Roof structural engineering for solar, equipment, and framing changes
Before installing solar, rooftop equipment, or altered framing, confirm the roof capacity and get the reinforcement or attachment design the project requires.
- Check the existing framing
- Define the added demand
- Detail what must change
Verify
Existing framing
Review member sizes, spans, layout, condition, and available documents.
Calculate
Added demand
Consider equipment, solar, framing changes, and applicable environmental loads.
Detail
Required strengthening
Define reinforcement, support, or attachment work when analysis indicates it is needed.
Start here
What is changing at the roof?
The intended use and loading determine the right assessment or design scope.
Start the conversation
Review my roof project
Tell us what is changing and share available roof, framing, and product information so we can define the appropriate review.
What to send now
- Property location and the planned roof change
- Roof or attic photos and available framing plans
- Product or equipment weight, dimensions, and support information
- Proposed equipment, solar, opening, or framing location
Service scope
What we check
The roof framing and the structure supporting it both matter.
- Accessible or documented rafters, trusses, joists, beams, posts, bearing, and connections
- Existing and proposed loads from roofing, equipment, solar, wind, and seismic demands
- How concentrated equipment or attachment loads spread through the framing
- Reinforcement, new supports, curbs, attachments, and connections when required
Project deliverables
Deliverables matched to your project
The package is matched to an evaluation, installation, repair, or new design.
- A capacity assessment based on the stated framing, spans, and loads
- Structural calculations for the proposed change
- Reinforcement, support, curb, framing, and attachment details as required
- Permit documents and field-verification notes when included
A clear path forward
Confirm the roof before installation
- 01Step Step 01
Send the roof and product information
Share plans, framing photos, equipment or solar data, dimensions, and the intended change.
- 02Step Step 02
Check capacity and design changes
We review loads, supports, and connections, then develop required modifications.
- 03Step Step 03
Give the team clear direction
Use the agreed engineering package for permit review and installation.
Why NBE
Avoid designing from equipment weight alone
Placement, member capacity, bearing, connections, and support below all affect the answer.
Analysis tied to documented equipment and mounting information
Clear separation of structural and weatherproofing responsibilities
Reinforcement options when the existing roof is not adequate
Assumptions and field checks stated for the project team
Clear communication from the first question to the next step
“They were very responsive, helped me salvage what I could from the previous firm, and provided the expertise and knowledge needed to finish the job quickly and efficiently.”
Frequently asked questions
Do solar panels always require structural review?+
Requirements vary by roof, system, and jurisdiction. Review can confirm whether existing framing and attachments are appropriate for the proposed loads and layout.
What do you need for a rooftop equipment analysis?+
Useful inputs include equipment weight and dimensions, support or curb information, proposed location, roof framing plans, field measurements, and photos.
Can you engineer reinforcement if the roof is not adequate?+
Yes. When feasible, we can design strengthening, load distribution, added supports, or revised placement based on the confirmed conditions.
Does roof engineering include waterproofing?+
Our scope is structural. Waterproofing and roofing details should be coordinated with the roofer, manufacturer, architect, or other responsible project professional.
Can you evaluate damaged or sagging framing?+
Yes. An assessment can document visible conditions and determine whether further investigation, temporary measures, repair design, or replacement should be considered.
Can roof trusses be cut or altered for ducts, skylights, or equipment?+
Do not alter a truss without an approved design. The appropriate repair or modification depends on the truss layout, loading, proposed opening, and manufacturer information when available.
Check the roof before ordering or installing
Send the property location, roof information, photos, and proposed equipment or modification so we can define the review.
