A hip roof add a certain beauty to a backyard shed. A hip roof is defined as a roof that has all the sides sloping down to the walls.So the ends of the shed roof look like the sides. Without the gable ends protruding up it gives the roof a softer feel.
A hip roof on a shed must be "stick framed", meaning each rafter on the hips must be installed individually. Regular gable roofs can have the rafters or trusses assembled on the ground and then lifted into place. This make the hip roof a bit harder to build than the gable roof. But the hip roof has been built for hundreds of years and is a very solid roof.
The roof slope for most of our sheds is a 6 in 12 pitch. We use 2x6 boards so that the rafter tails have plenty of wood after the seat and birdsmouth cuts are made.
You will see on the plans that the actual hip rafters have a lower slope than the jack rafters and common rafters on the plans.
The roof on the hip roof shed designs is a bit tougher to build than our other shed roofs but if you are looking for a challenge and want to have the beauty of this roof style then this is a great shed building project that will provide a lot of satisfaction when you look at it an think "I built that".
Build the Shed up to the top wall plates. After installing the wall plates on the shed walls you will build the shed roof by completing the following steps:
Our shed plans utilize a Terminal Hip Roof Framing Design. This type of roof framing means that the hip rafters rest on the first regular truss.
This drawing shows the different types of raftes used to frame a hip roof.
Measure half the width of the shed back from the end of the shed and mark the top plate. This is the center line of the Terminal Rafter. Set the Terminal rafter on the top plates and attach it to the plates.
Measure from this point 24" on center along the wall top plates and mark the center lines of the rest of the rafters. You can move the marks over 3/4" to make them easier to see once you set the rafters on.
The common rafter taht goes between the two hips is the same as the other common hips. It is installed to help hold up the Terminal rafter and make it easier to install the hip rafters.
The two hip rafters are now installed. Check the top edge of the hip rafters to make sure that they are the same height as the common rafter that was installed.
You can do this by using a straight board laid from hip rafter to hip rafter and verifying that the common rafter is not too high or too low. It should be 1/4" or less.
Now cut out the Jack Rafters and install them between the hip rafters and the top plate. You will need to measure perpendicular to the Center Common Rafter over 24" and put a mark on the hip rafter to know where the center line of the top of the jack rafter will sit on the Hip rafter.
Use straight board laid perpendicular to rafters to check that top edge of rafters are flush with each other when installing each rafter to ensure that roof is flat.
Install the Terminal Rafter and Hip/Jack rafters on the opposite end ot the shed following the same process as you did with the first end of the shed.
Install the Common Trusses/Rafters between the two shed ends. Make sure that the layout is 2'-0" on center
Check that the ends of the rafers are close to the same length +- 1/4" and then install the fascia board.
