10×10 Gambrel Shed Roof Plans

by Ovidiu


This step by step diy project is about 10×10 barn shed roof plans. This article is PART 2 of the 10×10 barn shed, where I show you how to assemble the trusses and how to make the small storage loft. Make sure you check out the rest of the project, so you learn how to build the frame of the shed and how to make the double front doors. 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.

Building a 10×10 Gambrel Shed Plans



Build the rafters for the barn shed from 2×4 lumber. Make 22.5 degree cuts to both ends of the rafters. You can use a miter saw so you make the repetitive cuts easily.



Assembling the trusses is a straight-forward process, once you have cut all the rafters to size and shape. Lay the rafters on a level surface and then secure them together with 1/2″ plywood gussets. Use 1 5/8″ screws and waterproof glue to lock the components together tightly.



Fit the trusses to the top of the barn shed, making sure you place them every 16″ on center. Use a spirit level to plumb the trusses and then lock them into place with screws or metal connectors.



Build the bottom rafters for the barn shed from 2×6 lumber. Make 22.5 degree cuts to both ends of the rafters.



Fit the bottom rafters to the top of the barn shed, as shown in the diagram. Align the edges at both ends and then secure them into place with 2 1/2″ screws. Leave no gaps between the components for a neat result.



As you can imagine, you can easily adjust the size and the location of the loft. Cut the 3/4″ plywood panels at the right dimensions and then secure them into place with 1 5/8″ screws, every 8″ along the structure.



Build the supports for the gambrel end panels from 2×4 lumber. Make a 22.5 degree cut to the top of the supports using a miter saw. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ screws.



Cut the panels for the barn shed at the right dimensions and shape and then lock them to the front and to the back of the shed, using 4d nails. Align the edges flush and then leave no gaps between the panels.



Assemble the overhangs for the barn shed from regular rafters and 2×4 blockings. You easily adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings. Add waterproof glue to the joints for a neat and professional result.



Use 3/4″ plywood panels for the roof of the barn shed. Cut the components at the right dimensions and then lay them to the roof of the barn shed using the pattern from the image. Use 1 5/8″ screws to lock the panels into place, every 8″ along the rafters.



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.



Use 1×6 lumber for the roof trims. Make a 22.5 degree cut to both ends of the trims and smooth the cut edges with sandpaper.



Attach the trims to the roof of the barn shed and lock them into place with 1 1/2″ brad nails. Leave no gaps between the trims for a neat result.



Make sure you take a look over PART 1 and PART 2 of this 10×10 shed project, so you learn how to build the frame of the shed, as well as the double doors.



Don’t forget to take a look over PART 1 and PART 3 to learn how to build the frame of the shed, as well as how to frame the double front doors. This is a straight forward project, so you shouldn’t feel intimidated by its complexity. After you get the building permit (if required) you can start the project.

In your 10’x10′ gambrel roof plan you list 2″x4″x8′ boards twice (60 + 11) in the summary list. But don’t list any 10′ 2x4s. Is this an error? I know I could figure this out when building the shed … But it would make ordering the wood ahead of time easier and it seems odd to ask for the same dimension wood twice.

Ovidiu -

Thank you for letting me know. You don’t need 2x4s at 10′. I ve updated the list.

Brandin H -

I was reviewing the material list and it states that some T1-11 siding will be needed under letter K, but in the list of materials below there is no mention of T1-11. Is this amount covered in the 10 sheets from Part 1, or does additional need to be added here? This can be figured out if I sit down and do the math, but thought I would verify with you.

Brandin H -

Scratch my last comment. I had the wrong sheet that I was looking at. I see that 5 sheets of T1-11 on the inventory list for this portion of the install. Thanks for putting this together!!

Dean Terencio -

I built the Marco Series 10′ x 10′ Gambrel 16798, run code 09309-1 July 2010. Would like to build another but have misplaced the plans.
Will you please send me another set of plans via pdf?
Thank you
