Replacement of roof tiles that have cracked, broken or disappeared is important to prevent roof leaks an ceiling damage once rain and wind appear. Fixing the problem quickly by yourself is possible provided it’s only a few tiles.
Prices for tile changing can be expensive and vary depending on the company you use. What most people don’t realise is that as long as you can find the appropriate tile and have a decent ladder, you can change it yourself with minimal effort.
Ensure you have the correct replacement tile as there are many different roof tiles on the market. The most common tile types are concrete and terracotta. You must ensure it is the same type of tile or it may not work and can result in damage even though you've tried to repair it. If you don't know what the tile is, take a tile with you to a roofing supplier and they should be able to match it for you.
Get onto the roof. Only do this if you know it can be done safely, using a stable ladder and perhaps even using climbing ropes to protect you in case of a fall, particularly with a roof that has a steep incline or is slippery. If you don't have a head for heights or you're not sure about how safe it is for you to get on the roof, call in a professional. Falling off a roof can be deadly.
Once you have safely gotten to the broken tile, you'll need to slightly lift the tiles that overlap the one to be removed. Do this using two pieces of timber to hold them up. Then, use a brick trowel to lift up the broken over the baton underneath and slide it down and out.
Place your new tile onto the brick trowel and reverse the steps for removing the tile. Be sure to place the overlapping tiles back into position.
Ensure the tile is securely in place and is not interfering with any other tiles around it. Unless you're in a high wind area, the tile won't need to be nailed or wired into place. Check that all tiles are sitting properly.
Have a quick check across the roof while you're there to survey any other potential damage. It's a good idea to know how well the roof is holding up in case any other tiles need replacing.
