The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems.

According to the Oxford English Dictionary, eaves is derived from the Old English efes (singular), meaning "edge", and consequently forms both the singular and plural of the word.[1][2] This Old English word is itself of Germanic origin, related to the German dialect Obsen, and also probably to over.[3]

The primary function of the eaves is to keep rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. The eaves may also protect a pathway around the building from the rain, prevent erosion of the footings, and reduce splatter on the wall from rain as it hits the ground.

The secondary function is to control solar penetration as a form of passive solar building design; the eaves overhang can be designed to adjust the building's solar gain to suit the local climate, the latitude, and orientation of the building.[5]

Aesthetic, traditional, or purely decorative considerations may prevail over the strictly functional requirements of the eaves. The Arts and Crafts Movement influenced the American Craftsman tradition, which has very wide eaves with decorative brackets technically called modillons, for which there is not necessarily a real functional need; likewise the Italian-style eaves.

The eaves may terminate in a fascia, a board running the length of the eaves under the tiles or roof sheets to cap off and protect the exposed rafter ends and to provide grounds on which to fix gutters. At the gables the eaves may extend beyond the gable end wall by projecting the purlins and are usually capped off by bargeboards to protect the wall and the purlin ends. The overhang at the gable is referred to as a gable overhang, as opposed to eave overhang, or they both may be referred to as overhang.

The underside of the eaves may be filled with a horizontal soffit fixed at right angles to the wall, the soffit may be decorative but it also has the function of sealing the gap between the rafters from vermin and weather.

The line on the ground under the outer edge of the eaves is the eavesdrip, or dripline, and in typical building planning regulations defines the extent of the building and cannot oversail the property boundary.

Charles Edward Eaves was born to Floyd and Mariah Eaves on July 17th, 1941. He was the 4th of 7 children born to this union. He left this earth to go to his heavenly home on February25, 2024 at the age of 82.

Charles leaves behind a legacy of family and community service. He enjoyed spending time with family and friends. Especially if they shared his love for travel, fishing, and photography. In 1971 in the effort to bring together two things that he loved, his son and photography he created C&V Studios. His studio prospered through hard work and perseverance, and it sustained his family until he retired.

I have my PanV3 cams mounted under my eaves attached directly to the soffit. I had to fabricate a mounting base (PVC Board), drill a hole for the binding screw, and use a Forstner bit to recess the binding screw hole to the proper depth for the screw to reach the cam and tighten. Then I attached the mounting base to the soffit.

Our project has wrap over timber cladding and therefore no overhang on the eaves. Externally it all looks fine, but in section I can't get it to look even close to acceptable graphically, I'm sure there must be a solution. Image attached along with the same bay drawn in Vectorworks for how it should be drawn (ignore the gutter detail).

I hadn't realised the 'fascia depth' was needed to get the two cut function to work, which is vastly improving the look. I'm going to play with the fascias to se if I can get it looking nice in elevation as well.

I don't know what you mean when say LT can't "manipulate individual layers of the build-up", but I would model the buildup by sandwiching several Roof Types together. Pretty much the way it will be done in the field. FWIW.
