4×8 Attached Shed Roof Plans

This step by step diy project is about 4×8 attached roof plans. This is PART 2 of the free 4×8 attached shed plans, where I show you how to build the lean to roof and how to attach the siding sheets. Make sure you check the local codes and make adjustments to the plans, if required. 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. See all my Premium Plans HERE.

Building a 4×8 lean to shed roof

Top back wall frame

The first step of the project is to build the top frame for the shed. Cut the components from 2×4 lumber at the dimensions shown in the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center, for a professional result.

Fitting the top wall frame

Fit the wall frame to the top of the back wall. Align the edges with attention and plumb it with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2′ screws into the wall.

Rafters-for-4×8-shed

Use 2×4 lumber for the rafters. Mark the cut lines on the boards and then get the job done with a circular saw. Set the miter saw at 26.6 degrees.

Fitting-the-rafters

Fit the rafters to the top of the shed, every 16″ on center. Use rafter ties to lock the rafters into place tightly.

Side wall panels

Fit the T1-11 siding sheets to the sides of the shed. Align the edges and insert 6-8d nails, every 8″ along the framing.

Roof-sheets

Fit the 3/4″ plywood sheets to the roof of the shed. Align the edges with attention and insert 1 5/8″ screws, every 8″ along the framing.

Roof trims

Fit 2×6 trims to the sides of the roof. Fit 1×6 trims to the front of the shed. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws.

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.
