Measure the length of roof where you are planning to place cupola.
If you are planning to mount the cupola in the center of the roof of house, then, measure the entire unbroken roofline. Otherwise, measure the unbroken portion where you are planning to mount the cupola. Look at the unbroken roofline given in the diagram given below:
Centered cupola on the Entire Roofline
What is Unbroken roof line
Measure your roofline in feet. Cupola size should be 1-1.25 inch per feet of roofline. Measure the unbroken roofline and multiply lookby 1-1.25”. You will get the right size of cupola. For example, 24 feet unbroken roofline will have 36 inch size cupola.
For large size, building you should hire a professional architect or structural engineer so that they could suggest you the size according to the building.
Irrespective of the size of buildings, cupola can be a focal point. However, for larger buildings, barns, the size of roof should have more than cupola. It will really make your building exterior awesome. For example, 60 feet roofline can have three cupolas. Therefore, you can place one larger cupola at the center and other two small size cupolas on the sides.
Look at the diagram given below:
The gap between two cupolas should be even and size should be equal.
Important things while deciding the size of cupola:
- Correct roof dimensions: Because it will not be possible to modify after installation so, it is better to have accurate measurement.
- Correct Proportion: Cupola size and roof structure should align properly, so it is important to calculate the correct proportion. See Cupola Proportion
