Paragon has decades of experience installing a wide variety of tile roofing. However, much of our tile-related work is identifying the source of water intrusion and providing comprehensive repairs. (This is because the tiles themselves typically last for a very long time.)
Cracked, broken or even missing tiles ought not, by themselves, cause leaks.
The primary "moisture barrier" on nearly all tile roofs is actually the underlayment beneath the tiles. If this underlayment was improperly installed (or becomes damaged), any water which gets under the tiles can cause leaks into the structure.
This underlayment is vulnerable to "solar exposure", as it is designed to by waterproof
but not withstand direct sunlight (which causes its deterioration; protection from the sun is provided by the tiles).
As a general rule, tile repairs begin by inspecting the interior to ascertain where the water intrusion is showing itself. This is followed by inspecting the roof itself in order to determine how the water is getting beneath the tile.
Occasionally, the solution is fairly easy to address. More often, it will require replacement of the underlayment on a section of the roof from wherever the leak evidences itself inside all the way up to the peak of that roof section. (This is because the tiles don't permit a simple visual inspection of the underlayment to ascertain the precise source of the leak.)
As such, proper tile roof repairs are generally not "quick and easy"; the leaks are often the result of improper installation which may not become apparent until several years have passed. A couple of common examples of this are:
1) Insufficient overlap of the tiles. Most often seen at HOAs or other large developments, this is a result of the installer not using enough rows (or "courses") of tile to overlap the tiles in the immediately preceding row. Over the scope of a large project, this saves a non-trivial amount of money on materials.
Unfortunately, it also often permits short daily exposure of the underlayment to direct sunlight. Over time, the exposed areas of underlayment will deteriorate.
2) Improper cutting of tiles along roof valleys. If tiles are not correctly trimmed along valleys (i.e., a sufficiently wide channel, jagged edges, etc.), this can cause accumulation of debris such as leaves and pine needles which impede drainage. With enough debris, even a moderate rain can cause water to back-up along the valley and get beneath the valley metal and/or underlayment.
