How high should kitchen chimney from ground?

The height of a kitchen chimney from the ground depends on various factors such as the local building codes, roof type, and the height of the surrounding structures. Here are some general guidelines:

1. Local Building Codes:

It's essential to check the local building codes and regulations for specific requirements related to the height of kitchen chimneys. Some areas may have specific guidelines regarding the minimum height of chimneys, measured from the ground or the roofline.

2. Roof Type:

If your kitchen chimney extends through a sloped roof, the chimney should be at least 3 feet above the highest point of the roof within 10 feet horizontally of the chimney. This is important to ensure proper ventilation and prevent backdrafting.

3. Surrounding Structures:

The height of your kitchen chimney should also consider the height of nearby buildings, trees, or other obstructions. The chimney should be high enough to prevent smoke or fumes from being trapped or redirected towards neighboring properties.

4. Chimney Cap and Flashing:

A proper chimney cap and flashing should be installed to prevent water infiltration and ensure adequate ventilation. The cap should be at least 1 foot higher than the top of the chimney to allow for proper airflow.

5. Height Recommendation:

In general, it's recommended to have the kitchen chimney extend at least 2 feet above the highest point of the roof. However, this recommendation can vary based on the factors mentioned above.

It's always best to consult with a qualified roofing or chimney professional to ensure that your kitchen chimney is installed according to safety standards and local regulations. They can assess your specific situation and provide guidance on the appropriate height for your chimney.
