Roofing Underlayment and Its Importance

If you’re having a new roof installed, then you’ve probably heard your contractor mention the roofing underlayment. It refers to the thin, waterproofing material installed between the roof deck and the asphalt shingles. The underlayment is an integral part of the roofing system because it contributes to its weather performance.

Deschutes Roofing & Insulation, the premier roofing and seamless gutter company in the area, expounds on the importance Underlayment here.

It Prevents Leaks. The asphalt shingles take the brunt of weather damage, and they’re usually enough protection against possible water infiltration. But if rainwater somehow manages to get past the shingles, the roofing underlayment stops it from getting any further. This is the reason the underlayment is also termed ‘water barrier,’ because that’s exactly what it does.

It Makes Your Roof Last Longer. Because the underlayment helps eliminate the potential for leaks, this means the roof deck and structure won’t be exposed to water or moisture. This, in turn, prevents the formation of mold and rot, which can cause severe structural damage to your roofing system when left unchecked.

Types of Roofing Underlayment

The underlayment comes in three different options, each providing sufficient, leak-free protection for your roofing system. The quality may vary, however, and you might need a reliable roofing repairs company like Deschutes Roofing & Insulation to help you decide. Here are your available options:

Non-Bitumen Synthetic. A proven option, a non-bitumen synthetic underlayment is flexible and extremely weather-resistant. It’s also a cost-effective choice because it is designed for full application on the entire roofing system.

Asphalt-Saturated. Even if non-bitumen synthetic has become the go-to underlayment type for residential roofing, asphalt-saturated remains a solid option because of its waterproofing action and availability.

Rubberized Asphalt. Considered a premium material, rubberized asphalt underlayment can offer most of the exceptional advantages of its counterparts. It comes with a higher percentage of asphalt and rubber polymer, which makes this type completely waterproof.

We got in touch with Carlos on a Saturday desperate for help with our ice dams, as we had water actively running into the house. He got a crew together for us the next day.
