Tear-Off, Recover, and Re-Roofing
Learn when removal is required, when recovering is permitted, and how deck evaluation drives the decision.
Short answer
Re-roofing questions turn on whether existing coverings may remain. Code limits the number and condition of layers, requires deck evaluation, and prohibits recovering in defined situations such as water-soaked or deteriorated existing roofing.
01
Ask three questions in order
First, what is the existing assembly and its condition? Second, does code permit a recover in this situation? Third, what does the deck evaluation show?
Answering in that order prevents the common error of choosing a method before evaluating the substrate.
02
Recognize situations requiring removal
Code identifies conditions where existing roofing must be removed rather than covered.
- Existing roofing that is water soaked or deteriorated
- Excessive existing layers
- Deck damage requiring repair or replacement
- Assemblies where a recover is not an approved configuration
- Situations where required attachment cannot be achieved
03
Deck evaluation is not optional
Fastener holding power depends on sound decking. Covering a compromised deck transfers a hidden defect into a new assembly.
Re-nailing and deck repair requirements may also apply during re-roofing.
04
The estimating consequence
Tear-off, disposal, and unforeseen deck repair carry real cost. Contracts should address how discovered deck damage is priced and authorized.
That contract language connects this trade topic directly to Business & Finance material on change orders.

Requirements, references, and testing procedures can change. Verify current details with Florida DBPR, the CILB, and the current exam vendor before acting.
Candidate questions
Frequently asked questions
How many layers can remain?
Code limits layers and conditions for recovering. Verify the current provision for the assembly and jurisdiction.
Is a recover cheaper?
Sometimes initially, but it forfeits deck inspection and may not be permitted. Evaluate compliance first.
Who pays for unexpected deck damage?
That should be defined in the contract through a change order provision before work begins.
