10x20 Gable Shed Roof Plans

This step by step diy project is about 10×20 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. The roof adds a character touch to the shed project, but it also drains the water properly. 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 10×20 shed roof

Building-the-shed-trusses

The first step of the project is to build the trusses for the 10×20 shed. Use 2×4 lumber for the rafters. Cut the top end of the regular rafters at 60 degrees and both ends of the bottom rafters at 30 degrees. Use a good miter saw to make the angle cuts. Lay the rafters on a level surface and then leave no gaps between the components.

Truss supports

Build the supports for the trusses from 2×4 lumber. Cut the top of the supports at 60 degrees, by using a miter saw. Align the edges with attention and make sure the corners are square.

Fitting the gussets

Use 1/2″ plywood for the gussets. Mark the cut lines on the plywood sheets and then get the job done with a circular saw. Fit the gussets over the joints and then lock them into place with 1 5/8″ screws.

Fitting-the-trusses

Fit the trusses to the top of the shed. Place the trusses 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 the 2×4 supports to the gable ends, so you can attach the gable end panels. Drill pocket holes at both ends of the supports and lock them into place with 2 1/2″ screws.

Gable end panels

Fit the T1-11 siding panels to the gable ends, after cutting them to size. Leave no gaps between the panels and lock them to the framing, every 8″, using 6-8d nails.

Building the overhangs

Assemble the overhangs from 2×4 rafters and blockings. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings. Place the blockings equally spaced for a professional result.

Fitting the overhangs

Fit the overhangs to the front and to the back of the 10×20 shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws into place.

Fitting the roof sheets

Use 3/4″ plywood for the roof sheets. Cut all the panels at the right size, as shown in the diagram and then lay them to the top of the roof. Align the edges with attention, drill pilot holes and insert 1 5/8″ screws to lock them into place, every 8″ along the rafters. Leave no gaps between the sheets for a professional result.

Side roof trims

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

Front and back roof trims

Build the trims for the front and for the back of the 10×20 gable shed. Align the edges and insert 2″ brad nails so you can set the trims into place.
