Can I put more than one layer of asphalt shingles on my roof?

Answer: In some cases
Explanation: It is sometimes possible to install a second layer of asphalt shingles over an existing single layer, but it depends on local building codes and the condition of the current roof. Some jurisdictions allow a maximum of two total layers, while others require a full tear-off before re-roofing. Adding a second layer can save on removal costs, but it may also add extra weight and can hide underlying issues with the roof deck. For these reasons, it is only recommended when the existing roof is in good condition and allowed by code.
