7 Different Types of Roof Tiles for your Home
Roofing protects the building from mechanical impact and penetration of precipitation. The service life of a roof influences the overall durability and safety of the building’s structure, including the decorations and equipment, and depends on the correct installation of the external water shutoff roofing. The comfort of residential buildings largely depends on the reliability of the roof. Nowadays there are many variations of roofing materials that can surely secure premises from unwanted flooding.
Roof tile types
Roof tiles are naturally considered to be one of the most popular roofing materials that combine decorativeness with functionality. When deciding in favor of a certain tile type, you should consider the climatic features of the area, structure of the building, as well as your own preferences and financial capabilities. We can help you make a carefully considered choice by letting you take a good look at basic modifications of this roofing material:
- Metal tiles;
- Ceramic tiles;
- Concrete tiles;
- Bituminous (flexible) tiles;
- Polymer-sand tiles;
- Composite tiles;
- Copper tiles.
Metal tiles are suitable for use in many climates, since the material adapts well to sudden changes in temperature. This particular type of roofing material is used to cover new buildings as well as renovate the finished structures. Externally metal tile resembles traditional natural tile. Galvanized steel sheets are used for its production, they are primed and passivized (coated with a special protective structure that averts zinc from oxidation) from different sides. A decorative layer of acrylic paint is applied onto one of the sides; the other one is covered with a protective layer. Metal tiles are produced with a goffered, wavy surface or in the form of small scale-shaped tiles. One square meter weighs about 6.5 kg.
Such roof tile is used for brick, stone and wooden buildings, as well as for renovation of the old ones. The input materials are clays of different varieties, which are thoroughly mixed in certain proportions. Then the clay undergoes heat processing, which helps it to acquire the same density and an evenly distributed color. Coating does not affect the service life of tile, but it can dramatically change the appearance of the building. Currently, there are three types of ceramic tile available: flat, undulating and grooved.
Ceramic tile is fireproof and does not degrade after exposure to extreme temperature and sun. Such tiles have good heat and sound insulating properties. By means of contemporary methods of ceramic tile production, its surface is covered with color glaze, which makes it even more attractive. In modern stores you can find at least ten colors of ceramic tiles: blue, white, green, yellow, orange and others. The variations of tile types are very diverse and can satisfy even the most demanding customer. High frost resistance of ceramic tiles (more than 200 cycles) is worth noting too. The main disadvantage of ceramic tiles is that its large proportions set high expectations for the bearing elements of the roof.
Concrete tile is made of cement mortar (cement, sand, water). The manufacturing stages of this roofing material are simple: mixing of the components, formation of tile, coloration. Tiles are dried in a special chamber during a day, then the process is repeated, and then the completed tiles are kept to mature for about a month. The chemicals are not added during the process, iron oxide is used as a coloring pigment. The components do not harm human health, making it an eco-friendly material. In appearance, it is most similar to classic natural tile made out of baked clay.
Concrete tile has good strength properties, durability, frost resistance, as well as excellent sound and heat insulation properties. The disadvantage is large weight of the roofing material, which requires enhanced building constructions.
Bituminous (flexible) tile
Bituminous tile is a fiberglass or canvas made out of cellulose impregnated with bitumen. In order to provide ductility and strength to the shingles, polymeric additives are supplemented into the bitumen composition. The tile surface is covered with granite or basalt chippings on the outside. Chippings primarily create the so-called protective layer that provides additional strength and helps it obtain a special appearance. Such tiles are used on roofs with a slope of not more than 12 degrees. The lower surface is covered with tile adhesive, which greatly facilitates installation. You will not need any fixing materials such as screws or solution.
Polymer-sand tile is a technological product. This tile is made out of sand, which is bound with a polymer. The sand is the bulkiest part of the molding (up to 70%). Specially purified and calcimined river sand and various resins (thermoplastic polymers such as polyethylene or propylene) are used to produce quality tile. At high temperatures, the components are blended together, compressed into separate tiles and dyed. The components are mixed at a temperature of about 250 degrees, whereupon the obtained mass is poured into a special mold until it hardens.
Copper tile is noted for impressive durability and maintainability. The service life of this tile is more than 100 years. Within 10 — 12 years after roofing the copper tiles are covered by oxides and then by patina. In fact, it is one of the few types of roofing materials, which over time becomes only more beautiful.
Due to the small size of the elements you can use copper tile to carry out the installation of complex roof structures. The disadvantage of the described material lies in high prices and copper softness. In this regard copper roof installation must be carried out very carefully and the copper material should be not crumpled.
Composite tile is a quite new roofing material and a kind of metal tile. It has a multilayer structure; it is a 0.5 mm thick steel sheet, coated with zinc and aluminum. Acrylic polymer coating with stone chippings is applied to one of the surfaces. Such technological approach allows achieving the effect of a natural tile. The stone chippings significantly increase the mechanical strength of the coating. Thanks to this coating, the tiles obtain a fine aesthetic appearance and, therefore, it is widely demanded by consumers. The inner side of the tile is covered with acrylic primer to protect the metal from corrosion.

The cost of a concrete tile roof, on average, runs between $4.50 and $9 per square foot for standard-grade tiles, or $7-$10 for deluxe concrete tiles. A ceramic clay tile roof will cost a bit more—between $7 and $10 per square foot for lower-grade tiles, or as much as $10-$30 per square foot for premium clay tiles.
Maintenance and repair
Tile roofing should be regularly inspected for cracks or leaks, but should not be walked on if possible. Mold, algae and dirt can be removed from a tile roof quite easily with a power washer and cleaning solution of warm water and dishwashing detergent. Make sure not to target the power washer too close to the tiles. Just like any other material, the tiles run the danger of tear and breakage from weather, falling objects, freezing or movement. Fixing a crack in roof tiles is often easier than trying to replace the piece, and there are several ways to go about it.
