The Dilemma: Installing New Shingles Over Old Ones
When faced with the need for a new roof or addressing damaged shingles, homeowners often ponder the idea of re-shingling over the existing ones. While it might seem like a straightforward solution, there are several factors to consider.
The Risks of Layering Shingles
While it’s technically possible to layer new shingles over old ones, it’s not always the best approach. Older shingles, especially those showing signs of wear and tear, are prone to getting blown away in strong winds. This not only poses a risk to the property but can also lead to potential water leaks, causing further damage to the home’s interior. If one opts to go this route, it’s crucial to ensure that the new shingles are of a different make than the original ones to prevent easy tearing or breaking. Additionally, a specialized roofing cement, designed for this very purpose, should be employed.
Why Starting Fresh Often Wins
In many instances, completely removing the old roof proves to be the most beneficial choice. Building regulations typically permit only two layers of roofing materials on a residence. This means that if there’s already a layer of asphalt shingles on the roof, adding another layer might not be compliant with local codes.
Moreover, if the existing shingles are deteriorating or curling, it’s a clear sign that starting afresh is the way to go. While some homeowners might be tempted to save costs by removing the old shingles themselves, if there are underlying issues like leaks pointing to structural problems, it’s wise to engage professionals like Guns N’ Hoses Roofing & Siding.
The Silver Lining: When Layering Makes Sense
There are scenarios where layering new shingles over old ones can be a viable option. For homeowners looking for a quick aesthetic upgrade without the commitment of a full replacement, this method can be both cost-effective and less time-intensive.
If the existing shingles are still in decent condition, they can serve as a foundation for the new layer, potentially extending the life of both sets of shingles. In such cases, incorporating a felt paper underlayment can be beneficial, especially when layering over an asphalt shingle structure, as it aids in leak prevention.
