A clay tile roof is durable and has a long life. That doesn't mean a tile roof won't leak and need repairs. If cracked tiles are patched before they break apart, you can save on the cost of repairs and minimize roof damage. However, if you first learn of roof trouble when water drips from the ceiling, you probably have more than a minor crack to repair. Here's a look at the process of repairing a leaky clay tile roof.
The Leaky Area Has To Be Found
It isn't always easy to find out where a tile roof is leaking. Since you can damage tiles easily when you walk on them, it's best to hire a roofer to find the leak. They will look for cracked and broken tiles as well as loose gaps in flashing. Flashing is always a likely suspect since the adhesive can deteriorate with age and let rain leak through. The roofer might have to use an infrared camera or moisture detecting equipment to pinpoint the source of the leak. Once that's done, then a plan is made for repairs.
Replace Flashing If Needed
If the leak is caused by a loose seam in flashing, then it might be necessary to remove the old flashing and install new. The new flashing has to be installed so it overlaps properly and rain drains away. Sealant is also added to keep rain from seeping under the tiles.
Repair Or Replace Damaged Tiles
If the leak is coming from damaged tiles, then the roofer has to decide if a tile can be repaired or if it has to be pulled out and replaced. Broken tiles and tiles with large cracks are usually replaced. Once the tiles are off, the roofer can take a look at the underlayment and deck to see if they need to be replaced too due to water damage. If so, part of the deck is cut out and new decking put in before new underlayment and tiles are added.
Replace The Underlayment If Needed
If the underlayment is damaged, it might be an isolated problem due to the leaky tiles. However, it's also possible the entire underlayment is bad and needs to be replaced. This can happen when your tile roof gets old. The tiles last much longer than the underlayment, so there may be a point where it's necessary to take the tiles off and put down new underlayment to prevent water leaks. Your roofer can help you decide if replacing the underlayment is necessary and a good use of your money considering it might save on future roofing repair bills.
