When your roof becomes damaged beyond repair, you might consider a roof-over, thinking it will save you time and money. However, a reputable roof contractor would advise against this practice. Roof-overs involve layering new shingles over old ones, skipping some crucial steps in the roof replacement process.
In this post, we discuss how a roof-over can negatively impact the integrity of your roofing system in the long run.
Short-Term Solution
A fundamental issue with roof-overs is that they fail to address underlying problems with the existing roof structure. Any damage or decay beneath the old shingles is covered up, not repaired. This can lead to severe structural issues, insulation problems, and mold growth over time, as minor issues beneath the new layer go undetected and worsen. In contrast, a complete roof replacement allows the roofer to inspect the decking and other critical areas, ensuring that the new roof’s foundation is sound.
Increased Weight and Stress on the Roof Structure
The additional layers added with a roof-over increase the weight on the roof structure. This may not be immediately problematic, but stresses can accumulate over time, particularly with the added strain from heavy rain or snowfall.
Impact on Roof Maintenance and Warranty
Roof maintenance is an ongoing necessity to prevent costly repairs or premature roof replacement. A roof-over can complicate these efforts by masking issues, making them more difficult to diagnose and address. Furthermore, most roofing manufacturers will not extend a warranty to a roof that has been installed over an existing layer of shingles, which can leave you without coverage if problems arise.
Compliance With Building Codes
In many locations, building codes may limit the number of permissible shingle layers. Adhering to these regulations is vital for the safety and legality of the roofing work.
Environmental Considerations
From an environmental standpoint, roof-overs are less sustainable as they ultimately result in more material waste. Once it becomes necessary to replace the roof, all layers will need to be disposed of, leading to a larger volume of material ending up in landfills. Opting for a roof replacement, while it also generates waste, does so only once and is often a more responsible long-term choice for the environment.
Insurance Benefits
A new roof can potentially lower your insurance premium. Insurance companies often offer discounts for homes equipped with new roofs made of durable materials. A roof-over, lacking in comprehensive structural soundness, may not garner such benefits.
