Which option is not a typical ice protection method for asphalt shingle roofs?

• A. A membrane extending from the eave to inside the exterior wall
• B. One layer of 90 pound hot mopped mineral surfaced membrane
• C. Ice shield at eaves
• D. Self-adhering underlayment across the roof deck

Answer: (B)

The correct option highlights a method that is not typically associated with ice protection techniques for asphalt shingle roofs. Ice protection methods are crucial in preventing ice dams and ensuring that water drains off the roof effectively. The other methods listed, such as having a membrane extending from the eave to inside the exterior wall, the application of an ice shield at the eaves, and the use of self-adhering underlayment across the roof deck, are all effective ways to manage ice buildup and protect the roof from potential water damage caused by melting ice. In contrast, a single layer of 90-pound hot-mopped mineral surfaced membrane is primarily used as a waterproofing method for flat or low-slope roofs rather than specifically as an ice protection system for asphalt shingles. While it may provide some level of protection, it does not directly address the common issues related to ice dam formation on sloped roofs with asphalt shingles.
