WeatherLock® Specialty Tile & Metal underlayment provides the weatherproofing protection your home needs to help prevent leaks. Unlike felt underlayment, WeatherLock® Specialty Tile & Metal underlayment will not melt, tear or degrade when exposed to moisture, severe heat or cold weather.

Its high puncture and tear-resistant surface provide peak performance while the single-layer polyester walking surface provides a slip-resistant work area for safe installation. It is approved for use under all metal roof systems, including copper and zinc, and an excellent surface for foam-adhered and mechanically fastened roof tile applications. It's an essential part of a complete roofing system.
