Identifying the Leak

Before you can fix a leak, you need to find it. Here’s how:

1. Look for water stains on your ceiling or walls.
2. Check your attic for damp spots or mold growth.
3. During daylight, use a flashlight to look for holes in the roof decking.

Safety First

Roof repairs can be dangerous. Always:

• Putty knife
• Roofing nails
• Hammer
• Replacement shingles (if needed)
• Caulking gun
• Roofing sealant
• Safety gear (gloves, goggles)

Step-by-Step Repair Process

1. Clean the Area

Wash the roof area around the leak with water and let it dry completely1.

2. Locate the Exact Leak Point

Carefully lift the edges of surrounding shingles to find the source of the leak1.

3. Apply Roofing Cement

Use a putty knife to apply roofing cement under loose shingles and press them down3.

4. Replace Damaged Shingles

If shingles are severely damaged:

1. Remove the old shingle by lifting its edges and pulling out the nails.
2. Slide the new shingle into place.
3. Secure with roofing nails.
4. Apply sealant over the nail heads4.

5. Repair Flashing

For leaks around vents or chimneys:

1. Remove old caulk or roofing cement.
2. Apply new silicone caulk or roofing sealant around the base of the vent or chimney7.

6. Fix Small Holes

For tiny holes:

1. Clean the area with a wire brush.
2. Apply roofing sealant directly over the hole.
3. Cover with a small piece of flashing or shingle3.

When to Call a Professional
