In most buildings, you will see these triangular provisions at the top of the roof.

It is called Roof lantern, Roof skylight, Roof fan light, etc.

 I know you don't know the purpose of its provision. Let me tell you.
It is there for two basic reasons.

One is that it serves as exhaust to let out excess heat and let fresh air into the roof.

The other reason is that it serves as an additional aesthetic to the roof design.

Another day, it serves as a provision to let sunlight within the roof area.

When adopting it into your roof, avoid using the same type of roof material used in your roofing sheet to do it because if you do it will nolonger serve the purpose of letting in light. It is done using a transparent material that allows light to penetrate.

Now I understand this thank you for sharing.
