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 15×15 pavilion roof
Use 2×6 lumber for the rafters. Use a miter saw to make the 26.5 degree cut to one end of the rafters. Mark the cut lines to the beams and and get the notches cut, as shown in the plans. Smooth the edges with sandpaper.
Fit the rafters to the top of the 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 1/2″ structural screws for the rafter ties.
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.
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.
Cut the gable roof trims with a miter saw. Fit the 1×8 trims to the front and back of the pavilion. Lock 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.
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.
