What to Do If Your Roof Starts Leaking During Heavy Rain in Pasadena

A roof leak during heavy rain is one of the most stressful things a Pasadena homeowner can face. You’re watching water drip through your ceiling at 11pm with no idea what to do next. This guide gives you the exact steps to take — right now, before the roofer arrives.

Step 1: Contain the Water Immediately

Place buckets, towels, or trash cans under every drip. Move furniture and electronics away from wet areas. Water that sits on wood floors causes damage that can cost thousands — far more than the roof repair itself.

If the ceiling is bulging, it may be holding pooled water. Carefully poke a small hole in the center of the bulge with a screwdriver to let it drain in a controlled way — otherwise it can collapse suddenly.

Step 2: Document Everything (Before You Clean Up)

This is critical — especially if you plan to file an insurance claim. Take dated photos and video of:

• The ceiling drip location
• Any visible staining or discoloration
• Damage to flooring, furniture, or walls
• Any visible exterior roof damage if safely visible

California’s 14-day rule: If your leak was caused by a storm, Santa Ana winds, or another sudden event, you must report it to your insurance company within 14 days. Don’t wait until the repair is done.

Step 3: Check Your Attic (If Safe)

The drip location on your ceiling is almost never directly below the actual entry point. Water travels along rafters, insulation, and sheathing before it drips. If it’s safe to access your attic, look for wet insulation or water stains on the decking — this will help us find the source much faster when we arrive.

Step 4: Don’t Try to Fix It Yourself in the Rain

Walking on a wet roof is extremely dangerous. Temporary caulking or patches applied in the rain almost always fail within one storm cycle and can make the actual repair more expensive. Wait for a professional — it’s not worth the risk.

Step 5: Call for Emergency Service

When you call us, tell us:

• Where the drip is (which room, ceiling location)
• Whether water is coming in actively or has stopped
• If you saw any visible damage (displaced tiles, missing shingles)

We’ll tell you whether you need emergency tarping tonight or whether we can safely wait until morning. Emergency tarping stops water entry immediately while we schedule the permanent repair.

The Most Common Causes of Roof Leaks During Rain in Pasadena

After responding to hundreds of emergency calls across Pasadena, these are what we find most often:

• Failed chimney flashing — The #1 cause. Original flashing fails at 20–30 years. Missing or separated cricket flashing lets water pool.
• Underlayment failure — Especially in clay tile homes. The tile looks fine but the felt beneath has deteriorated.
• Valley leaks — Where two roof planes meet, flashing wears out or debris dams up.
• Pipe boot failures — Rubber boots around plumbing vents crack from UV exposure.
• Gutter backup — Clogged gutters cause water to back up under shingles during heavy rain.

What Happens When We Arrive

We inspect the attic first, then the exterior. We photograph everything. We tell you exactly what failed and what it will cost to fix it — before we start. If you need emergency tarping, we do that immediately. Permanent repair is scheduled as soon as weather allows.
