What Is a Roof Cricket?
A roof cricket is a small, peaked structure installed on the high side of a chimney or where two roof slopes meet. Its main purpose is to divert water and debris away from vulnerable areas, preventing pooling and leaks. Residents of Corinth, NY, will often see a cricket as a mini-roof that directs water around a chimney or similar obstacle.
Crickets are typically constructed of roofing materials that match the rest of the roof—such as shingles or metal flashing—and are built at the same pitch as the primary roof, or sometimes slightly steeper to encourage water to flow swiftly around the protrusion.
Why Do Roof Crickets Matter in Corinth’s Climate?
In Corinth, where winters can be snowy and springs are often rainy, proper water management on a roof is essential. Roof crickets help shield flashing and prevent leaks by ensuring water can't linger against chimneys or walls—areas highly prone to moisture intrusion.
Without a cricket, melting snow and rainwater can accumulate on the uphill side of a chimney. This may seep under flashing or shingles, increasing the risk of water damage or ice dams—a familiar challenge in the region’s harsh winters.
Where Are Roof Crickets Installed Most Often?
The most common spot for a roof cricket in local homes is behind a large chimney that’s wider than about 30 inches. Small chimneys may shed water more easily, but wider structures give rain and runoff a place to pool. Crickets are also used where two roof planes meet in a "valley" and water flow becomes concentrated.
For older homes in Corinth with more complex roofs or prominent fireplaces, retrofitting a cricket can be a beneficial upgrade during roof repair or replacement.
What Happens If a Roof Doesn’t Have a Cricket?
If a roof lacks a cricket behind a chimney or along a problematic joint, water is more likely to pond and penetrate roofing materials. Over time, this can lead to:
- Rotting roof deck or rafters
- Damaged masonry
- Stained interior ceilings and walls
- Mold or mildew growth
- Ice dam formation (especially in late winter and early spring)
- Higher long-term repair costs
Local homes built before modern building codes or roofing standards sometimes lack crickets, but their absence is a frequent cause of recurring leaks around chimneys, especially after heavy melts or extended rain.
Are Roof Crickets Required by Building Codes in Corinth?
Modern building codes utilized in the city require roof crickets behind larger chimneys. Local regulations generally align with international residential codes, which stipulate crickets for any chimney 30 inches wide or more, measured perpendicular to the roof slope.
Inspectors may check for crickets during new construction or major roofing work. In some older properties, crickets may not be present because homes were built before these codes were widely used. However, adding a cricket during re-roofing is considered a best practice for long-term preservation, even if not strictly required.
What Should Homeowners Watch For?
Residents of Corinth can check for common signs that a cricket may be missing or failing, including:
- Water stains, bubbling, or peeling paint near the chimney inside the home
- Moss or algae growth on the uphill side of the chimney exterior
- Signs of pooling water, sagging, or visible gaps in flashing around the chimney

After a heavy snow or after rain, the area behind the chimney is especially vulnerable. In climates with freeze and thaw cycles, trapped water can worsen underlying damage by expanding small openings.
How Are Roof Crickets Built?
A cricket is framed with lumber to form a ridge that meets the roof at an angle, then covered with roofing underlayment and matching shingles or metal. Copper or galvanized steel flashing is often used to ensure a watertight seal where the new structure meets both the roof and the chimney’s masonry.
For heavily sloped roofs, the cricket's ridge may be quite sharp, while low-slope roofs will have a more gradual pitch. The design is custom-fitted to match the roof's angles and the width of the chimney or obstruction.
Can Homeowners Add a Cricket to an Existing Roof?
It’s possible to retrofit a cricket on an existing roof, either as a standalone improvement or as part of a larger roof replacement project. Adding a cricket is typically more involved than a minor patch, since it requires altering roof framing and ensuring seamless integration with the current waterproofing system.
While some experienced DIY homeowners may tackle minor roofing jobs, cricket installation around chimneys involves structural carpentry, weatherproofing, and safety considerations, often requiring specialized knowledge of roof drainage and flashing details.
Common Misconceptions About Roof Crickets
Some area homeowners believe that smaller chimneys or newer roofs don’t need crickets. However, even with modern flashing, persistent water flow against a chimney can eventually cause leaks. Others assume that roof sealants alone are enough to prevent water intrusion. While sealants may temporarily help, they’re not a substitute for proper water-shedding design like a cricket.
A further misconception is that adding a cricket is only valuable in rainy climates. In reality, it’s just as important in snowy regions like Corinth, as freeze-thaw cycles and melting snow can quickly exploit any weakness in the roof structure.
Practical Example for Corinth Households
Imagine a typical brick chimney, about 36 inches wide, rising from a moderately pitched roof. During spring snowmelt, water pools against the back of the chimney, soaking into the flashing and the roof’s plywood deck. Before long, brown stains appear on the living room ceiling. Retrofitting a durable cricket diverts meltwater to either side, protecting the roof and the inside of the home from further water damage.
