Clear answer
Clear answer, explained.
This includes reviewing roof construction, load capacity, attachment methods, wind uplift resistance, and snow load compliance. A structural engineer may be required to confirm suitability and issue sign-off before installation.
Key points
What this means in practice.
- Roof must support added dead load from panels and racking
- Wind uplift and snow load requirements must meet building codes
- Roof framing, deck type, and attachment points are assessed
- Flat and low-slope roofs may use ballasted or mechanically attached systems
- Structural engineer review is commonly required
- Any required reinforcements must be completed before installation
When this applies
Best-fit environments.
- Commercial buildings considering rooftop solar installation
- Older roofs or buildings with unknown structural documentation
- Flat, low-slope, or large-span commercial roofs
- Projects subject to permitting and engineering approvals
