Materials Used for Roof Crickets
Various materials such as wood and metal flashing can be utilized to construct roof crickets. The choice of material largely depends on the type of roof and the existing roofing material. For steep-sloped roofs, crickets are often built using wood or metal and can be covered by materials like asphalt shingles, copper, or galvanized steel. On low-slope roofs, crickets are commonly made of sloped rigid insulation and covered by the membrane roofing system itself.
Selecting materials that are congruent with the existing roof boosts durability and resistance to weather, thereby guaranteeing smooth integration and optimal performance. Metal flashing is often used in conjunction with roof crickets to provide a double defense against water seepage, making the roofing system more robust and reliable.
Wood-Framed Structures
Wood-framed roof crickets are primarily used on steep slope roofs. These wood framed structures covered with metal or roofing materials like asphalt shingles ensure they blend in with the rest of the roof.
The triangular pattern of wood-framed crickets effectively directs water away from chimneys, skylights, and HVAC systems, preventing water accumulation and potential damage.
Sloped Rigid Insulation
On low-sloped roofs, roof crickets are typically constructed using rigid insulation. This material is then integrated with the membrane roofing system to form a seamless barrier that prevents water pooling and directs water away from vulnerable areas.
The use of tapered insulation ensures effective water diversion on low-slope roofs while maintaining the integrity of the roofing system, and the proper installation of roof drains contributes to this efficiency.
Metal Flashing
Metal flashing is essential for roof crickets as it provides additional protection against water seepage. In fact, crickets require the flashing, especially in areas prone to heavy rainfall or snow. This material is commonly used to cover roof crickets to ensure their longevity and effectiveness.
The combination of metal flashing with other roofing materials ensures a watertight seal and enhances the overall durability of the roofing system.
Steps to Install a Roof Cricket
The process of installing a roof cricket encompasses several steps aimed at creating a watertight and resilient structure. The process includes:
Preparing the area by cleaning and removing old materials.
Building the cricket frame using precise measurements.
Securely attaching the cricket frame to the roof deck.
After constructing the frame, the following steps are taken to complete the installation:
Sheathing is added for support.
Underlayment is added for waterproofing.
Metal flashing or shingles are installed to match the existing roof materials and ensure a watertight installation.
Preparing the Area
Begin by cleaning the area around the chimney to ensure a smooth installation process. Here are the steps to follow:
Remove old flashing and any debris to prepare the surface for a new roof cricket.
Additionally, remove any existing shingles or other roofing materials from the installation area.
Inspect the roof deck for any damage that needs repair before proceeding.
Building the Cricket Frame
The cricket frame should be built using precise measurements. Cut the framing materials to the appropriate size based on measurements taken from the roof and use compound miter cuts for the cricket rafters to ensure a proper fit.
Securely attach the cricket frame to the roof decking with framing nails to ensure stability and durability on the roof deck.
Adding Sheathing and Underlayment
Adding sheathing provides essential support for the next layer of roofing material. Sheathing should be cut and nailed to cover the entire cricket frame for added support. Underlayment should then be installed over the sheathing to provide a waterproof barrier, ensuring that the entire saddle structure is covered with ice and water protector underlayment for maximum protection against water infiltration.
