The selection of appropriate underlayment material is crucial. Options include asphalt-saturated felt, synthetic underlayments, and rubberized asphalt membranes. Factors to consider include the climate, the building’s design, and the cedar shake’s specifications. Synthetic underlayments generally offer superior tear resistance and UV protection compared to traditional felt.
-
Installation Technique
Proper installation technique involves overlapping the underlayment layers according to manufacturer’s instructions, typically 6 inches horizontally and 12 inches vertically. Fastening the underlayment with appropriate nails or staples is essential to prevent wind uplift. Ensuring a smooth, wrinkle-free surface is also important to provide a solid base for the cedar shakes.
In summary, proper underlayment installation forms a fundamental component of a successful cedar shake siding project. Addressing the moisture barrier function, adhering to code compliance, choosing appropriate materials, and employing correct installation techniques collectively ensure the longevity and weather resistance of the cedar shake cladding.
2. Correct shake exposure
The term “shake exposure” denotes the portion of each shake that remains visible after installation. Its correct determination and consistent execution represent a critical factor in achieving a weathertight and aesthetically pleasing cedar shake exterior. Incorrect exposure can compromise the siding’s protective function and detract from its visual appeal. For example, insufficient exposure leaves too much of each shake covered, wasting material and potentially restricting proper ventilation. Conversely, excessive exposure leaves the shakes vulnerable to water damage and wind uplift, ultimately reducing the siding’s lifespan.
Precise measurement and consistent application of the specified exposure are essential during the installation process. Building codes and manufacturer guidelines typically stipulate acceptable exposure ranges based on the shake’s length and grade. Adherence to these standards ensures that the siding provides adequate protection against the elements and maintains structural integrity. For instance, a longer shake generally allows for a greater exposure, while shakes installed in regions with high wind or heavy precipitation may require a reduced exposure for optimal performance.

Properly integrated flashing safeguards against moisture damage, ensuring the longevity and performance of the siding system.
-
Window and Door Head Flashing
Flashing above windows and doors intercepts water running down the wall and diverts it away from the opening. This typically involves installing a metal or synthetic flashing membrane that extends beneath the underlayment and projects outward, creating a drip edge. Without proper head flashing, water infiltrates the wall cavity, leading to rot and potential structural compromise of the framing around the window or door.
-
Wall-to-Roof Intersections
Where walls meet roofs, step flashing is essential to prevent water from seeping behind the siding. This involves layering individual pieces of flashing with each course of shakes, creating a continuous, waterproof barrier. Each piece of flashing directs water onto the course below, shedding it away from the wall. Incorrect step flashing leads to significant water damage at these critical transition points.
-
Valley Flashing
In roof valleys, where two roof planes meet, valley flashing channels water away from the intersection. This typically employs a wider, more robust flashing material, often metal, that extends up under the underlayment on both sides of the valley. Proper valley flashing is crucial for managing the concentrated water flow in these areas, preventing leaks and associated damage.
-
Kickout Flashing at Roof Terminations
Kickout flashing directs water away from the wall at the bottom edge of a roof. It is installed where a roof terminates against a vertical wall, preventing water from running down the wall and potentially entering the building. This simple but critical detail prevents water damage and prolongs the life of both the siding and the underlying structure.
Incorporating these flashing details correctly is paramount for achieving a weathertight cedar shake siding installation. Neglecting or improperly installing flashing compromises the system’s ability to protect the building from water damage, leading to costly repairs and reduced longevity.

5. Ventilation importance
Adequate ventilation behind cedar shake siding is not merely beneficial; it is fundamentally essential for its long-term performance and the overall health of the building envelope. This ventilation mitigates moisture accumulation, which would otherwise lead to rot, decay, and premature failure of the cedar shakes. Insufficient airflow allows moisture to become trapped, creating an environment conducive to fungal growth and insect infestation. These biological processes degrade the wood fibers, compromising the structural integrity and aesthetic appeal of the siding. A properly ventilated system permits the cedar to breathe, drying out after exposure to rain or humidity, extending its lifespan and reducing maintenance requirements. For example, in regions with high humidity, a lack of ventilation can result in shakes cupping and splitting within a few years, whereas a well-ventilated installation in the same climate can last for decades.
The design of the ventilation system must consider both intake and exhaust points to create a continuous airflow behind the shakes. This often involves incorporating a rainscreen system, which provides an air gap between the sheathing and the siding. The air gap facilitates the movement of air, removing moisture and equalizing pressure. Furthermore, proper detailing around windows, doors, and roof intersections is critical to prevent air leakage and ensure the ventilation system functions as intended. For instance, blocking ventilation pathways with insulation or improper flashing negates the benefits of the air gap, leading to localized moisture accumulation.
In conclusion, recognizing the critical role of ventilation is paramount when executing cedar shake siding installation. Failure to provide adequate airflow inevitably leads to moisture-related problems, diminishing the siding’s durability and performance. Integrating appropriate ventilation strategies, such as rainscreen systems and careful detailing, represents a necessary investment in the longevity and structural integrity of the cedar shake cladding and the building it protects. Ignoring ventilation compromises the entire system, regardless of other installation best practices.
6. Shake selection
