Roof decking represents the flat surface of the roof. Like the frames to which it is attached, roof decking has the primary job of supporting the weight of the actual covering that protects and beautifies the roof.
Also known as roof sheathing, the roof decking plays other roles too. It serves as your house’s last line of defense against the elements. Also, professional roof contractors will say that this component helps slow down the spread of flames in the event of a fire.
To further appreciate the function and importance of the roof decking, Shelter Construction Services shares some interesting facts below.
Oriented Strand Board (OSB) Decking Is Today’s Standard
Plywood used to have this distinction, but it could not rival the mechanical properties of OSB to retain its title. A kind of engineered wood, OSB produces rigid uniform boards with exceptional moisture resistance.
Decking Replacement Is Not Always Necessary
Generally, replacing structurally sound decking boards makes no sense. However, any asphalt-shingle, cedar-shake, slate and custom metal roofing professionals will argue that structural modification of the old roof sheathing could be in order when switching to heavier covering material.
Furthermore, the roof decking must be inspected thoroughly in order to assess its condition more accurately, which can’t be done without adequate access. If the attic does not allow proper evaluation, there is no way to size up the roof decking’s integrity until the covering components are torn off.
Rot Is No Laughing Matter
Moisture is the nemesis of the roof decking. Rotted boards should be addressed sooner rather than later, for these weakened pieces could make your roof more vulnerable to the weather and increase the cost and frequency of hail damage roof repair jobs.
