8×12 Shed Roof Plans

This step by step diy project is about 8×12 gable shed plans. This is PART 2 of the storage shed project, where I show you everything you want to know about framing the gable roof. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a 8×12 shed roof

Building-the-rafters

The first step of the woodworking project is to build the rafters for the shed. As you can easily notice in the diagram, you need to make 25 degree cuts to both ends of the slats and then cut the birdsmouth. Smooth the edges with sandpaper for a neat result.

Bottom rafter

Build the bottom rafters from 2×4 lumber, as well. Make 65 degree cuts to both ends of the beams. Smooth the edges with sandpaper for a professional result. Lay all the rafters on a level surface and then leave no gaps between the components.

Fitting the gussets

Use 1/2″ plywood for the gussets and then lay them over the joints. Align the edges with attention, drill pilot holes through the gussets and insert 1 5/8″ screws into the rafters.

Fitting-the-trusses

Fit the trusses to the top of the shed, making sure you place them every 24″ on center. Use a spirit level to plumb the trusses and then lock them to the top plates with rafter ties.

Gable end supports

Fit a 2×4 support to the front and back gable ends of the shed. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ screws.

Assembling the overhangs

Assembling the overhangs for the shed is a straight forward project, as you need just 2×4 lumber. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings. Place the blockings evenly spaced.

Fitting the overhangs

Fit the overhnags to the front and to the back of the shed. Align the edges with attention and drill pilot holes. Insert 3 1/2″ screws so you can secure the overhangs into place tightly.

Fitting the roof sheets

Cut the 3/4″ plywood sheets for the roof of the 8×12 shed. Align the edges with attention, drill pilot holes and insert 1 5/8″ screws, so you can lock them into place tightly. Insert the screws, every 8″ along the rafters for a professional result. Leave no gaps between the sheets for a neat result.

Side roof trims

Fit the 1×6 trims to the sides of the shed. Align the edges with attention and then lock them into place with 2″ brad nails.

Fitting the roofing

Cover the roof of the shed with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a large piece for the top ridge.

Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Read the instructions labeled on the asphalt shingle packs before installing them into place tightly. Start with the bottom left side of the roof and install them all the way to the top.

You need to check out PART 3 of the shed, so you learn how to build the double doors and how to fit the rest of the trims. If you have’t looked over PART 1 yet, I recommend you to do it, as it will show everything you want to know about building the frame of the shed.
