Roof Cricket Installation

Your roof may be missing a critical component called a cricket.

Roof crickets are one of the most important but most overlooked features in roofing. When they are missing or installed incorrectly, water can collect in one spot and eventually find its way into your home.

At Mr. GoodRoof, we provide roof cricket installation in Nashville to properly manage water flow and protect one of the most vulnerable areas of your roof.

A roof cricket is a small, peaked structure installed on the uphill side of a chimney or large roof penetration.

Its purpose is to:

Without a cricket, water hits the back of the chimney and has nowhere to go, which creates a high-risk leak area.

From what we see in the field, chimney leaks are one of the most common roofing problems.

In many cases, the issue is not just flashing. It is water buildup behind the chimney.

Without a cricket, this can lead to:

A properly installed cricket eliminates this problem by keeping water moving.

In many cases, building codes require a cricket when a chimney reaches a certain width.

Even when not required, we often recommend crickets because they significantly improve long-term performance.

Homes that typically benefit from crickets include:

From our experience, adding a cricket is one of the best ways to prevent recurring chimney leaks.

A cricket creates a small ridge that splits the flow of water.

Instead of water hitting the chimney and stopping, the cricket diverts it to both sides, allowing it to continue down the roof naturally.

This reduces pressure on flashing and prevents pooling in vulnerable areas.

A cricket is not a replacement for flashing. It works together with it.

Flashing seals the transition between the roof and the chimney, while the cricket manages how water flows around that area.

When both are installed correctly, they provide strong, long-term protection against leaks.

If water is not flowing properly around your chimney, a cricket may be the missing piece.

We see this all the time across Nashville homes.

Many contractors skip installing crickets because:

But skipping this step often leads to problems later.

We do not just look at the flashing. We look at how water is moving across your roof.

From our experience, many chimney leaks are caused by poor water management, not just material failure.
