Homeowners often explore various options for roof maintenance and repair, such as roof-overs. This practice involves installing a new layer of shingles over the existing roof. It’s mainly considered due to its perceived cost-effectiveness and faster completion. However, your roofing contractor might advise against this method for several reasons. Continue reading to learn about the drawbacks of a roof-over.
One of the primary concerns with roof-overs is that they can mask underlying problems. Roofs can have hidden damage or deterioration that isn’t visible from the surface. When a new layer of shingles is laid over an existing one, issues such as rot, mold, or structural weaknesses remain unaddressed. This can lead to more significant and costly repairs as these problems worsen.
The integrity of your roof is paramount to ensuring the safety and security of your home. A roof repair and replacement focusing on removing the old materials allows for a thorough inspection of the decking and structure. These inspections are crucial for identifying any areas that need repair or reinforcement. By opting for a roof-over, homeowners might inadvertently compromise the structural integrity of their roofs. The additional weight of a second layer of shingles can also strain the roof’s structure, potentially leading to sagging or collapse in extreme cases.
Another significant downside to roof-overs is the risk of a shortened roof lifespan. Proper ventilation is a critical aspect of a healthy roof system. Unfortunately, roof-overs can often lead to inadequate ventilation, trapping heat and moisture. These conditions are likely to accelerate the aging process of the roofing materials, leading to a roof that may need replacement sooner than expected.
Many roofing manufacturers do not honor warranties for materials installed over existing shingles, citing the increased risk of premature failure. Additionally, local building codes may restrict or limit roof-overs. Ensuring compliance with these codes is crucial; failing to do so can result in fines or other penalties.
When considering updates to your home, it’s vital to consider how they will impact its value and appeal. A new roof and gutters can significantly enhance a home’s exterior. However, a roof-over might detract from this. The added layer can affect the roof’s appearance, making it look bulky or uneven. For homeowners thinking about the future sale of their property, a full roof replacement is more likely to be viewed favorably by prospective buyers than a roof-over.
