Trace your roof leak back to the real source
Ceiling stains rarely sit directly under the leak. Answer three questions and I'll narrow down the likely cause — and tell you whether it's actually a roof problem at all.
Symptoms
What are you seeing?
Likely cause 1
Underlayment failure or nail pop
On pitched roofs, mid-field leaks are often nail pops, cracked shingles from hail, or underlayment that's degraded under an aging tile roof.
Do this next:An inspection with attic access lets us trace the wet path uphill to the actual entry point — it's rarely directly above the stain.
Why this matters
Most 'roof leaks' aren't the roof field
After 20+ years on NM roofs, I can tell you: 8 out of 10 leaks are flashing, boots, or vents — not the shingles or membrane. A contractor who leads with 'you need a new roof' before finding the actual leak is guessing with your money.
