The Growing Problems with Concrete Roofing Materials

 

 
 

While Concrete Roofing Tiles have become a viable alternative for homeowners, they do pose many concerns. It is important for homeowners to understand that concrete roofing materials are very climate specific, in hot climates they perform well, however in other climates they pose concern.

Concrete roof tiles are available in three basic profiles: mission S-tiles (or "Spanish S"), villa tiles (low-profile tiles with a double-S shape), and flat tiles, which are often designed to look like wood shakes or slate.

Weight is a Serious Concern

Standard-weight concrete roof tiles generally weigh between 9.5 to 12 pounds per square foot. In comparison, CeDUR is just a staggering 1.7 pounds per square! (The roofing industry considers 1 square as a 10’ ft x 10 ft area on your roof).

For homes where weight is a concern, many concrete tile manufacturers offer lightweight options, however those options still weigh 5.5 - 7.5 pounds per square. Even roofing products that are labeled as “lightweight concrete tiles” by the manufacturers are heavy, because concrete by design is an extremely dense material.

The Combination of Moisture and Concrete Is Troublesome

Concrete roof tiles are available in three basic profiles: mission S-tiles (or "Spanish S"), villa tiles (low-profile tiles with a double-S shape), and flat tiles, which are often designed to look like wood shakes or slates.

For houses where weight is a concern, many tile manufacturers offer lightweight roof tiles weighing 5 1/2 to 7 pounds per square foot.

Many people consider asphalt shingles to be heavy, however in comparison asphalt shingles generally weigh only 3-4 pounds per square.

Standard-weight concrete roof tiles generally weigh between 9 1/2 and 12 pounds per square foot — significantly more than asphalt shingles, which weigh only 2 1/2 to 4 pounds per square foot. For houses where weight is a concern, many tile manufacturers offer lightweight roof tiles weighing 5 1/2 to 7 pounds per square foot. These tiles are made with a lightweight aggregate, like expanded shale, instead of sand.

Even roofing products that are labeled as “lightweight concrete tiles” are most likely because concrete by design is an extremely dense material.

Breakability and Weathering Issues

If you live in a hail prone environment your concrete roof may experience breakbility issues.
