12×16 Lean to Shed – Roof Plans

Ovidiu 0 GapDice RANDOM PLAN

This step by step diy project is about diy 12×16 lean to shed roof plans. This is PART 2 of the lean to shed project, where I show you how to build the lean to roof for the 12×16 shed. Moreover, I have designed shed with many sizes so check them out, as well. Roof pitch is 4:12. 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.

Fitting the roofing

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 12″ piece for the top ridge. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.

Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Check PART 1 of the project to learn how to build the frame of the shed and PART 3 to learn how to build the door for the shed.
