Life cycle of concrete roof tiles.

Scheme of the life cycle system boundaries of a concrete roof tile. The life expectancy of a concrete tile roof is 35 to 50 years. Similar to clay roofs the life expectancy of roof tiles made from concrete should be a minimum of 60 years. Manufacturers typically guarantee the tiles for 30 years and suggest that 60 years is a reasonable service life.

Clay and concrete roof tiles have a long history and a good track record. Concrete tile roofs have experienced 100 year lives in europe. Although the tile is rated by manufacturers as a having a 50 year life or more it is primarily a protective covering for the asphalt based roofing layer below it typically 30 pound felt or mineral surface roll roofing secured to the roof sheathing and down lapped. 2015 life cycle costs of metal roof concrete tile roof and the intelligent cooling roof.

The underlay will have a shorter lifespan which typically lasts for a 40 year period. Compared to unsightly weather beaten asphalt shingles and their replacement costs concrete roof tiles offer an affordable and economical alternative especially when considering their life cycle cost.

There are a number of factors that could contribute to the lifespan of concrete roof tiles. The material and energy inputs to the life cycle inventory of concrete roofing tiles are available in table a 2 of the appendix a. Typically roof tiles are expected to last for around 60 years as the production process is very similar across manufacturers and despite differences in the sand or coatings used most tiles would have a comparable 60 year lifespan. A coating agent is applied on the tiles as a protection layer.
