of the place where Clerestory Roofs need to be installed in buildings or structures have to be taken into consideration before starting the project. Very hot climates can statistically decrease the function of these roofs and cause a negative impact on the appeal of residential buildings or structures.
Similarly, when planning to install Clerestory Roofs onto buildings and structures, serious consideration has to be given to the alignment and placement of the vertical wall as well as the windows. If these are not planned professionally, the direct heat or light may impact the residents negatively.
When deciding to install a Clerestory Roof in an already built structure or roof, the building cost and construction challenges have to be considered well in advance. It is possible to add a Clerestory Roof to a previously built roof with the right planning and the help of professional architect experts.
Another consideration to keep in mind when deciding to install Clerestory Roofs onto already built structures or buildings is the duration of the existence of the structure. If the existing structure is in a deteriorated condition, it is very risky to go ahead with the construction process. This can even lead to structural failures.
Installation of Clerestory Roofs is an expensive construction project and this needs to be carefully considered before going ahead with the construction process.
The time it takes to install a Clerestory Roof is comparatively longer than the time it takes to install standard roofs. This is why it is important to consider this factor before starting the construction process.
Clerestory Roofs are a unique design for roofing and so they also require unique designs of the foundation and structure for the fitting and installations. It has to be taken into consideration whether the type of roof that is designed for the specific building or structure will be compatible with the Clerestory Roof.
When Clerestory Roofs are installed in buildings or structures, one of the advantages is the pleasant view it allows. So, it has to be considered when planning to install Clerestory Roofs whether the outside environment and surroundings are worth the view.
Similarly, it has to be considered if the surrounding is free of any obstacles which could prevent proper daylight to enter through the windows. If not, the purpose and function of the Clerestory Roof will be diminished.
What Materials are Used in a Clerestory Roof?
