What is a common brand of synthetic roofing underlayment?

A common brand of synthetic roofing underlayment includes products such as Tyvek and Ice and Water Shield. These materials are designed to provide superior moisture protection compared to traditional underlayment materials. Tyvek, for instance, is a breathable barrier that allows moisture vapor to escape while preventing water from entering, which helps in reducing the risks of mold and mildew buildup under roofing systems.

Ice and Water Shield specifically is engineered to adhere to the substrate, providing a waterproof barrier in vulnerable areas, especially in climates prone to ice dams. This means that the correct answer is correct because these synthetic underlayments offer enhanced performance and reliability in protecting homes compared to non-synthetic options.

In contrast, tar paper and asphalt felt are traditional underlayment materials that are typically less effective in terms of moisture management and durability. Wood fiber board is not generally used as roofing underlayment, as it serves different purposes, like insulation or as a substrate for other roofing materials. Thus, the choice of Tyvek or Ice and Water Shield reflects the modern advancements in roofing technology aimed at improving the longevity and performance of roofing systems.
