roof leak vs condensation 2

It's a common puzzle when you spot water stains on the ceiling. A roof leak is obvious when there's a drip after a storm, but condensation feels like a mystery—it's moisture from humid air meeting a cold surface, often appearing in winter. Try feeling the wet spot; if it's cold and the roof above is dry, it's likely condensation. If the wood is damp nearby, you probably have a leak.
