What does the term "re-roofing" refer to in construction?

The term "re-roofing" specifically refers to the process of adding new roofing materials over an existing roof. This method is often chosen to save time and reduce costs since it avoids the labor-intensive process of completely removing the old roof. By overlaying new roofing materials, such as shingles, on top of the existing structure, contractors can enhance the roof's aesthetics and increase its durability, as long as the underlying roof is in reasonable condition.

In the context of roofing practices, re-roofing can be a practical option when the roof has minor issues that do not warrant a full replacement. However, there are guidelines and local codes that often limit the number of layers that can be applied in this manner, which is something contractors must be aware of.
