Define the problem before comparing solutions
Ask where water enters or which condition is failing, how that was established and whether surrounding areas were reviewed. Several interior stains can share one source, while a single visible leak can involve concealed damage. A stain count or roof age is not a complete diagnosis.
When the source remains uncertain, a focused investigation may be the next decision. Request the evidence needed to distinguish roof covering, flashing, equipment and other building conditions.
Ask what a repair will achieve
A repair proposal should identify the location, compatible materials, associated details and any limits on the work. Ask whether it addresses only an immediate leak, corrects the cause, or prepares the property for later renewal.
If nearby material cannot be tied into reliably, ask the contractor to explain that finding. The practical extent of a repair depends on the existing system and condition, not an arbitrary percentage of roof area.
Compare the other options when they are suitable
Restoration, recover and replacement are different scopes. A coating relies on an acceptable existing substrate. A recover places a new assembly over selected existing materials. Replacement can expose concealed conditions and remove materials that should not remain.
GAF’s recover guidance makes existing-roof suitability part of the decision. Ask what testing or review supports leaving material in place and what defects must be corrected first.
Get an itemized recommendation
Ask each option to state the assumed conditions, work included, exclusions, maintenance implications and any additional investigation. Include drainage, deck and equipment corrections where relevant.
- What evidence supports this extent of work?
- What problem would remain after the proposed repair?
- What could change the scope once concealed conditions are exposed?
- How will the work fit planned equipment or building changes?
- What written warranty, if any, applies to this exact work?
Keep insurance and technical necessity separate
If a claim is involved, the construction recommendation and the insurer’s coverage decision still answer different questions. Decide on the appropriate work from its technical basis, then reconcile authorizations and payment responsibilities before permanent work begins.
