14x18 Gable Shed Roof Plans

This step by step diy woodworking project is about a 14×18 gable shed roof plans. This is PART 2 of the large storage shed project, where I show you how to build the gable roof. This roof has a 5:12 pitch, but you can adjust it super easily. The shed features generous overhangs to protect the structure from rain. 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 14×18 gable shed roof

Rafters-for-large-gable-shed

Use 2×6 lumber for the rafters. Use a miter saw to make the angle cuts at both ends of the rafters. Smooth the edges with sandpaper and then make the birdmouth cuts.

Bottom-chords—14×18-shed

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

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-14×18-shed

Fit the trusses to the top of the shed frame. Place the trusses every 16″ on center and plumb them with a spirit level. Use rafter ties to lock the trusses into place tightly.

Gable end panels

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.

Building the overhangs

Use 2×6 lumber for the overhangs. Cut the rafters and then lock them together with blockings. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings.

Fitting the overhangs

After assembling the overhangs you have to secure them to the gable ends of the shed. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws.

Roof-sheets

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.

Front and back roof trims

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

Side roof trims

Fit the 1×8 trims to the front and back of the shed, as well.

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.
