I first spotted a faint stain on the ceiling after a light shower and didn’t think much of it. But after a recent storm here, the stain darkened and spread, and I noticed a slow drip in the kitchen. I placed a bucket under it, but now I’m worried. Our tiled roof is over a decade old. I’ve heard small leaks can lead to serious damage if left alone. It doesn’t seem major yet, but it’s clearly getting worse. Am I overthinking it or is it time to call in a professional?
If it's leaking through, to a point where you need a bucket, yeah, time for a pro.
The hole in your roof is leaking on to the surface above the ceiling, which is saturated and now leaking through the ceiling.
Rot and mold are going to follow. You need to fix the roof AND everything hit by the water.
