Building a shed often entails finishing the structure with proper framing for the roof, but it can be a tricky part in your weekend project with a variety of ways to attach the rafters and trusses to the top plate. Before anything else, it’s best to understand your materials first to help you identify the best way to support them later on.
What are Trusses and Rafters?
Trusses and rafters are materials that make up the roof structure, and while they have similarities, there are distinct functions that impact your choice of attachment to the top plate. For one, trusses come as a pre-assembled structure that you need to install onto the shed’s frame.
There are two lengths of lumber that make up the upper edge of the truss, while the bottom chord bridges both ends of the top chord, filling with webwork in the middle area to strengthen its support. This feature makes it significantly more durable than rafters, making it the best option for those looking to build sheds for the long haul.
Rafters, on the other hand, are wooden beams that connect the roof’s peak to the top plate of the supporting walls. The rafters are installed individually to form two main outer beams, though it’s better for smaller structures since it can provide an open ceiling for a more spacious feel.
Since rafters are the most common choice for small home sheds, we’ll be focusing on different ways to attach beams to your shed’s top plate.
Different Methods to Attach Rafters to the Top Plate
A classic choice for securing your rafters is toenailing involves connecting the rafter to the top plate using nails driven into the beam and the wall cap. It is drilled at an angle on different ends of the rafter, which prevents the nails from loosening from the roof’s weight.
2. Hurricane Tie
Toenailing can be tricky even for seasoned woodworkers since it involves estimating angles and the right depth. Hurricane tie, on the other hand, offers a more secure joint, all while being more straightforward to install.
It uses joist hangers that cradle the rafter using the metal plate, while the holes surrounding the plate make it easy to nail down accurately.
3. Ridge Rafter Connector
Another easy way to attach the rafters to the ridge beam is to use a ridge rafter connector to connect them to the roof’s peak. It’s the best choice for those working with a lean-to shed as the connectors can latch onto the top plate’s lip using galvanized nails.
There are already pre-drilled holes, making it easy to determine where and how deep it should go.
The Bottom Line
There are various ways to attach your rafter to the top plate of your roof, but the list above shows some of our go-to methods that offer a straightforward process for beginners. Toenailing is arguably the easiest choice, but hurricane ties is a favorite as it provides superior strength.
