Installing Rolled Roofing Over Existing Shingles for Enhanced Roofing Solutions

Installing Rolled Roofing Over Shingles A Comprehensive Guide

When it comes to roofing, homeowners often seek effective and economical solutions that can extend the life of their roofs. One such method is installing rolled roofing over existing shingles. This approach offers several advantages, including cost savings, ease of installation, and additional weather protection. However, before embarking on this project, it’s essential to understand the implications, preparation, and execution involved.

Understanding Rolled Roofing

Rolled roofing is a type of roofing material typically made from asphalt. It is sold in large rolls, making it easy to transport and install. The material is lightweight and comes with a self-adhesive backing, which simplifies the installation process. Rolled roofing is a popular choice for flat or low-slope roofs, but it can also be used over sloped surfaces like shingles.

Benefits of Installing Rolled Roofing Over Shingles

1. Cost-Effectiveness One of the primary reasons homeowners opt for rolled roofing is the cost savings. It is generally cheaper than traditional shingles or tile roofing, making it an attractive option for those looking to save money.

2. Simplicity of Installation Compared to other roofing materials, rolled roofing is straightforward to install. Homeowners with some DIY skills can tackle this project, reducing labor costs.

3. Adding an Extra Layer of Protection By installing rolled roofing over existing shingles, you are effectively adding another barrier against the elements. This layer can help prevent leaks and reduce wear on the underlying shingles.

4. Quick Installation Rolled roofing can usually be installed in a day, depending on the size of the roof, which means less disruption to your daily life.

Preparing to Install Rolled Roofing

Before starting the installation process, homeowners should conduct a thorough inspection of their existing shingles. Look for missing, damaged, or curling shingles, as these may compromise the integrity of the new layer. Repair or replace any problematic areas before proceeding.

Additionally, ensure that the roof is clean and free of debris. A smooth surface will help the rolled roofing adhere better and create a more watertight seal.

Installation Process

1. Measure and Cut Measure the roof area where you will apply the rolled roofing. Cut the rolls to appropriate lengths, allowing for some overlap to ensure proper sealing.

2. Lay the First Roll Start at the lowest point of the roof and carefully lay the first roll, making sure it aligns properly. Unroll it gently to avoid creases.

3. Adhere the Material Peel back the self-adhesive backing and press the rolled roofing firmly onto the shingles. Use a roof roller to ensure it adheres well and avoid any air pockets or wrinkles.

4. Overlap Subsequent Rolls Continue laying additional rolls, overlapping each one by at least 6 inches. This overlap is critical for preventing water intrusion.

5. Seal the Edges Once all the rolls are in place, seal the edges and any seams with roofing cement or self-adhesive flashing tape for added waterproofing.

6. Final Inspection After installation, conduct a thorough inspection to ensure there are no gaps or loose areas in the roofing material.

Conclusion

Installing rolled roofing over shingles can be a practical solution for homeowners looking to enhance their roof's durability and lifespan without incurring significant expenses. With the right preparation and careful installation, rolled roofing can provide an effective shield against the weather. Always consider local building codes and consult with roofing professionals if you have any doubts about the process. A well-installed rolled roof can not only protect your home but also add value to your property.
