Rolling Roofs Over Existing Shingles A Practical Guide

When it comes to roofing, homeowners often face the dilemma of whether to replace their old roof or to cover it up with a new layer. One increasingly popular solution is to roll roofing over existing shingles. This method offers a variety of benefits, making it an appealing choice for many homeowners looking to save time and money while still protecting their homes from the elements.

What is Roll Roofing?

Roll roofing is a type of roofing material that is available in large rolls rather than standard shingles. It typically consists of asphalt-saturated materials, making it weather-resistant and durable. Roll roofing comes in various styles and textures, allowing homeowners to choose a look that complements their home. It's most commonly used for low-slope roofs, but many homeowners consider it an option for sloped roofs as well.

Benefits of Rolling Roofs Over Existing Shingles

1. Cost-Effective Solution One of the most significant advantages of rolling roofing is the cost savings. Removing existing shingles can be a labor-intensive process that adds to the overall expense of a roofing project. By opting to install roll roofing over existing shingles, homeowners can save on the costs of labor, disposal, and new materials.

2. Time-Saving The installation of roll roofing is generally faster than a complete roof replacement. Since there’s no need to tear off the old shingles, the process can be completed in a fraction of the time, reducing inconvenience for homeowners and allowing them to enjoy their newly roofed homes sooner.

3. Minimized Waste By covering existing shingles rather than removing them, homeowners can significantly reduce the amount of waste sent to landfills. This is not only beneficial for the environment but can also align with a homeowner’s eco-conscious values.

4. Added Protection Installing roll roofing over existing shingles can provide an additional layer of protection for the home. This extra layer can help prevent leaks and increase insulation, potentially lowering heating and cooling costs.

5. Enhanced Aesthetic Options Modern roll roofing comes in various colors and finishes, allowing homeowners to improve their home’s curb appeal. Whether for a unique aesthetic or simply to complement the existing style of the house, roll roofing can enhance the overall look of a home.

Considerations Before Installation

While there are numerous advantages to rolling roofing over existing shingles, there are a few factors to consider before proceeding

- Weight Limitations Before adding another layer, it's essential to check the structural integrity of the roof. Most roofs can handle an additional layer, but consulting with a roofing professional is advisable to avoid overloading the structure.

- Condition of Existing Shingles The existing shingles must be in relatively good condition. If they are severely damaged, curling, or missing, they may need to be replaced or repaired first. This ensures that the new roofing layer will adhere properly and provide adequate protection.

- Local Building Codes Many regions have regulations regarding the number of roofing layers allowed. Be sure to check local building codes to ensure compliance before starting the project.

- Installation Techniques Proper installation is crucial for the longevity of a rolled roofing system. It is often recommended to hire a professional who understands the correct techniques and can ensure that the roof is installed effectively.

Conclusion

Rolling roofing over existing shingles offers a practical and cost-effective solution for many homeowners looking to update their roofs without the hassle of a full replacement. With the potential for time savings, minimal waste, and enhanced aesthetics, this method can transform an old roof into a durable protective layer. However, homeowners should carefully assess their existing roof’s condition, consult local regulations, and consider professional installation to maximize the benefits of this approach. With the right planning and execution, rolling roofing can be a smart investment for long-term home protection.
