14×20 Backyard Pavilion – Gable Roof Plans

This step by step diy woodworking project is about a 14×20 backyard pavilion gable roof plans. This is PART 2 of the large rectangular pavilion project, where I show you how to build the roof and how to attach the decorative trims. The roof pitch is 8:12. You can adjust the angle of the roof to suit your needs and your local codes. This pavilion makes for the perfect addition to your backyard.  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.

How to build a 14×20 gable pavilion roof

Rafters—gable-pavilion

Use 2×6 lumber for the rafters. Use a miter saw to make the cuts to the boards. Smooth the edges with sandpaper. Make the notches to the rafters, as shown in the plans. Mark the lines before doing the cuts.

Fitting-the-rafters

Fit the rafters to the top of the pavilion, using the information from the diagram. It is important to space the rafters properly (every 24″ 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 1/2″ structural screws for the rafter ties.

Fitting-the-roof-sheets

Use 1/2″ plywood for the roof of the 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.

Gable-end-roof-trims

Fit 1×8 trims to the sides of the pavilion. Align the edges with attention and insert 2″ nails to lock them into place tightly.

Side-roof-trims-plans

Fit the 1×8 trims to the front and back of the pavilion. Lock them into place with 2″ nails.

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.

14×20-pavilion-plans—assembled

Once assembled, this large backyard pavilion makes for a nice place that gives you shade during the hot summer days and a roof over your head when it gets stormy. This simple gazebo has the perfect size so you can serve dinner with family and friends.

How-to-build-a-14×20-pavilion

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.

Front view

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint / stain to enhance the look of the pavilion and to protect them from the elements.

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 1000) HERE.
