Remove the old shingle covering
The city calls for complete removal of existing shingles and new underlayment for a shingle reroof. A second covering over the old shingles is not the approach described in that guidance.

Mansfield treats shingle-only residential reroofing differently from work on decking or structure. Commercial reroofing has its own permit requirement. Understand the scope before the project starts.
The city’s published roofing FAQ says replacing shingles alone on a one- or two-family dwelling does not require a permit. Work involving decking or structural elements changes that distinction. Commercial reroofing requires a permit.
Permit exemption does not mean the roofing can be installed without applicable standards. The property, the building type and the actual work need to be clear before relying on the shingle-only exception.

Good-condition sheathing does not automatically need replacement. Deteriorated or unsuitable areas need to be addressed before the new roof covers them.
The city identifies energy-code requirements when insulation is removed during commercial reroofing. That can affect the assembly and should be resolved in the scope.
Start with Mansfield Building Safety’s roofing answers and the city’s current Building Safety FAQ directory. Describe the building type and whether the work reaches below the roof covering.
A neighborhood material approval is a separate matter from the city’s permit process. If an association governs exterior changes at the property, confirm its current requirements before selecting a visible material change.
The linked city page includes code references. Confirm the applicable current requirements with the city instead of assuming an older citation applies unchanged to every new project.
