The roof protects your home and family from harsh elements outside. Shingles, gutters and downspouts are commonly seen by homeowners, but most are unaware of what’s beneath the surface. Roofing underlayment is one of the hidden yet integral parts of the whole roof system.
Roofing Underlayment
The underlayment is a water-resistant or waterproof barrier that is installed directly onto your roof deck, to where all other roofing materials are connected. It’s usually used as a necessary additional layer of protection from harsh weather conditions and consequential damage like roof leak.
Three Main Types of Roofing Underlayment
1. Asphalt-saturated felt was the most commonly utilized type until synthetic materials came into existence. A flexible base layer, it’s also water-resistant and affordable.
2.Non-bitumen synthetic underlayment is now the go-to type of most roofing experts. It’s an upgraded choice given that it’s both tear and water resistant, and also incredibly stable due to additional fiberglass. It’s also intended for the entire roof deck.
3. Rubberized asphalt is the most expensive underlayment. Containing a higher percentage of asphalt and polymers, it’s now a waterproof material.
The Importance of Roofing Underlayment
There are a range of reasons why roofing underlayment is a necessity for every household. The primary thing is it serves a moisture barrier. Although shingles reflect sun heat and withstand wind, they aren’t sealed at corners, making them vulnerable to being lifted off by strong winds.
Water-resistant underlayment provides protection for the surfaces of most roofs, but the waterproof underlayment type should be used on specific regions like eaves and valleys. It’s recommended for homeowners in places prone to high winds or ice damage.
