Pitched roof eaves details.

The eaves detail shows where the roof members and coverings meet the wall of the dwelling. Eaves courses of tiles should be at same pitch as general tiling. To 18 in depending on the style of the building. The cavity is closed with a proprietary cavity closer.

If a sprocketted or bell cast detail is used then eaves courses should be no lower than the minimum recommended roof pitch. The main component of any eaves detail is the rafter tail the part of the rafter that extends beyond the exterior wall. To determine exactly what the rafter tail will look like i always make a full size drawing on a scrap of plywood of all the eaves elements including framing and finish materials see illustration above. The eaves of a pitched roof tend to extend around 150 300mm beyond the external face of the wall to provide protection from rain.

This video is about drawing a pitched roof eaves detail showing how the truss connects to the top of the wall. Some roofs have some of these aspects while other roofs may have all of these features. Avoid gable ends that are over 8 in. First of all there are many details to pitched roof types that can make construction more complex.

In some cases a closed or flush eaves can be designed which stops the rafters and ceiling joists at the face of the external wall where a fascia board is then fixed to the ends of the joists and the rafters. An eave is the portion of the roof that overhangs the outside walls of a house. The soffit is the underside of the eave and by measuring its width you can tell how much of an overhang you have. Fix a plywood board or proprietary tray to provide continuous support to underlay to prevent water retaining troughs.

When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in. Wide especially when the eave overhang is less than 12 in. The lack of eaves and a shallow not steep roof pitch are often design features that distinguish a manufactured home from a conventional home. There are ridges eaves hips abutments and the centerline of the ridge.
