Modern roof overhang detail.

A closed eave has very little or no overhang extension beyond the siding. Notice how the eave and rake overhangs of traditional gable roofs is eliminated for a clean edge profile where the wall siding butts right up to the roof flashing. The most primitive buildings are nothing but a roof. Doing so keeps basements and crawlspaces dry and it also helps to.

Martin and jon are right that a roof overhang is the best way to protect the siding. There is also no gutter in the detail so you will be effectively routing rain down your wall. With that in mind we kept a roof overhang at the eaves as it provides a nice shadow line and protects the second floor windows from a bit of the summer sun. An open eave has a pronounced overhang often revealing projecting roof beams or brackets.

Most modern cabin architecture out there seems to be eaveless meaning that there is no or very minimal roof overhang eaves that go beyond the building structure. It feels that there is a common opinion among architects that this minimal look is the thing. But in a traditional modern hybrid like this. I can understand not wanting one with a flat roof but the sloped roof without overhang i never understood.

Christopher alexander writes in the pattern language no. But are they really necessary. A box eave is enclosed with a soffit. The roof plays a primal role in our lives.

The roof is what really gives a house it s personality. If the roof is hidden if its presence cannot be felt around the building or if it cannot. In the czech republic a1architects built a lakeside charred timber teahouse with a substantial roof overhang to ensure that the outbuilding would be a modern micro space beautiful and cozy and comfortable to stay in for hours. The gable roof design in the example below is simple clean and modern.

There is no good way to make that last. Powered by an electric motor the retractable roof slides back and disappears. They are essential for framing and shading windows reducing splashback and getting rain to fall far enough away from the foundation. Photograph courtesy of rever drage.

Roof overhangs might look relatively routine but there is a lot of design thinking that goes into creating the optimal dimensions for each one.
