Based on analyses made by Haag Engineering, the thickness correlates to a warranty level Designed with the strictest analytical tolerances possible Scales for both 3-Tab Organic and Laminated shingle varieties Total cost including shipping less than purchaing from Haag directly A great tool - important for determining what a comparable replacement shingle might be Includes a ruler on one side The 4/09 Shingle Gaugeâ„¢ 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 Gaugeâ„¢ 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 Gaugeâ„¢ by testing asphalt-based composition shingles. Modified asphalt shingles (commonly called "impact re
