California Residential Inspector Practice Exam

True or False: A roof recover over an existing roof is permitted if one or more roof coverings are already applied.

1. Correct

2. Incorrect

3. Depends on local codes

4. Not specified

The correct answer is: Incorrect

In California, the building codes generally allow for a roof recover over an existing roof, but there are specific conditions that must be met. When there is already an existing roof covering, local codes typically specify that you can only recover a roof that has one existing layer. If there are two or more existing layers, then a complete tear-off of the old roofing material is usually required before applying a new cover. The scenario where it may depend on local codes emphasizes the importance of checking with local building authorities, as regulations may vary by jurisdiction. However, the indication that recovering over an existing roof is not permitted if one or more roof coverings are already applied aligns with the idea that maintaining the structural integrity and understanding the load-bearing capacity of the roof is crucial. Therefore, such a situation may lead to complications that local codes specifically seek to mitigate. Understanding these regulations is important for ensuring compliance with building standards and maintaining safety and functionality in residential construction.
