Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tile roofs depend on a sound underlayment as the true weather barrier, so order enough rolls for full coverage plus laps. White surfacing can make working conditions more comfortable during the dry-in. Verify deck condition and lap requirements before starting the install, since tile systems rely heavily on underlayment quality.
Work on sloped roofs with proper fall protection and follow local building code and manufacturer installation instructions.
Order Westlake Royal TileSeal Underlayment by the roll to dry in your tile roof project.
