What is the Best Roof Decking Material?
To begin with, let’s start with an introduction to what roof decking actually is. The roof deck is the material between the structural components, or trusses and joists, and the insulation and weatherproofing layers, also known as the roofing materials or layers. The roof deck is the section of the roof onto which everything else is placed. That means that the roof deck needs to be incredibly strong and sturdy, ready to take the weight of the other roofing materials, and the impact of weather events.
There are different types of roof deck material. Each roof deck material serves a contrasting need based upon how much weight it needs to carry. The various types of roof decking material include steel, concrete, cement, and wood. For commercial buildings, optimal choices include steel, concrete, or cement. For residential buildings, professional roofing contractors will likely suggest plywood or tongue and groove systems. Ultimately, when a professional roofer is contracted to perform the work, they will suggest a limited range of options depending on the needs and requirements of the individual roof. This limited range is predicated based upon how much weight is resting on the roofing deck.
Fixing Roof to Decking
Once a roof deck has been selected and primed for installation, a roofer can then commence the next part of the roofing job, which is affixing roofing material to the roofing deck. In all scenarios, it is important to contact a roofer from a trust professional roofing company. This ensures that quality techniques and materials are utilized for all your roofing services. Depending upon the material selected for the roof installation, the roofer can then use industry grade techniques. For asphalt shingles, this process invariably includes a lot of measuring and chalk lines to ensure that all the shingles are laid down evenly in a row. Next, (once again using proper priming methods) the roofer may nail the drip edge in place using 1 ¼ -inch galvanized roofing nails and a hammer.
What Type of Plywood is Used for Roofing?
For many circumstances, construction experts love plywood for its enduring qualities, such as water resistance, structural stability, and low cost. Depending on the jurisdiction that you live in, plywood should be an acceptable choice for your roof deck installation. Depending on the state you live in, the modern standard for 24-inch rafter spacing is 15/32 inch. Because of the advances in lumber technology, 15/32 inch has become the norm versus the tradition ½ inch CDX (construction grade material intended for exterior use) plywood.
How Thick Should Roof Decking Be?
For roof rafters spaced 20 or more inches apart, ½ or ⅝ inch plywood is recommended. For the most popular rafter spacing, at 24 inches, 5/8th plywood is recommended. This is because this thickness of the roof deck will support roof loads for most roof situations and is considered to be the gold standard for most roof applications.
How Do I Know if My Roof Decking is Bad?
To begin with, there are various different structures that comprise a roof. The roof decking is defined as the structural component of the roof. Most roofing jobs include a minimum of three sheets of plywood that are part of the backbone of the roof. The roof underlayment is the protective layer keeping your home air ventilated and moisture resistant. The soffit is the underside of the eaves, and the roof covering is generally, popularly, shingles. The roof decking may be in a deteriorated state if homeowners witness the following: shingle curling and buckling, shingle granular wear, holes, mold or mildew in the attic, and missing shingles. If any of these signs or found on the roof, it’s time to call an expert to assess the overall roof damage.
How Much Does It Cost to Replace Roof Decking?
It is important to factor in roof deck costs when experiencing significant roof damage. Typically, for 300 square feet of roof decking, the cost could be $800-2,800 to install, depending on the chosen material. While it may seem relevant to focus time and attention to only the parts of the roof that are experiencing the most significant types of disrepair, in truth, for all installation jobs less than 100 square feet, there will be a potential up charge of 10-15%. Thus, it is important for when a problem arises, to get the entire roof estimate, and then handle the expense with that objective. It is of immense importance that homeowners choose the correct asphalt singles for their roof installation. Ask your local, trusted roofing contractor about what options are available in the roofing shingle of your choice.
Roof Decking with Insulation
Roof insulation is inevitably an important process attached to roof decking procedures. Insulation provides increased home energy efficiency throughout the year and provides an additional buffer from the weather elements that can affect a homeowner’s roof. Indoor air quality testing is important for homeowners experiencing allergies or congestion. Whenever embarking upon any home construction project, conduct an indoor air quality test to ensure that homeowners are breathing clean air.
Roof Decking vs Sheathing
Roof decking is also known by its other name, roof sheathing. Decking, or sheathing, is usually made up of plywood, wood boards, plants, or OSB that is graded for exterior use. When these roofing materials are painted with waterproofing coats, they can better handle rainfall during roof construction. The sheathing of the roof helps to keep the roof trusses or rafters properly spaced while maintaining the structure of the roof.
Roof Decking Bowing
If your roof decking has seen better days, you’re not alone. Many experienced roofing contractors can give you an honest opinion to ascertain whether or not your roof decking is in need of repair. Consult the following list to determine, on your own, whether or not you require these services.
- Bowing roof. If the structure of the roof is bowing or sagging, it often means there is a prevailing structural issue. There could be a problem with the decking, the attic, or the foundation, depending on the condition of the home.
- Holes. Water pervades even the tiniest holes in roofing structures, leading to water damage for the roof sheathing. Consult a trusted roofing contractor to remedy this situation.
- Curling and missing shingles. In general, missing shingles or shingles in various states of disrepair are a bad sign for the overall roof. This means that the underlayment is now exposed, and vulnerable to the weather.
