What is the difference between underlayment and secondary water barrier?

Underlayment is a layer of material installed between the roof deck and the roofing material (shingles, tiles, etc.) to provide an additional layer of protection against moisture and weather. A secondary water barrier is a specific type of underlayment designed to provide extra protection against water intrusion, particularly in areas prone to severe weather, ensuring that even if the primary roofing material is compromised, the barrier helps prevent water from reaching the roof deck.

What are the requirements for roofing underlayment?

Roofing underlayment must be durable, water-resistant, and capable of withstanding high temperatures. It should meet industry standards for fire resistance, tear strength, and UV resistance. The specific requirements can vary depending on the local building codes and the type of roofing material used.

How much weight can underlayment hold?

Roofing underlayment is not designed to support weight like structural components. It is primarily a protective layer against moisture. While it can handle some weight from workers during installation or repair, its main function is not load-bearing. The weight capacity will vary depending on the type and brand of the underlayment, but it is generally not intended to support significant weight.
