Why Roof Leaks Happen
Roof leaks can result from many small issues that add up over time. Common causes include:
- Damaged shingles or flashing
- Cracked vent boots or chimneys
- Clogged gutters causing water backup
- Ice dams in colder regions
- Poor attic ventilation
- Aging roofing materials
A small puncture allows water to wander silently into your roof. From there, it moves along rafters and insulation, leaving traces as ceiling stains or damp attic corners. Find the culprit first! Fixing from the inside without knowing the source? That’s temporary at best.
Step 1: Locate the Source of the Leak
Don’t start fixing yet, trace where that leak really starts first.
How to Inspect from the Inside:
- Enter your attic with a flashlight during or soon after rain.
- Check for dark marks, moist wood, or dripping water.
- Trace the wet path uphill toward the roof decking. Water goes down, so your leak probably begins higher than what you see.
- Grab some chalk or tape and mark the area to remember it later.
If no water’s dripping, just wait for rain or spray your roof while someone checks inside.
Step 2: Contain the Water Damage
After locating the leak, take steps to contain the spread immediately.
- Position a bucket or container beneath the dripping area.
- Cover insulation and flooring with a towel or tarp.
- When water forms a bulge in drywall, pierce the lowest section carefully to release pressure.
Though it seems unsafe, this step prevents collapse and regulates water flow.
Step 3: Create a Temporary Patch
In this step of how to repair a leaking roof from the inside, apply a durable seal quickly.
You’ll Need:
- Roofing tar or patch sealant
- A putty knife
- Plywood or scrap shingle
- Flashlight
- Ladder and gloves
Steps:
- Use a towel or fan to dry the spot completely.
- Add a thick coat of roofing tar or rubber sealant on the leak.
- Place a bit of plywood or a shingle right over the tar.
- Add another coat of tar to seal the patch edges.
This interim roof sealing method functions for limited leaks until external inspection by a roofing technician.
Step 4: Inspect Attic Insulation and Roof Decking
After patching, it’s time to assess hidden water damage.
Check for:
- Wet or sagging insulation (replace if soaked)
- Soft or dark patches on roof boards
- A musty smell showing mold or mildew
Take out any wet insulation so it dries quicker. Constant moisture brings wood rot and higher bills since wet insulation can’t work right. South Star Roofing suggests keeping attic air below 50% humidity and airflow steady to avoid future leaks.
Step 5: Monitor and Schedule Professional Inspection
Even if your patch worked, don’t think the problem is gone. A roofing expert should look at your home’s outside once the weather clears. They’ll check for:
- Damaged shingles or flashing.
- Cracked vent boots
- Structural issues near chimneys or skylights

Why Fixing from the Inside Is Only Temporary
Homeowners ask, “Can I stop a leaking roof from the inside forever?” Not entirely, so acting quickly with temporary fixes is key to minimizing damage.
Repairing from the inside only stops the symptom, not the cause. Water enters from the outside layer, so internal patches are a temporary measure to prevent worsening damage until professionals arrive.
Experts at South Star Roofing advise scheduling an exterior roof repair within days of your interior patch to complement how to repair a leaking roof from the inside.
