Common Signs of a Roof Leak

- Mold growth and musty odors: These can signal prolonged moisture presence, often associated with roof leaks.
- Dripping water during rain: This is a clear indicator that your roof is compromised and requires immediate attention.
- Sagging roof areas: Visible dips or sagging in the roof structure can suggest underlying damage or moisture accumulation.
Identifying the Source of a Roof Leak
Finding the actual source of a leak can be tricky, as water can travel along beams and rafters before it appears inside your home. Start by inspecting the attic and roof for any visible signs of damage.
