15×12 Outdoor Pavilion Roof Plans

by Ovidiu

 

This step by step diy woodworking project is about a 15×12 outdoor pavilion roof plans. This is PART 2 of the pavilion project, where I show you how to build the gable roof with a 6:12 pitch, made out of 2×6 rafters, covered with 3/4″ plywood and asphalt shingles. The pavilion has 1×8 trims on all sides for extra attention to details. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Premium Plans for this project available Here. Check out the Shop, as well, for full list of Premium Plans.

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 15×12 pavilion roof

Rafters

Rafters

Use 2×6 lumber for the gable roof rafters. Use a circular saw to make the 26.5 degree angle 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

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. The dimensions shown in the diagram represent the distance between the rafters. 

Use rafters ties to lock the rafters to the beams. Insert 1 1/2″ structural screws for the rafter ties. Use 2 ties for each rafter, one at each end. Make sure you buy rafters for 2×6 beams.

Fitting-the-roof-sheets

Fitting-the-roof-sheets

Use 3/4″ 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. 

Start installing the sheets from the bottom left to the right of the roof. Then install the next row of sheets, starting from the left as well.

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

Fit the 1×8 trims to the front and back of the pavilion. Make sure you make a 26.5 degree cut to one end of the gable end trims. 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.

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.

Don’t forget to take a look over PART 1 of the project, so you learn how to build the frame of the wide pavilion. If you follow this tutorial you will build a beautiful pavilion with a gable roof and generous overhangs on all sides. You can change the roof pitch if you want a different design.

You can adjust the height of the posts to suit your needs. You can customize this pavilion to suit your needs with minimal modifications. For example, you can attach railings to the pavilion or your can install tongue and groove boards to the interior side of the roof structure.
