Roof Cricket: Complete Guide to Cost, Installation, and Benefits
Roofing issues often begin in the most overlooked places behind chimneys, at roof intersections, and around areas where water naturally collects. That’s where roof cricket installation becomes essential. A properly built roof cricket not only protects your home from leaks but also extends the lifespan of your roofing system. For homeowners, contractors, and anyone researching roofing solutions, understanding roof crickets is crucial for preventing structural damage and ensuring long-term roof performance.
In this guide, we break down everything you need to know about roof cricket what it is, why it matters, how much it costs, how to install it, and the challenges and advantages you should consider.
What Is a Roof Cricket?
A roof cricket, also known as a saddle, is a small, peaked structure installed on the high side of a chimney or roof penetration. Its purpose is simple but vital: to divert water away from areas where debris and moisture tend to accumulate.
Primary Functions of a Roof Cricket
- Redirect rainwater away from the chimney or roof penetration
- Prevent water pooling and ice dam formation
- Minimize leaks and moisture damage
- Improve overall roof drainage
Roof crickets are typically built from wood framing and covered with shingles, metal, or waterproof membranes, depending on roof type and local building codes.
Benefits of Installing a Roof Cricket
Installing a roof cricket offers several important benefits:
1. Prevents Chimney Leaks
Chimney leaks are one of the most common roofing problems. A properly built roof cricket channels water to the sides of the chimney instead of letting it pool behind it.
2. Enhances Roof Longevity
Standing water accelerates shingle deterioration. A roof cricket prevents water buildup, helping your roof last longer.
3. Reduces Ice Dams in Winter
In cold climates, melting snow can refreeze behind the chimney. A roof cricket reduces this risk by improving drainage.
4. Improves Home Safety
Water infiltration can cause mold growth and weaken structural elements—problems a roof cricket helps prevent.
5. Required by Building Codes
In many regions, roof crickets are required when chimney width exceeds 30 inches.
How to Install a Roof Cricket (Step-by-Step Guide)
Installing a roof cricket requires precision and should ideally be done by a roofing professional, but here is the general process:
1. Measure the Chimney and Roof Pitch
The height and dimensions of the cricket depend on the roof’s slope and chimney width.
2. Build the Frame
A wooden frame is constructed with a peak centered behind the chimney. The slope should match or exceed the roof pitch for proper water flow.
3. Install Sheathing
Plywood or OSB panels are secured over the frame, forming the cricket’s shape.
4. Apply Waterproof Underlayment
Ice and water shield (or similar membrane) is applied across the cricket and around the chimney base to prevent leaks.
5. Flash the Cricket
Metal flashing is installed along all edges and sealed tightly. This is one of the most important steps.
6. Add Shingles or Metal
The cricket is covered with the same roofing material as the rest of the roof for a seamless look.
7. Inspect for Proper Water Flow
Water testing ensures that the cricket channels water correctly.
How Much Does a Roof Cricket Cost?
The cost of a roof cricket depends on materials, labor, roof pitch, and region.
Average Price Range
Basic roof cricket: $300 – $600
Mid-range, fully flashed cricket: $600 – $1,000
Complex roof cricket with metal finishing: $1,000 – $2,000+
Factors That Affect Cost
- Chimney size
- Roof height and accessibility
- Material (shingle, metal, copper)
- Need for additional repair or flashing replacement
How Long Does It Take to Install a Roof Cricket?
Most installations take 2 to 6 hours, depending on:
- roof pitch
- weather
- complexity of the cricket
- flashing work required
With inspection and finishing, the full process may take half a day to a full day.
Applications of Roof Crickets
Roof crickets are used in multiple roofing situations, including:
✓ Behind Chimneys
- The most common use, required by many building codes.
✓ At Roof Valleys or Intersections
- To redirect water where two roof planes meet.
✓ Around Skylights or Large Vents
- To avoid water pooling near roof penetrations.
✓ On Low-Slope Roofs
- Where drainage is naturally poorer.
Advantages of Roof Cricket Installation
- Excellent leak prevention
- Cost-effective long-term solution
- Customizable to any roof design
- Reduces maintenance requirements
- Helps comply with building codes
Challenges Connected to Roof Crickets
- Improper installation can cause leaks
- Requires skilled labor and precise flashing
- Costs vary significantly based on roof height and pitch
- Not all roofing companies specialize in structural crickets
