Roof leaks can cause water damage inside your home. A quick temporary fix buys time until you get professional help. This guide covers safe ways to stop leaks short-term. It includes steps, materials, and tips to keep your home dry.
Signs Your Roof Has a Leak
Water spots on ceilings or walls often show a leak. Check for damp insulation in the attic. Look for missing shingles or cracks outside. Stains on roof rafters point to the problem area. Act fast to avoid mold or structural issues. If you spot these signs after a storm, start with a temporary repair.
Safety First Before You Start
Work on your roof only if it is safe. Wear sturdy shoes with good grip. Have someone spot you from below. Avoid wet or steep roofs. Use a stable ladder. If the roof is high or damaged, stay off it and fix from inside. Call a pro if you feel unsure.
Tools and Materials You’ll Need
Gather these items from a hardware store. They cost under $50 for most fixes.
- Heavy-duty tarp or plastic sheeting
- Roofing tape or silicone caulk
- Roofing cement or patching compound
- Duct tape
- Nails, hammer, or caulk gun
- Ladder
- Gloves and flashlight

How to Locate the Leak
Finding the source stops water flow. Go to the attic during rain if safe. Shine a flashlight on rafters for drips. Mark the spot with tape. From outside, check for damaged shingles or holes. Dry weather? Spray water on the roof with a hose and watch inside for drips. This method works well for hidden leaks.
Method 1: Cover with a Tarp or Plastic Sheeting
Tarps block rain fast. This works for large areas.
- Climb the roof carefully.
- Unfold the tarp over the leak. Make it 4 feet wider on all sides.
- Smooth it flat to avoid puddles.
- Secure edges with nails or boards. Use duct tape for extra hold.
- Weigh down corners with bricks if needed.
This lasts through a few storms. Replace if wind tears it.

Method 2: Seal with Roofing Tape or Caulk
Use this for small cracks or gaps. It seals without much climbing.
- Clean the area dry with a cloth.
- Apply tape over the crack. Press firm for a tight seal.
- For caulk, cut the tube tip. Squeeze into the gap.
- Smooth with a finger or tool. Let dry for an hour.
Tape works from the attic side too. Caulk handles minor holes well. Buy quality tape rated for roofs. It holds in rain.
Method 3: Patch with Roofing Cement
Cement fills holes like a plug. Good for punctures from branches.
- Mix cement per package. It sets like putty.
- Spread over the hole with a putty knife.
- Press in place. Add a layer of tar paper if you have it.
- Let cure for 24 hours.
This method plugs from outside. Repeat if water keeps coming.

Fixes from Inside the Attic
Skip the roof if it’s risky. Work from below.
- Find the drip spot in the attic.
- Place a bucket under it to catch water.
- Apply roofing tape to the underside of the roof deck.
- For bigger leaks, use a plastic sheet taped up.
This catches water and slows flow. Ventilate the attic to dry it out.
Common question: Can you fix a roof leak from inside? Yes, for short-term relief.
When to Call a Professional
Temporary fixes last weeks, not years. Call a roofer if:
- Leak persists after your patch.
- You see large damage or sagging ceiling.
- Water enters electrical areas.
- Roof is over 20 years old.
Pros find hidden issues. Get quotes from local roofers. For flat roofs, special methods apply like reinforced sheeting.
