Roof Eaves And Gables

In wood frame construction the primary structural members of a gabled roof frame are the ridge board and the rafters.

Roof eaves and gables.

An eave is defined as the edge of the roof that overhangs the face of a wall. Do not set it to match the main roof slope of the house. Remember the roof on the return is there just to shed a small amount of water. The underside of these and the faciaboard is the soffit.

Refer to my architectural roof types blog. The three primary variables to consider when designing the eaves for a gable roof are the width of the gable trim the projection of the eaves and the details at the corner of the gable ends. Gables gables typically provided an 8 200 mm overhang and were lined to the underside but there were wide variations in how the top or apex of the gable was treated figures 2 7. Gable or rake trim is attached to the sloping edges of roof gables to prevent wind driven rain from penetrating the exposed undersides of the roof panels that connect the ridge and the eave of your home.

The purpose of your home s roof is to protect the entire structure and you from weather. A gable roof consists of two sloped planes that meet at the ridge or peak and rest on the top plates of 2 parallel exterior walls. It is designed for maximum effectiveness and aesthetics. This is the portion of the roof that protrudes beyond the side of a house or building.

The final step is putting the roof on the eave and addressing what happens in the gable itself. Like rain snow sleet wind and hail. Then there is the verge which is the overhang that goes up the gables. The eaves are the sections that overhang the walls.

This first installment of a two part series focuses on eaves that do not return onto the gable. If the lower section of the roof rafters or rafter tail extends beyond the exterior wall the projection forms an overhang or eave. They were typically used above the bay windows but a small number of hipped roofs over bay windows were also built. A gable roofis a type of roof design wheretwo sides slope downwardtoward the walls and the other two sides include walls that extend from the bottom of the eaves to the peak of the ridge.

A slight return just enough to keep water from pooling is all you need.
