16×16 Barn Shed Roof Plans

This step by step diy project is about 16×16 gambrel roof plans. This is PART 2 of the shed project where I show you how to build the barn style roof for the 16×16 garden shed. This shed has overhangs to the front and back. In addition, you can easily add a loft to the barn shed, for even more 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 16×16 barn shed roof

Building-the-rafters

The first step of the shed roof project is to build the rafters for the trusses. In order to get a professional result, you need to use a miter saw and to make 22.5 degree cuts to both ends of the 2×4 beams.

Fitting the gussets

Use 1/2″ plywood for the joints, so you can reinforce the rigidity of the trusses. Cut the gussets at the right dimensions and then secure them to the rafters with 1 5/8″ screws.

Fitting-the-trusses—16×16-barn-shed

Fit the trusses to the top of the shed and then plumb them with a spirit level. Use rafter ties to lock the trusses into place tightly. Place the trusses every 24″ on center for a professional result.

Gambrel end supports

Use 2×4 lumber for the gambrel end supports. Make 22.5 degrees to the top of the supports. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ screws.

Gambrel end panels

Make cuts to the siding sheets so you can lock them to the front and to the back of the barn shed. Align the edges flush and then leave no gaps between the sleets. Use 1 5/8″ screws to lock the T1-11 siding sheets into place tightly.

Building the overhangs

Build the overhangs for the front and the back of the shed from 2×4 lumber. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings. You can adjust the size of the blockings to suit your needs.

Fitting the overhangs

Fit the overhangs to the front and to the back of the shed. Align the edges flush. Drill pilot holes through the overhangs and insert 3 1/2″ screws to lock them into place tightly.

Fitting the roofing sheets

Cut and fit the 3/4″ plywood sheets to the roof of the gambrel shed. Align the edges with attention and insert 1 5/8″ screws every 8″ along the rafters, so you can lock them into place tightly. Leave no gaps between the sheets for a professional result.

Roof trims

Fit the 1×6 decorative trims to the front and to the back of the gambrel shed. Make the angle cuts and then secure them into place with 2″ nails.

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.
