Mastering the Art of Water Damage Prevention: Why Roof Crickets Are Your Home’s Unsung Heroes
What Are Roof Crickets and How Do They Work?
Roof crickets, also known as chimney crickets, are small ridge-like structures built on sloped roofs to divert water away from chimneys and other roof penetrations. They channel water around the penetration and off the roof, typically on the uphill side of the penetration. In addition to chimneys, roof crickets play an important role in preventing water damage around skylights, vents, and air conditioning units.
The Benefits of Proper Roof Cricket Installation
Firstly, the primary purpose of a roof cricket is to prevent water from pooling around the base of the penetration. Pooling water can lead to leaks and other types of water damage to the roof and interior of the building. Therefore, a properly designed and installed cricket is crucial for roofs with a high pitch or steep slope, as well as areas with heavy rainfall or snow.
In addition to preventing water damage, roof crickets can improve the overall efficiency of the roof. By channeling water away from penetrations, the cricket reduces the amount of water that comes into contact with the roofing material. This, in turn, reduces the risk of mold and mildew growth and extends the lifespan of the roof.
Tips for Proper Roof Cricket Installation
To ensure that your roof cricket effectively diverts water away from penetrations, follow these tips:
- First, consult with a professional roofing contractor to determine the appropriate size and placement of the cricket for your roofing system.
- Secondly, use corrosion-resistant metals or pressure-treated wood to ensure the longevity of the cricket.
- Thirdly, properly install and flash the cricket to prevent leaks and water damage.
- Lastly, regularly inspect and maintain the cricket to ensure that it continues to function properly and prevent water damage.
By following these tips, you can ensure that your roofing system includes a properly designed and installed roof cricket that protects your roof and building from water damage.
Building Codes for Roof Crickets
Building codes pertaining to crickets on roofs can vary depending on the location and type of building. However, here are some general guidelines that may apply:
International Building Code (IBC)
The IBC requires crickets on roofs with a width of 30 feet or more and a slope greater than 4:12 (18.4 degrees). The cricket must be at least as wide as the penetration and have a slope of at least 3:12 (14.1 degrees).
International Residential Code (IRC)
The IRC requires crickets on residential roofs with a width of 24 feet or more and a slope greater than 3:12 (14.1 degrees). The cricket must be at least as wide as the penetration and have a slope of at least 4:12 (18.4 degrees).
National Roofing Contractors Association (NRCA)
The NRCA recommends the use of crickets on roofs with a width of 12 feet or more and a slope greater
