As long as the plywood under the shingle roof is in good condition this way can provide many benefits.

Osb over existing sheet metal roof.

Osb comes in 4 by 8 foot sheets as does plywood but the manufacturing process allows the production of longer and wider ones. From the 2012 ibc international building code table 2304 6 1 over framing spaced 24 inches on center 7 16 osb fastened with 8d common nails six inches on center at the edges and in the field will support a maximum design wind speed vult of 110 mph miles per hour in exposure b or 90 mph in exposure c. Avoid butting osb panels tightly leave a 3 mm 1 8 inch gap between the osb panels to allow for expansion. Open spaces form between the once tightly fitted.

When the steel roofing can t carry the load other shear carrying materials such as 7 16 osb may be added to the assembly. Roof trusses must be dry when sheathing a roof with osb to prevent mold growth in the roof and coverage gaps as the trusses dry and shrink. Thicknesses range from 5 16 to 3 4 inch and the proper one to use. Today a shiplap roof is usually 60 years old.

This is by far the most common way to install a metal roof. Why re sheet over shiplap. In the case above the shear forces in the last 12 foot bay at each end of the roof have had osb placed between the roof purlins and the steel roofing. Table 2304 7 3 gives the 7 16 osb the ability to carry a roof live load of 40 psf pounds per square foot when spanning the same 24 inches.

If there are gutters installed on the eaves the eave flashing should be installed to overhang the lip of the gutter by about 1 2 inch. Osb is widely used as roof decking material. Oriented strand board commonly referred to as osb is a type of engineered lumber similar to particle board formed by adding adhesives and then compressing layers of wood strands. 3 install 1 4 purlins down over the shingles before installing the metal roof the third way to install a metal roof over shingles is by applying 1 4 purlins over the shingle roof.

Place corner pieces where panels will meet bends at the edge of the roofing. Stagger the panels over the roof with 2 supports between panel ends. After the 1960s the predominant residential roofing substrate became 1 2 cdx plywood.
