How Long Do Concrete Roof Tiles Last?
Concrete tile roofs are a popular and durable type of roof known for their fire-resistance and ability to be molded into various shapes and colors. Their versatility and ease of use make them a top choice for homeowners and builders when considering the type of roof for a new building or renovation project.
They have a lot of enticing features but, before committing to any roofing material people usually want to know how long they’ll last and how often they might need to replace them when they finally pick one. In this article, we’ll explore the factors that contribute to the lifespan of your roof, their expected average lifespan, and some common signs of wear and tear to look out for.
What Is the Expected Lifespan of a Concrete Roof Tile?
Concrete has a long lifespan is a sturdy roofing material. It can last 25 years up to 50 years, and maybe even more with proper care and maintenance. The expectancy of 50 years for tiles is considered to be average, however, factors such as harsh weather conditions and lack of maintenance can shorten the expectancy of roofing materials like asphalt and types of asphalt shingles may require a new roof or roof repairs. Tiles over time can also be affected by the elements, such as sun exposure and moss growth, which can cause fading and damage to the tiles. Regular maintenance and inspection can help prolong the life of your roof tiles and save you money on repairs in the long run. Tiles also require proper installation by a professional roofing contractor to ensure that they are installed correctly and will last well over time.
Weight
Concrete and clay roof tiles are two popular options for homeowners looking for a durable and long-lasting roofing solution. While clay tiles can also be more expensive than concrete roof tiles, they are significantly heavier. Concrete roofs, also known as cement roofs, can weigh anywhere from 600 to 1,100 pounds per sq. (100 sq ft) and when combined with clay, they become one of the heaviest roofing tiles available. To support the weight of a clay and concrete roof, the framework and frame of the building have to be strengthened significantly to ensure the longevity of the roof and prevent the need for expensive roof repairs. Tiles can easily be damaged if not properly supported, so it is important to ensure that the structure of your home is able to support the weight of a concrete or clay roof before installation.
Weatherproofing
To perform optimally and withstand various weather conditions, including extreme weather, concrete tiles need to be treated to ensure their durability and longevity. This prevents water absorption as much as possible, as it is a porous material and when placed in a moist environment it begins to absorb water. Applying a sealant to concrete tiles will prolong the life of the tiles by stopping the accumulation of moisture, which can cause mildew, mold, and possibly degradation of the roof’s underlayment. This protects the roof from moisture and prolongs the roof’s durability in different harsh weather conditions.
Underlayment
A roof’s underlayment, which is typically used for around 20 years, has a shorter underlayment last compared to the concrete tiles that cover it. This means that while the overlaying tiles might last as long, the underlayment might need to be removed and then replaced. This is a lengthy and complicated process when you consider the weight and the installation process for concrete tile, which can be challenging to remove and replace without causing damage to the tiles. It’s important to remember that the underlayment is an essential part of your roof and it should be checked and maintained regularly to ensure that the tile roof last for as long as possible.
Efflorescence
This is a natural process that takes place when free lime, which is a component within it gets exposed to the elements of water as well as calcium hydroxide. This reaction creates a white, chalky deposit to develop on the roof when it’s exposed to the carbon dioxide in the air. This chalky deposit doesn’t impact the strength or longevity of the roof and sometimes it eventually disappears. It doesn’t have a direct impact on the roof’s expectancy but, it can make the roof appear more unattractive, older, and worn-out than it really is. However, with proper maintenance, your concrete roof may last for many years despite this natural process.
Maintenance
Concrete roof tiles are a durable and long-lasting option for your roofing needs, but regular maintenance is necessary to ensure that they meet their full roof life expectancy and to keep them functioning optimally over time. Maintenance involves applying the sealant to make sure that they are water resistant, removing the moss, mold, or mildew from the surfaces and between tiles, and replacing cracked or broken tiles. Since they shouldn’t be walked on, it’s essential to avoid DIY maintenance techniques as much as possible and hire an expert when maintenance is required. The color of the tiles is another important factor, to stop the color from fading, they must be painted regularly. Materials like asphalt and metal roofs may require less maintenance, but they don’t have the same durability and longevity as concrete tiles.
Common Signs of Wear and Tear on Concrete Roof Tiles
Concrete roof tiles are a durable option for your roofing needs, but over time, they may start to show signs of wear and tear. It’s important to identify these signs early on so that you can take action, make necessary repairs, or even consider a roof replacement before they become bigger problems. Here are some common signs of wear and tear:
- Cracks: Over time, concrete roof tiles may start to crack due to weathering, thermal expansion and contraction, and other factors. These cracks can weaken the structural integrity of your roof and allow water to seep in, causing damage to your home.
- Fading: Sun exposure can cause concrete roof tiles to fade over time, affecting their appearance and reducing their overall lifespan.
- Moss and Algae Growth: Concrete roof tiles are porous, which means that moss and algae can grow on them over time. This can make your roof look unsightly and damaged.
- Loose or Missing Tiles: Due to wind, rain, and other factors, some concrete tiles may become loose or fall off entirely. If left unchecked, this can lead to leaks and other damage to your home.
- Discoloration: Concrete roof tiles can easily become discolored over time due to exposure to the elements. This can happen due to exposure to rain, sun, and other environmental factors.
If you notice any of these signs of wear and tear on your roof tiles, it’s important to have them inspected and repaired as soon as possible to prevent further damage to your home. Regular maintenance and inspection can help prolong the life of your concrete roof tiles and save you money on repairs in the long run. Tiles require routine cleaning and sealing to prevent damage from water and moss growth, and tiles also benefit from regular inspections for cracks or breaks. With proper care and maintenance, concrete tiles can last well beyond their expectancy.
How Can You Prolong Your Roofs Lifespan?
Prolonging the expectancy of your current roof is essential to ensuring the overall integrity and stability of your home. With a lifespan of 50 years, following these tips can help you extend the life of your current roof:
- Regularly inspect your roof: A regular visual inspection of your roof can help you identify any potential issues early on. Look for missing or damaged shingles, cracked or damaged flashing, and other signs of wear and tear.
- Keep your roof clean: Debris, such as leaves and branches, can accumulate on your roof and cause damage. To prevent this type of damage, it is important to regularly clean your roof by removing any leaves or branches that may leave your roof.
- Address leaks immediately: Any leaks or water damage should be addressed immediately. Ignoring leaks can lead to bigger problems down the road, such as mold and rot.
- Maintain proper ventilation: Proper ventilation is essential for maintaining the health of your roof. Make sure your roof has adequate ventilation to prevent heat and moisture buildup.
- Consider regular maintenance: Regular maintenance and repairs can help prolong the lifespan of your roof. This can include things like re-caulking flashing, replacing missing or damaged shingles, and cleaning gutters.
