What is a Roof Cricket?

A roof cricket is a double triangle structure built behind a chimney to properly divert water around it. It prevents water from hitting the flat wall of the chimney, which can lead to leaks and water damage. Without a cricket, water can pool behind the chimney, causing further damage to the roof and potentially requiring costly repairs. Roof crickets are an essential component of a well-functioning roofing system, ensuring proper water flow and prolonging the lifespan of the roof.

When it comes to safeguarding your home and protecting it from water damage, a cricket roof plays a vital role. This specialized structure is designed to divert water away from a chimney, preventing potential leaks and costly repairs down the line. Without a cricket roof, water can accumulate behind the chimney, seeping into the roofing material and causing significant damage over time.

The primary purpose of a cricket roof is to redirect water around the chimney, ensuring that it flows away from the flat wall. By creating a double triangle structure, the cricket roof effectively guides water off the roof and helps maintain a dry and watertight environment. This is particularly important for chimneys that have a wide width, as building codes often require the installation of a cricket roof to comply with regulations.

By diverting water away from the chimney, a cricket roof prevents water from pooling and causing potential structural damage to the roof. It also helps protect against leaks, moisture intrusion, and rot that can result from prolonged exposure to water. In addition to its functional benefits, a cricket roof can enhance the aesthetic appeal of your home and contribute to its overall value.

Roof crickets are typically constructed using durable materials such as wood and are covered with metal flashing or asphalt shingles to ensure longevity and weather resistance. The size and design of a cricket roof depend on several factors, including the roof slope, chimney dimensions, and local building codes.

Whether you’re building a new home, replacing your roof, or upgrading your existing chimney, it’s important to consider the installation of a roof cricket. By incorporating this essential component into your roofing system, you can protect your home from water damage, extend the lifespan of your roof, and maintain a safe and secure living environment.

When it comes to protecting your home, a roof cricket is a critical element that should not be overlooked. With its ability to divert water away from chimneys and prevent potential damage, a well-designed and properly installed cricket roof is an investment in the long-term health and durability of your roofing system.

Types of Roof Crickets

Roof crickets are available in various designs to cater to the specific needs of different roofs. Let’s explore the different types of roof crickets based on the roof slope:

1. Steep-Sloped Roofs

On roofs with steep slopes, crickets are typically constructed as wood-framed structures covered with metal or roofing materials like asphalt shingles. These crickets are designed in a half-diamond pattern and serve as a diversion for water around chimneys, skylights, and other roof protrusions. They play a crucial role in redirecting water, ensuring it flows away from these vulnerable areas and avoiding potential leaks and water damage.

2. Low-Sloped Roofs

For roofs with low slopes, crickets are built using sloped rigid insulation and covered with a membrane roofing system. These crickets take on a triangular or diamond-shaped pattern, facilitating proper water flow to drains and scuppers. By redirecting water away from the vulnerable areas, these crickets effectively prevent water accumulation and potential damage, ensuring the longevity of the roofing system.

Roof crickets are an essential component of a well-designed roofing system. Their strategic placement and design ensure efficient water diversion, preventing leaks and water damage to the roof and other parts of the structure. Whether it’s a steep-sloped or low-sloped roof, the appropriate type of cricket should be selected to guarantee optimal performance and protection.
