Haag Engineering Announces 2012 Version of its Shingle Gauge™

Cannot Create Laminated Section of the Gauge. New “Lifetime” Warranties on Laminated Shingles Prompts Reevaluation.

“The link between thickness and warranties had been consistent for nearly two decades, but is now limited for three-tab shingles and nonexistent for laminated shingles,” said Scott Morrison, P.E., Research/Testing Coordinator for Haag Engineering.

Haag Engineering will release a redesigned Shingle Gauge™ in early 2012. The Haag Shingle Gauge – the only tool of its kind on the market today – is used nationwide by roofing inspectors and insurance adjusters to estimate current or replacement warranties of shingles. Due to warranty changes within the industry, the 2012 Gauge will not include a Laminated shingle section.

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 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. This further complicates matters.

“The link between thickness and warranties had been consistent for nearly two decades, but is now limited for three-tab shingles and nonexistent for laminated shingles,” said Scott Morrison, P.E., Research/Testing Coordinator for Haag Engineering. “Without a strong correlation between thickness and warranty for laminated shingles, we can’t produce a reliable and accurate measurement. So, to help avoid any confusion we will not continue the “laminated” section of our Shingle Gauge.”

Haag Engineering continually monitors revisions and additions to shingle manufacturer warranties to ensure the accuracy of its Shingle Gauge. Because these warranties change frequently, Haag recalibrates the Shingle Gauge every 3-4 years, or as trends demand. Originally introduced in 1993, re-designed in 2004, and updated in 2006 and 2009, the Haag Shingle Gauge gives inspectors and adjusters an accurate, one-of-a-kind warranty estimate tool. Haag’s “01/12” 3-Tab Shingle Gauge will be available in spring 2012. Please visit http://www.haageducation.com/shinglegauge for the latest information.

Haag’s current version of the Shingle Gauge “4/09” remains accurate on roofs installed in January 2011 or before. Haag will continue to sell its remaining stock of these gauges.
