Installing a new roof is expensive and unnecessary especially when minor repairs are sufficient. Roof tile can easily be fixed for significantly less amount of money compared to new installation.
To replace your roof tile, simply follow the following easy steps:
1.) Apply a clear roof sealant below a broken tile. Press the tile down firmly to mask the crack. Apply more sealant into the top of the crack and smooth the sealant with a knife.
2.) A roof tile that is broken beyond mending should be removed. Use a pry bar to lift the tile placed above the broken tile.
3.) Smash the damaged tile with a hammer. Pick the broken pieces and sweep away any debris.
4.) If your roof uses tile clips, attach one to the tile and the roof. It is advisable to check with whoever installed the tile on your roof for proper use of tile clip.
5.) Slip in a new roof tile and remove the pry bar so the top tile slides back into its position above the new tile. - eHow.com
