How to Repair Roof Flashing
Why is Roof Flashing Important?
Roof flashing is important because it prevents water from entering your home through roof penetrations. Without proper flashing, water can seep into your home and cause damage to your roof structure, ceiling, walls, and insulation. Additionally, water can lead to mold growth, which can be hazardous to your health.
Types of Roof Flashing
There are several types of roof flashing, including:
- Step flashing: used to flash roof-to-wall intersections
- Drip edge: used to direct water away from the fascia and into gutters
- Vent pipe flashing: used to flash around vent pipes
- Chimney flashing: used to flash around chimneys
How to Repair Roof Flashing
Step 1: Identify the Problem
The first step in repairing roof flashing is to identify the problem. Look for signs of water damage, such as water stains on the ceiling or walls, or water dripping from the roof. Inspect the flashing around roof penetrations, such as chimneys, skylights, and vents, for signs of damage or deterioration.
Step 2: Gather Materials
Before you begin repairing roof flashing, you will need to gather some materials, including:
- Flashing material

Step 3: Remove Old Flashing
Once you have identified the problem and gathered the necessary materials, you can begin removing the old flashing. Use tin snips to cut away the old flashing, being careful not to damage the surrounding shingles or roofing material.
Step 4: Install New Flashing
Once the old flashing has been removed, you can install the new flashing. Cut the new flashing to size using tin snips, and then use roofing cement to secure it in place. Use roofing nails to secure the flashing to the roof, and then seal around the edges with caulk.
Step 5: Inspect and Test
After you have installed the new flashing, inspect it carefully to ensure that it is properly installed and sealed. Test the flashing by spraying it with a hose to simulate rainfall. Check for any signs of water leakage, and make sure that the water is properly directed away from the roof and into gutters.
