The short answer
If your roof covering is near the end of its life, replace it before the array goes on. Panel warranties can run 25 years, so a roof that fails under the array adds a removal and reinstall bill to the roofing bill. Doing both together avoids that second bill.
What should you know first about solar and Roof Replacement?
From a roofer, not from a sales visit.
Deck damage shows only once the old roof is off.
Agree the order and the dates in writing before either starts.
Shingle warranties can exclude flashings, so the mounts rest on the installer’s workmanship warranty.
Why does replacing the roof first cost less?
Replacing the roof first costs the price of a roof.
Replacing it in eight years costs a roof plus removing, storing and reinstalling the array, new flashings and attachments, and the production lost while it is off. Removal and reinstall covers that job.
No version of waiting is cheaper. The only question is whether the roof has real life left.
How do you judge remaining roof life?
Roof age is a starting point, not an answer. Condition decides it, and a roofer should put that in writing.

, which shows only once something is lifted.
anywhere in the roof structure.
How do you sequence two trades?
The roof goes on first, then the array. What goes wrong is the gap between them.
A roofer finishing late or a solar crew booked weeks out leaves you chasing two companies that do not work for each other. Fix it in the contracts: agreed dates, an agreed handover, and one named person responsible for the join.
If one company does both, that problem largely disappears, which is much of the value of a combined provider.
Who pays if the roof leaks at a mount?
A leak near a solar attachment can leave two companies pointing at each other, with you in the middle.
The GAF shingle warranty we read excludes flashings and metal work, so the waterproofing at a solar mount rests on the installer’s workmanship warranty. Ask both companies, in writing, who investigates and who pays if water comes through.

We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
