Roof Cricket Installation: Preventing Water Intrusion at Chimneys and Roof Intersections

Understanding Roof Crickets: What Are They and Why Do They Matter?
A roof cricket, sometimes called a saddle, is a vital component for directing water away from critical roof intersections, such as the high side of chimneys or where roof planes meet. Without a properly designed cricket, water can pool or flow directly toward vulnerable flashing, increasing the risk of leaks and costly structural damage. Homeowners often overlook this small but essential structure, yet its absence or improper installation is a leading cause of chronic roof leaks.“A well-designed roof cricket is your roof's best defense against persistent water intrusion at intersections and protrusions.”
Key Benefits of Installing a Roof Cricket
- Redirects water away from chimneys, skylights, and vertical wall junctions, minimizing standing water.
- Prevents premature deterioration of flashing and roofing materials in high-risk areas.
- Reduces the likelihood of mold, rot, and interior water damage due to leaks.
- Enhances the overall longevity and performance of your roof system.
Types of Roof Crickets and Material Options
The selection of a roof cricket depends on the intersection's size, roof pitch, and the roofing material in use. Crickets can be built from a variety of materials, each with its own advantages and considerations for durability, compatibility, and cost.| Material | Advantages | Best Use Cases |
| Metal (Galvanized Steel, Copper) | Durable, malleable, excellent water shedding | Steep-slope roofs, high-end or historic homes |
| Asphalt Shingles | Matches main roof, cost-effective | Standard residential roofs with shingle systems |
| Modified Bitumen | Seamless, waterproof, flexible | Low-slope or flat roofs |
Installation Best Practices for Maximum Effectiveness
Proper cricket installation is crucial for performance. Crickets should always be pitched to ensure water flows away from the chimney or intersection and toward the main roof drainage system. The integration with flashing and roofing materials must be seamless to avoid creating new points of vulnerability.- Always match cricket pitch to the main roof or slightly steeper for optimal drainage.
- Use continuous flashing that overlaps both the cricket and the roof surface.
- Seal all seams and fasteners to prevent water infiltration.
- Ensure the cricket extends at least as wide as the chimney or obstruction it serves.
Common Mistakes and How to Avoid Them
Many roof leaks originate from poorly designed or installed crickets. Understanding frequent errors can help homeowners and contractors prevent expensive callbacks and repairs.- Under-sizing the cricket, leading to ineffective water diversion.
- Improper integration with existing flashing systems.
- Neglecting to match roofing material, causing aesthetic and functional issues.
- Failing to maintain or inspect crickets during routine roof checks.
“Attention to detail in roof cricket design and installation pays dividends in roof longevity and leak prevention.”
Maintenance Tips for Long-Term Performance
Regular inspection and maintenance of roof crickets are essential to ensure their ongoing effectiveness. Debris buildup, weathering, and flashing deterioration can compromise the cricket’s ability to channel water away.- Inspect crickets at least twice a year, especially after severe storms.
- Clear debris such as leaves, twigs, and moss that may block water flow.
- Check for signs of rust, loose flashing, or cracked shingles on and around the cricket.
- Promptly repair any damage to maintain a watertight seal.
