Sheathing is the base layer of your roofing system that supports the shingles or tiles on top, and is usually made of either plywood or oriented strand board (OSB). The material you pick will change everything from your home’s insulation to its resistance to weather, so choosing the right type is crucial for long-lasting roof performance.
In Ohio, Tennessee, South Carolina, and Georgia, the weather can range from moderate to extreme; from frigid in winter to downright swampy during the summer. Depending on which state you live in, the ideal sheathing type isn’t always the same. From cold Cleveland winters to muggy Georgia summers, read this expert guide from Division 1 Roofing to find out how to find the right sheathing materials for all four seasons.
Roof Sheathing for Different Climates
As we mentioned earlier, there are two main types of roof sheathing material: plywood and strand board. Choosing the right type will give you protection for your home that lasts the test of time and requires fewer roof repairs. Here’s a quick breakdown of what works best where:
Hot and Humid Climates
If you live in a hot, humid area, like parts of Georgia or South Carolina, you’ll want a roof sheathing that resists moisture and heat. Exterior-grade plywood (CDX) sheathing, with its layers of wood veneer, provides excellent stability and holds up well against the effects of humidity. Additionally, radiant barrier sheathing can help reflect heat, reducing the load on your air conditioning system and improving your home’s energy efficiency.
Cold and Wet Climates
In regions that experience colder, wetter seasons, like parts of Ohio and Tennessee, it’s essential to use sheathing that can handle expansion and contraction from temperature fluctuations. OSB is often a preferred choice here due to its strong resistance to warping. Opting for water-resistant treated OSB sheathing can also provide additional protection against mold and mildew, which can form when moisture seeps into the roof structure.
