Chimney Crickets and Roof Replacement: Plan the Water Route Behind the Chimney
Roof replacement • NJ, NY and CT homeowner guidance
The uphill side of a chimney is easy for a homeowner to overlook because it may be invisible from the yard. During roof planning, ask how water moving down that roof plane will pass the chimney. A cricket may be part of the answer, but its need and design should be determined for the actual property.
Understand the water route before naming a product
Ask the roofer to show the chimney's position relative to the roof plane and describe the proposed drainage route. A close photograph of sealant at one corner may not explain the whole detail. GAF describes a cricket, also called a saddle, as a feature that directs water around the chimney. Whether your roof needs a new or revised detail requires a property specific assessment and applicable requirements.
Distinguish the cricket from the rest of the chimney
The cricket, surrounding flashing and chimney masonry perform different roles. A roof replacement proposal should explain which of those elements is included and which requires another provider. Do not assume a new roof resolves deteriorated masonry or every possible chimney water source. Ask for a coordinated assessment when the findings cross between roofing and chimney work so responsibility is not left ambiguous after installation.
Ask how the existing detail will be evaluated
Request photographs of the accessible condition and an explanation of what may remain concealed until removal. If the proposal assumes reuse, ask what criteria will support that decision and what would trigger a change. If a new cricket is proposed, ask why and which professional will determine its assembly. Avoid treating a generic size threshold or internet drawing as a complete design for your particular roof.
Make the flashing and transition scope explicit
Ask how the cricket connects with the adjacent roof covering and chimney flashing under the selected system's instructions. The homeowner does not need to dictate fastening or dimensions, but should know that the proposal addresses the complete transition. Clarify whether work on masonry joints or other chimney components is included. A vague line saying chimney sealed leaves too much uncertainty about what is actually being installed.
Coordinate any masonry work before the final roof details
If another trade is needed, agree on the order of work and who protects completed areas during subsequent visits. Ask how a delayed chimney task would affect the roofing schedule and warranty responsibilities. The point is to avoid installing a finished roof detail only to disturb it for work that was already known to be necessary. Keep the shared plan with the contract and any approved changes.
Document the completed arrangement
Request useful stage photographs before concealed details are covered, together with a final view where safely obtainable by the contractor. Keep the product and scope information with those images. If a leak concern later returns, this file helps the professionals understand what was done without assuming that the cricket is automatically the source or that every chimney issue belongs to the roofing warranty.

Frequently asked questions
What is a chimney cricket?
It is a raised roof feature on the uphill side of a chimney that helps route water around it. It is also called a saddle.
Does every chimney need the same cricket detail?
No. The appropriate arrangement depends on the roof, chimney, products and applicable requirements. Ask for a property specific determination.
Is a cricket the same as a chimney cap?
No. They occupy different locations and serve different purposes. Ask the contractor to identify each component included in the proposal.
Will a new cricket fix every chimney leak?
No. Water concerns can involve flashing, masonry or other conditions. The cause needs assessment before choosing the remedy.
Can the roofer assess the back of the chimney from the street?
A street view may be limited. Ask how that area will be evaluated safely and which conditions remain concealed.
Should chimney and roofing contractors coordinate?
Yes, when both scopes are involved. Agree on sequence and responsibilities so later work does not unnecessarily disturb completed roof details.
