Leaks that appear after a full replacement
A new roof that leaks usually points at how it was installed rather than the materials themselves. Flashing around chimneys, valleys, and vents is where water most often gets in, and it's also the part most likely to be rushed.
- What proves it
- Photographs taken inside the attic during or just after rain, showing where water enters, plus the contract's flashing line. Flashing is itemized on most roofing contracts, so what was paid for is written down.
- What the business usually says
- The usual answer is that the leak is somewhere else, or that the roof is fine and the problem is the chimney. Both are testable: an independent roofer's written inspection names the entry point, and that report is the document that ends the conversation.
