This design not only enhances the functionality of the roof but also adds a visually appealing element, creating a seamless transition between the structures. The purpose of the dual slope cricket is to create a smooth flow of water down both sides, preventing water buildup and potential leaks. The design is effective in directing water away from the vulnerable area, ensuring proper drainage and minimizing the risk of moisture damage.
How to Insulate Walls Without Removing the Drywall
To finish the installation, you´ll need to add flashing and shingles to the cricket. Flashing is a thin metal sheet that helps seal the cricket´s seams and edges, preventing water from seeping in. Shingles, on the other hand, cover the cricket´s surface, providing aditional protection and a consistent appearance with the rest of the roof. Install the flashing first, followed by the shingles, making sure to overlap the materials correctly to ensure proper water drainage.
Changes in the Roofing Industry and What They Mean for Homeowners:
Not all properties require a cricket; however, they are mandated for chimneys over 30 inches wide. Most properties can benefit from a roof cricket whether or not their chimney meets the requirements. The chimney cricket is an important feature to ensure water will properly flow around the chimney instead of being trapped behind it causing potential leaks. Having proper understanding of when a chimney cricket needs to be provided is of utmost importance to any code professional. Crickets are triangular structures designed to divert water away from areas of a roof that may collect water. In residential roofing, we tend to think of chimneys as the prime example – chimney cricket.

If you’re getting your roof replaced through homeowners insurance and have a code upgrade coverage policy, your insurance company will pay to have your cricket installed. Using the measurements obtained, draw a template of the cricket on a sheet of plywood or other suitable material. Use a circular saw, miter saw, or metal shears, as appropriate for the material you´re working with.

Remember, you need a cricket behind your chimney to allow water to continue flowing properly down your roof. While this is extremely important, installing crickets is actually a building code. On a low-slope roof system, crickets are built using sloped rigid insulation and then covered with the membrane roofing system. Crickets for low-sloped roofs are built in a triangular or diamond-shaped pattern and have a slope double that of the roof for a net-positive backslope.
Roof Cricket Maintenance and Inspection
The cricket would be framed out of wood, sheeted, and then shingled (being sure to flash the chimney with metal). Place the frame on top of the roof, aligning it with the chimney or wall. Secure the frame by fastening it every 12 inches along the edges and every 6 inches on the interior bracing. The entire saddle structure must be covered with ice and water protector. The 2015 International Residential Code has guidelines about how high a cricket should extend up the chimney based on the slope of the roof.

If you’re installing closed valleys, it may make more sense for you to install shingles as well as flashing onto the cricket. A clay tile roof cricket design involves creating a sloped structure on the high side of the chimney or other roof element to divert water away. When dealing with larger chimneys, an extended cricket design proves to be highly beneficial. This type of roof cricket goes beyond the standard size and extends further along the roofline to provide enhanced protection and proper water diversion. Grass-covered rooftop cricket design adds a touch of natural beauty to your roof while serving its functional purpose. Rather than opting for traditional roofing materials, this innovative approach incorporates a layer of grass atop the cricket structure.
Roof Cricket Between Multiple Structures
The construction process can vary depending on the complexity of the design, but it typically takes several hours to complete. Another mistake is failing to align the roof cricket properly with the adjacent roof sections or walls. Improper alignment can result in gaps or overlapping, which can compromise the functionality and aesthetics of the cricket.

The modified saddle-style cricket is a popular design choice for addressing water accumulation on the roof behind a chimney or vertical wall. Unlike a traditional saddle-style cricket that forms a symmetrical inverted V shape, the modified version is customized to fit the specific roof geometry and improve water diversion. By adjusting the angles and dimensions of the cricket, it ensures efficient water flow, preventing any pooling or leakage issues. This innovative design provides enhanced protection against water damage, making it a practical and visually appealing option for roof crickets.
Traditional roof crickets are custom-built on-site using wood or metal framing materials, such as plywood, dimensional lumber, or metal flashing. The process starts with measuring the roof slope and the size of the roof projection, such as a chimney or skylight, to determine the necessary dimensions for the cricket. Roof cricket design is an essential aspect of any well-built roofing system. It plays a crucial role in diverting water away from vulnerable areas, preventing leaks, and ensuring the longevity of your roof. Whether you’re a homeowner planning a new roof installation or a roofing professional looking to enhance your knowledge, understanding the importance of roof cricket design is paramount.
In this article, we´ll explore everything you need to know about roof crickets, from their importance to the individual types and how to install them properly. A well-designed cricket/saddle is crucial for effective roof assembly design. By following these guidelines, architects can optimize their roof systems, minimize water-related issues, and enhance the overall performance of their buildings. Remember to tailor the design to the specific requirements of the roof system, materials, and local climate conditions. With careful planning and attention to detail, you can ensure a robust and reliable roof structure for your architectural projects.
