Is Metal Roofing Over Shingles Right for Your Cumming, GA Home? A Topps Roofing Guide
Understanding the "Metal Over Shingles" Approach
The practice of installing metal roofing directly over existing asphalt shingles is not uncommon, and in some specific situations, it can be permitted by building codes. The primary appeal often lies in reducing labor costs and disposal fees associated with a full tear-off. However, this method comes with a significant set of potential drawbacks that can lead to bigger problems down the line for your home. Trapped moisture is a major concern; if the existing shingles have any dampness or are prone to holding water, covering them can lead to rot in the roof deck, mold growth, and eventually compromise the structural integrity of your roof. Additionally, the uneven surface created by old, curled shingles can make it difficult for the new metal panels to lay flat, potentially causing an aesthetically displeasing wavy appearance and creating areas where fasteners may not hold as securely. A thorough inspection of our services would typically begin with assessing the underlying structure.
Why a Proper Tear-Off Matters for Your Cumming, GA Roof
For most reputable roofers, including the experts at Topps Roofing & Construction , a full tear-off of existing shingles before installing a new roof, especially metal, is the recommended best practice. This crucial step allows for a comprehensive inspection of the roof deck beneath. A professional can identify and repair any damaged or rotted plywood, ensuring a solid and stable base for your new metal roof. It also ensures proper installation of new underlayment, which is vital for waterproofing and protecting your home from the elements in Cumming, GA. Without a clean slate, underlying issues like undetected leaks or weakened sheathing could be masked, only to resurface later and lead to costly repairs. A proper tear-off also guarantees that your new metal roof can be installed according to the manufacturer's specifications, which is often a prerequisite for warranty validity. Trusting customer reviews will show you the importance of this step for a lasting roof.
Evaluating Warranties: What to Look For with Topps Roofing
When considering a roofing project, warranties are a critical component, and your mention of a "40-year warranty on the roof & 5-year workmanship warranty" highlights their importance. A 40-year material warranty typically covers defects in the metal panels themselves. However, this warranty can be voided if the roof is not installed according to the manufacturer's specific guidelines, which often preclude installation over existing layers of shingles. Always ask to see the manufacturer's specific installation requirements. A 5-year workmanship warranty covers the quality of the installer's work. While 5 years offers some peace of mind, consider that issues arising from improper installation over existing shingles (like trapped moisture leading to rot) might not become apparent within this shorter timeframe. Always ensure your roofer is familiar with and adheres to both local building codes and manufacturer specifications to protect your investment. When you choose Topps Roofing & Construction, we ensure all aspects of your warranty are clear and valid.
