What is a hail damage test square?
A hail test square is a 10×10 foot sample section of roof marked with chalk to count impacts — 8 or more indicative-damage strikes per square typically warrants a full roof replacement claim. Adjusters use the test square method per Haag Engineering and NRCA inspection guidelines.
