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.
2x4 rafters/roofing question... i helped a friend build his garage's roof, kinda of uncomfortable. he says lowes told him he could use 2x4 for rafters with 1/2 inches plywood for asphalt shingles. the rafters are 18 foot long without beams or trusses (garage 28x40).he's already got the 2x4 up for rafters and it's ready for laying plywood tomorrow.i told him plywood and asphalt shingles would be too heavy. he could get his money back for the plywood and do tin roof setup instead.he rafters are 18 foot long without beams or trusses (garage 28x40). he's already got the 2x4 up for rafters and it's ready for laying plywood tomorrow. i told him plywood and asphalt shingles would be too heavy. he could get his money back for the plywood and do tin roof setup instead.
