Cedar shakes are traditional wooden shingles split from cedar logs. They are thicker and visually more appealing than other shingles. However, they provide excellent weather resistance and insulation.

Installing the cedar shakes on the dormer involves a few major steps. First, prepping the surface involves checking the dormer for underlayment, fitting the drip edge, marking the layout with a chalk line, and installing the first course of shakes with nails. “Subsequent courses should be staggered for added durability. Pay close attention to ridge caps and gable ends, seal any exposed areas, and clean up debris for a professional finish.

Understanding Dormers and Their Challenges

Dormers are structural extensions supported by a home. They usually contain windows, bringing natural light and ventilation into the attic or upper floors. Dormers add character to a building’s look and create more usable space; however, they significantly enhance overall aesthetics. Cutting and fitting angles and projections in various intricate geometries is a nightmare.

Angles and Projections: Sophisticated shapes make cutting and fitting processes very delicate.
Flashing Needs: Sealing at the dormer-roof junction is critical to prevent leaks.
Aesthetic Considerations: Ensuring that the secondary roof maintains the visual flow with the primary roof.

A Step-By-Step Guide to Install Cedar Shakes on a Dormer

Here’s what you need to do.

Step 1: Preparing the Surface

A clean and sturdy base ensures the cedar shakes are installed securely.

Inspect the Dormer: Check the dormer’s framing and sheathing for damage or irregularities. Repair or replace any compromised sections.
Gather Tools and Materials: Professionals gather tools such as a hammer, nail gun, utility knife, chalk line, measuring tape, ladder, saw, roofing square, and level. They will also require cedar shakes, roofing felt, underlayment, nails (non-corrosive), flashing, ridge caps, and caulk.
Apply Underlayment: Lay down a waterproof underlayment (like roofing felt or synthetic membrane) to provide a moisture barrier. Overlap the layers to direct water away from the roof.
Install Drip Edge: Attach a metal drip edge along the dormer’s edges to prevent water seepage and protect the underlayment.

Step 2: Marking the Layout

Accurate marking ensures even alignment and professional aesthetics.

Use a Chalk Line: Snap horizontal chalk lines across the dormer to guide shake placement.
Maintain Exposure Consistency: Mark guidelines for the exposure (the visible portion of each shake), usually between 5 to 10 inches, depending on the shakes’ size and design preferences.

Step 3: Installing the First Course

The first row of cedar shakes sets the foundation for the entire installation.

Start at the Bottom Edge: Place the shakes overhanging the drip edge by about 1 inch.
Align Precisely: Ensure the shakes are level and evenly spaced with small gaps (1/8 inch) for wood expansion.
Nail Securely: For every shake, use two nails, some 1 inch off the edges and 2 inches from the exposure line.

Step 4: Installing Subsequent Rows

Stagger the Joints: For the second row, alternate the shakes by cutting one in half to shift the joints. This ensures sturdiness and a better pattern appearance.
Install with Care: Make the same nailing pattern as the first row and maintain the overlaps and staggering for each subsequent row.
Repeat Until Complete: Continue this up the dormer, cutting the shakes as necessary to fit. Be sure to stagger joints every row for strength and visual appearance.

Step 5: Handling Ridge and Gable Ends

Finishing the ridge and gable ends ensures both aesthetic appeal and weather resistance.

Install Ridge Vents and Caps: Utilize ridge cap shakes or cut standard shakes to size. Ensure that each shake overlaps well to cover the entire length of the ridge of a dormer.
Secure the Gables: With neatly trimmed shakes along the gable ends, ensure they line up perfectly with the slope of the dormer roof.

Step 6: Quality Check and Final Touches

A final quality check on the installed roof ensures its durability and appearance.

Inspect for Gaps or Misalignment: Adjust shakes or flashing to eliminate gaps or crooked lines.
Seal Exposed Areas: Apply caulk or sealant on the exposed nails or joints that may let water into the dormer.
Clean Up: Remove debris, excess materials, and sawdust to leave a polished finish.

How Much Does Cedar Shakes Installation on Domer Cost?

The cost of installing cedar shakes on a dormer can vary based on several factors:

Material Costs: Cedar shakes typically range from $3 to $6 per square foot.
Labor Costs: Labor may add another $2 to $4 per square foot.
Dormer Size: Larger dormers will naturally require more materials and labor.
Complexity: Difficult rooflines or intricate designs may increase labor costs.
Region: Prices might vary slightly depending on local market conditions.
Additional Features: Custom finishes or treatments could also influence the overall cost.

It’s advisable to get multiple quotes for an accurate estimate.

Maintenance Tips for Your Cedar Shakes

Professional Inspections: A local roofing contractor assesses the condition and potential problems that must be addressed every few years.
Cleaning: Clean up debris, leaves, and moss daily from the roof. Never use a power washer, which may damage the shake; use a soft-bristle brush or low-pressure water spray.
Protective Treatment: Apply protective sealer every few years to preserve the wood’s natural oils, which fortify its ability to resist weathering.
Prune Overhanging Branches: Trim branches that hang over the cedar shake roof to limit the amount of debris falling upon it and reduce storm damage.

Cedar Shakes Benefits

Here are some benefits that cedar shakes provide:

Natural Aesthetic: Their rustic looks enhance the beauty of any place.
Durability: Since cedar is resistant to warping and cracking, these will last longer.
Insulation: It also offers excellent thermal insulation that reduces energy expenditure.
Low Maintenance: Requires less maintenance compared to other materials.
Resistance to Decay: The material naturally resists insects and decay, thus providing a long-lived material.
Eco-Friendly: Made from renewable resources, they are also environmentally friendly.

Conclusion

There are so many steps involved in installing cedar shakes on a dormer. The first step is to clean the surface by inspecting the dormer, underlayment, and drip edge installation. Mark the layout with a chalk line; install the first row of shakes by nailing into place. Other rows must be staggered, making it look more rugged, while maximum care must be taken at ridge caps and gable ends. Final check for quality and seal the exposed areas while cleaning up the debris for a finished look.
