Definition of a Roof Cricket

A roof cricket, also known as a saddle or diverter, is a small triangular structure that is constructed on a roof to divert water away from the valley created by the intersection of two roof slopes or where a roof slope meets a vertical wall.

The term “cricket” is derived from its shape, resembling a cricket bat or wicket used in the sport of cricket. Roof crickets are typically made of the same materials as the rest of the roof, such as shingles, metal, or tiles, ensuring continuity in the roof’s appearance.

Roof crickets are commonly used in areas with heavy rainfall or snow to prevent water from pooling in the valleys and causing potential water damage. By redirecting the water, a roof cricket helps to maintain the structural integrity of the roof and prolong its lifespan.

Roof crickets can be found on various types of roofs, including gable roofs, hip roofs, and mansard roofs. They are typically installed on the uphill side of a chimney, skylight, dormer, or any other vertical structure that intersects with the roof.

Overall, the purpose of a roof cricket is to ensure proper water drainage and prevent water from infiltrating the vulnerable areas of the roof. By diverting the water away from the valleys, a roof cricket helps to protect the roof from leaks, decay, and other moisture-related issues.

Purpose of a Roof Cricket

The primary purpose of a roof cricket is to divert water away from the valley created by the intersection of two roof slopes or where a roof slope meets a vertical wall. This is crucial for maintaining the integrity of the roof and preventing water damage. Here are the key purposes of having a roof cricket:

1. Water Diversion: One of the main functions of a roof cricket is to redirect water away from the valley. When water flows down a roof slope, it naturally tends to accumulate in the valleys, especially during heavy rainfall or snowmelt. By having a roof cricket in place, the water is directed around the valley, preventing pooling and potential water damage to the roof.
2. Preventing Leaks: Valleys are vulnerable areas on a roof where water can easily seep through and cause leaks. A roof cricket acts as a barrier, preventing water from entering the valleys and infiltrating the underlying structure of the roof. This helps to maintain a watertight roof and protect the interior of the building from water damage.
3. Snow Management: In areas with heavy snowfall, roof crickets are especially important. Snow tends to accumulate in valleys and can create a significant amount of weight on the roof. By diverting the snow around the valleys, roof crickets help to distribute the weight evenly and reduce the risk of structural damage caused by snow load.
4. Improved Roof Drainage: The presence of a roof cricket improves overall roof drainage by directing water away from the valleys and towards the gutters or downspouts. This helps to prevent water from overflowing the gutters and causing damage to the roof edge or the foundation of the building.
5. Enhanced Roof Aesthetics: Roof crickets also play a role in enhancing the visual appeal of a roof. By adding a roof cricket at the intersection of roof slopes or where a roof meets a vertical wall, the roof is given a more seamless and uniform appearance. This can improve the overall curb appeal of the building.

In summary, a roof cricket serves multiple purposes, including water diversion, leak prevention, snow management, improved roof drainage, and enhanced roof aesthetics. By fulfilling these functions, roof crickets contribute to the longevity and performance of a roof, protecting it from potential damage caused by water accumulation and improving its overall functionality.
