How can I seal my cracked CHIMNEY CROWN from leaking

A leaking chimney can be a persistent problem, particularly in regions subjected to harsh winters. Traditional methods using caulking often prove insufficient.

The typical weak points in a chimney system prone to leaks include the chimney crown and the flashing. The transition between materials is often incorrectly sealed, leading to leaks.

Using the right materials and techniques can extend the life of your chimney considerably. Here’s a detailed approach using fleece and Turbo Poly Seal.

Before starting, ensure that any large debris is removed from the chimney crown. Although a full cleaning isn’t necessary, removing loose particles will enhance adhesion.

• Start by covering any existing cracks and transitions with fleece. The fleece should span from the crown to the bricks, fully covering all problematic joints.
• Once the fleece is in place, apply Turbo over it, ensuring coverage is complete without excessive overlap. This cohesive layer protects the chimney from water infiltration.

Caulking never works. Traditional caulking methods cannot withstand natural chimney movement, leading to cracks and leaks.

By using fleece and Turbo, you achieve flexibility and durability, as the seal can move slightly without cracking.

While this explanation presents a manageable DIY project, expert consultation is advised if your chimney has extensive damage or if you are uncomfortable with roof work.

• Professionals recommend regular inspections to ensure initial DIY efforts remain effective.

Post-repair, consider applying a UV-resistant coating, especially in sunny environments, to protect the Turbo Poly Seal. This step extends the layer's lifespan significantly.

• Use a silver coat aluminum asphalt to protect against UV deterioration.
• Regular inspection and coating every several years are recommended in high sun exposure areas.

Sealing a chimney properly can save significant future repair costs and prevent water damage. Use these techniques to maintain your chimney over time with a careful blend of DIY aptitude and professional guidance when necessary.
