How to Fix a Leak on a Clay Tile Roof
A clay roof tile is often susceptible to leaks caused as a result of various problems in the tile or in the method of installation. The manner in which a leak can be repaired will differ depending on the cause of the problem.
Step 1 - Identify the Cause
Clay roof tiles may leak due to several
faults. While some problems go beyond the roof and are related to the other aspects of the roofing or installation
methods, some of the common problems regarding clay tiles are:
1.
Defective or worn out waterproof membrane
2.
Collection of debris in the roof valley
3.
Cracked tiles
4.
Broken tiles
To fix the leak, you will need to fix the
specific problem that applies to you. Keep in mind that clay roof tiles break
easily under pressure, so be very careful when walking on your roof to
determine the cause of the leak.
Step 2 - Fix the Membrane
If the problem is in the waterproof membrane, you will need to remove
all your existing tiles and replace the old membrane with a new one. Then,
re-tile your roof. You may need the help of a professional for removal and
re-tiling.
Step 3 - Remove the Debris
The roof valleys, especially the closed ones,
collect a lot of debris. More often than not, this can cause leaks in clay roof
tiles. In order to remove the debris such that there is no more leakage, you
will need to remove the tiles from the
valley, clean out the area, and then reinstall the
tile.
Step 4 - Fix a Crack
If you find that there are fine cracks in your tiles, you can repair the crack by applying
RT-600 on the tile using a caulk gun. Allow the sealer to spread over the
entire tile, and let it dry.
Step 5 - Fix Broken Tiles
Tiles that are broken or have large cracks
need to be replaced in order to fix the leak. For this, you will need to remove
all damaged tiles using the pry bar. Use a hammer to assist in the
removal, but be careful not to damage good tiles
