Those Pretty Tiles Are Quietly Failing
Citium Roofing Solutions ·
The tile is the armor. The felt underneath is the roof. When the armor cracks, look at the felt.
Drive Mission Hills, Granada Hills, or Northridge and you will see miles of concrete S-tile that still look “fine” from the street. Many of those roofs are on their original felt from the first Bush administration. Tile does not waterproof a house. Tile sheds weather onto paper, and paper has a birthday.
Citium Roofing spends a lot of tile appointments talking owners out of two mistakes: ignoring cracked tiles, and ripping off a good tile field because one valley stained.
Why Valley tile cracks
- The product got brittle after decades of UV on the exposed edges
- Someone walked the roof in the wrong shoes
- Broken tiles were never reset, so the next row took the load
- Wind-driven debris during Santa Anas
- Cheap prior “repairs” with the wrong profile
Repair is enough when…
- Damage is clustered (a path to the HVAC, a corner the tree hits)
- We can still match or reasonably blend the profile
- Underlayment samples come up pliable, not powder
- Flashing at chimneys and sidewalls can be rebuilt without a full strip
Replacement (or full strip-and-relay) is the honest job when…
- Felt tears like grocery bags
- There are wet rusty nail heads in multiple zones
- You cannot buy a visual match and the field looks like a patchwork quilt
- The house is being re-sold and the inspector already called the system
A full tile job is labor-heavy. That is why it sits in a different band in the cost article. Sometimes we salvage tile, replace felt, and relay. Sometimes the math says new concrete with a current cool and Class A listing.
If you can see cracked caps from the driveway, do not wait for January rain. Have the underlayment checked.
