Concrete Roof Tile Products Certified for Hail Impact Protection Resulting in Insurance Rate Reductions for Homeowners

IRVINE, CA--(Marketwire - April 23, 2009) - Hail storms continue to ravage the hail belt and wreak havoc on non-durable roofs. In an average year, hail causes more than $1.6 billion worth of damage to residential roofs in the United States, making it one of the most costly natural disasters. There is a concrete solution, however. The insurance industry's recognition of the recent Architectural Testing certification of concrete roof tile products will have positive implications for homeowners and builders in U.S. hail regions providing further confidence in the product's known durability and performance in all climate regions.

An industry-wide test for concrete roof tile was conducted using the Factory Mutual (FM) 4473 testing methodology. This test requires that tile is impacted in 3 different locations by ice balls ranging from 1 1/4" to 2" in size. The ice balls are shot at terminal velocity and each tile tested has to withstand 6 hits each. To successfully complete the test, the tile has to withstand the hits without breaking the tile (or showing any visible cracks), using the different sized ice balls for each test.

Class/Measurement is as follows:
Class 1: 1 1/4" ice balls
Class 2: 1 1/2" ice balls
Class 3: 1 3/4" ice balls
Class 4: 2" ice balls

The test results showed that MonierLifetile's standard weight flat tiles achieved the highest rating of Class 4 and all other products attained a Class 3 rating. The Architectural Testing certification backs the Factory Mutual testing methodology and lists the certified products on their website at State Farm Insurance also lists the approved products' certification on their web site at

Homeowners can now choose the certified MonierLifetile products and reap the benefits of utilizing a product that protects their property from hail damage. Both existing and new homeowners with a MonierLifetile roof can contact their insurance provider with the completed form signed by their contractor and request a rate reduction.
