Davis Roofing: Article About Concrete Roof Tiles
Concrete is one of the most durable options for the roofs of today's homes. Impervious to mold and rot, concrete tiling will last the home owner for many years. In fact, some of the first concrete tiles, made in Germany during the 19th century, are still on roofs today.
Concrete roofing tiles are usually made of Portland cement, fly ash, blended hydraulic cements and aggregate material. The actual materials will vary depending on the manufacturer, although the tiles themselves tend to resemble one another in design.
There are three main types of concrete tiling. These include flat profile, low profile and high profile. Flat profile tiling features no curves when viewed from its butt. Low profile concrete roofing has small curves with a rise to width ratio of 1:5 or less. High profile tile has larger curves than low profile tiling with a rise to width ration of 1:5 or more. Home owners should contact a Davis roofing contractor for more information regarding the most suitable roofing style for their homes.
Concrete tiling is available in various color and surface texture combinations. Profiled tiles resemble terra cotta tiling in appearance.

When selecting concrete tiling for a roof, it is important to select standard weight tile over lightweight. Lightweight concrete tiles are susceptible to breakage from hail and human weight. They also tend to be more expensive.
Concrete roofs have a life expectancy of approximately 50 years, a 25 year advantage over asphalt shingles. Keep in mind that the underlying system will require a replacement after 30 to 40 years. If the underlying system is faulty or inferior, the replacement will need to be performed much sooner.
Because concrete tile roofs are especially prone to moisture penetration from wind driven snow or rain, it is vital to ensure that the underlying systems and the flashing are properly installed to prevent moisture intrusion. A concrete tile roof consists of a single "ply," while asphalt shingle and wood shake roofs are two and three ply, respectively. Birds, small animals and insects are known to weasel their way beneath concrete tiling and take up residence in a poorly installed concrete tile roof.
Concrete tiling is beneficial for those living in areas prone to heavy snow fall because it permits the snow to slide more easily off the roof than other types of roofing. It can also be installed in temperature extremes ranging from sub freezing to over 120 degrees.
