Installation Guide
Proper installation of the Oatey No-Calk Roof Flashing is essential for a watertight seal. Follow these steps carefully.

Step-by-Step Instructions:
- Preparation: Ensure the roof surface is clear of debris and a waterproof underlayment has been applied.
- Chamfer the Pipe: Before installing the flashing, chamfer the end of the vent pipe to prevent damage to the flashing's collar during installation. This creates a smooth, beveled edge.
- Install Shingles (Bottom-Up): Begin installing shingles in rows, starting from the bottom edge of the roof and working upwards towards the peak. Ensure each row overlaps the one below for proper waterproofing.
- Position the Flashing: Once you reach the pipe penetration, push the flashing down over the chamfered pipe end. Position it flush against the waterproof layer and the installed shingles.
- Secure the Flashing: Secure the flashing to the roof deck using roofing nails. These nails should be concealed under the next few rows of shingles to maintain a leak-free roofing system.
- Complete Shingle Installation: Continue installing shingles in rows until the roof is fully covered, ensuring proper overlap over the flashing base.
- Test for Leaks: After installation, test the flashing by running water over it from a hose for 3 to 5 minutes to ensure there are no leaks.

Maintenance
To ensure the longevity and effectiveness of your Oatey Roof Flashing, periodic maintenance is recommended:
- Regular Inspection: Annually inspect the flashing for any signs of wear, cracking, or damage to the rubber collar or aluminum base.
- Clear Debris: Keep the area around the vent pipe and flashing clear of leaves, branches, and other debris that could trap water or cause damage.
- Check Seal: Ensure the self-sealing collar remains snug around the vent pipe.
Troubleshooting
If you encounter issues with your roof flashing, consider the following:
- Leaks Around Pipe: This often indicates improper installation or damage to the self-sealing collar. Re-check that the collar is properly seated and not torn. Ensure the pipe was chamfered to prevent damage during installation.
- Leaks from Base: Leaks from the base area may suggest that roofing nails were not adequately concealed or that the flashing base is damaged. Inspect the shingles overlapping the flashing for proper placement and integrity.
- Visible Damage: If the aluminum base is bent or cracked, or the rubber collar is severely deteriorated, the flashing may need to be replaced.
