Which type of roofing material is most affected by cold temperatures requiring solid sheathing?

Wood shingles are significantly affected by cold temperatures due to their natural properties. When temperatures drop, wood can contract, which may lead to gaps forming between shingles if they are not properly secured or if the sheathing beneath them is inadequate. Solid sheathing provides a stable and supportive base for the wood shingles, ensuring that they maintain their integrity and alignment despite temperature fluctuations. This is crucial because wood shingles rely on their ability to expand and contract without compromising the roof's effectiveness.

The other roofing materials, while they may also be impacted by temperature changes, do not require the same level of support from solid sheathing. Metal roofing is generally more resilient to temperature changes due to its properties, asphalt shingles can handle a variety of conditions without extensive support, and tile roofing often has different installation requirements that make it less susceptible to issues caused by cold temperatures compared to wood shingles.
