This step by step woodworking project is about building a roof for a 12×18 run in shed. After building the frame for this loafing shed, you need to frame the roof, so you can protect the items against bad weather. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. See my other DIY projects HERE.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

Building a run in shed roof
Use 2×6 lumber for the rafters. As you can easily notice in the diagram, you need to make birdsmouth cuts to the rafters. Mark the cut lines on the beams and then get the job done with a saw.
Fit the rafters to the top of the run in shed, every 24″ on center. Use rafter ties to lock the rafters to the top plates of the walls.
Use T1-11 siding for the sides of the shed. As you can easily notice in the diagram, you need to adjust the size and the shape of the sheets, so they fit into place properly. Use 2″ brad nails to secure the sheets to the frame of the shed. Leave no gaps between the sheets for a professional result.
Attach the T1-11 siding sheets to the back wall of the run in shed, as well. Align everything and secure the sheets to the wall frames durably.
Fit the 2×6 supports to the front wall of the shed. Drill pocket holes and lock the supports into place with 2 1/2″ screws.
Fit the 3/4″ plywood sheets to the top of the run in shed. Align the edges flush and then lock the sheets to the rafters, every 8″. Leave no gaps between the sheets and the drill pilot holes before inserting the 1 5/8″ screws, to prevent the wood from splitting.
Fit the 1×8 trims to the sides and to the front of the shed. Align the edges with great care and then use 2″ brad nails to lock them into place tightly.
You could fit asphalt shingles to protect the shed, as it is a straight forward solution. Therefore, install roofing felt over the roofing sheets, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Place a starting course at the bottom of the roof, before installing the asphalt shingles. Always read the manufacturing instructions before starting the installation, as there are several aspects that differ.
Smart Tip: The first course should star with a 3 tab shingle, the second course with a 2 1/2 tab , the third course with a 2 tab, the forth course with a 1 1/2 tab, the fifth course with a 1 tab, the sixth course with a 1/2 tab. Repeat the process from the beginning, starting with the seventh course. Don’t forget that the shingles should overhang from the drip edge about a 1/4″. In addition, secure the asphalt shingles to the roof decking with tacks.
If you want to build the frame for this run in shed, make sure you take a look over PART 1. I am sure this 12×18 run in shed will serve you well for many, many years in a row. This shelter is extremely versatile, as you can use it for many purposes. If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
