Installing New Roofing Over Existing Shingles for Improved Home Protection and Aesthetic Appeal

Rolling Roofing Over Existing Shingles A Complete Guide

When it comes to roofing, homeowners often seek cost-effective and efficient solutions to extend the lifespan of their roofs. One method that has gained popularity is rolling roofing over existing shingles. This technique can save time and money while providing a new protective layer. In this article, we will explore the advantages and considerations of this roofing method, including installation processes and potential drawbacks.

Understanding Rolling Roofing

Rolling roofing, also known as rolled roofing, is a type of roofing material that comes in large rolls and is typically made from asphalt. It is often used in residential applications for low-slope roofs or flat roofs. The primary appeal of rolled roofing lies in its easy installation and affordability compared to standard shingles.

Advantages of Rolling Roofing Over Existing Shingles

1. Cost-Effectiveness One of the most significant benefits of rolling roofing is the cost savings. Homeowners can avoid the expenses associated with tearing off old shingles, including labor and disposal fees. By installing rolled roofing directly over existing shingles, significant savings can be achieved.

2. Time-Saving The installation process for rolling roofing is relatively quick. Instead of a lengthy tear-off and replacement, rolling roofing can be laid down directly over the old shingles. This not only reduces labor hours but also minimizes disruption to the household.

3. Improved Energy Efficiency When properly installed, rolling roofing can enhance energy efficiency. Certain types of rolled roofing products are designed with reflective surfaces that help to deflect sunlight, potentially lowering cooling costs during hot months.

4. Protection Against Leaks Rolling roofing can provide an additional layer of protection against moisture and leaks. This can be particularly beneficial for homes in areas prone to heavy rain or snowfall.

5. Aesthetic Appeal While rolling roofing might not offer the traditional aesthetic appeal of standard shingles, it can still improve the overall look of an aging roof. Modern rolled roofing comes in various colors and styles, allowing homeowners to choose an option that complements their home’s architecture.

Installation Considerations

Before rolling roofing over existing shingles, several factors should be taken into account

1. Roof Condition The underlying shingles must be in relatively good condition. Any signs of severe damage, such as extensive curling, missing shingles, or significant wear, should be addressed before installation to ensure a stable foundation for the rolled roofing.

2. Building Codes Check local building codes and regulations. Some areas may have specific requirements regarding roofing materials and installation practices that must be adhered to.

3. Ventilation Ensure that proper ventilation is maintained. Adding a new layer over existing shingles can trap heat and moisture, leading to potential issues like mold and reduced roof lifespan.

4. Professional Help While rolling roofing is easier to install than traditional shingles, hiring a professional roofer can ensure that the job is done correctly. Professionals can identify potential underlying issues and guarantee that the rolled roofing adheres properly.

Potential Drawbacks

While rolling roofing offers many advantages, there are some drawbacks to consider as well. Its lifespan is generally shorter than traditional shingles, typically lasting 10 to 15 years. Additionally, rolled roofing is more susceptible to damage from extreme weather conditions, which may be a concern for homeowners in harsher climates.

Conclusion

Rolling roofing over existing shingles can be a smart choice for many homeowners seeking an economical way to refresh their roofs. By understanding the benefits and drawbacks, considering installation requirements, and ensuring proper maintenance, homeowners can make an informed decision that enhances the durability and longevity of their roofing system. Whether you are looking to save money or extend the life of your roof, rolled roofing may be the solution you need.
