Canary Wharf is a major business district in east London, within the London Borough of Tower Hamlets. It is one of the United Kingdom's two main financial centres â along with the City of London â and contains many of Europe's tallest buildings, including the second-tallest in the UK, One Canada Square.[1][2]
Trusses and rafters are both assembled ahead of being installed onto the roof. Trusses are assembled in a factory using pre-engineered structures and joints. On the other hand, rafters are assembled at the construction site. As trusses are assembled in a factory, a lot of time can be saved.
A normal gable overhang is usually 12 to 24 inches wide. It is made up of rafters that are called fly rafters and are constructed of either 2x or 1x lumber. The fly rafters are usually one size smaller in width than the rafters used to frame the main roof. If the roof was framed with 2x8'sthe fly rafters would be 2x6's.
