Roofing Material Failure
Abstract
Kirk and Fred discuss the recent failure of his roofing tiles and the testing that should have been done for roofing materials that will be used in all geographical locations.
Key Points
Join Kirk and Fred as they discuss how his roofing failed and the manufacturer going out of business
Topics include:
- The tiles on Fred’s roof after two years became so brittle that raccoons running across the tiles would break them.
- How many years should a building be built for, as many houses have lasted for decades or a century? The southwestern native Americans have adobe multilevel buildings that are maybe hundreds of years old, and they are made of mud and straw.
- Pressed fiberboard is a standard material used in house siding and composite floors. Fred discusses an issue with siding failures on a previous house and getting a warranty replacement, and Kirk discusses the delamination of his composite flooring.
- Some building materials manufacturers do simple stress testing on newly constructed windows, door seals, and other components, and do not consider that the materials and assemblies’ fatigue damage will accumulate, causing failure of the same tests over time.
- Find out at the end of the podcast, the very reliable material Fred will be replacing his roof with, a slip-and-slide for raccoons!

Please click on this link to access a relatively new analysis of traditional reliability prediction methods article from the US ARMY and CALCE titled “Reliability Prediction – Continued Reliance on a Misleading Approach”. It is in the public domain, so please feel free to distribute it. Attempting to predict reliability is a misleading and costly approach to use for developing a reliable system.
