Regardless of whether your roof is made up of tiles of shingles, as long as these materials are comprised of concrete, there are some steps you need to take to ensure an appropriate level of protection.
A roof made of tiles features a high risk of leakage, moisture can easily seep into the concrete material, which can, in turn, leak into your home. Contrary to appearances, concrete is a naturally porous material. Its mixture of water, Portland cement, and aggregate (such as stone, gravel, or sand) leads to tiny pores and hairline cracks that extend throughout the concrete.
These air pockets are often too miniscule to see with the human eye, though the surface pores that begin the networks of cracks and pores are often clearly visible. Whether from snow, rain, or melting ice, water can seep into the concrete through the surface to make its way through the network of cracks and pores until it leaks out the other side. The concrete becomes saturated with water, and the liquid has nowhere to go but downward into your home.
Fortunately, it is easy to protect your concrete roof tiles thereby protecting your home from water damage. The best, most cost-effective method is to apply a concrete sealer to your roof in order to prevent water leakage. Siloxa-Tek 8500 or Siloxa-Tek 8510 are the best options to protect your roof, especially in salt water environments. They are penetrating sealers that will impregnate the concrete roof tiles, and protect them from degradation, carbonization, salts and corrosion. Penetrating concrete sealers like these are an inexpensive and straightforward way to prevent future damage to your home, all while helping to prevent mold, mildew, efflorescence, and other problems that can threaten a houses integrity.
