What is an eave on a roof?

An eave is the lower edge of a roof that overhangs the walls of a building. It serves several purposes, including protecting the walls from rainwater runoff, preventing water damage to the foundation, and providing shade for the windows and walls. Eaves can also help regulate temperature by providing insulation and ventilation to the building.

Eaves are typically constructed by extending the rafters of the roof beyond the outer walls of the building. They can be designed in various styles, such as boxed, open, or enclosed eaves. The size of the eave overhang can vary depending on the architectural style of the building and the local climate.

In addition to their functional benefits, eaves can also add visual interest and architectural detail to a building. They can be decorated with trim, brackets, or other design elements to enhance the overall aesthetic of the structure. Eaves are an important component of a well-designed roof and play a key role in protecting the building from environmental elements.
