For many homeowners considering a new metal roof, one of the first questions is whether the new roofing system can be installed directly over the existing shingles. The answer is often yes—but it depends on the condition of your current roof, local building codes, and the specific roofing system being installed.
At Marquis Roofing, we help homeowners throughout New Hampshire evaluate their options and determine the best approach for long-term performance and protection.
Is Installing a Metal Roof Over Shingles Possible?
In many cases, a metal roof can be installed over an existing asphalt shingle roof without a complete tear-off. This can reduce labor costs, shorten installation time, and minimize disruption to your property.
However, every home is different. Before recommending this approach, our team performs a thorough roof inspection to evaluate the condition of the existing roofing system and roof deck.
If the current shingles are laying flat and the roof structure is in good condition, installing a metal roof over shingles may be a viable option.
When Is a Tear-Off the Better Choice?
While overlay installations are possible, there are situations where removing the existing roof is the better long-term solution.
A full tear-off may be recommended if:
The roof deck shows signs of damage or rot
Multiple layers of shingles are already present
Existing shingles are severely curled or deteriorated
Structural concerns need to be addressed
Ventilation improvements are needed
Removing the existing roofing material allows our team to inspect the roof deck, identify hidden issues, and ensure the new roofing system starts with a solid foundation.
