How To Safely Walk Onto And Clean Your Clay Roof Tiles Like A Pro

Clay tiles do more than just add beauty to Mediterranean or Spanish style architecture — they are also one of the roofing materials that stand the test of time. However, you'll want to occasionally give them a refresh, and according to Andre Afsharian, Owner of Roof Repair Specialist Los Angeles, it's important to understand the risks involved with walking onto and cleaning your clay roof tiles. It's also one of the downsides to consider before choosing a clay tile roof.

"Walking on clay roof tiles is risky for both personal safety and the integrity of the roof," Afsharian exclusively told House Digest. "... While it is possible for a homeowner to clean their roof, it is generally recommended that professionals handle this task due to the dangers involved." The roofing repair expert explained that clay tiles can break under the weight of a homeowner, leading to multiple issues, including a costly repair or replacement and the potential to fall. "If a homeowner insists on doing this themselves, they must take extreme precautions," Afsharian warned. If you plan to clean your clay roof tiles, he advised wearing non-slip shoes, working on a dry day, and distributing your weight where the tiles overlap.

In his exclusive interview with House Digest, Afsharian said there are several steps you should follow if you decide to clean your clay roof tiles yourself. First, set up a secure ladder. "Ensure the ladder is stable and placed on a solid surface," he advised. Then, use a low-pressure washer or garden hose to wet the tiles before applying a cleaning solution. "A pressure setting below 1,200 PSI prevents tile damage," Afsharian noted. "Use a mild mixture of water and vinegar or a specialized roof cleaner to remove mold, algae, and dirt." Afsharian also said that scrubbing with a soft brush is ideal for cleaning especially dirty areas. Finally, thoroughly rinse the entire roof. "Make sure no residue remains, as chemicals can weaken tiles over time," the roof repair expert said.

Afsharian explained it's important to repair any damaged areas as soon as you notice them. "If any tiles crack during the [cleaning] process, they should be replaced immediately to prevent leaks," he said. The roof repair specialist recommended calling a professional if your roof has a high or steep pitch, fragile or aged tiles, or signs of structural damage. 

"Unless the homeowner has experience, proper safety gear, and confidence in their ability to navigate their roof, hiring a professional is the safest choice," Afsharian exclusively told House Digest. "Not only does this prevent personal injury, but it also protects the integrity of the clay tiles, ensuring the roof remains in good condition for years to come." This is especially true for those who live in an older home with clay roof tiles. "Older tiles can break easily, leading to costly repairs," he said. "... If there are visible cracks, leaks, or loose tiles, walking on them could cause further damage."

If you decide to hire a professional, there are a number of questions to ask your roofing contractor. Although you can find one who specializes in tile roofs, Afsharian said there are other pros you can call when it's time to clean yours. An exterior cleaning company that offers roof washing services or a local handyman service with experience in roof maintenance are options you can consider, but Afsharian cautioned homeowners to make sure they are insured to work on roofs. He told us the cost to clean your clay tile roof will depend on a number of factors. The overall roof size, tile condition, and your location all play a part. On average, Afsharian says a basic cleaning will cost between $1,000 and $2,500. If your roof needs mold or algae removal, expect to pay between $1,500 and $3,500. And if your clay tile roof needs extensive restoration or repairs, you should budget over $3,500 to have it fixed.
