Installing Roll Roofing Over Existing Shingles for Efficient Roof Repair Solutions

Rolling Roofing Over Shingles A Practical Guide

When it comes to roofing, homeowners often face the challenge of maintaining the integrity and aesthetic appeal of their homes. One common solution to roofing issues is the application of roll roofing over existing shingles. This method can save time and money, but it’s essential to understand the process, benefits, and potential pitfalls.

Understanding Roll Roofing

Roll roofing is a type of roofing material that comes in large rolls, typically made of asphalt-saturated felt or fiberglass. It is lightweight, easy to install, and often used in low-slope roofing applications, such as sheds and flat roofs. Due to its ease of use and affordability, roll roofing is a popular choice for both residential and commercial properties.

Benefits of Installing Roll Roofing Over Shingles

1. Cost-Effective One of the main advantages of installing roll roofing over existing shingles is cost-efficiency. Removing shingles can be labor-intensive and costly. By overlaying roll roofing, you can save on labor and disposal fees.

2. Speed and Efficiency The installation process for roll roofing is generally quicker than traditional roofing methods. Experienced roofers can install roll roofing in a fraction of the time it would take to remove and replace shingles.

3. Protection from Elements If your shingles are still in decent shape, roll roofing can provide an added layer of protection. This helps to prevent water infiltration and prolongs the lifespan of your roof.

4. Minimal Disruption Since there's no need to tear off existing shingles, the installation process is less disruptive to your daily life and the exterior of your home.

1. Assess the Condition of Existing Shingles Before proceeding, it’s crucial to evaluate the condition of your existing shingles. If they are severely damaged, warped, or curling, it may be better to remove them entirely.

2. Clean the Surface To ensure proper adhesion, clean the existing shingles thoroughly. Remove any debris, moss, or loose materials. A clean surface will help the roll roofing bond effectively.

3. Install Underlayment (Optional) Some homeowners choose to install an underlayment over the shingles for additional moisture protection. This step is optional but can enhance the overall durability of the roof.

4. Measure and Cut the Roll Roofing Measure the sections of your roof and cut the roll roofing to size. It’s essential to be precise to minimize waste and ensure a snug fit.

5. Lay the Roll Roofing Starting from the bottom edge of the roof, roll out the roofing material. Make sure that each subsequent row overlaps the previous one by at least six inches. Proper overlap is critical to prevent water from seeping through the seams.

6. Secure the Roll Roofing Use roofing nails or adhesive, depending on the manufacturer’s recommendations, to secure the roll roofing in place. Ensure that you fasten it adequately to withstand strong winds and adverse weather conditions.

7. Seal Edges and Seams After laying down the roll roofing, apply a roofing sealant along the edges and seams to provide additional waterproofing. This step helps to prevent leaks and extends the life of your roofing system.

8. Final Inspection Once the installation is completed, conduct a thorough inspection to ensure everything is secured and properly installed. Look for any areas that may require additional sealing or fastening.

Considerations and Challenges

While installing roll roofing over shingles can be a viable option, it’s essential to keep some considerations in mind. Local building codes may have restrictions on overlaying roofing materials, so it’s always a good idea to check with your local authorities. Additionally, the increase in weight on your roof should be evaluated, especially if multiple layers of roofing have already been added.

In conclusion, rolling roofing over shingles presents a practical and economical solution for homeowners looking to extend the life of their roofs. By understanding the process and executing it correctly, you can enhance your home’s protection against the elements and improve its overall aesthetic without the need for extensive renovation. Always consider consulting with a roofing professional to ascertain that this method aligns with your specific roofing needs.
