25 Roof Leak Warning Signs (With Photos) — When to Call a Roofer for Repair

Moment #5: Daylight through the roof deck

If you can see pinpoints of daylight from inside the attic, water can enter too. Tiny holes can form near fasteners, aging decking, or storm-damaged areas. These gaps often expand with wind and temperature cycles. Even if the leak seems minor now, repeated wetting can damage insulation and wood over time. This is usually a good reason to schedule a focused roof inspection.
