Roof Valley Leaks: What to Check and Ask
Takeaway: A roof valley carries water where two slopes meet.
Read the transcript
A roof valley carries water where two slopes meet. For an Edmond leak near this area, record the timing and affected room. The indoor location alone does not confirm a valley fault. Leaves and grit may interrupt runoff, but do not climb a roof to clear them. Ask a professional to inspect the valley and document both visible conditions and concealed-layer limits. Stains below the roof can help an investigation, but water may travel along wood. Keep people away from unsafe attic areas and ceilings that sag or bulge beneath active water. Valley repair can involve surrounding shingles, membrane, metal, or drainage. Ask which component failed and how the proposed work integrates with the existing roof rather than assuming clearing leaves is enough. Provide your ZIP, rain timing, and previous repair history. Request valley leak assessment with your observations. A photograph does not price the job, and saving a request does not confirm an appointment.

Common causes
What goes wrong in valleys.
- Worn shingles from fast-moving water
- Leaves and debris damming water
- Nails placed too close to the valley center
- Missing or torn valley underlayment
How it's fixed
Valleys usually need the shingles opened up, new ice-and-water underlayment laid, and the valley rebuilt. Patching the surface rarely holds.
Failure diagnostics: what to look for

Leaves packed into a valley
- What You See
- The meeting line between roof slopes carries concentrated runoff.
- The Hidden Hazard Below
- Leaves or worn layers may interrupt drainage. Hidden membrane condition needs professional evaluation.
- The Correct Repair
- Ask a roofer to check drainage, surrounding shingles and the valley lining. Stay off the roof.

Water stains on roof wood
- What You See
- Discoloration shows where moisture appeared, not necessarily where it entered.
- The Hidden Hazard Below
- Water can travel along wood before it shows indoors. Plumbing and condensation may also need to be ruled out.
- The Correct Repair
- Have the source evaluated before cosmetic work. Keep clear of sagging ceilings and wet electrical equipment.

Worn shingles along a valley
- What You See
- The meeting line between roof slopes carries concentrated runoff.
- The Hidden Hazard Below
- Leaves or worn layers may interrupt drainage. Hidden membrane condition needs professional evaluation.
- The Correct Repair
- Ask a roofer to check drainage, surrounding shingles and the valley lining. Stay off the roof.
