A Spanish tile roof is durable and long-lasting, requiring only minimal maintenance. Even though the tiles are strong, they aren't immune to problems. It's important to know some of the common issues that may require a repair.
Stains can be quite unsightly on Spanish tile, but they won't cause any damage to the roof. Common causes of discoloration are moss, algae, and efflorescence. Moss and algae can be removed with the proper cleaners, and then a roofer can install zinc strip beneath the ridge cap to minimize the chances of future growth and stain. Efflorescence occurs naturally on Spanish tile. It is the result of lime and other minerals in the tile leaching out when the tiles are exposed to moisture. Fortunately, these stains will eventually fade once the last of the problem minerals leech from the tiles.
Although Spanish tiles are strong, they aren't immune to damage. Cracks, chips, and loosening can occur. These types of damage are most likely to occur following storms, particularly wind and hail storms. A damaged or missing tile may not seem like a major issue, but it can weaken the security of neighboring tiles and lead to more damages. Further, water can leak into your home via the damage. A roofer can easily replace any missing or cracked tiles so your roof is like new again.
Spanish tiles are durable, but that durability is in part due to the weight of the materials. Your roof is only as strong as the underlying structure that supports the heavy tiles. Periodically you need to survey the ridgeline of your roof to make sure it still appears level and straight. If the ridge looks bowed or if you notice any sunken areas elsewhere on the roof, you need to have the roof inspected immediately. Repairs to the supports beneath the bowed areas can fix the issue.
Damage to Spanish tiles may not be immediately obvious from the roof's exterior, but a visit to your attic can reveal a big problem. Signs of water leaks include soft, rotten trusses and roof beams, wet and moldy insulation, and a general odor of damp and mustiness. If left unaddressed, then extensive water damage can occur. Even worse, water rot can set in on roof supports and lead to a dangerous situation. It's a good idea to inspect your attic for signs of water leaks every month or two so you can have problems repaired promptly.
