Understand the system
Coordinate the roof and future rooftop equipment before work starts. Panel compatibility, access and attachment details cross trade boundaries.
What to discuss
Tell the roofing contractor and solar designer whether solar is planned now or later. Identify the roof product and ask both parties how the proposed attachment and access arrangement fits its documentation.
Build a clear scope
Confirm who is responsible for roof interfaces, electrical work and future servicing. Avoid assuming that every standing seam can use the same clamp or that a later installation leaves every warranty unchanged.
Before selecting a contractor
Request the product documentation, a relevant scope, evidence of applicable qualifications and current coverage, and references you can check. Installation methods and warranty terms must be confirmed for the proposed project.
