Preparation and Safety Guidelines
- Books Turbo Poly sealant
- Painter's tape (optional)
- Working at heights is dangerous. Use proper safety equipment like a harness and fall protection system, especially on flat roofs. If uncomfortable, hire a professional.
- Always turn off any gas appliances before working near the chimney. Gas leaks are serious and potentially fatal.
- Wear appropriate safety gear, including gloves, eye protection, and sturdy work boots to prevent injury from sharp materials or falling debris.
Step-by-Step Instructions
Locate the Leak Source
- Identify the leak source. Often, leaks appearing near skylights or lower on the roof actually originate from the chimney flashing above.
Inspect Chimney Condition
- Inspect the chimney for cracks or damaged areas. These are common entry points for water.
Inspect Chimney Condition Examine Chimney Caulking
- Check the caulking around the chimney base. Even if the flashing itself seems intact, loose or deteriorated caulking allows water to seep behind it.

Prepare for Repair Apply Sealant
- Apply Books Turbo Poly sealant to the problem areas. This is a superior alternative to caulking because it is more durable and lasting.
