Asphalt Roof Tiles and Stone-Coated Roof Tiles
Roof tiles come in many varieties like asphalt and stone coated tiles. Both of these types have their advantages and disadvantages.
There are basically two kinds of asphalt roof tiles: organic (paper-based) and fiberglass. This depends on the material used as a base on which the asphalt is attached. Organic tiles are usually waste paper saturated with asphalt and ceramic granules to make it durable and resistant to both water and algae. The downside to this type, however, is that it is vulnerable to fire damage.
The fiberglass variety uses a mat base of glass fiber, which is then coated with asphalt and other mineral fillers. The resulting roof tile is also resistant to water. Compared to the organic variety, it is better able to resist fire damage due to the material used. The more expensive kind of fiberglass asphalt tile is the laminated roof tile. This is composed of two fiberglass layers with asphalt used as a sealant to bond both together. It is also called an architectural asphalt shingle.
Based on what asphalt tiles are made of, they are not expensive and easy to install. However, they last longer in places where the ambient temperature is cool as opposed to places that are warmer. This type of shingle is also susceptible to sudden rises in temperature, called thermal shock. The warranty for these tiles range from two to five decades depending on how well they are manufactured.
Stone-Coated Metal Roof Tiles
The construction of these tiles is similar in principle to the asphalt tile, with the big difference being its base, which is metal. It therefore has the water resistant properties of an asphalt tile. On top of that, it also has the advantages of having metal, such as steel, at its core.
This type of roofing tile is resistant to fire, wind, and hail. Because of its stone covering, it has the same aesthetic qualities as an asphalt tile. Despite being made partially of metal, it is lightweight and needs little maintenance. However, it is susceptible to thermal expansion when exposed to high temperatures. This causes an undesirable movement in the installed tiles. It is thus important to have an expert install this type of roof tile.
It is also considerably more expensive when compared to an asphalt tile. It costs twice or thrice that of a typical asphalt roof.
With the right installation and maintenance, asphalt is the viable choice. United Home Experts has long experience in aiding clients choose the best type of tile for their roofing needs and budget. Visit the website UnitedHomeExperts.com or call for advice and an estimate.
