What is the typical installation requirement for roofing underlayment?

The typical installation requirement for roofing underlayment is based on manufacturer recommendations. This is crucial because different types of roofing materials and systems may have specific requirements for underlayment that ensure optimal performance, durability, and compliance with local building codes. Manufacturers conduct extensive testing and research to determine the appropriate underlayment for their products, which may vary depending on the climate, type of roofing, and specific installation situations.

Using underlayment according to the manufacturer's guidelines helps in mitigating risks such as water infiltration, ice damming, and other moisture-related issues. Additionally, following these recommendations can also safeguard warranties that the manufacturer provides on their roofing products, as failing to adhere to them could potentially void such warranties. This practice underscores the importance of aligning installation methods with expert advice in order to achieve the best outcomes for roofing projects.
