One integral roofing component is the roof decking—often overlooked yet paramount for the structural integrity of your roof. Serving as the base over which everything else is placed, the proper selection, maintenance, and understanding of roof decking types are essential considerations for homeowners looking to invest in a new roof. In this blog, LePage and Sons Roofing LLC delves into what roof decking is, the various types available, and how to choose the right one.
Roof decking is the layer between the primary structural components of your roof—the trusses and joists—and the insulating layer and waterproofing material. It’s where your shingles or other roofing materials are directly laid. The durability, longevity, and overall performance of your roof heavily depend on the quality and type of decking used. Thus, selecting the appropriate decking material can significantly affect your roof’s lifespan.
There are mainly two types of roof decking materials commonly used: plywood and oriented strand board (OSB). Plywood decking is made from thin sheets of wood veneer, making it strong and durable. It is preferred for its resistance to moisture and its ability to hold fasteners securely. On the other hand, OSB is made from interwoven strands of wood bonded with adhesive. It is generally more cost-effective than plywood and has become increasingly popular due to its strength and dimensional stability.
Choosing the right type of decking involves considering several factors, including your budget, the architectural style of your home, and the local climate. Plywood might be a better choice for homes in areas that encounter frequent, heavy rainfall or high humidity due to its moisture resistance. Alternatively, for homeowners looking for a more economical option without compromising on durability, OSB could be the ideal choice.
Regular maintenance and inspection are vital to ensuring the longevity and integrity of your roof decking. Look for signs of moisture damage, such as mold or rot, which can compromise the structural integrity of your roof. Additionally, sagging areas or noticeable dips in the roof could indicate weakened decking that needs repair or replacement. Be sure to consider scheduling annual inspections with a reputable roofing contractor to detect potential issues early on and maintain the health of your roof decking.
Understanding when to replace your roof decking is crucial. It’s not always necessary to replace the decking when getting a new roof, but certain signs shouldn’t be ignored. If significant moisture damage, rot, or mold is discovered during a roof inspection, replacing the affected areas or the entire decking might be necessary. Moreover, if the decking doesn’t meet current building codes or shows signs of structural weakness, a replacement will be required to ensure the safety and integrity of your home.
