Haag 4/09 and 12/1 shingle gauges

Haag 4/09 and 12/1 shingle gauges

The 409 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 409 Shingle gauge by testing asphalt-based composition shinglesIn the spring of 2012, Haag Engineering released a redesigned Shingle gauge Why was the 112 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 US 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 Whats 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 112 Shingle gauge measures the thickness of 3-Tab shingles, and based on analyses made by Haag, correlates that thickness to a warranty rangeWhy is the 409 Shingle gauge still available Since Haags 409 Shingle gauge remains accurate on roofs installed before January 2011Is there any type of shingle the Shingle gauge cannot measure Yes Any type of shingle (3-Tab or Laminated) made with modified asphalt ( impact resistant) does not conform to the 409 or the 112 Shingle gauge
