8×16 Lean to Shed Roof Plans

This step by step diy project is about 8×16 shed roof plans. This is PART 2 of the shed project, where I show you how to build the lean to roof for this garden shed. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

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.

Building a 8×12 shed roof plans



First of all, you need to make the rafters for the lean to shed. As you can easily notice in the plans, you need to mark the cut lines on the beams and get the job done with a circular saw. Smooth the edges with sandpaper, for a neat result.



Fit the supports to the sides of the shed.



Fit the rafters to the top of the shed, making sure you space them every 24″ on center. Use metal ties, to secure the rafters into place with attention.



Optionally, you can fit 2×3 blocking between the rafters, so you seal the shed. Drill pocket holes at both ends of the blockings and insert 2 1/2″ screws into the rafters.




Fit the 2×4 supports to the sides of the roof. Drill pocket holes at both ends of the supports and insert 2 1/2″ screws to lock them to the frame of the shed.



Fit the siding panels to the sides of the roof. Use 4d nails to lock the panels into place.



Use 3/4″ tongue and groove plywood sheets for the roof of the barn shed. Drill pilot holes and insert 1 5/8″ screws, every 8″ along the rafters. Leave no gaps between the tongue and groove sheets.



Attach 2×6 trims to the sides of the roof and lock them into place with 2 1/2″ screws. Attach 1×6 trims to the ends of the rafters. Align the trims with attention and 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. 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.



This shed is roomy enough for lots of items, so if you are looking for a cheap and straight-forward way of keeping your things protected from the elements, this shed is one good choice. Don’t forget to take a look over PART 2 and PART 3 to learn how to build the roof for the shed, as well as how to frame the double front doors.
