Introduction
If you look closely at different roofs around Northwest Arkansas, you may notice a small peaked structure behind some chimneys. It can look like a miniature roof built into the larger roof surface. That feature is commonly called a roof cricket.
Roof crickets are easy to overlook, but they serve an important purpose. Chimneys and other large roof penetrations interrupt the natural path that rainwater follows down a roof. Without an effective way to redirect that water, moisture and debris may collect behind the obstruction.
At FES Roofing, we believe understanding smaller roofing components can help homeowners recognize how the entire system works together. Here is what a roof cricket does, why drainage around chimneys matters, and when your home may benefit from having one.
What Is a Roof Cricket?
A roof cricket is a raised structure installed on the uphill side of a chimney or another large roof obstruction. It is sometimes called a saddle because of its shape.
Instead of allowing rainwater to travel directly toward the back of the chimney, the cricket divides the flow and sends water toward either side.
How a Roof Cricket Works
Imagine rainwater moving down the slope of your roof. When that water reaches a chimney, the chimney acts like a barrier.
A cricket creates two smaller slopes behind that barrier. Water reaches the cricket and is redirected around the chimney rather than collecting directly behind it.
The cricket becomes part of the roof’s overall drainage system, working with shingles and flashing to help move water toward the roof edges.
Why Can Water Collect Behind a Chimney?
A normal roof slope encourages water to move downward. Chimneys interrupt that movement because they extend vertically through the roof.
The Uphill Side Creates an Obstruction
The back of the chimney faces water coming down the roof.
Without proper drainage, this area can experience greater water exposure than an uninterrupted section of roof. Leaves, twigs, pine needles, and other debris can also accumulate there.
When debris collects, it may slow drainage further and hold moisture against the roofing materials.
Flashing Has an Important Job
Chimneys typically require flashing where they meet the roof. Flashing helps protect the transition between the chimney and roofing materials.
Homeowners who want to understand this component in more detail can read about what role flashing plays in preventing roof leaks.
A roof cricket does not replace chimney flashing. Instead, the two components work together. The cricket manages water flow while properly installed flashing helps protect the joints around the chimney.
What Problems Can Develop Without Proper Drainage?
A roof without a cricket is not automatically defective. Whether one is appropriate depends on the roof and chimney design.
However, poor drainage behind a large chimney can create conditions that deserve attention.
Standing or Slow-Moving Water
Water that cannot move efficiently around an obstruction remains in contact with roofing materials longer.
Roofing systems are designed to shed water. Areas where water repeatedly slows down or collects can experience different wear patterns than the surrounding roof.
Debris Accumulation
Leaves and other organic material may become trapped behind a chimney.
When debris stays wet after rainfall, it can hold moisture against shingles and flashing. It can also make it more difficult for homeowners to notice changes in the materials underneath.
Increased Stress Around Flashing
Repeated water exposure can place additional demands on the flashing system around a chimney.
If flashing is already loose, damaged, or deteriorating, water may find a path underneath surrounding materials. Understanding common roof leaks and what causes them can help homeowners recognize why roof penetrations deserve particular attention.
Does Every Chimney Need a Roof Cricket?
No. The presence or absence of a cricket alone does not tell you whether a roof has been designed incorrectly.
Several factors determine whether a cricket is needed or beneficial.
Chimney Size
The width of the chimney is an important consideration.
A wider chimney creates a larger obstruction to water moving down the roof. As the width increases, redirecting water around the chimney becomes increasingly important.
Building requirements can also affect when a cricket or saddle is required, so the appropriate configuration should be evaluated for the specific home and roofing project.
Roof Pitch
The slope of the roof influences how quickly water approaches and moves around the chimney.
A professional can evaluate how the chimney, slope, flashing, and surrounding roofing materials interact rather than considering any one component by itself.
Location on the Roof
Where the chimney sits can also affect drainage.
A chimney located in an area that receives substantial runoff from the roof above it may experience different water conditions than one located closer to a ridge.
This is one reason a roof inspection can be useful when homeowners have concerns about drainage around a chimney.
What Is a Roof Cricket Made Of?
A cricket is more than a decorative feature placed behind a chimney. It needs to function as part of the roofing system.
Structural Base
The cricket begins with a properly shaped structural surface that creates the slopes needed to redirect water.
Its exact construction depends on the size of the chimney, roof design, and existing structure.
Underlayment and Roofing Materials
The cricket is typically integrated with appropriate underlayment and roofing materials so water can move smoothly across it.
On an asphalt shingle roof, the visible surface will generally coordinate with the surrounding shingles.
Flashing
The connection between the cricket, chimney, and surrounding roof requires careful flashing.
Water should be directed around the chimney without being given an easy path beneath the roofing materials.
Because these components work together, adding a cricket is not simply a matter of placing a triangular structure behind a chimney.
How Can You Tell If the Area Behind Your Chimney Has a Problem?
Homeowners should not climb onto a roof to inspect the back of a chimney. Many potential warning signs can be observed from safer locations.
Look for Interior Moisture
Water stains on ceilings or walls near a chimney may indicate that moisture is entering somewhere around the roof penetration.
The visible stain does not necessarily identify the exact entry point because water can travel before becoming noticeable indoors.
Check the Attic When Safely Accessible
If the attic provides safe access to the chimney area, staining or damp materials may indicate that further evaluation is appropriate.
Watch for Recurring Problems
A chimney area that repeatedly requires attention may deserve a more complete evaluation of its drainage and flashing configuration.
A localized roof repair may address damaged materials, but the reason the damage developed should also be understood.
Can a Roof Cricket Be Added to an Existing Roof?
In some situations, yes.
If a roofing professional determines that drainage behind a chimney would benefit from a cricket, one may be incorporated into an existing roofing system. The feasibility and scope depend on the roof design and condition of the surrounding materials.
During Roof Replacement
A roof replacement can be a practical time to evaluate chimney drainage because the existing roofing materials are already being removed.
This gives the roofing team greater access to the underlying structure and makes it easier to evaluate how the cricket, flashing, underlayment, and new roofing materials should work together.
If you are preparing for a replacement, understanding what to expect on the day your roof is replaced can also help you understand why hidden components sometimes receive attention once existing materials are removed.
Why Roof Crickets Matter in Northwest Arkansas
Northwest Arkansas receives rainfall throughout the year, along with thunderstorms and periods of heavy rain. Homes in Fayetteville, Springdale, Rogers, Bentonville, and surrounding communities need roofing systems that can move water efficiently away from vulnerable areas.
A cricket is only one part of that system.
Shingles, underlayment, flashing, valleys, gutters, and roof slope all contribute to water management. A properly designed roof directs water from one component to another until it safely leaves the roof surface.
For homes with larger chimneys, understanding how water moves around that obstruction can help identify drainage concerns before they become recurring problems.
Final Thoughts
A roof cricket may be a relatively small feature, but it can play an important role in managing water around a chimney.
By creating additional slopes behind an obstruction, a cricket redirects rainwater toward the sides instead of allowing it to collect directly behind the chimney. It also works alongside flashing and other roofing materials to help manage an area that can otherwise receive concentrated water exposure.
Not every chimney requires the same solution. Chimney size, roof pitch, location, existing flashing, and drainage patterns all need to be considered.

Frequently Asked Questions
What is the purpose of a roof cricket?
A roof cricket redirects rainwater around a chimney or another large roof obstruction. Its sloped shape divides water flowing down the roof and sends it toward either side instead of allowing it to collect directly behind the obstruction.
Is a roof cricket the same thing as chimney flashing?
No. A roof cricket helps manage the direction of water flow, while flashing helps protect the joints where the chimney meets the roofing system. The two components can work together to manage water around the chimney.
Does every chimney need a roof cricket?
Not every chimney requires the same drainage configuration. Chimney width, roof pitch, location, construction requirements, and water flow all influence whether a cricket is appropriate. A roofing professional can evaluate the specific roof rather than relying on a one-size-fits-all approach.
Can a roof cricket stop a chimney leak?
A cricket may improve drainage around a chimney, but it is not a universal solution for leaks. Moisture can enter through damaged flashing, roofing materials, masonry, sealants, or other components. The source of the leak should be identified before determining the appropriate repair.
Can a roof cricket be installed when replacing my roof?
Yes, a roof replacement can be a good opportunity to evaluate whether a cricket should be added or rebuilt. Removing the existing roofing materials provides better access to the underlying structure, flashing, and surrounding roof area.
