Understanding Sub Roofing: A Comprehensive Guide: 1 Minute to Mastering the Basics of Sub Roofing

Sub roofing is essential for creating a robust roof structure that can withstand the elements while also safeguarding your ceilings and interiors from moisture damage. It is often overlooked, yet plays a critical role in the overall effectiveness of your roofing system.

Many homeowners might ask, what exactly is sub roofing? Sub roofing, also known as roof decking or sheathing, is the material placed on the roof rafters or trusses, serving as a base layer for your roofing material.

What is Sub Roofing?

Sub roofing serves as an underlayment that contributes to the insulation and protection of your home. It is typically made from plywood or oriented strand board (OSB). This layer not only provides structural integrity to the entire roofing system but also acts as a barrier against water infiltration and weather conditions.

Installing sub roofing is a crucial step when constructing or upgrading your roof. It helps in achieving a flat, even surface for the installation of your roofing materials, such as asphalt shingles or metal roofing.

Benefits of Sub Roofing

1. **Increased Durability**: The primary benefit of sub roofing is that it adds an extra layer of protection to your home. It reduces the risk of leaks and water damage by providing a solid barrier.

2. **Improved Insulation**: Sub roofing enhances your home's insulation, which can lead to better energy efficiency. This translates to lower heating and cooling costs.

Types of Sub Roofing Materials

There are various materials available for sub roofing, including plywood, OSB, and metal sheets. Each material has its own set of advantages, and your choice may depend on factors such as climate, roofing style, and budget.

3. **Plywood**: Offers strength and resistance to warping, making it a popular choice for sub roofing installations.

4. **Oriented Strand Board (OSB)**: Typically more affordable than plywood, OSB is made from compressed wood strands and is suitable for providing structural support.
