Flat Roof Overhanging Eaves

Too little can allow water to seep into rake or fascia boards.

Flat roof overhanging eaves. An overhang protects the upper portion of the wall that it is attached to from rainfall and it also shades the windows under it from the sun. Mark where the drip edge begins to overhang and one inch further out from that overhang. Eaves form the overhang to distribute water clear of the walls. With a flat shed roof the roof simply extends past the wall plate to provide an overhang.

While flat soffits work well in some situations in most they result in pork chop eave returns. Start with the rafter tails. The eaves are the edges of the roof which overhang the face of a wall and normally project beyond the side of a building. Cut the entire drip edge by your second mark so that it only hangs past the edge by.

The edge of the shingles should hang over a roof between an inch and an inch and a half or between a half inch and three quarters of an inch if drip edge flashing is installed. 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. Too much overhang and the shingles could blow off in high winds. The length of the overhang depends primarily on the climate.

Closed eaves with flat soffit and no raised heel the default in eave design is a flat soffit. I recently built a small outbuilding with a 6 in 12 pitch roof that offers a perfect example for showing the process i use to build eaves and rakes. Overhangs are extensions of the roof beyond the exterior wall i e the joists rafters or trusses and the decking they support cantilever past the wall. Overhangs are common in most house designs providing protection against both wind and rain.

Proceed with extreme caution when using a flat soffit. For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves. My system is straightforward and provides strong positive attachment of the overhanging elements to the building as well as solid nailing for the finish materials. Do the same for flashing where it overlaps the edges of the overhang.

Unscrew the gutters at the brackets then pull out the nails holding them in place and lower them down safely. Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. Remove the gutters and roof flashing if needed. They also help to frame windows on upper stories.

That is their functional purpose. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. In order to give yourself clear access to the eaves you may first need to detach the drainage structures covering them. Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage.
