Clay tile roofing is well-known for its durability and distinctive look, but it requires regular maintenance to keep it in good shape and extend its life. Clay tiles are naturally resistant to fire, rot, and insects, but they can still be vulnerable to cracking, chipping, or breaking due to heavy impacts or extreme weather. Over time, moss, algae, or debris can build up, potentially causing moisture retention that might damage underlying layers. It’s a good practice to inspect your clay tile roof at least twice a year, ideally in spring and fall, looking for broken, loose, or missing tiles, as well as clogged gutters or signs of moss growth. Simple diagnostics involve a careful visual check from the ground with binoculars or walking safely on the roof if you're comfortable and knowledgeable about roof safety. During this inspection, avoid walking heavily on the tiles, as clay tiles can be fragile under direct pressure, and avoid using harsh chemicals or power washing, which can cause damage.
If you find minor issues such as a small cluster of broken tiles or moss, you might consider gently cleaning the affected areas with a soft brush and a mild cleaning solution, or replacing a few broken tiles yourself if you have the right tools and safety equipment. However, for larger cracks, significant tile displacement, or if you’re unsure about the roof's structural integrity, it’s wise to call a professional roofer who specializes in clay tile. When talking to your contractor, it’s helpful to ask, “Are the existing tiles still covered under a manufacturer’s warranty, and will repairs affect it?” and “What cleaning and repair methods do you recommend that protect both the tiles and underlayment?” These questions help ensure that any work done respects the roof’s design and warranty conditions.
