Replacing old shingles with new ones might seem like a budget-friendly option for homeowners, but it has several drawbacks that every homeowner must be aware of. As experienced roofers, we at G. Keith Roofing and Waterproofing advise against this practice. We suggest that homeowners struggling with roofing problems must either get professional roof repair in Staten Island, NY, or a complete roof replacement service. The potential drawbacks of installing new shingles over old ones include:
Masking the Existing Damage
Several reasons can affect your roof over the years, including trapped moisture, incorrect installation of the existing roof, or poor ventilation, to name a few. These existing issues are often hard to identify from the exterior, therefore requiring a thorough roof inspection. But here lies the problem: when you decide to overlay existing shingles with new ones, the trapped moisture continues to damage your roof. So, while your roof needs replacement, you end up aggravating the problem by masking the existing damage.
Decreasing the Lifespan of New Roofs
During hot weather conditions, heat negatively impacts the multiple layers of asphalt shingles. Heat often gets trapped in the layers, causing shingles to crack or warp, reducing the lifespan of the newly installed shingles layer. Also, it’s not just about the lifespan but also the structural integrity. Through the cracks formed, moisture seeps into the roof, causing severe damage and increasing the risk of roof leakage.
Adds Extra Weight on the Roof
Another major drawback of adding a new layer of shingles over existing ones is the increased weight of the roof. Excessive weight of the roof leads to structural issues and also causes strain on the building’s frame and deck. To prevent the collapse of the roof, you require the installation of a robust support system, adding to the cost of roof installation. Moreover, if you witness snowfall in your area, you have to be extra careful, as the weight of snow can aggravate the problem and increase the risk of damage.
So, these are some of the major drawbacks of directly installing shingle roofs over the existing ones. To prevent aggravating the problem, hire a team for a professional roof inspection and roof replacement service. With quality roof replacement and repairs, you can ensure the longevity of roofs and maintain the structural integrity of the building.
