12×20 Field Shed Roof Plans

This step by step diy woodworking project is about a 12×20 field shed roof plans. This is PART 2 of the shed project, where I show you how to build the gable roof. This roof has a 2:1 pitch, but you can adjust it super easily. 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 12×20 field shed roof

Rafters-for-shed

Use 2×6 lumber for the rafters. Make 23.8 degree cuts to both ends of the 2×6 rafters. Mark the cut lines to the rafters and then get the job done with a circular saw. Smooth the edges with sandpaper.

Bottom-chords—12-ft-truss-field-shed

Use 2×6 lumber for the bottom rafters, as well. Use a circular saw to make the angle cuts at both ends.

Truss supports

Use 2×4 lumber for the vertical supports. Use a saw to make the angle cuts at the top of the supports and then fit them into place. Align the edges with attention.

Fitting the gussets

Use 1/2″ plywood for the gussets. Lay the gussets over the joints and align the edges with attention. Use 1 5/8″ screws to lock the gussets into place.

Fitting-the-trusses—12×20-field-shed

Fit the trusses to the top of the shed frame. Place the trusses every 24″ on center and plumb them with a spirit level. Use rafter ties to lock the trusses into place tightly.

Gable ends

Use T1-11 siding sheets to the side gable end panels. Align the edges with attention and leave no gaps between the panels. Insert 6d nails, every 8″ along the framing.

Roof sheets 1

Use 3/4″ plywood for the roof sheets. Cut the sheets at the right dimensions and then secure them into place with 1 5/8″ screws, every 8″ along the framing.

Roof sheets 2

Fit the roof sheets to the other side of the shed. Use the same techniques described above to secure the sheets into place tightly.

Ceiling sheets

You can attach 1/2″ plywood sheets to the front overhang. Cut the sheets at the right dimensions and then fit them into place. Align the edges with attention and leave no gaps between the sheets. Insert 6d nails to secure the sheets into place tightly.

Side roof trims

Fit the 1×8 boards to the sides of the shed. Align the edges with attention and insert 3 1/2″ screws to lock them into place tightly.

Front and back Roof trims

Fit the 1×8 trims to the front and back of the shed, as well. Fit the 1×8 trims to the back of the shed roof, as well. Align the edges with attention and insert 2 1/2″ screws to lock them into place tightly.

Fitting the roofing

Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit. Alternatively, you could also install metal sheets.
