Yes, shingle roofing can often be installed over an existing roof, but this decision hinges on several factors. Here are key considerations:

Building Codes: Ensure that your local building codes allow for multiple layers.
Roof Condition: The existing roof must be in good condition without significant damage or leaks.
Weight Concerns: Adding a second layer increases the weight on the structure, which can be a concern for older buildings.
Assessment: A thorough assessment by a professional is recommended to determine if your current roof can handle another layer.
For the best results and to ensure adherence to all relevant codes and considerations, hiring an experienced contractor for Keeney’s professional shingle roof installation is advisable. This ensures that the new shingles are laid properly, which contributes to the longevity and durability of your roof.
