If you are like most people, you’re probably not familiar with all the important components that go into an effective residential roofing system. Sure, you might know what shingles and gutters are. You might even be able to point out the flashing on your roof. But what about what’s underneath? In today’s post, we explain what roofing underlayment is and why it is such an integral part of your roof.
The Importance of Roofing Underlayment
The underlayment of your roof is a water-resistant or sometimes waterproof barrier that is installed underneath your other roofing materials like your asphalt shingles or tiles. Needless to say, its main function is to serve as a layer of protection from the harshness of the weather, particularly the rain. To put it simply, it is the final obstacle that water must overcome after it has gone through everything else to be able to get into your interior.
The Three Types of Roofing Underlayment
Asphalt-Saturated. Asphalt-saturated felt used to be the most commonly used underlayment material until fairly recently. Now, synthetic materials are preferred by most roofing contractors. Despite this, it is still popular due to its ready availability and affordability.
Non-Bitumen Synthetic. Non-bitumen synthetic has replaced asphalt-saturated underlayment as the underlayment of choice. It offers better resistance and is designed for full application on the entire roof.
Rubberized Asphalt. This is what your roofing contractor will recommend if you want a premium underlayment that offers the most protection. Unlike the first two underlayments mentioned above, rubberized asphalt is completely waterproof thanks to its special backing that creates a seal between it and the roof deck.
