16×16 Gable Shed Roof Plans

by Ovidiu


This step by step diy project is about 16×16 gable shed roof plans. This article is PART 2 of the 16×16 shed project, where I show you how to frame the roof. 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.

16×16 Gamble Shed Roof Plans



The first step of the roof project is to build the rafters for the trusses. Cut both ends of the 2×6 as shown in the diagram. In addition, you need to make birds mouth cuts to the rafters, so that they fit to the top plates in a proper manner.



Lay the rafters on a level surface and attach the bottom components. Make sure you make 60 degree cuts to both ends of the bottom rafters and then secure it to the rafters with metal plates or 1/2″ plywood gussets. Leave no gaps between the components for a neat result.



Fit 2×4 supports to the trusses that are placed at both ends of the roof. You need to install these supports so the siding panels can have a frame to lock to.



For the rest of the trusses, you can fit just a few supports, as shown in the diagram.



Fit the trusses to the top of the 16×16 shed and space them 24″ on center. Use a spirit level to plumb the trusses and then secure them to the top plates of the shed with metal hardware and screws.



Attach the 5/8″ T1-11 siding to the front and to the back of the shed. Leave no gaps between the panels and then secure them into place with 1 5/8″ screws or 4d nails.



Assemble the overhangs from 2×6 lumber. As you can easily notice in the diagram, you can to adjust the width of the overhangs to suit your needs.



Fit the overhangs to the front and back of the 16×16 shed. Align the edges with attention and then lock them into place with 3 1/2″ screws, after drilling pilot holes.



Attach the 3/4″ plywood sheets to the roof. Cut the panels at the dimensions indicated in the plans and then secure them to the rafters with 1 5/8″ screws, every 8″. Leave no gaps between the sheets for a professional result.



Attach 1×8 trims to the sides of the shed. Use 1 1/2″ brad nails to secure the trims into place tightly. Align the edges flush for a professional result.



Cut the roof trims from 1×8 lumber. Make 30 degree cuts to both ends of the trims and then smooth the edges with sandpaper.



Attach the trims to the front and back of the shed roof. Align the edges and then secure them into place with 1 1/2″ brad nails.



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. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Afterwards, attach the asphalt shingles to the roof, starting with the left bottom side of the roof. Read the manufacturer’s instructions to understand how to install the shingles into place properly.



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.

Hello, would the roof of your 16×16 shed plans be called a 5/12 pitch?

Also, can you use the same plans for a sunroom and just add headers and windows?

Thanks so much!

Ovidiu -

No. This roof has a 7/12 pitch. If you want a sunroom, I have some plans for that: http://myoutdoorplans.com/shed/greenhouse-shed-plans/
