How to Spot Roof Leaks Before They Cost You
Look for the subtle clues
Most leaks are not a sudden waterfall. They begin as a damp spot on a ceiling, a faint water line on drywall, or a musty smell in an attic. Catching these early lets you fix the entry point before water travels along joists and damages insulation, framing, and finishes.
Common leak origins
Flashing around penetrations — vents, chimneys, skylights, and plumbing stacks — is the most frequent culprit. Damaged or missing shingles, clogged valley gutters, and deteriorated rubber boots around pipes are close behind. Water can also be pulled in through a soffit or eave if gutters overflow.
What to do first
If you see a stain, document it and check the attic for the source while it is dry. Do not climb onto a steep or wet roof yourself. Temporary patching and tarps can buy time, but only a proper repair stops the cycle of repeat leaks.
Get a professional assessment
Pinpointing a leak reliably takes experience. A professional roofer can trace water paths and fix the root cause rather than the symptom. If you suspect a leak, TNS Contracting provides leak repair and re-roofing services — visit tnscontracting.ca to book a consultation.
