The Anatomy of a Roof Cricket

A roof cricket’s design is a masterclass in efficiency and simplicity, especially for a low slope roof system. Picture a triangular structure snugly installed behind a chimney or skylight, its sloping sides and a small ridge on top working in concert to redirect water away from your roofing system’s critical elements. The cricket’s gable design isn’t just for aesthetics; it’s engineered to match the slope of your roof, allowing water to flow smoothly towards drainage points.

Whether your roof is a steep mountain or a gentle hill, crickets can be tailored to fit. They can mirror the pitch of your roof or offer a steeper angle for more aggressive water diversion, referred to as ‘saddles’ in the roofing vernacular. The ridge must be level, and the sides must align with your roof’s slope, creating an effective channel that prevents water from pooling against the chimney and inviting issues.

Roof Cricket vs. Traditional Roof Design

Although traditional roof designs serve their purpose, they often lack in their ability to prevent water and debris accumulation at critical points. This design shortcoming is addressed by roof crickets. They stand as a bulwark against the potential damage caused by standing water, ensuring that even heavy rainfall is managed and redistributed to safeguard your roofing materials from deterioration. In addition to roof crickets, roof curbs can also play a role in enhancing the overall protection of your roofing system.

It’s this proactive approach to water management that sets roof crickets apart. By eliminating water ponding and the risk of structural damage that comes with it, they not only extend the lifespan of the roof but also offer a cost-effective preventative measure.

The difference is clear: worthwhile investment roof crickets are not just an addition to your roof; they are a strategic enhancement that serves to protect your investment for years to come.

When and Where to Install Roof Crickets

Following building codes goes beyond mere compliance; it’s about crafting a durable cricket with accuracy and proficiency. Roof cricket building codes on certain chimneys aren’t just recommended; they’re mandated, highlighting their importance in the grand scheme of roof construction and regulatory compliance.

Identifying High-Risk Zones on Your Roof

Some zones of your roof are more susceptible to the whims of water than others. Areas around large rooftop units like HVAC systems and unprotected skylights are particularly vulnerable to ponding, as water seeks out any opportunity to collect. It’s in these high-risk zones that contractors often install roof crickets, positioning them on the higher side of chimneys or at the meeting point of different roof sections to ensure that water is diverted rather than accumulated.

For chimneys that sit at the bottom of a roof slope or are surrounded by slopes that direct water towards them, the installation of a roof cricket is critical to prevent leakage. In regions with substantial rainfall or snow accumulations, the design of chimney crickets is customized to ensure that water is effectively steered away from the chimney base. Identifying these zones is the first step to fortifying your roof against the elements.

Selecting Materials for Your Roof Cricket

Creating a roof cricket resembles the selection of suitable battle armor; chosen materials should be sturdy, durable, and prepared to withstand any weather conditions. For steep-sloped roofs, the traditional wood framework provides a sturdy foundation, while metal flashing or asphalt shingles shield it from the elements. On the other hand, low-sloped roofs, such as a flat roof, might call for a more specialized approach, utilizing sloped rigid insulation beneath the membrane roofing system for optimal protection.

Metals such as copper and galvanized steel are often the materials of choice for roof cricket construction, thanks to their exceptional resistance to rusting and corrosion. In the commercial realm, tapered insulation panels are frequently employed as a roofing material to create the necessary slope for water diversion, marrying functionality with a keen awareness of the roofing system’s specific needs.

Compatibility with Roofing System

The interdependent relationship between a roof cricket and the roofing system it safeguards is of paramount importance. The materials used for the cricket must be in harmony with the roof’s slope and the maximum acceptable length to width ratio, a calculation that varies depending on the roof’s surface slope. For the flat and low-slope roof systems that are common in commercial buildings, materials such as insulation are typically chosen for their compatibility.

A metal roof cricket, seamlessly integrated with a metal roof, is a prime example of this compatibility in action. The necessity of roof crickets on flat or low-slope roofs is particularly evident, as they play a pivotal role in preventing water collection and ensuring proper runoff. Moreover, taking into account the roofing materials and regional weather conditions, such as high snowfall areas and extreme temperatures, is essential for the cricket’s compatibility and effectiveness.

Durability and Weather Resistance

The true test of a roof cricket lies in its ability to endure. The materials selected must be durable and capable of withstanding diverse weather conditions over extended periods. That’s where metals like copper and galvanized steel come into play, offering high resistance to the elements and ensuring the roof cricket remains steadfast through seasons of rain, snow, and sunshine.

Incorporating metal flashing into the cricket’s construction is not just about durability; it’s a crucial step in creating an impenetrable barrier against water seepage into the roof deck. This preventive measure is key to averting potential leaks and the associated structural damages they can bring about.
