A Tile Roof should last forever, Right?
I know you hate these answers...Yes and No.
The tile itself will stand the test of time, however the tile is not the waterproofing component of a Tile Roofing System. The tile portion of your roof system does facilitate water shedding, but it is what is under that tile that keeps you water tight. The tile underlayment that sits between your wood decking and the tile is the critical waterproofing component and this barrier does not last forever.
Unlike Shingle and Flat roofs that show its wear and tear, the aging component of a tile roof is not evident as it is being covered by that beautiful long lasting tile.
So now what? The best way to know where you are in the life span of your tile roof underlayment is to pull up a few tiles and look. The aging of the underlayment is detectable, you should see flexible sturdy material, not brittle or degrading.
There are also areas most likely to degrade first- check those dead valleys where water has not outlet and debris tends to gather. Those areas should be kept free from debris as that debris accelerates the degrading of your underlayment by holding onto water and moisture.
What if your underlayment is beyond its useful life- Do you need a new roof?
Again, not a clear answer. Our first recommendation would be to do what we call a Tile R&R. That is we Remove the tile, correct the underlayment problem, the Replace the existing tile. This process is available to most tile roof types with the exception of Mexican clay that is too fragile for this process. Now, here is the tricky part, when we remove that tile- it is expected that a certain percentage of those tiles will not be reusable. (the percentage depends on the method by which they were originally installed). If that tile is still being manufactured then we can simply purchase that same tile for replacement of those unusable tiles. However...during our recent economic crisis many tile manufacturers have gone out of business-and with them went their proprietary colors and molds. If you roof was constructed with those obsolete tiles- then we need to get creative- perhaps doing a section not visible to the street with one tile and the remainder of the roof in another. The front one tile, the back another. You will need to partner with your Project Specialist to make these decisions.
