Summary

The modification facilitates changing the term replaced to reroofed in this paragraph. The existing language has been interpreted to prohibit recovering more than 25% of a roof or roof section which is not the intent of this section.

The modification eliminates the prescriptive language in this volume and section and instead directs the user to the proper underlayment sections of the code where additional options are available. This section will then indicate when a secondary water barrier is required.

Changes the test methods used to establish resistance to uplift pressure for tile underlayments to methods described in the code. The underlayment is part of the load path for most tile roof systems and product approval should demonstrate an expected resistance to negative pressure.
