Leaks around concrete tiles and skylights often happen because of issues where the materials meet or due to wear over time. Concrete tiles are heavy and durable, but their overlapping design means that if a tile cracks or shifts, water can sneak underneath. Skylights, being openings in the roof, have flashing and seals designed to keep water out, but these can degrade, crack, or get displaced. Causes might include weather damage, poor installation, or natural aging. Simple checks you can do yourself include looking for cracked or missing tiles, checking the sealant around the skylight for gaps or peeling, and inspecting the flashing for obvious damage. Inside, look for water stains or dampness near the skylight or in the attic. Using a garden hose to mimic rain, spray around the skylight area carefully to spot drips inside can help pinpoint leaks, but always avoid too much pressure.
If you notice damage or suspect leaks that you can’t fix safely, it’s smart to call a professional roofer. Leak repairs often involve carefully replacing broken tiles, resealing around the skylight, or reinstalling flashing. When you speak with a contractor, ask them if they are familiar with repairing both concrete tile roofs and skylights, and whether they check for underlying structural issues when fixing leaks. Also, inquire about warranty coverage—both on the repair work and any replacement parts—to make sure your investment is protected. Proper repairs keep your roof sound and prevent costly water damage down the line, so don’t delay if you suspect a leak.
