Roof sheeting is used to support and protect a building’s roof, whether it’s a residential home or a commercial or industrial establishment. It helps distribute the load in case of snow and heavy rainfall and prevents the roof from sagging. It also provides insulation and soundproofing properties. Moreover, it helps in preventing leakages and prolongs the lifespan of a roof. In the long run, it will save homeowners and business owners money by cutting down on repair and replacement costs.

Various types of roofing sheets are available on the market today, each having its own set of pros and cons. It is important for consumers to carefully assess their specific needs and budget before buying any roofing sheets. In order to make an informed decision, they can also seek the assistance of a professional and experienced roofing contractor.

The most popular roof sheathing material is plywood. It is made of strips of wood that are glued together and compressed into flat 7/16″ sheets. Plywood is stronger than OSB, and it is less susceptible to shrinking and swelling as a result of exposure to moisture. It is a dense and durable material that can withstand high winds and torrential rains.

Another type of roof sheathing is OSB (oriented strand board). It is similar to plywood in that it is made of wood chips and strips that are glued and compressed into flat boards. OSB is a more economical choice than plywood, but it can suffer from moisture problems. When it gets wet, it may swell along the edges, creating “ghost lines” that show through the shingles. This issue is typically addressed by using OSB with a preservative treatment or by applying a moisture barrier at the time of installation.

When it comes to roof sheathing, it is critical that you follow local building codes and manufacturer’s installation instructions to ensure proper installation. Failure to do so can void the product’s warranty, and it can also create issues with your roofing materials. For example, plank sheathing that has gaps larger than 1/8″ will not be able to properly hold roofing materials and is susceptible to water penetration, which can lead to rot or structural damage in the home.

In addition to being an important structural component of the roof, roof sheathing is an excellent insulator. It reduces attic temperatures, improves moisture performance, and helps lower a house’s energy bill by keeping the indoor temperature cool. It is also fire resistant and can withstand strong winds, heavy rains, hail storms, and even wildfires. This makes it an ideal option for backyard sheds, garden buildings, garages, and household cladding. It is also lightweight, anti-corrosive, and affordable. These qualities make it a popular roofing material for residential and commercial applications.
