Roof Sheeting Wood

Osb is lightweight relatively inexpensive and strong enough to resist bending or breaking should someone walk on the roof.

Roof sheeting wood.

With edge support and the same snow load 3 8 inch osb can be used. A strong resilient roof is a home s first line of defense when the roof deck is exposed to weather. Plywood is made with three or more layers of thin wood glued together with the grain alternating. In the u s roof sheathing is almost always composed of wood usually osb oriented strand board or plywood.

Typical types of wood used for roof sheathing are oriented strand board known as osb and plywood the most popular being osb. Wood is an excellent insulator and in moderate climates no additional rigid insulation on the roof is necessary. Roof sheathing or decking is one of those elements. Zip system roof assembly combines our revolutionary integrated sheathing and flashing tape or liquid flashing to provide a sealed roof for protection against moisture intrusion during construction or if high winds strip the roof covering away.

At the top of our game. Before lumber companies began selling osb the standard choice for sheathing a roof with a 24 inch rafter spacing was 1 2 inch cdx plywood the letters cdx indicate that it is construction grade. It is typically made in 4 by 8 foot sheets although longer panels are available for special purposes. The traditional way to lay wood shakes and shingles on spaced sheathing was ideal for wood roof longevity but it has largely fallen by the wayside.

Roof sheathing is the material that goes on top of your roofing structure including the trusses and beams that the roofing system is constructed on. The trusses and beams of the roof give the roof its initial pitch and structure and then the sheathing is applied so the actual underlayment and roof covering can be applied. Sheets of 7 16 inch thick with no edge support can be used in an area where the snow load is 30 pounds per square foot.
