Live and dead load for residential roofs in virginia.
On a roof with a slope greater than 4 to 12 the live load limit is typically adjusted downward from 20 psf to 15 psf to allow for the relatively greater dead load on the steeper roof.
3 3 dead loads dead loads consist of the permanent construction material loads comprising the roof floor wall and foundation systems including claddings finishes and fixed equipment.

They must also be used when maintaining or repairing an existing building or renovating or changing the use of a building or structure.
The roof is designed for the roof live load not more than 20 psf or the snow load whichever is greater.
0 9d 1 0e effect or 0 9 when resisting the load when permanent.
For secondary wall members supporting formed metal siding the design wind load deflection shall not exceed l 90.
For secondary roof structural members supporting formed metal roofing the live load deflection shall not exceed l 150.
For structural roofing and siding made of formed metal sheets the total load deflection shall not exceed l 60.
It is important to list live load dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength.
Where uniform roof live loads are reduced to less than 20 psf 0 96 kn m 2 in accordance with section 1607 12 2 1 and are applied to the design of structural members arranged so as to create continuity the reduced roof live load shall be applied to adjacent spans or to alternate spans whichever produces the most unfavorable load effect.
