How to Install a Roof Underlayment for a Cedar Shake Roof

Understanding the Importance of Roof Underlayment for Cedar Shake Roofs

When installing a cedar shake roof, one of the most crucial elements is the underlayment. This material serves as a barrier against water infiltration, moisture buildup, and temperature fluctuations, protecting your home from damage. Proper installation is vital to ensure long-lasting performance and avoid costly repairs.

Step 1: Lay the First Row of Underlayment

Begin at the edge of the roof, starting from the eaves. Roll out the underlayment horizontally, ensuring it overlaps the edge of the roof by at least 2 inches. Secure the material with roofing nails or staples.

Step 2: Overlap Successive Rows

Continue laying rows of underlayment, ensuring each row overlaps the previous one by at least 3-4 inches. This overlap creates a watertight seal, preventing leaks.

Step 3: Install Around Roof Penetrations

For roof penetrations such as vents and chimneys, use special underlayment flashing to seal these areas. This extra precaution ensures moisture doesn’t seep through these vulnerable spots.

Step 4: Final Inspection

Once all underlayment has been installed, inspect the roof to ensure no areas are missed or improperly sealed. Check for loose nails or staples that could cause the material to shift.

4. Common Mistakes to Avoid During Installation

While installing underlayment for a cedar shake roof is straightforward, some common mistakes can undermine the installation process. Be mindful of these errors:

Not overlapping the rows enough, which can allow water to seep through
Using the wrong type of underlayment material for your climate or roof style
Skipping the inspection of the decking before installation
Improperly securing the underlayment, leading to slippage or loosening

5. Real-Life Case: Installing Underlayment on a Cedar Shake Roof

Many homeowners have found that installing a proper roof underlayment significantly improves the lifespan of their cedar shake roof. For example, one homeowner in California shared their experience of how switching from a felt underlayment to a high-performance synthetic underlayment helped them avoid leaks during the heavy rains last winter.
