Tips
- Mesa County will not perform on-roof inspections for pitches over 4/12 unless the contractor provides fall-protection equipment; otherwise inspections are visual-only by the best available means.
- Inspections are scheduled in the morning during hot weather where possible, to avoid shingle damage and protect inspector safety.
- The contractor/installer is responsible for providing secure access and a ladder for all roofing inspections.
- Any exception to the Reroof Policy must be approved by the Building Official before work begins.
Frequently asked questions
- Do I need a permit to re-roof my house in Grand Junction?
- It depends. A single-layer overlay with repairs under 100 sq ft does not require a permit. A permit is always required if there are already two or more layers on the roof, if a roof recover isn't approved per code/manufacturer instructions, or for any commercial roofing project.
