- ✓ Plan for weather delays—inspections can't happen in rain, and Gaithersburg winters can slow things.
- ✓ Document before/after photos and receipts for insurance and future sales.
- ✓ Check for incentives: Some energy-efficient roofs qualify for rebates—ask about green building programs.
- ✓ Insurance note: Unpermitted work can void homeowner's policies during storms.
Special Considerations
HOA Rules
HOA Rules: Many Gaithersburg neighborhoods have HOAs. Get written approval first—they often require specific materials, colors, or architect review before city permits.
Zoning
Zoning Checks: Ensure your roofing complies with residential/commercial zoning. Commercial projects might need setbacks or use variances—consult planning dept early.
Historic Properties
Historic Districts: If in a designated area like Kentlands, additional reviews from historic preservation boards may apply. Special materials or designs could be mandated.
