Trusts, slopes and cornices are the important parts of the roof. Their design, placement and materials alter the quality of the roof and its durability. Also, the visual effect of the house will be better if the roof is nicely constructed and matched to the house and the other conditions in the surroundings. The roof trusses are the firm framework. The roof trusses have generally unified dimensions. For example, for a residence they should be lumbers with the following dimensions: 2″ x 4″ or 2″ x 6″. The trusses are placed on expansion 20′ to 32′.
