for a roof spanning 14.4m x 8.4m on a residential house, is it better to use timber trusses or steel trusses? the priorities are; ease of construction, price, insulation (want to keep heat out, i am in a tropical country), durability, flexibility, minimal load on foundations.please help. thank you :-)

How about another option - Steel Re-inforced Concrete Beams. Beam planks would span 8.4 metres but to keep the cost down have an I beam support at 4.2m. Concrete is great. It goes on quick, is sound proof, (very nice when it rains or for road traffic), can have gravel laid on top to act as a heat sink for winter sun and can be covered with normal roof steel if you want to hide it. Its also rust and borer free. While you would need good supports for the front and back, although with an I beam you can have a floating front, it is not much more than what is required for a wooden top. Design it right and your roof could be a future floor for the next addition.
