14×20 Gable Shed Roof Plans

This step by step diy project is about 14×20 shed roof plans. This is PART 2 of the large storage shed project, where I show you how to build the gable roof for the project. 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.

How to build a 14×20 gable shed roof

rafters

The first step of the project is to build the rafters for the gable roof of the 14×20 shed. Use a miter saw to make angle cuts to both ends of the rafters. Mark the cut lines on the rafters and then get the job done with a circular saw. Smooth the edges with attention.

Bottom rafter

Build the bottom rafters and then lay them on a level surface. Align the edges flush and leave no gaps between the components.

Assembling the trusses

Build the supports for the trusses. Make sure the corners are square.

Fitting the gussets

Build gussets for the joints from 1/2″ plywood. After cutting the gussets you need to lay them over the joints. Insert 1 1/4″ screws to lock the gussets into place tightly.

Fitting-the-trusses

Fit the trusses to the top of the shed. Plumb the trusses and then place them every 16″ on center. Use rafter ties to lock the trusses to the frame of the shed.

Gable end panels

Fit T1-11 siding sheets to the gable ends of the shed. Mark the cut lines on the sheets and then get the job done with a circular saw. Leave no gaps between the sheets for a professional result. Align the edges with attention and insert 6d nails to lock the sheets into place tightly.

Assembling the overhangs

Build the overhangs for the shed from 2×4 lumber. You can adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings.

Fitting the overhangs

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

Fitting the roof sheets

Fit the 3/4″ plywood sheets to the roof of the lean to shed. Align the edges with attention and insert 1 5/8″ screws, every 8″ along the rafters.

Side roof trims

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

Front and back roof trims

Cut the trims for the front and back of the shed roof. Align the edges and insert 2″ nails to lock the trims 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.
