Same builder, same era, different roofs
Houses built the same year still differ in exposure, tree cover, ventilation, and past repairs. A neighbour's failed underlayment is a reason to look at yours, not evidence that yours has failed.
Ask what was documented on your roof
The useful question is always the same: show me the condition on my roof, in photos, and connect each photo to a line in the scope. A general statement about the neighbourhood is not a finding.
Neighbourhood pricing can be genuine
Crews already on the street really do have lower mobilisation costs. Accept the discount; just do not accept the deadline that often comes attached to it.
Underlayment first on tile homes
Most of these roofs are concrete tile. If yours is, the likely honest scope is lift-and-relay with new underlayment rather than all-new tile. Get both priced.
