When it comes to roofing decisions, homeowners often grapple with a crucial question: Should I replace my existing roof or put a new layer on top of it? At Olympus Roofing, we’re here to help you figure out the best choice for your home. For a comprehensive overview, check out our video where Joe from Olympus Roofing breaks down the pros and cons.
Watch our video, “Can I Put a New Roof Over the Top of My Existing Roof?” here. In this video, Joe dives into the details and provides expert advice on whether adding a new roof on top of an old one or opting for a total replacement is the right move.
Understanding the Basics: Can vs. Should
The core of this question is distinguishing between what you can do and what you should do. Legally, you can put a new roof on top of an old one. Utah state code allows for up to two layers of roofing on a single structure. But just because it’s permitted doesn’t always mean it’s the best or most effective solution.
The Technical Perspective: Building Codes and Regulations
Utah’s building codes permit putting a second layer of roofing material, known as a “roof-over.” This method can be less labor-intensive and more affordable compared to a full roof replacement, which involves tearing off the old roof. However, there are several factors to weigh before making this choice.
- Roofing Material and Condition: Your existing roof needs to be in decent shape. If it has significant issues—such as leaks, extensive damage, or structural problems—overlaying a new roof won’t address these concerns and could even make them worse.
- Layer Limitations: Building codes typically limit you to a maximum of two layers of roofing. If your home already has one overlay, adding another layer will be your limit. Future issues with the roof will require a full replacement.
- Weight Considerations: Adding a new layer increases the weight on your home’s structure. Roofs are designed to handle a certain amount of weight. Additional layers can put more stress on the structure and potentially lead to long-term problems.
The Olympus Roofing Perspective: Why We Recommend a Full Replacement
At Olympus Roofing, we take pride in doing the job right every time. Our commitment to quality and long-lasting results is why we generally steer clear of putting a new layer over an old one. Here’s why we prefer a full roof replacement:
- Comprehensive Inspection: A full roof replacement allows us to carry out a thorough inspection of your existing roof’s condition. This helps us spot and address underlying issues such as water damage, rotting wood, or structural problems that might not be visible with a simple overlay.
- Proper Installation: Putting a new roof over an old one can compromise the integrity of the underlying layers. By starting from scratch with a complete removal, we ensure that the new roofing material is installed correctly and securely, meeting current standards and best practices.
- Warranty Considerations: Opting for a roof overlay can complicate warranty coverage. At Olympus Roofing, we aim to offer the best possible warranties on our work. However, if we put a second layer of roofing on, we cannot provide the same level of warranty or guarantee the roof’s long-term performance.
- Longevity and Performance: A new roof installed over an old one might not last as long as a fully new installation. The new roofing material may not adhere properly to the old layer, potentially leading to issues like leaks or premature deterioration.
The Benefits of a Full Roof Replacement
Choosing a full roof replacement rather than a roof overlay brings several advantages:
- Enhanced Durability: A full replacement ensures that your new roof is installed on a clean, solid surface. This enhances its durability and lifespan, providing long-term peace of mind.
- Improved Energy Efficiency: A complete replacement allows us to address insulation and ventilation issues that might affect your home’s energy efficiency. Improved insulation and ventilation can lead to lower energy bills and a more comfortable living environment.
- Increased Home Value: A new roof can significantly boost your home’s curb appeal and market value. Potential buyers will appreciate the security and longevity of a new, high-quality roof.
- Warranty Protection: With a full roof replacement, you receive a comprehensive warranty on both the materials and labor. This warranty provides added protection and assurance that your investment is well-protected.
