The roof is undoubtedly the most vital part of any building. It is a structure’s first line of defense against the elements. However, there’s more to a roof than meets the eye. Underneath the shingles or tiles, there’s a critical component that plays a significant role in safeguarding your home or business premises. This component is the roof underlayment.
What is Roof Underlayment?
Roof underlayment is a water-resistant or waterproof barrier installed directly onto the roof deck. It is applied under all other roofing materials as an added layer of protection from severe weather. While it is often overlooked during the roof installation process, its contribution to the longevity and health of the roof cannot be underestimated.
The Key Roles of Roof Underlayment
The roof underlayment serves several essential functions that enhance the overall effectiveness of the roof. These functions include:
- Protection against Resonance and Wind-driven Rain: High winds can drive rain under your roof’s exterior covering, potentially causing damage to the roof deck. Roof underlayment acts as a barrier, protecting the roof deck from these elements.
- Backup Weather Barrier: In the event that the outer roofing fails, the underlayment serves as a secondary weather barrier, minimizing potential water damage.
- Improved Fire Resistance: Some types of roof underlayment provide a fire-resistant layer that can help prevent the spread of fire to the roof.
Types of Roof Underlayment
There are three main types of roof underlayment:
- Asphalt-saturated Felt: This is the traditional type of underlayment, often referred to as “felt paper”. It provides a reasonable degree of water resistance.
- Rubberized Asphalt: This type of underlayment contains higher amounts of asphalt and rubber polymers, making it waterproof. It is often self-adhering and provides excellent protection against ice dams and wind-driven rain.
- Non-bitumen Synthetic Underlayment: Synthetic underlayment is usually made from polypropylene or polyethylene. It’s favored for its lightweight, high tear resistance, and water resistance.
The Right Underlayment for Your Roof
The choice of underlayment depends on several factors including the roofing material, the pitch of the roof, and the local climate. For instance, in areas prone to high winds and heavy rain, a waterproof underlayment would be the best choice. On the other hand, for roofs with a steep pitch, a water-resistant underlayment might suffice.
