Reference Books & Tools
Created by Haag engineers, known throughout the industry not only as scientifically rigorous practitioners but also as outstanding communicators, Haag’s reference books and tools serve as handy resources in the field. Our line of reference books includes the Composition, Tile, and Wood Field Guides, as well as our new Built-Up Roofing Field Guide. Haag’s tools include our popular Shingle Gauges, which estimate a shingle’s warranty, and our Pitch Gauge and Inclinometer, which estimate a roof’s pitch.
