Why Pro Roofers Don’t Recommend Roof-Overs

Roofing is a critical aspect of maintaining a home’s structural integrity, comfort, and overall aesthetic value. When it comes time to address roofing issues, homeowners might be tempted to opt for a “roof-over”, which is a roofing method where a new layer of shingles is installed over the existing roof. However, many reputable roofers have reservations about this practice. US Roofing, a sloped and flat roof replacements expert, explains why contractors tend not to favor roof-overs and why they advocate for a complete roof replacement when necessary.

Increased Weight and Structural Stress

Adding a new layer of shingles on top of existing ones increases the weight the roof frame must support. This additional weight can lead to structural stress and potential failure, particularly in older homes. Given the region’s propensity for heavy snowfall, the added weight from a roof-over can significantly increase the risk of roof collapse under the snow’s weight.

Roofing contractors advocate for a full tear-off and replacement as a safer, more structurally sound approach. This process allows for a comprehensive inspection of the decking and framing, ensuring the roof can support new materials without risk.

Potential for Masking Underlying Issues

One of the primary concerns with roof-overs is that they can easily mask underlying issues with the roof’s structure. Problems such as rotting wood, mold growth, or unseen leaks can cause the roof to deteriorate sight unseen, leading to more significant issues down the line. Contractors understand the importance of addressing these problems head-on to ensure the longevity and safety of the roofing system. Detecting and rectifying these issues early on through roof inspections and possible replacement is also crucial. 

Shortened Roof Life and Warranty Issues

Roof-overs can often result in a shortened lifespan for the new roofing layer. This can lead to premature wear, increased susceptibility to wind damage, and other issues that might not be covered under warranty if the manufacturer’s installation guidelines are not fully adhered to.

Manufacturers’ warranties for roofing materials often stipulate specific conditions for installation, including the need for a clean deck. By ignoring these guidelines with a roof-over, homeowners might find themselves without recourse should their new roof fail prematurely.
