Roof leak? Here’s what to do before calling a contractor

A roof leak is one of those problems that always seems to happen at the worst time, during a storm, at night, or right when you’re heading out the door. While your first instinct may be to call a contractor immediately (and eventually you should), there are a few smart steps you can take first. These early actions can prevent additional damage, help you assess the situation clearly, and ensure that when you do call someone, you’re ready to have a productive conversation.

Before reaching out to a roof installation or repair expert, here’s what you should do.

Step 1: Safely contain the water

If water is dripping through the ceiling, your first job is to minimize interior damage. Place a bucket, large pot, or plastic bin under the leak to catch water. You can also put towels or rags around the base to absorb splashes and prevent damage to flooring or furniture.

If the water is pooling in the ceiling and hasn’t broken through yet, you might notice a bulge or discoloration. In that case, carefully puncture the bubble with a screwdriver or small nail to allow the water to drain in a controlled way. Otherwise, it could burst on its own, creating a much bigger mess.

Step 2: Move valuables out of harm’s way

It might sound obvious, but in the moment, many homeowners forget to protect what’s under the leak. If the water is near electronics, documents, bedding, or furniture, move those items immediately.

For items that can’t be moved (like a heavy sectional sofa), cover them with plastic tarps or trash bags. The goal is to limit the damage the water can cause while you wait for help.

Step 3: Check the attic, if it’s safe

If you can safely access your attic, it’s a good idea to take a look while the leak is happening. Bring a flashlight and look for:

• Wet insulation
• Dripping water or wet wood
• Moldy or damp smells
• Water trails on roof decking or rafters

This can help you trace the leak back to its source, which is not always directly above the drip. Water often travels along beams before it shows up inside. Having this information ready when you contact a contractor will make your repair more accurate and efficient.

If you notice signs of long-term damage, your contractor may recommend a partial roof replacement to fix the underlying issues.

Step 4: Identify the possible source

Outside of the attic, walk around your property (safely) and look for visible damage. Some common causes of roof leaks include:

• Missing or cracked shingles
• Damaged flashing around vents or chimneys
• Clogged or overflowing gutters
• Broken skylight seals
• Debris buildup in roof valleys
  
  

If a recent storm just passed through, high winds could have lifted shingles or loosened nails. While it’s best not to climb onto the roof yourself, documenting what you can see from the ground or inside helps give your roof installation contractor a head start.

Step 5: Document everything

Take clear photos of any visible damage, inside and out. Include:

• Water stains on ceilings or walls
• Buckling or bubbling paint
• Wet spots or pooling water
• Exterior signs of roofing damage

These photos are helpful for your contractor and insurance claims. Many policies cover sudden roof damage, especially after wind, hail, or storm events. A contractor may also ask to see your documentation before scheduling a full inspection or estimate.

Step 6: Check your records and warranty

Do you know when your current roof was installed? If it’s under 10–15 years old, you may still be covered under a materials or labor warranty, depending on the contractor and product used. Look for:

• Paperwork from your last installation
• Manufacturer warranties on shingles or membrane
• Notes from any prior repairs

This can influence how your contractor approaches the repair. In some cases, it may also factor into your decision about roof replacement versus repair.

Step 7: Avoid temporary DIY fixes

It might be tempting to throw some roof sealant or patching tape on the problem, especially if the leak is slow. But DIY repairs often make things worse, masking the damage, voiding warranties, or hiding water intrusion that leads to mold.

Instead, focus on short-term protection inside the home while you wait for professional help. A skilled contractor can properly inspect the area, identify hidden water damage, and recommend the most effective repair.
