What Is Roof Underlayment on an Orangevale Home?
Roof underlayment on an Orangevale home is the layer that covers the wood deck under the shingles. The Asphalt Roofing Manufacturers Association says shingles should not be installed directly on a wood deck. It says the deck should first be covered by a roofing underlayment. Porter Roofing offers free estimates for Orangevale roofs.
The association lists several jobs for underlayment. It acts as a secondary layer of protection that shields the deck from wind-driven rain. It helps keep the deck dry until shingles are applied. It also protects shingles from resins that may come from wood-based sheathing.
The Main Types of Roof Underlayment
The association's page describes several kinds of underlayment. The table summarizes three of them. Ask your roofer which kind is planned for your roof.
| Type | Summary of the page |
|---|---|
| Asphalt-saturated felt | Widely used as asphalt shingle underlayment. |
| Synthetic | Lighter than felt and covers more area per roll. |
| Self-adhering | Acts as a vapor retarder. Ventilation matters more when it covers the entire roof deck. |
To read all of it, see this roofing association's underlayment page. It says to consult local building codes and the shingle maker's requirements when choosing a product. Your roofer can go through it with you.
Self-Adhering Underlayment and Ventilation in Orangevale
One type comes with a ventilation note attached. The association says self-adhering underlayments act as vapor retarders. It says ventilation becomes increasingly important when they are used over the entire roof deck. Ask your roofer how an Orangevale roof will be ventilated if this type is chosen.
Synthetic products are lighter than saturated felts. They also cover more area per roll, according to the association. Which product goes on a roof is a choice to make with your roofer. Local code and the shingle maker's requirements guide that choice.
