A tile roof adds a touch of class to any structure. One that was installed correctly and is maintained on a regular basis can last three decades or more. However, a number of problems can develop with tile roofs as time goes by. Let’s examine some of them.
Cracks and Breaks
A crack in even a single tile can let in rain and swiftly damage the roofing. Breaks are even worse. Many things can cause cracks, breaks, and warping. Most often, the culprits are severe weather events. But tiles can even be cracked and broken by someone walking on the roof!
Cracks and breaks are usually visible during inspections. Another clue is that you are seeing moisture spots on the ceilings of interior rooms. Whatever the cause, cracked and broken tiles are best replaced by professionals.
Rotting Underlayment
Rotting underlayment beneath tile roofs is a common problem. The rot can spread rapidly and compromise entire sheets of sheathing if not addressed fast. It can be caused by rain leaking in through cracked and broken tiles, poor ventilation in the attic, or simply the age of the roof. If rain is leaking into your house during thunderstorms, the underlayment in at least one spot in your roof is totally rotted out.
Slips and Shifts
Tiles on a roof are held together by fasteners. Sometimes, these slip or break, and entire tiles move. Sometimes fasteners don’t stay fastened because they were installed incorrectly. Another issue could be cheap hardware that has fallen apart over time. Flashing around vents, chimneys and skylights can also start to leak due to aging or exposure to violent weather.
Resolving these problems is not a job for a do-it-yourselfer. You need to bring in professional roofers to do it right. Tile roofs are more complicated than asphalt ones, so you may have to talk to a number of contractors before finding a qualified one.
Algae and Moss
Algae and moss build up on roofs over time and trap moisture, which damages the roof itself. Accumulated debris on the roof hastens this process. Moreover, a lot of algae showing on a tile roof detracts from the house’s curb appeal. Fortunately, cleanings by a professional every year or so can rid your roof of moisture-laden, unsightly algae and moss.
Tile roofing represents a substantial amount of your investment in your home. Knowing these common problems is key to spotting them and resolving them fast before they become more serious.
