Open eaves roof.
Open eaves provide access for the effects of weather.
Types of eaves.
In an open eave design the roof rafters or joists and roof sheathing are visible.
The overhang keeps any rainfall away from the walls whilst the junction where the roof meets the wall is also protected from water ingress.
Over time exposure to the elements and damage created by nesting animals can rob your home s eaves the overhanging edges of the roof of their attractive appearance and structural strength.
Doing so raises the eave which prevents it from conflicting with the window head height.
A box eave is enclosed with a soffit.
A roof can come to an end in basically three ways.
The eaves are the edges of the roof which overhang the face of a wall and normally project beyond the side of a building.

In the modified houses major structural problems such as leaking roofs were repaired windows were screened open eaves were blocked with bricks and mortar cement floors were repaired or constructed and rain gutters and a rain water storage tank were added.
Start with the rafter tails the main component of any eaves detail is the rafter tail the part of the rafter that extends beyond the exterior wall.
