What additional protection should be provided in valleys besides normal felt or tar paper?

• A. One layer of 36-inch roofing felt
• B. One layer of 36-inch roll roofing
• C. One layer of 36-inch ice and water shield
• D. All of the above

Answer: (D)

In roofing, valleys are critical areas where water can accumulate and flow, making them particularly susceptible to leaks if not properly protected. In addition to the standard felt or tar paper that is usually placed under roofing materials, additional protection is recommended to ensure a watertight seal. Using an ice and water shield, especially in valleys, is essential because it is designed to provide a superior level of waterproofing. Ice and water shield adheres well to the roof deck surface and forms a barrier that prevents water infiltration, particularly in colder climates where ice dams can form. This material remains flexible even in low temperatures, helping it conform to the roofing surface and effectively sealing potential entry points. In some cases, the additional use of 36-inch roll roofing or even having an extra layer of standard roofing felt can enhance protection by providing redundancy in water barrier systems. Roll roofing can cover larger areas efficiently and provides a secondary layer of waterproofing, while additional roofing felt can further assist in managing moisture. Therefore, selecting a comprehensive solution that includes multiple layers or types of protection, such as ice and water shield along with other options, ensures that valleys are fortified against the damaging effects of water intrusion. This multifaceted approach acknowledges that valleys are prone to increased water flow and, consequently
