Homeowners often consider the option of roof-overs as a method to address their roofing needs. This practice, which involves installing a new layer of shingles over an existing roof, might seem cost-effective and time-saving at first glance. However, many roofing contractors, including those at Homecraft® Inc., are hesitant to recommend this approach. The reasons are grounded in the long-term durability, safety, and overall effectiveness of roofing solutions. Let’s delve into the specifics of why roofing contractors are wary of roof-overs and favor full replacements instead.
One of the primary concerns with roof-overs is the potential for hidden damage. By layering new shingles over old ones, contractors cannot inspect the underlayment or the deck for rot, mold, or other damages. In regions where weather can be unpredictable, underlying issues can exacerbate over time, leading to more significant repairs in the future. Contractors prefer to remove the old layer to fully assess and repair any damage, ensuring the longevity and safety of your roof.
When adding a new layer of shingles on top of an existing one, the additional weight on the structure of your home becomes a significant concern. Many older homes are not designed to support the weight of two layers of roofing materials. This added stress can lead to structural compromises and, in severe cases, roof collapse. For this reason, conscientious contractors will often advise against roof-overs to protect the integrity of your home.
Another critical aspect to consider is the manufacturer’s warranty for the roofing materials. Many manufacturers will void the warranty if shingles are installed over an existing layer. This leaves homeowners in a precarious situation should any issues arise with the newly installed roof. Furthermore, local building codes might restrict or entirely prohibit roof-overs. Roofing contractors are well-versed in these regulations and will guide homeowners toward solutions that are not only compliant but also offer the security of a valid warranty.
While a roof-over might appear more cost-effective in the short term, the long-term expenses can be significantly higher. Potential issues hidden by the existing layer, such as leaks or structural damages, can cause extensive damage over time. This makes the initial savings less appealing when compared to the potential future costs of repairs or a premature full replacement. Roofing professionals advocate for full replacements, viewing them as a more economically viable option in the long run, ensuring homeowners get the most out of their investment.
The choice to opt for a roof-over instead of a full replacement might be tempting for homeowners looking to save time and money.
