Permatex is a brand of sealers and adhesives used in the automotive industry. Permatex also has a branch of industrial-strength adhesives and patches designed for industrial usage. These are used for the repair of cement roof tiles and cement floors. This brand is Devcon, which sells a fast-acting concrete repair patch that can glue and repair concrete roof tiles as well as many other cement problems. In order to repair concrete roof tiles, apply the patch on a warm sunny day with a clear forecast for the next several days.

  1. 1

    Place the ladder against the wall in a sturdy and safe location. Clean the broken tiles with a chemical cleaner and a soft brush to remove any dirt, grease and contaminants from the tiles. Rinse the cleaner residue with clear water and allow the tiles to dry overnight.

  2. 2

    Mix the patch powder with the catalyst using a ratio of one to one. If the mixture is still too thick, then add a little more liquid. Stir thoroughly until the mixture reaches the consistency of peanut butter. Work fast, as the mixture starts to harden in about 15 minutes.

  3. 3

    Put on rubber gloves to protect hands from the patch material. Apply the repair patch to the broken tiles with a trowel. Press the broken pieces together and hold in place for one minute, or until they stick together like glue. Replace any missing cement pieces with a layer of the patch applied with a trowel. Use the trowel to smooth out any rough areas of the cement and to add shaping to match the texture and shape of the original tiles.

  4. 4

    Allow the patch to cure for 60 minutes before touching the roof tiles. A full cure takes 24 hours. Do not allow rain or weight to rest on the repaired cement tiles for 24 hours to ensure the patch has fully cured.
