Give four functions of roofs?

1. Protection: Roofs provide protection from the elements, such as rain, snow, wind, and sunlight. They help to keep the interior of a building dry and safe from damage.

2. Insulation: Roofs help to regulate the temperature inside a building by providing insulation. This can help to reduce energy costs by keeping the building cooler in the summer and warmer in the winter.

3. Structural support: Roofs provide structural support for a building, helping to distribute the weight of the roof and any additional loads, such as snow or equipment, evenly across the building's walls and foundation.

4. Aesthetic appeal: Roofs can enhance the overall appearance of a building and contribute to its architectural style. Different types of roofs, such as gable, hip, or flat roofs, can add character and visual interest to a structure.
