Ron Williams, “Roof Doctor” has been involved in the Roofing Industry for over 40 years.

We do more of this type than all others combined and there is nothing on a that we cannot fix.

Without question, the most common cause of leaks with today’s tile roofing is debris accumulation on top of and more importantly under the tile at the roof valleys and other flashings. Above you see a “closed” style tile roof valley. Now days all of them are done this way and when installed in this fashion are highly prone to debris build up under the tile which in turn causes roof leaks.

Tile Roof Leaks

On a tile roof, it’s these “pan” type or “J” flashings that are intended to keep the water from exiting or spilling over the edge of the flashing. There is a lip at the edge of the flashing that keeps water from running over the edge and off the flashing. If anything happens to that lip (it gets bent down or some installers even nail it down) even a minimal amount of dirt, mud, moss or leaves will divert water off the flashing and it will cause roof leaks. The big problem is, that since most roofers are paid piece work and the work itself is brutally tough, by the time the roof is done the lip on the valley is mostly flattened. To the left you can see multiple “mud lines” where little dams were created and water was diverted sideways off the flashing.

In addition, sometimes homes are actually built with the wrong type or size of flashings used. Either way, the end result is a roof leak and roof repairs are next.

Dirt build up creating dams


To the right can you see how over the years, the roof tiles themselves have been catching dirt that washes down the valley flashing, Eventually building up enough to create a dam and divert water over the flashing lip / edge and under the roofing, causing a roof leak.

This is when you find out that it is not the felt that keeps the water out as so many Contractors and “experts” mistakenly believe. If it was, none of these roofs would leak.

On a “closed valley” because the tile extends all the way to the center of the tile valley, it creates two problems. It smashes down the flashing edge/lip because it is sitting right on top of it. It catches all of the dirt / debris that is carried down the valley flashing with the water and accumulates until it creates dam, at which point it is diverted sideways over the flashing edge.

Straightening the pan

Here we have exposed and cleaned the valley flashing and are in the process of straightening the pan that was damaged by the tile being installed on top of it.

Batten Extender

Now we put the batten extender in place. It bridges over the flashing edge or lip, protecting it from being smashed down by the tile. It also holds the tile off the flashing, allowing water to flow underneath the roof tile even when there is debris on top of the tile.

Tile Roof Repair in General …

In summary I would say that in my opinion, overall tile roofing is a great product. It is widely known as a good looking, high end roofing material that usually comes with a 50 year or even lifetime materials warranty.

That being said, being a 25+ year roofing contractor I can tell you that 75% of our roof repair work is done on leaking tile roofs.

This is not due to any defects in the product. Tile roof leaks are mostly caused by a lack of roof maintenance. Tile roofs are sold as the “Cadillac” of roofing, with lifetime warranties etc. and the maintenance issues are seldom discussed until after the fact when they have become all too apparent.

With 75% of roof leaks being on tile roofs, 95% of those are caused by debris accumulation around roof penetration flashings like plumbing or heating pipes or roof intersection flashings primarily roof valley flashing or roof to wall flashing.

There are very specific guidelines for tile roof installations and that definitely include flashing. Still, sometimes builders will cut costs by installing a cheaper or even the wrong type of flashing which inevitably leads to roof leaks.

Even when the roof is installed correctly, normally after about 6-10 years, a tile roof will develop leaks at a roof valley because of dirt build up. This build is usually not visibly apparent since the bulk of it is actually under the roof tiles. If your roof should develop a leak near the valley area you should have it checked right away because these type of roof leaks once they start can get severe fairly quickly.
