This step by step diy woodworking project is about a 16×18 outdoor pavilion roof plans. This is PART 2 of the compact rectangular pavilion project, where I show you how to build the roof and how to attach the decorative trims. The roof has a 30 degree slope, which you can adjust to suit your needs and the local building codes. 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 16×18 pavilion roof
Use 2×6 lumber for the rafters. Use a miter saw to make the 30 degree cuts at both ends of the beams. Smooth the edges with sandpaper.
Make the notches to the rafters, as shown in the plans. Mark the lines before doing the cuts.
Fit the rafters to the top of the wooden pavilion, using the information from the diagram. It is important to space the rafters properly (every 16″ on center), otherwise you won’t be able to attach the roofing sheets. Use rafters ties to lock the rafters to the beams.
Use 1/2″ or 3/4″ plywood for the roof of the backyard pavilion. Cut the sheets at the right dimensions and then lay them to the top of the pavilion. Leave no gaps between the sheets and then insert 1 5/8″ screws, every 8″ along the rafters, so you can secure them into place tightly.
Fit 1×8 trims to the sides of the outdoor pavilion. Align the edges with attention and insert 2″ nails to lock them into place tightly.
Fit the 1×8 trims to the front and back of the garden pavilion. Make the angle cuts to the trims before locking them into place with 2″ nails.
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.
Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-200 grit sandpaper and remove the residues with a damp cloth. Apply a few coats of stain or paint to enhance the look of the pavilion. Make sure you take a look over PART 1 of the project, where I show you how to build the frame of the pavilion.
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. This is a great addition to your property as it will create a nice shade where you could serve dinner and hang out with your friends.
Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Make sure you take a look over the rest of my pergola/gazebo/pavilion plans HERE. See all my free woodworking plans (over 1500) HERE.
