According to comparisons between the types of tile materials, from slate to asphalt, a concrete roof tile has its characteristics. The lifespan of a concrete tile goes around 40 to 60 years. What makes this tile last that long? What makes it durable?

What concrete is made of

Concrete, the way you look at it and feel it, is a solid piece of a block formed into a tile. It is composed of three main compounds; sand, cement, and water. Some manufacturers add ingredients to concrete to extend its lifespan. A roof with a longer lifespan means it has high resiliency against extreme weather conditions.

Concrete, as described, is a mixture of cement (usually Portland), sand, and water and additional aggregates to strengthen the compound.

Portland cement

Generally used all over the world as the most basic yet versatile construction material is the Portland cement. Unknown to many, Portland is not a brand but an origin of concrete and how it is made of. Portland is just an ingredient of cement. It is also used in mortar, grout, or stucco. Portland’s roots came way back to the 19th-century England originating from limestone, and it was produced in a mixture of clay minerals and milestones through heating and grinding, with a little amount of gypsum.

Cement mixing.

The name “Portland” is derived from Portland stone due to its similarity. Portland stone was quarried in England in the Isle of Portland in Dorset. Portland cement comes in grey or white and can be a low-cost option roofing and construction material over the years, therefore, making it as the most versatile among the construction materials employed by builders and roofers.

The concrete made of Portland cement

Notice some confusing facts where concrete is regarded as cement and cement as concrete. For clarity, cement is a compound on its own; thus, the Portland cement, which is also produced using different components. Concrete contains only part cement, but it is the cement that defines concrete’s holistic characteristic.

Three types of concrete tile based on appearance and profiles

  1. Flat profile—flat as it is, no curves and bumps on the surface and design
  2. Low profile—appears to have small curves and bends as design
  3. High profile—appears to have ample curves and bumps as design

Based on these profiles, the surface of a roof tile can be rough or smooth, and it depends on the preference the homeowner or roofer for what is appropriate based on the other materials used to complete the roof membrane. In terms of colour, concrete roof tiles get their colour through integration rather than applying a paint coat. The colour is mixed with the compound to achieve different colours.

When it comes to weight, concrete roof tiles can vary from lightweight to standard weight. The cons of lightweight are their weak property as they tend to break when walked on or when exposed to heavy snow or hail. With standard weight, the strength is fair enough to withstand pressure from extreme weather. Other cause of breakage may come from fallen tree branches and poor integrity of the foundation.

When choosing between light and standard weight, consult your roofing contractor so that your money will be placed better on a smart decision.

How can you ensure a long-lasting concrete roof?

Even tile spacing and correct overlap of the roof. If you set up the tiles wrong, you will end up a roof where the tiles appeared too stretched to cover the small gaps. Too many gaps between tiles permit the water to leak.

Make sure the rafters and trusses are thoroughly clean of splinters or old nails that may damage the roof membrane. Roll out the roofing membrane over the trusses and rafters before you install other components. Attach the layer using galvanized nails not so hard on the trusses, just in the middle of the wood’s perimeter to avoid damaging the wood.

While a concrete roof can go as long as 60 or beyond, its life expectancy can be extended or shortened. In roofing, the establishment of a good foundation will affect the integrity of the rooftop. No matter how expensive or lavish your chosen tiles, it will invalidate its cause when the underlayment, starting from the rafters, trusses, membranes, and battens and flashing are poorly installed. Efficient engineering by an expert roofer is ultimately required before the concrete tiles are placed.

Even tile spacing and correct overlapping makes the roof waterproof. If you set up the tiles wrong, you will end up a roof where the tiles appeared too stretched to cover the small gaps. Too many gaps between tiles permit the water to leak.
