Roofing is primarily designed to keep water out of the underlying structure. Tile roofs aren’t mainly responsible for that. Although cement tiles (and clay ones) have overlapping and interlocking joints, a tile roof may not be completely waterproof. Rain that is blown by the wind quickly penetrates the tiles.
Underlayment, the moisture barrier below the tile, is protected from temperature extremes, ultraviolet light, wind, and moisture, which promote its deterioration. This guide is all about cement roof tiles with brief information.
Cement roof Tiles
A cement tile, also known as concrete tile, mimics the shape and appearance of clay at a fraction of the cost. The installation of cement tile roofs requires the expertise of an experienced professional, as with clay tile. Even though cement tile roofs are not as long-lasting as clay tiles, manufacturers estimate that they will last fifty years or more.
A cement tile stands up well to high winds and hail damage because of its weight and resistance to hail damage. Due to the need for a particular saw to cut the tiles individually to fit, it can be especially tricky and time-consuming (and therefore expensive) to fit cement tiles onto a complex roof design. This makes cement tile most suitable for roofs with vast expanses and few interruptions.
The advantages of cement roof tiles
· Average life expectancy
There is a possibility that concrete tiles may last for 30 to 50 years, which is not as long as clay tiles which may last up to 100 years but are still longer than most roof systems.
As a result of their versatility, concrete tiles can be used for both commercial and residential roofing systems. Whatever the case may be, there should be a minimum slope of 3:12, which means it should rise every 12 inches.
· The cost
Roofs with concrete tiles are more affordable than roofs with clay tiles. It costs about $40-$90 per square foot (100 square feet in one square) for clay tiles. In comparison to other tile roof options, it is much less expensive.
· Resistant to fires
Fire resistance is a natural characteristic of concrete tiles. This product has been rated as a Class a fire rating, the highest one available. As a result of this roof system, you will be protected from falling ash or embers in case of a nearby fire.
· Easy to maintain
Tiles made of concrete require little maintenance. Their maintenance requirements are a bit higher than those of clay tiles. If efflorescence or fading occurs on concrete tiles, the color may need to be re-colored.
The disadvantages of cement roof tiles
Some people do not prefer concrete roof tiles for the following reasons.
· An efflorescence
The porous nature of concrete roofs allows them to absorb more water than clay roofs. This causes a white chalky substance to appear on the concrete surface when water mixes with carbon dioxide and combines with the lime in the concrete.
Efflorescence is a term used to describe this phenomenon. There may be stains on the concrete, but they can be cleaned off. In addition, it can be sealed to prevent moisture from absorbing.
· Damaged ones cannot easily be replaced.
Concrete roof tiles are also hard to replace when broken or damaged, which is another reason some people do not choose them. As a result, homeowners will need to replace their concrete roof tiles, and if the original tiles have already corroded, replacements may cost more.
It is important to note, however, that what may be a pro for one person may be a con for another. Because every homeowner has different preferences and opinions, this is the case. To one person, an advantage may be a disadvantage, while to another, it may be a benefit. Think carefully before making your decision, weighing its pros and cons!
· They appear unattractive.
In comparison with other roofing materials like asphalt shingles or clay tiles, some people find it unattractive. In addition to their unattractive appearance, concrete roof tiles are not favored by some people due to their appearance. A building or house won’t look friendly to them, and they won’t add to its overall aesthetic appeal.
Concrete roof tiles are heavy, which is one of the reasons why some people do not choose them. Installing and removing them would therefore require more workforce and effort.
· Easily damaged again
Tiles made of concrete are more susceptible to damage than those made of other materials. Objects falling from the sky, hail, and strong winds can easily damage them. As a result, they will require more frequent repairs or replacements than other roof materials.
The lifespan of cement roof tiles
The lifetime of roof tiles is expected to be between 20 and 30 years. It is despite the fact that cement board is used to construct them that the cement board differs significantly from the concrete that is used in sidewalks and foundations. Compared to cement board roof tiles, concrete roof tiles are cruder in their manufacturing process, which reduces permeability and strength.
An asphalt roof tile comprises sand, wire mesh, and concrete layered on wooden supports. Another piece of plywood with the sand side facing up has been flipped over to cover the three layers of plywood. Loops are formed by driving metal rods into concrete underneath and bending them over.
The process is repeated to build up enough concrete until the desired level has been reached. This is followed by lowering a steel frame with attached heaters until the entire process is completed. After the concrete dries, the wood support is removed, and concrete roof tiles are formed.
There is no limit to how long concrete roof tiles will last on the house. It is important to choose a manufacturer who has a strong warranty and a reputable reputation. It is vital that the product you select is suitable for your climate and will withstand the natural forces that may affect your roof. Choosing an installer familiar with the manufacturer’s specifications is also essential.
FAQs (Frequently Asked Questions)
What is the best type of tile for roofing?
Between roof tile materials, clay and concrete have the most extended lifespans. Concrete and clay roof tiles can last for over 100 years, often outliving the properties on which they were installed. Another top-level choice for longevity is slate tiles.
Is concrete a good material for roof tiles?
The average cost of concrete roof tiles is approximately 20% less than that of clay roof tiles that are machine-made. However, concrete has other advantages, such as its ability to withstand extreme temperatures better than clay, which cracks or shatters in freezing weather.
Is clay roofing better than concrete roofing?
Unlike concrete roofs, which fade over time, a natural clay roof will retain its richness and character for the lifetime of the tiles. Concrete is more challenging to produce subtle imperfections and a diversity of textures, colors, and sizes than other materials.
