Step By Step Guide To Roof Repairs
How To Fix A Leaking Roof
This tutorial in the services teaches you how to fix leaks in your roof. A leaking roof can be caused by many things, this lesson will teach you how to replace broken tiles which may be the cause of your leakage.
Terracotta clay tiles are the most common and popular roofing material in homes built in Australia. Tile roofs are designed in such a way that water is able to run off the roof, by running off the end of one tile onto the next tile and so on. However, as a result of a crack in one or more of the roof tiles, water seeps into the crack instead of running off onto the next bile below the cracked tile.
This is how leaks occur. Fortunately, whether a tiled roof is chipped or cracked, you can repair it yourself in some cases.
Tools You Will Need:
- Replacement Tiles
- Caulk Gun
- Copper Nails
- Copper Strap
- Pry Bar
- Tile Roof Sealant
First and foremost, it must be determined whether or not an entire tile or multiple tiles need to be replaced completely. If you are unsure of how to locate the problem you may need to contact a professional roofing contractor who specialises in roof repairs. If a tile has just a small chip or crack, then it will be likely that the tile can simply be mended instead of being replaced entirely. A small chip or crack can be fixed by using caulk gun with a tile roof sealant. A small layer of the sealer should be placed into the chip or crack and it should be allowed to flow slightly over the chip or crack. Upon hardening, the sealer will completely seal the chip or crack.
Unfortunately, repairing a small chip or crack by simply coating with a layer of sealant does not result in preventing the roof from leaking. At times, leaks in the roof can only be fixed if broken tiles are replaced because they cannot be repaired.
If a roof has a tile (or tiles) that is so broken or damaged that it needs to be replaced, then it will have to be removed first. The tile will have to be gently pried up using a pry bar in order to do this. If the tile is not lifting and rising, then a hammer can be used to break it and remove it easily. If the hammer option is used, it should be made sure that the tile is broken up gently so that the surrounding tiles do not get broken or disturbed.
Once the tile has been removed of the roof, then it is time to get the new tile ready to be replaced. If your tile roof is over 50 years old, then it is likely that none of the tiles are nailed to the roof in any way. Back then, nails were never used; instead, clay tiles were simply mortared. If the tiles are indeed mortared, the new tile will just have to be slid into place and then a concrete seal can be created by mortaring all around and underneath it.
If there are nails that were securing the tile in place, a hanger strap will have to be hung on the new tile to prep it to take the place of the previous tile. There should be an L-shaped bend in the strap. In that case, the bottom of the L will be hanging onto the tile while the bottom of the L will be hanging onto the roof’s hanger board just beneath the next tile above the one that is being repaired. Once the new tile has been slid into place, the bracket or hanger strap will not be visible.
Finally, once the hanger strap has been set in place on the tile, it can be hung on the roof in the appropriate spot. The new tile does not match up with the other ones; it will have to be trimmed down a bit using a wet saw. The new tile should not be forced into place as the other tiles may get broken as a result.
A nail can be used to complete the replacement of the clay tile, which should be hammered into the hole in the tile that is above it. This way, the tile will be secured to the roof. For additional security from leaks, you can apply mortar to all edges of the tile so that a watertight seal is formed.
The Wrap Up
Once the repair has been completed, the roof should most likely not leak anymore. However, if the problem continues to persists, then I would recommend you call a professional roofing contractor to get the leak repaired correctly. Nonetheless, replacing or repairing a broken or damaged tile should fix a leak in the roof, as long as the above steps are followed, whether a tile can be repaired using a sealant, or needs to be replaced entirely.
