Flat Roof Plans for a 10×12 Shed

This step by step woodworking project is about 10×12 roof plans. This is the PART 2 of the 10×12 flat roof shed, where I show you how to build the 3 degree sloped roof. This shed has a modern look, so if you are into that make sure you read my instructions to see what my plan is all about. Remember that this shed is suitable for mild climates, so if you live in an area with snow, follow these shed plans. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

10×12 Shed Roof – DIY Plans

Rafters – 10×12 flat roof shed

Use 2×4 lumber for the rafters. Mark the cut lines on the beams and then get the job done with a circular saw. Smooth the edges with sandpaper.

Fitting the rafters – 10×12 shed

Fit the rafters to the top of the shed. Place the rafters every 24″ on center, equally spaced, as shown in the diagram. Drill pilot holes and insert 3 1/2″ screws to lock the rafters into place tightly. Alternatively, you can use rafter ties to lock the trusses to the plates.

Side wall supports

Use 2×4 supports for the sides of the roof. Drill pocket holes at insert 2 1/2″ screws to secure them into place tightly.

Side wall siding sheets

Use T1-11 siding sheets for sides of the shed. Use 8d nails to secure the sheets to the wall frames.

Side overhangs – 10×12 shed

Use 2×6 lumber for the overhangs. You can adjust the size of the overhangs according to the size of the blockings.

Fitting the side overhangs

Fit the overhangs to the front and back of the shed. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws.

Fitting the roof sheets

Fit 3/4″ plywood sheets to the roof of the shed. Align the sheets with attention, making sure you leave no gaps between them. Insert 1 5/8″ screws to lock the sheets into place, every 8″ along the rafters.

Side roof trims

Use 1×8 lumber for the side roof trims. Use 8d nails to secure the trims into place.

Front and back roof trims

Fit the trims to the front and back of the shed roof.

Fitting the roofing – 10×12 flat roof shed

Cover the roofing sheets with tar paper. Install the tar paper starting with the bottom of the roof and make sure the strips overlap for at least 2″. Install the shingles starting with the left- bottom of the roof, after fitting the starting course. Use roofing tacks to secure the shingles into place.

Front door – 10×12 shed

Use 2×4 lumber for the door frame. Assemble the door frame with 2 1/2″ pocket screws and then attach the T1-11 siding panel with glue and nails.

Door jambs – 10×12 flat roof shed

Attach the 2×4 jambs around the door opening. Align the edges flush and insert 2 1/2″ screws to secure the jambs into place tightly.

Attaching the door to the shed

Fit the door to the opening and align the edges flush. Use hinges to attach the door to the jambs. Install a latch.

Window trims – 10×12 flat roof shed

Fit the trims around the window.

10×12 Shed with a Flat Roof Plans

This shed is ideal if you need storage space but you have a narrow backyard. Make sure you choose a color that matches the style of your backyard. The paint will also protect the shed components from the elements. Make sure you take a look over PART 1 of the project, so you learn how to build the frame for the shed.
