Roof Deck Demystifying the Obscure and Underappreciated

 

What Is It for?

The functionality of the roof deck could be fourfold. Bearing the weight of roofing components, especially asphalt shingles, withstanding the impact of wind-blown debris like tree branches, delaying the spread of flames in case of a fire, and stopping leaks are its main duties. Irrespective of material or configuration, its unenviable job description remains the same.

What Can Compromise Its Structural Integrity?

Also known as roof sheathing, the deck is made of either plywood or wood-based oriented strand board. Because of its nature, water is its nemesis.

It is impossible to eliminate every source of moisture to keep roof sheathing dry and solid. But what you can do is cover it with a suitable underlayment solution to intercept wind-driven rain that manages to seep into the shingles. Also, boost your attic insulation and ventilation to expel extreme heat and moisture-ridden warm air adequately.

Should It Be Replaced When Buying a New Roof?

In roof replacement, the decking does not have to be broken. If the material has no signs of decay and does not sag whatsoever, it could stay untouched.

However, you may need a new one if you are switching to a heavier roof covering. The requirements of gutter installation might also trigger some structural modification to your property. And the roof deck could be affected one way or another.
