When it comes to planning a roof replacement project, a large part of it usually involves browsing through different shingle colors, textures and other additional features. While that’s understandable, you should be aware of the other components of the asphalt shingle roofing system you’re going to install. After all, they also play a major role in ensuring your home’s protection against the weather.
The underlayment, for instance, doesn’t often get the same attention as the shingle and other visible roof elements. However, it also plays a crucial role in keeping your roof intact by stopping moisture from getting into the attic and your home interiors.
How Roofing Underlayment Works
The underlayment is a roofing material sandwiched between the shingles and roof deck. It acts as a protective layer that prevents water from entering the structure and causing mold growth and rot on the wooden components. It also acts as a thermal barrier that helps keep out the outdoor heat during the summer months and retains the indoor temperatures during the winter season.
Common Underlayment Options
Just like your shingles and the rest of your roofing system, the underlayment needs to be replaced after several years depending on its condition. They’re also available in several types for all kinds of residential roofing systems. Below are a few of the most common ones available on the market:
- Synthetic – Although non-bitumen synthetics tend to cost more than the traditional underlayment types, they’re still one of the most popular types you can find. With this material, you get a completely waterproof and insulated barrier between your shingles and roof deck. While it resists water and ice penetration, it’s also breathable as it allows humidity to escape!
- Rubberized asphalt – This is another popular material that offers premium roofing protection and leak prevention even in extreme temperatures. It is primarily made of rubber polymers and asphalt which resemble a rubber-like material. They’re also self-adhering because they come with an adhesive backing that sticks directly to the deck.
- Felt – This classic type of underlayment is mostly made of organic felt that’s saturated in asphalt. Depending on the manufacturer, it might also contain some fiberglass reinforcement for increased longevity and strength. Asphalt-saturated felt makes the underlayment water-resistant, but only for several years. It will eventually wear down and become vulnerable to the elements.
