        "text": "While it's technically possible in some cases, installing new shingles over existing ones (known as a 're-roof' or 'overlay') is generally not recommended as a long-term solution. Most building codes permit only one or two layers of shingles. This approach can hide underlying damage, add excessive weight to your roof structure, and void new shingle warranties. Removing the old roof allows for a thorough inspection of the decking and proper installation of new underlayment, resulting in a more durable and reliable roof system. A full tear-off is almost always the superior choice for longevity and performance.",
