Expert Verdict Reviewed by the SuperArbor Pro Desk

Weather blocks close the open gap at hips and ridges before ridge tile goes on, helping block wind-driven rain and debris. Run the block continuously and butt or lap sections per the manufacturer’s instructions. Confirm the block width suits your tile profile’s hip/ridge opening; 13.5 in. covers most standard high-profile applications.

Install hip and ridge weatherblocking while maintaining proper fall protection and follow the tile manufacturer’s installation instructions and local code.
