Your roof’s structure consists of trusses and joints with empty gaps in between these components. It has a flat surface that’s attached to the frame, which is called the roof decking. It serves as an additional layer of protection should your shingles fail. They’re also secured with weatherproof materials, such as the underlayment and shingles to protect it from the elements. But what is roof decking?
FUNCTION OF ROOF DECKING
While asphalt shingles may look light on the surface, they’re actually hefty at 2.5 pounds a shingle. Underneath the shingles are other materials like felt or tar paper. With the weight that it packs, the roof decking acts as a support system to keep all these layers intact. It helps distribute the weight equally through your home’s structure to withstand external forces, such as debris and harsh weather.
In fact, roof replacement contractors spray flame retardant on the decking to protect it against flames. However, you should consult your contractor before doing so because it may affect your roof decking’s performance.
PROTECTION FROM MOISTURE
Moisture is one of the biggest problems that affect every part of your roofing system. One common spot where moisture builds up is in your attic, which can affect your sheathing. As moisture builds up, the hot air can encourage mold growth in your roof decking that can spread throughout your entire roofing system. Be sure to have your roof inspected thoroughly to spot these issues and to find ways to properly ventilate your roof to prevent this issue from happening.
WHEN TO REPLACE YOUR DECKING
Some homeowners think it’s necessary to replace their decks during a roof replacement, but this isn’t entirely the case. However, you need to have your sheathing inspected to ensure that it’s in good condition before your roof is replaced.
