In areas where the average daily temperature in January is 25°F and below, what type of sheathing is required for wood shingles?

• A. Solid sheathing
• B. Vented sheathing
• C. Insulated sheathing
• D. None of the above

Answer: (A)

In regions where the average daily temperature in January is 25°F and below, solid sheathing is required for wood shingles to ensure adequate protection against cold weather. Solid sheathing provides a continuous, stable support base that minimizes the chances of air infiltration and moisture accumulation, which are critical concerns in colder climates. This construction detail helps maintain a barrier against the elements, ultimately promoting better performance of the roof assembly and reducing the risk of ice dams and water infiltration. Additionally, using solid sheathing enhances structural integrity and assists in even distribution of loads, which is particularly important in environments where snow accumulation can occur. Though vented sheathing and insulated sheathing might offer benefits in certain applications or climates, they are not the prescribed requirement in this specific scenario, thus reinforcing the necessity for solid sheathing to combat the challenges posed by lower temperatures.
