4×12 Gable Roof Plans

This step by step diy project is about 4×12 gable shed roof plans. This is PART 2 of the gable shed project, where I show you how to build the gable roof for this shed. In addition, you need to build and install the door to the shed. Make sure you read the local codes so you can comply with the legal requirements. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

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.

How to build a gable roof for a 4×12 shed

Building-the-gable-rafters

The first step of the project is to build the rafters for the top of the shed. Make cuts to the 2×4 beams and smooth the edges with sandpaper.

Fitting the top ridge

Continue the project by fitting the top ridge to the top of the shed. Use 2×6 lumber for the top ridge and 2×4 lumber for the supports. Drill pocket holes at both ends of the supports and then insert 2 1/2″ screws into the top ridge and into the plates. Center the supports to the top plates and make sure the corners are square.

Fitting the rafters

Fit the rafters to the top of the shed, every 24″ on center. Align the edges with attention and then lock the rafters into place with rafter ties.

Gable roof end panels

Fit T1-11 siding panels to the front and to the back of the shed. Align the edges flush and insert 6-8d nails to lock the panels into place tightly.

Building the overhangs

Assemble the overhangs from 2×4 lumber. You can adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings.

Fitting the overhangs

Fit the overhnags to the front and to the back of the shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them tightly into place.

Fitting the roof sheets

Fit 3/4″ plywood panels to the top of the shed. Align the edges with attention and leave no gaps between the panels. Use 1 5/8″ screws to secure the panels into place, every 8″ along the framing.

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.

Fitting the side roof trims

Fit the 1×4 trims to the sides of the shed. Use 2″ brad nails to secure the trims into place tightly. Make sure you install dripping edges, under the roof and over the trims.

Building-the-shed-door

Build the door panel from the T1-11 siding that you have cut out in the previous steps, when attaching the sheet to the front of the shed. Align the edges with attention and then secure the panel to the 2×4 trims with 2″ brad nails.

Fitting the jambs

Fit the 2×4 trims around the door opening. Cut the trims at the right dimensions and then secure them into place with 2 1/2″ screws. Insert the screws every 8″.

Fitting the front door

Fit the door to the opening and align the edges flush. Fit hinges and a latch so you can lock the door into place tightly. Moreover, install handles so you can open and close the door properly.

Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain over the components, so you can enhance the look of the shed. Moreover, the paint will protect the components from decay.
