10×8 Gable Shed Roof Plans

This step by step diy project is about 10×8 shed roof plans. This is PART 2 of the small garden shed plans, where I show you how to build the gable roof. The shed has an average slope so it can drain the water properly. 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 10×8 shed

Building-the-trusses

First of all, you need to build the trusses for the shed. Cut the rafters from 2×4 lumber and make the angle cuts, as shown in the diagram. Lay the rafters on a level surface and leave no gaps between them.

Truss supports

Build the middle truss support from 2×4 lumber. Use a circular saw to make the angle cuts to the support and then fit it into place. Attach the 1/2″ plywood gussets over the joints, so you reinforce the rigidity of the trusses. Alternatively, you can use metal gussets. Align the edges flush and insert 1 5/8″ screws, so you lock the gussets into place tightly.

Fitting-the-trusses

Fit the trusses to the top of the shed and place them every 16″ on center. Plumb the trusses with a spirit level and secure them into place with rafter ties.

Gable end panels

Cut the gable end panels from T1-11 siding and then fit them into place. Align the edges flush and insert 6-8d nails, every 8″ along the framing.

Assembling the overhangs

Build the front and back overhangs from 2×4 lumber. Cut the components at the right dimensions and then lock them together tightly with 3 1/2″ screws. The overhangs protect the walls from water damage and they also add character to the project. Align the edges flush, so you secure them into place tightly.

Fitting the overhangs

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

Roof sheets

Fit the 3/4″ plywood sheets to the roof of the shed. Align the edges flush and insert 1 5/8″ screws along the rafters, every 8″. Leave no gaps between the sheets for a professional result.  Drill pilot holes and insert 1 5/8″ screws, so you lock them into place tightly.

Side roof trims

Fit the 1×6 trims to the sides of the shed. Align the edges and insert 2″ nails, so you can secure them to the end of the rafters.

Front and back roof trims

Cut the side roof trims from 1×6 lumber. Make angle cuts to the rafters and then secure them into place with 2″ brad nails.

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.
