What is a Cricket in Construction?

Introduction

In the construction industry, a cricket is a small, raised structure built on a roof to divert water away from obstacles such as chimneys, vents, or skylights. Crickets are essential for preventing water accumulation and ensuring proper drainage, especially in areas with heavy rainfall or snow. This article will explore the purpose, design, and importance of crickets in roof construction.

Purpose of Crickets in Roof Construction

Preventing Water Accumulation

The primary function of a cricket is to prevent water from pooling around roof penetrations or obstacles. By directing water flow, crickets reduce the risk of leaks and water damage.

Enhancing Roof Drainage

Crickets are designed to improve the overall drainage of a roof by channeling water towards gutters or drainage systems, ensuring that the roof remains dry and free from standing water.

Design and Construction of Crickets

Slope and Shape

Crickets are typically sloped to match the pitch of the roof and are often triangular or half-dome in shape to effectively redirect water.

Materials

Cricket construction materials should be compatible with the existing roof and waterproofing systems. Common materials include metal, membrane roofing, or built-up roofing.

Integration with Roofing Systems

Proper integration with the roofing system is crucial to ensure the effectiveness of a cricket. This includes ensuring a watertight seal around the base of the cricket and any roof penetrations.

Importance of Crickets in Construction

Preventing Roof Leaks

By diverting water away from vulnerable areas, crickets play a vital role in preventing roof leaks and extending the lifespan of roofing materials.

Protecting Structural Integrity

By preventing water accumulation, crickets help protect the structural integrity of the roof and the building as a whole.

Compliance with Building Codes

In many regions, building codes require the installation of crickets on roofs with certain pitches or around specific roof penetrations to ensure proper water drainage.

Conclusion

A cricket in construction is a critical component of roof design, particularly for buildings with complex roof structures or in areas prone to heavy precipitation. By diverting water away from obstacles and enhancing roof drainage, crickets help prevent leaks, protect the structural integrity of buildings, and ensure compliance with building codes. Proper design, materials, and integration with roofing systems are essential for the effective performance of crickets in roof construction.
