Roof Leak — What to Do Right Now

A roof leak can cause thousands of dollars in damage to ceilings, walls, insulation, and electrical systems. Your first priority is containing the water. Your second priority is calling a licensed roofer. Roof work is inherently dangerous — do not climb onto the roof yourself to investigate.

Key takeaway: Contain the water first: place buckets, poke a hole in any ceiling bulge to drain it, and move valuables. Then call a licensed roofer. Do not get on the roof — wet roofs cause 300+ deaths per year.

What's Happening

Roof leaks originate from damaged or missing shingles, deteriorated flashing (the metal strips around chimneys, vents, and edges), cracked vent boots, clogged gutters causing ice dams, or age-related wear. Water enters through the breach and can travel along rafters and sheathing before dripping through the ceiling — so the drip point inside is often not directly below the leak source on the roof.

⚠ Contain the Water First

Place buckets or containers under active drips
If the ceiling is bulging with water, poke a small hole in the center of the bulge with a screwdriver to drain it into a bucket — this prevents a ceiling collapse
Move furniture and electronics away from the leak area
If water is near electrical fixtures or outlets, turn off the breaker to that area
Take photos of all damage for insurance

Do NOT Get on the Roof

Roof work causes over 300 deaths and 200,000 injuries per year in the US. Wet roofs are extremely slippery. A licensed roofer has the equipment, insurance, and experience to inspect and repair safely. If you can safely access the attic from inside, you can look for daylight coming through the roof sheathing or follow water trails to identify the general leak area — share this info with the roofer.

What to Expect

A roofer will inspect the roof, identify the leak source, and provide a repair estimate. Common repairs include replacing damaged shingles ($150-400), re-sealing flashing ($200-500), or replacing a vent boot ($150-300). If the damage is extensive or the roof is near end of life (20+ years for asphalt shingles), they may recommend a full replacement. Get at least two quotes. Check that the roofer is licensed, insured, and has reviews.
