8×10 Gambrel Shed Roof Plans

by Ovidiu


This step by step diy project is about 8×10 gambrel shed roof plans. This is PART 2 of the small barn shed where I show you how to frame the roof and how to fit the decorative trims. You can even frame a small loft to the gambrel shed, so you can increase the storage space. 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 gambrel shed roof



The first step of the project is to build the trusses for the gambrel shed. Cut the rafters from 2×4 lumber, by making 67.5 degree cuts to both ends, as shown in the diagram.



Lay the rafters on a level surface, leaving no gaps between them. Afterwards, use 1/2″ plywood to make the gussets and lay them over the joints. Insert 1 5/8″ screws to secure the gussets into place tightly.



After assembling the trusses you need to fit them to the top of the barn shed. Place the rafters equally-spaced, every 24″ on center and then lock them to the top plates with rafter ties. Use a spirit level to plumb the trusses.

Fit 2×4 supports to the front and back gambrel end panels. Drill pocket holes at both ends of the supports and lock them into place with 2 1/2″ screws.

Front and back gambrel panels

Cut the gambrel end panels from T1-11 siding and then fit them to the front and to the back of the barn sheds. Leave no gaps between the sheets and then secure them into place with 6-8d nails.

Fitting the roofing sheets

Fit the 3/4″ plywood sheets to the top of the barn shed. Cut the plywood sheets at the right dimensions and then secure them into place with 1 5/8″ screws, every 8″ along the rafters.

Front and back trims

Front and back trims

Use 1×6 lumber for the front and back roof trims. Make 67.5 degrees to both ends of the trims and then secure them into place with 2″ nails.

Fitting the roofing

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.

I see that when reinforcing the trusses with gussets, it says to use 1/2 plywood. That is not in the materials list that I can see.
