Benefits of using lightweight concrete roof tiles include strength that can hold up through extreme wind and storms and cost, which is much lower than that of slate or clay tiles. Concrete roof tiles also last longer than other materials if installed correctly and regularly maintained. Some companies also offer warranties on their roofs for as long as 50 years.
Specialty concrete tiles, such as the Eagle Platinum Tile by Eagle Roofing Products, have been proven to reduce the transfer of heat in and out of a home, keeping it cool in the summer and warm in the winter. Eagle Platinum tile also resists the growth of algae, bacteria, mold and mildew, and it boasts a non-toxic, water-based paint that is both non-flammable and resistant to ultraviolet light. Eagle's concrete tiles are breathable and do not allow condensation to accumulate. These tiles are available in almost all colors offered by Eagle Roofing Products.
While there are a few disadvantages of using concrete tiles, both homeowners and tile manufacturers can work to avoid them. The biggest disadvantage is the weight, as a concrete roof is heavy. Lightweight tiles are available, but they do not provide the protection of a classic concrete roof. Homeowners should have their house inspected in order to determine if it can handle the weight of a concrete roof. Concrete tiles also offer the disadvantages of needing a sealant and not holding their color, but manufacturers have produced sealants that are long lasting and provide ultraviolet protection to keep the roof's color intact.
