Special Considerations
HOA Rules
HOA Rules: If in a homeowners association, secure HOA approval first or alongside borough permits.
They may restrict shingle types, colors, or vent placements.
Zoning
Zoning Checks: Ensure your roof complies with height, pitch, and material zoning rules.
Commercial zones may have stricter fire ratings or drainage requirements.
Historic Properties
Historic Districts: Derry has few, but if your property qualifies, expect extra review for visible changes.
Preserve original features—check with local historic resources.
