How to install rafters for a carport roof

Overview

Following on from our How to install post and beams for a carport video, find out how to attach the rafters to your carport roof frame. We'll show you how to mark out where the rafters should go and how to install them flush against the perimeter beams.

Steps

1Mark out where your rafters will go

Before you start, brace your carport framework for extra strength while you're working with timber. Mark out the spacings for your rafters on the beams according to your plans and how many rafters you'll be using. Make the marks on both beams that will connect your rafters so that everything lines up.

2Put up your rafters

When you put up your rafters, make sure that they are nice and flush against the perimeter beams when you nail them in. A good tip is to leave one side of the rafters lower than the other. This will mean that the flat ceiling will effectively drain off water. Pre-drill your holes before you screw batten screws in so they are all even and neat.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer.
