Custom Angles: Manufacturers may offer custom angles to fit unique roof designs or installation requirements
Manufacturers understand that every roof is unique, and that's why they offer custom angles for wood stove chimney flashing. This bespoke approach ensures that the flashing fits perfectly, regardless of the roof's design or the installation's specific requirements. Custom angles are particularly useful for roofs with unusual slopes, valleys, or hips, where standard flashing might not provide adequate coverage or protection.
The process of ordering custom angles typically involves providing the manufacturer with detailed measurements and specifications of the roof. This might include the roof's pitch, the size and location of any valleys or hips, and the exact position where the chimney will be installed. Using this information, the manufacturer can create flashing that is tailored to the exact dimensions and angles of the roof, ensuring a snug and secure fit.
One of the key benefits of custom angles is that they can help to prevent leaks and water damage. When flashing is properly installed, it creates a watertight seal around the chimney, preventing water from seeping into the roof structure. Custom angles are especially important in this regard, as they can be designed to fit tightly around any unusual roof features, leaving no gaps for water to penetrate.
In addition to their practical benefits, custom angles can also enhance the aesthetic appeal of a roof. By ensuring that the flashing fits perfectly, custom angles can create a clean, professional look that complements the overall design of the roof. This can be particularly important for homeowners who take pride in the appearance of their property, or for commercial buildings where a well-maintained roof can contribute to a positive image.
Overall, custom angles are a valuable option for anyone installing a wood stove chimney. By providing a perfect fit for any roof design, custom angles can help to ensure that the chimney is properly protected from the elements, while also contributing to the overall appearance of the roof.

Angle Selection: Choosing the right angle depends on the roof pitch and the desired clearance from the chimney to the roof
Choosing the right angle for wood stove chimney flashing is crucial to ensure proper installation and functionality. The angle selection process primarily depends on two factors: the pitch of the roof and the desired clearance from the chimney to the roof.
For roofs with a steeper pitch, a larger angle flashing may be required to provide adequate clearance and prevent water from pooling around the chimney base. Conversely, for roofs with a shallower pitch, a smaller angle flashing might suffice. It's essential to measure the roof pitch accurately before selecting the flashing angle. This can be done using a roof pitch gauge or by calculating the rise over run of the roof.
In addition to roof pitch, the desired clearance from the chimney to the roof also plays a significant role in angle selection. Building codes typically require a minimum clearance of 2 inches from the top of the chimney to the roofline. However, some homeowners may prefer a greater clearance for added safety or aesthetic reasons. When determining the required angle, it's important to consider both the minimum code requirements and any additional clearance desired.
Once the roof pitch and desired clearance have been determined, the appropriate flashing angle can be selected. Flashing angles are typically available in standard sizes, such as 90 degrees, 120 degrees, and 150 degrees. In some cases, custom angles may be necessary to accommodate unique roof designs or clearance requirements. When selecting a flashing angle, it's important to choose one that provides the necessary clearance while also ensuring a secure and watertight seal between the chimney and the roof.
Proper angle selection is essential for the long-term performance and safety of a wood stove chimney system. By carefully considering the roof pitch and desired clearance, homeowners can choose the right flashing angle to ensure a secure and functional installation.
