This step by step woodworking project is about how to build a gazebo roof. Building a rectangular gazebo roof is a complex project, as it involves a lot of cuts, but any person with basic woodworking skills can get the job done, if the right plans are used. You can adjust the size and the shape of the roof, as to fit your needs and tastes. Follow the general instructions and get the job done in one weekend.
Building a roof for a rectangular gazebo is a complex task, as it involves many cuts and a lot of measurements. In addition, you need to ask another person to hols the components in place, after aligning them at both ends, while you drive in the screws. Follow the building codes and use quality materials, if you want to get a professional result. It is essential to use weather-resistant lumber that is in a good condition and perfectly straight.

Building a gazebo roof
Top Tip: Building a rectangular gazebo is one of those projects that will add value to a garden. After making the frame of the gazebo, you should build the roof and install the shingles.
How to Build a Gazebo Roof
The first step of the project is to install the top ridge. As you can see in the image, you need to cut the middle rafters at 45º, using a miter or a circular saw. Align the components with great care, if you want to get a professional result.
Use a spirit level to check if the top ridge is horizontal. Drill pilot holes trough the rafters before driving the 5″ galvanized screws, to prevent the wood from splitting.
Continue the project by installing the hip rafters. As you can see in the image, you need to cut both ends of the rafters at 61.5º (make 28.5 degree cuts). Use a circular saw or a miter saw to get the job done in a professional manner. An then cut the top of the rafters at 45 degrees on the middle (so two 45 degree cuts on the middle) creating a triangle.
If you use a ladder, make sure you place it on a sturdy surface. It is also essential to secure the rafters tightly into place, otherwise the roof structure might not be enough rigid.
The next step of the woodworking project is to install the intermediate rafters. As you can see in the image, you need to cut the rafters at angle, otherwise they might not fit into place properly. Cut both ends of the components at 48.5 degrees. Then you need to cut the top of the rafters at 47 degrees, so they can fit to the hip rafters properly.
Top Tip: On the other hand, it is essential to place the rafters every 24″. otherwise you won’t be able to fit the roofing sheets accurately. Pre-drill the rafters at both ends, before inserting the screws into the hip rafters.
Continue the project by fitting the intermediate rafters on the other sides of the roof. Cut the ends of the rafters at 57º, otherwise they might not fit into place properly. Place the rafters every 24″, in order to support the weight of the roof efficiently. For the small rafters placed at both ends of the front and back of the roof, you need to make one more cut to the top, so they can fit to the hip rafters. Cut them at 29.5 degrees.
Build the rest of the rafters in the same manner and fit them to the opposite side of the rectangular gazebo. Align the rafters at both ends and drive the screws in the top plates.
The next step of the outdoor project is to fit the roofing sheets. As you can see in the image, you need to cut the 3/4″ plywood sheets at the right size before attaching them to the rafters. Drill pilot holes trough the plywood and insert 1 1/4″ galvanized screws into the rafters, every 8″.
Cover the roof with tar paper, making sure the strips overlap at least 2″. Use staples to secure the roofing felt into place, every 6″.
One of the last steps of the project is to enhance the appearance of the rectangular gazebo. Add 1×4 trims to the end of the rafters, if you want to get a professional result. Align the trims at both ends and lock them to the rafters with 1 1/4″ finishing nails.
Top Tip: Use a spirit level to check if the trim are horizontal. In addition, you could cut the ends of the trims at 45º, otherwise they might not fit together easily.
Last but not least, you have to install the asphalt shingles. Fit the starting course before installing the asphalt shingle tabs. Secure them into place with roofing tacks. Cut the tabs into three components, in order to cover the hips.
Top Tip: Fill the holes with putty and let it dry out for several hours, before sanding the surface with 120-grit sandpaper. Vacuum the residues and apply several coats of protective paint.
