4/09 Shingle Gauge

The 4/09 Shingle Gauge™ measures the thickness of a shingle, and based on analyses made by Haag, correlates that thickness to a warranty level. Knowing a warranty level can be important in determining what a comparable replacement shingle might be. While the Shingle Gauge™ was designed with the strictest analytical tolerances possible, we still consider it an estimating tool due to a small number of shingles which do not conform to the gauge. Haag created the 4/09 Shingle Gauge™ by testing asphalt-based composition shingles. Modified asphalt shingles (commonly called "impact resistant") were not included in our testing and are not applicable to the 4/09 Shingle Gauge™.

In the spring of 2012, Haag Engineering released a redesigned Shingle Gauge™. Why was the 1/12 Shingle Gauge™ created, and why does it not include Laminated Shingles? In early 2011, most asphalt shingle manufacturers introduced "lifetime" limited warranties for their products. Haag responded by acquiring 76 models of these shingles from every U.S. manufacturer to measure shingle thicknesses and to compare against their warranties. The testing concluded laminated shingles could not be separated by thickness into warranty categories. The thicknesses of new "lifetime" warrantied shingles varied dramatically. What's more, many manufacturers limit "lifetime" warranties to residential installations and use a year designation for commercial-use installations. Without a strong relationship between warranty and thickness, we could not create an updated Gauge which includes Laminated Shingles.  Thus, the 1/12 Shingle Gauge™ measures the thickness of 3-Tab shingles, and based on analyses made by Haag, correlates that thickness to a warranty range.

Why is the "4/09" Shingle Gauge™ still available? Since Haag's "4/09" Shingle Gauge™ remains accurate on roofs installed before January 2011, we will continue to sell this version for the foreseeable future.

1/12 Shingle Gauge

The 1/12 Shingle Gauge™ measures the thickness of 3-Tab shingles, and based on analyses made by Haag, correlates that thickness to a warranty range. The 1/12 Shingle Gauge™ is an estimating tool which provides users with a warranty range for 3-Tab Shingles. There are a small number of outlying shingles which do not conform to the gauge.

Haag Engineering's most popular book, the Composition Roofs Damage Assessment Field Guide, focuses on assessment of manufacturing and installation issues, weathering anomalies, hail and wind damage, and mechanical damage. It features a comprehensive glossary. Large, detailed photos and informative captions make this guide a must-have for those involved with damage assessment of composition roofs.

Haag's Composition Roofs Damage Assessment Field Guide
 
  • More than 35 new photos and diagrams in our newest edition
  • New pages on shingle tabs which are not sealed (in both racking and straight-up patterns)
  • Hail damage thresholds to different roofing types as determined by Haag Research/Testing
  • A detailed explanation of wind uplift effects on  shingles
  • Roof diagraming info (to help you differentiate simulated damage from natural damage)
  • A step-by-step shingle insert repair pictoral
  • And more!

Keep this guide on your desk as part of your essential reference library, or carry it in the field to aid in explaining your findings to others. Just like the 1st Edition, Haag’s 2nd Edition Composition Field Guide is written by expert Haag Engineers to help you identify and differentiate common conditions found in field (from manufacturing, installation and weathering anomalies, to hail, wind and mechanical damage).  And, it’s designed to be an easy, durable, on-the-go reference featuring large, color photos with detailed explanatory captions.  

Pitch Gauge

Haag's Pitch Gauge is a simple plastic card that helps you quickly estimate a roof's pitch by viewing through the card & matching the slope lines to the slope of a roof. It is most accurate on gable roofs and at greater distances.
