The Popularity of Concrete Tile Roofing Contractors Near Me
The concrete tile roofing contractors near me are popular in Southern California, where most of the houses are roofed using concrete tiles. Until about 50 years ago, almost all of the roof tiles installed in the United States are clay tiles, similar to those used in the roofing of various houses in Europe and China thousands of years ago. In the past few years though, the concrete roofing tiles have started to edge out clay roofs for their houses and today, the material has already dominated the market.
Roof tiles, where they are made of clay or concrete, are known to be very resistant to heat and fire. Although some of those who consider themselves traditionalists would prefer clay tiles over concrete tiles, there is no doubt that the main advantage of concrete tiles is that they cost about half as much as the clay tiles.
Concrete Tile versus Clay Tile
The biggest advantage of the concrete tile over other tile roofing, especially clay tiles, is its low cost. Those who prefer clay tile roofing, including the terracotta clay tile roofing contractors, will usually mention two advantages of the clay tiles over concrete tiles – longer physical durability and better colorfastness.
- Durability – well-made concrete tiles are guaranteed to last for a long time, although probably not as long as the clay tiles. Experts estimate that the material could last up to 50 years for as long as it is maintained well. In contrast, a lot of the European clay tile roofs are still waterproofed even after a century of use. Traditionally fired clay, although it is relatively easy to break, will not degrade even from its exposure to the outside elements. Since the objects that are made from fired clay cannot burn or rot, they are among the most durable materials known in archeology. The clay objects could easily last for up to a thousand years.
- Colorfastness – the color of the clay tiles is not affected even with exposure to outside elements. But the same cannot be said for concrete tiles. Although most of the concrete roof tiles are manufactured with having an integral pigment that will provide color to the entire thickness of the tile, the color of the concrete tiles could fade over time. The concrete tile cannot hold its color well unlike the clay tiles.
Although some of the early concrete tile roofing come with durability problems, most especially on those areas that experience frequent thaw and freeze cycles, most of the manufacturers of concrete tile roofing claim that the concrete tiles of today are more durable and consistent than ever. Although there have been reports about isolated cases of concrete roof tiles that have seriously deteriorated, tile manufacturers have claimed that such problems are very rare and will happen only if a batch of bad tiles can pass through their quality control system.
However, these are very rare cases. Several tile roofing contractors can attest that manufacturers are very careful in the manufacturing of the concrete tiles. They would never allow any bad quality of concrete tiles to be able to get through their quality control system.
Consider the Weight of the Tiles
Concrete tiles that have standard weight generally weigh between 9 ½ and 12 pounds for every square foot. They weigh significantly more than the asphalt shingles that weigh only at 2 ½ pounds to 4 pounds of every square foot.
For houses where weight is a major concern, a lot of tile manufacturers will produce lightweight roof tiles that produce lightweight tile roofing that weighs only between 5 ½ pounds up to 7 pounds for every square foot. The tiles are usually manufactured using lightweight aggregates, such as expanded shale, instead of the usual sand.
If you are re-roofing a house that has existing asphalt shingle roofing and you are not sure whether the roof structure is enough to support the concrete tiles, you must let an engineer check the roof framing before proceeding with the installation.
Concrete roof tiles have three basic profiles – mission S tiles, Villa tiles and flat tiles. The mission S stiles is also known as Spanish S. The villa tiles are known for being a low profile tile that comes with a double S shape, while the flat tiles are often designed to resemble slates or shakes.
Concrete tile manufacturers produce trim tiles that are specially designed to complement well with the various tile profiles. Most of the roofs will require having at least two different types of tiles – the standard field tiles and the ridge tiles.
For jobs that make use of S-tiles, the contractors will usually trim the hips, ridges and rakes using a simple barrel trim tile. Some of the styles of concrete roof tiles will be using a rake trim tile that is usually different from ridge tiles. Some of the manufacturers will also offer a hip starter designed tile, which is a trim tile that can be installed at the bottom tile into a hip.
Overall, the minimum slope for a tile roof is at 3 1/2. If the homeowner will insist on installing concrete roof tiles in a roof having a pitch below 3 1/2, it is important to consult the tile manufacturer for the installation specifications.
Low slope applications will often require a waterproof membrane under tiles that’s carefully detailed. For instance, a self-sticking bituminous membrane can be used. In addition, a lot of tile manufacturers would require that the tiles in a low slope roof to be installed in a method that helps to minimize the number of fasteners that would penetrate deep into the membrane.
The concrete roof tiles can be installed on battens parallel to the eaves or directly nailed into the felt that’s covered with plywood or into OSB sheathing. A lot of local roofing contractors would say that you could achieve excellent success if you will directly nail the concrete roofing tiles.
Most tile manufacturers would agree on direct nailing, except on roofs having a pitch steeper than 7 1/2 or on very cold climates that are often subjected to ice dams. When the battens are used, they are usually 1 x 2, where one course of batten is used for each course of tiles. It is important that you leave a gap of about one inch in between the ends of the adjacent battens so as to allow a gap for water to be able to drain well. The battens must not be longer than 48 inches, for similar reason.
Among the most important tools used for installing the concrete roof tiles are gas powered cut-off saw, nail gun, or a circular saw that has a diamond blade. Sometimes, a leaf blower for cleaning the dust off may be required.
It is important to remember that roof tiles are not totally waterproof. In a driving rain, some of the water will most likely to get pass through them. Thus, the concrete tile roofing contractors near me that you will hire might need to first install the asphalt felt very carefully. The concrete felt is the most important waterproof layer used for a tile roof.
