For Contractors
Structural Engineering Support for Your Rooftop Equipment Project
Built for HVAC contractors, general contractors, roofers, architects, permit coordinators, and installation managers. Submit multiple equipment units per project, keep existing and proposed equipment separate, and upload spec sheets and correction letters.
Preparation checklist
Keep the form usable even when some information is unavailable — "Unknown" is acceptable.
- Project address
- Existing and proposed equipment specifications
- Operating weights, if available
- Roof and equipment photographs
- Existing structural drawings, if available
- Proposed unit location and support details
- Curb or adapter information
- Permit correction notice, if applicable
What the contractor intake includes
- • Company and project-manager information
- • Multiple equipment units per project
- • Separate existing and proposed equipment fields
- • Specification-sheet and correction-letter uploads
- • Installation deadline and permitting status
- • Ability to submit another property without overwriting earlier projects
- • Clear next steps after submission
Each property is tracked as a separate project. Submit a new intake for each property so repeat submissions stay separate.
