Concrete Roof Tiles

Most people only clean their concrete roof tiles when they have the intention of resealing and repainting them.

There have been various makers of Concrete roofing tiles over the years. Some have performed very well whilst others have performed poorly. These tiles creating more issues for homeowners than originally intended.

The reality is that Concrete tiles do in fact deteriorate. The general idea is that Concrete cures and hardens over time. However, the curing process for a concrete roof tile lasts around 12 months.

They Can Be Delicate

When you move concrete roof tiles onto trucks or roofs they can easily develop structural defects. So, they are usually not left alone to completely cure before being used. These defects mainly show up many years after the tiles are installed and cannot be rectified.

Concrete roofing tiles generate about 120 degrees of surface temperature, where the ambient daily temperature is 30 degrees (most summers). As a result, the surface of the tiles takes a hammering year in year out. With things like acid rain, wind or pollution all contributing to the wear and tear of the concrete tiles surface.

Initially, the surface of the tiles will oxidise and become quite powdery. Then, once the surface coating is gone, the sand cement component of the tile erodes away as well.

The surface of the tiles ends up sliding into the surrounding gutter system. This will soil in the gutter, limiting the flow of water through the gutters, downpipes and water tank. Finally, this eventually causes the gutters system to fail.

A good quality sealer and coating application will stop the surface of the tiles from deteriorating. And with a new colour also dramatically enhancing the appearance of your roof.
