Roof Length Eave Side

Some ridge vents have a baffled ridge.

Roof length eave side.

An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. Refer to my architectural roof types blog. As shown in the illustration the soffits are 100 perforated along the longer side and 50 perforated along the shorter side. Then multiply the length of the longest side by the length of this central line.

Begin by measuring from your extended fascia to the peak of the shed. An eave is defined as the edge of the roof that overhangs the face of a wall. On a home s exterior eaves can project stick out beyond the side of the building serving both decorative and practical functions. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.

If you have a roof section that s 30 feet 9 1 m long and 12 feet 3 7 m high multiplying those dimensions would give you an area of 180 square feet 17 m 2. The eaves are the edges of the roof which overhang the face of a wall and normally project beyond the side of a building. They also help to frame windows on upper stories. Eaves form the overhang to distribute water clear of the walls.

8 inches and you have an 8 in 12 pitch. The basic formula for finding the area of a triangle is the base times the height in this case the distance between the base and the peak. Pitch measurement method 1. 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.

That is their functional purpose. If this distance measures 4 inches you have a 4 in 12 pitch. In contrast a gable or rake is the overhang of a building that occurs on the side that is topped by a gable roof. The eave of a house has come to mean the underneath area of the roof that projects from the exterior siding as opposed to a cornice which is part of the entablature in classical architecture.

Use this measurement to cut a length of 2 4 making sure that one side of the board is miter cut to match the peak of the roof. Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. Wind blows over the ridge and pulls heated air and moisture from the attic creating a uniform air movement that eliminates hot spots. However there is also an architectural purpose to them.

This is the portion of the roof that protrudes beyond the side of a house or building. Ridge vents run along the top length of the roof. To balance the air intake at the top of a roof with asymmetrical slopes the percentage of ventilation openings along the base of the longer side should be increased and those along the base of the shorter side decreased.
