Valley leaks

Valleys carry water from two roof planes into one channel, which means they handle more volume than anywhere else on the roof and fail accordingly. Debris packs into the channel, water backs up under the shingle courses on either side, and the leak shows well below where it entered. Repair means opening the courses on both sides to reach the valley metal underneath, which is more work than a surface patch — and the reason a valley leak costs more than a boot.

What the job involves

  • Clearing the valley channel and assessing the metal beneath
  • Opening shingle courses on both sides to inspect the full run
  • Replacing valley metal where it has corroded or been punctured
  • Reinstating the courses with correct overlap and no exposed nails
  • Check of where the valley discharges to confirm it is not backing up

Signs you need it

  • Staining some distance below a valley on the ceiling
  • Visible debris or vegetation packed into the valley channel
  • Rust or pinholes in exposed valley metal

Questions

Why is a valley repair more expensive than other leaks?

Because reaching the valley metal means lifting shingle courses on both slopes and reinstating them correctly afterwards. A patch on top of the valley does not address what is underneath and tends to fail within a season.

Can valleys be cleared as maintenance?

Yes, and it is worth doing annually anywhere with overhanging trees. Most valley failures start as a blockage that backs water up under the courses; clearing it is far cheaper than the repair it prevents.

Describe what you are seeing

Most metro Atlanta leaks trace back to a storm that did not look like it caused damage. The shingles are still there, the roof looks fine from the driveway, and water is getting in anyway. Finding where is the job.
