Flower Mound requires a permit for roof replacement.

Agree who will complete the application and confirm the arrangement with Building Inspections. The Town's homeowner wording does not establish that only the owner may apply or that the permit must be in the owner's name.

Keep it, and keep whatever inspection result comes back with it, in the same file as the photographs and the product records. Keep the permit number, approved scope and any completion records so the work can be traced later. That is exactly the kind of document that turns out to be useful years later, when the contractor is no longer reachable and the next owner is asking what was actually done to the roof.

Sometimes, and it should be a stated choice rather than a default in either direction. Replacing one plane is legitimate where the rest of the roof genuinely has life left, and the constraint is matching: new material against a covering that has been fading for years will read as new, particularly on anything anybody looks at. On a greenbelt-backed house the failing side is usually the one nobody sees from the street, which is what makes the option worth raising here.

Coverage is confirmed against your specific address before anything is scheduled, rather than assumed from a list of place names. Ask and you will get a straight answer either way.
