Asphalt Shingles Over Cedar Shake Roof A Comprehensive Guide

When it comes to roofing options for your home, you may find yourself weighing the pros and cons of various materials. Among these choices, asphalt shingles and cedar shake are two popular options, each with its unique benefits and drawbacks. However, an increasing number of homeowners are considering the installation of asphalt shingles over existing cedar shake roofs as a viable solution for both aesthetics and practicality. This article explores the reasoning behind this choice, focuses on installation techniques, and highlights important considerations.

Understanding the Basics

Cedar shake roofs are known for their natural beauty and durability. However, they come with challenges, such as susceptibility to rot, warping, and insect infestations. On the other hand, asphalt shingles are appreciated for their affordability, ease of installation, and low maintenance. They also come in a vast array of colors and styles, providing homeowners with the opportunity to enhance their home's curb appeal.

Given these contrasting characteristics, combining asphalt shingles with cedar shake roofs can offer the best of both worlds. Homeowners can retain the charm of cedar while benefiting from the additional protection and aesthetic versatility provided by asphalt.

Benefits of Asphalt Shingles Over Cedar Shake

1. Cost-Effectiveness Replacing a worn-out cedar shake roof can be costly. By installing asphalt shingles directly over the existing shakes, homeowners can save on both materials and labor costs associated with a complete roof replacement.

2. Enhanced Durability Asphalt shingles are manufactured to withstand various weather conditions, from heavy rain to direct sunlight. This added layer can help protect the underlying cedar shake from the elements, extending its lifespan.

3. Improved Insulation The additional layer of insulation may enhance energy efficiency in your home, ultimately leading to savings on heating and cooling costs.

4. Aesthetic Versatility With a wide range of styles, colors, and textures, asphalt shingles can be selected to either complement or dramatically change the visual appeal of your home. They can provide a sleek, modern look or mimic the traditional appearance of wood shakes.

5. Simplified Installation Asphalt shingles can be applied relatively quickly and easily over cedar shakes, reducing the installation time and labor costs, making it a more efficient roofing solution.

Installation Process

Installing asphalt shingles over cedar shake requires careful planning and execution. It's essential to check local building codes, as some areas may have regulations that affect this type of installation. The following steps outline the general installation process

1. Inspection Before proceeding, conduct a thorough inspection of the cedar shake roof. Look for signs of severe damage or extensive rot, as this could compromise the overall integrity of the new shingles.

2. Cleaning Remove any debris, such as leaves or dirt, from the roof’s surface. A clean surface is crucial for effective adhesion of the new shingles.

3. Underlayment Install a waterproof underlayment over the cedar shakes. This acts as an extra barrier against moisture and helps increase the shingles' lifespan.

4. Shingle Installation Begin laying the asphalt shingles from the bottom of the roof upwards, overlapping each row as recommended by the manufacturer. Ensure that nails are driven in appropriately to avoid leaks.

5. Finishing Touches Pay attention to roof details, such as vents and chimneys, ensuring that they are properly flashed and sealed.

Important Considerations

While installing asphalt shingles over cedar shake can be beneficial, there are a few critical points to consider

- Weight The added weight of new shingles might create strain on the structure. Verify that your roof can safely support the additional load.

- Ventilation Cedar shakes require good ventilation to prevent moisture buildup. Ensure the new roofing system maintains adequate airflow to avoid potential issues.

- Longevity Although this method can extend the lifespan of the underlying cedar shakes, it's crucial to maintain and monitor both layers for signs of wear and tear.

Conclusion

In conclusion, installing asphalt shingles over cedar shake roofs presents an intriguing option for many homeowners. This combination allows for the aesthetic benefits of wood while enhancing durability, cost-effectiveness, and versatility. With proper planning, installation, and maintenance, this roofing solution can provide a reliable and attractive shelter for your home for years to come. If you’re considering this combination, it may be beneficial to consult with a professional roofing contractor to ensure the best outcome for your project.
