Structural Engineering On-Site Assessment and Written Report
Structural Engineering Field Inspection and Written Report
Roof Ridge Sagging / Structural Framing Evaluation
This service provides an on-site structural field inspection by a licensed structural engineer retained and coordinated by Turnwood Design Group. It is intended to evaluate visible sagging, deflection, or irregularity along the roof ridge line and determine whether the observed condition appears to be related to the roof framing, supporting walls, foundation movement, past alterations, deterioration, or other structural conditions.
Following the inspection, the structural engineer will provide a written professional engineering report documenting the observed conditions, the apparent structural significance of those conditions, and recommended next steps.
What This Service Includes
On-Site Structural Field Inspection
The structural engineer will visit the property and inspect the accessible portions of the building that may reasonably relate to the reported sagging or deflection of the roof ridge.
The inspection may include review of:
The visible roof ridge and overall roof profile
Areas of apparent sagging, deflection, settlement, or unevenness
Accessible attic and roof-framing conditions
Rafters, roof trusses, ridge boards or ridge beams, collar ties, ceiling joists, and related framing where accessible
Connections between roof-framing members
Bearing walls, beams, posts, and other structural supports beneath the affected roof area
Visible evidence of framing movement, displacement, cracking, deterioration, or failure
Signs of previous structural modifications, repairs, additions, or removal of supporting construction
Accessible foundation and supporting wall conditions where they may contribute to the observed roof movement
Visible evidence of settlement or differential movement within the building
Conditions surrounding chimneys, dormers, additions, or other roof penetrations when relevant
Other readily accessible structural conditions the engineer considers relevant to determining the apparent cause of the ridge-line sagging
The engineer may also review available photographs, inspection reports, building information, renovation history, or contractor observations supplied by the property owner.
Written Structural Engineering Report
Following the field inspection, the structural engineer will prepare a written report addressed to the property owner.
The report will summarize:
The structural conditions observed during the inspection
The location and nature of the apparent roof or ridge-line deflection
The engineer’s professional opinion regarding the apparent cause or contributing factors, when reasonably determinable
The apparent structural significance of the observed conditions
Whether additional investigation appears warranted
Recommended stabilization, repair, reinforcement, monitoring, or further engineering evaluation, as appropriate
Photographs or other supporting documentation considered appropriate by the engineer
Turnwood Design Group will coordinate the engineer’s site visit, provide the engineer with available project information, assist with field coordination, and deliver the completed engineering report to the client.
Site Access Requirements
The client is responsible for providing safe and unobstructed access to the areas necessary for the structural inspection.
This may include access to:
The attic
Upper-floor rooms beneath the affected roof area
Basement or crawlspace areas
Structural support locations beneath the affected portion of the house
The exterior perimeter of the building
Stored materials or other obstructions should be moved where reasonably necessary to allow observation of the structural framing.
If attic access exists, it must be safely accessible at the time of the inspection.
The property owner or an authorized representative familiar with the property should be present during the assessment unless alternative access arrangements have been approved in advance.
Important Limitations
The field inspection is based upon conditions that are visible and reasonably accessible on the date of the inspection.
Unless specifically authorized through a separate written agreement, this service does not include:
Demolition or exploratory openings
Removal of roofing, drywall, plaster, insulation, finishes, or other building materials
Excavation or observation of concealed below-grade construction
Material, soil, or laboratory testing
Land surveying or long-term elevation monitoring
Destructive testing
Structural calculations for a proposed repair
Structural repair drawings or construction documents
Architectural drawings
Building-permit applications
Contractor supervision or construction administration
Inspection or certification of completed repairs
Verification of concealed structural conditions
Additional site visits
Engineering services related to conditions discovered after the inspection
Design of repairs unless specifically added to the scope
The engineer’s report will reflect the engineer’s professional opinion based upon the conditions visible, accessible, and known at the time of the inspection.
Roof framing and other structural components are frequently concealed behind finishes, roofing materials, insulation, or other construction. Conditions that cannot be observed may affect the engineer’s conclusions and may require additional investigation.
If the engineer determines that exploratory openings, structural calculations, monitoring, repair design, or additional engineering work are necessary, those services can be discussed separately.
The written report does not guarantee acceptance by a buyer, seller, lender, insurance company, municipality, building official, home inspector, contractor, or other third party. Any additional documentation or engineering services requested by a third party will be considered separately.
Scheduling and Payment
The professional fee for this service is $2482.00
Payment in full is required in advance. The field inspection is not reserved until payment has been received and the engineer’s availability has been confirmed.
Because this service requires the retention and coordination of a licensed structural engineer, payment becomes non-refundable once the engineer has been retained or the site inspection has been scheduled.
Client-requested rescheduling is subject to the engineer’s availability and may involve additional charges if costs are incurred.
The written report will be issued following completion of the field inspection and the engineer’s professional review.
Any services requested beyond the scope described above will require separate written authorization and may involve an additional professional fee.
By completing this purchase, the client acknowledges and accepts the scope of services, site-access requirements, limitations, scheduling terms, and payment conditions described above.
Terms and Conditions
Structural Engineering On-Site Assessment and Written Report
These Terms and Conditions (“Agreement”) govern the structural engineering assessment and written report purchased through this private online checkout page.
“Turnwood” means Turnwood Design Group LC. “Client” means the person or entity purchasing the Services. “Engineer” means the independently licensed professional engineer retained by Turnwood to perform the engineering portion of the Services. “Property” means the property identified by the Client during checkout or subsequent written correspondence.
By completing this purchase, the Client confirms that the Client has read, understood, and accepted this Agreement in its entirety.
1. Services
Turnwood will retain and coordinate an appropriately licensed professional engineer to perform a limited, visual, non-destructive assessment of accessible conditions associated with the reported brick-veneer separation or movement at the Property.
The Services include:
One on-site visit by the Engineer.
Visual observation of readily visible and safely accessible affected areas.
Review of visible brick-veneer displacement, cracking, separation, or movement.
Visual observation of accessible adjacent wall and foundation conditions.
Consideration of available information concerning proposed helical-pier work.
Photographic documentation as the Engineer considers appropriate.
One written report prepared by the Engineer.
Delivery of the completed report electronically to the Client.
Turnwood will coordinate scheduling, transmit available information to the Engineer, and deliver the completed report. The Engineer retains exclusive control over all professional engineering opinions, conclusions, recommendations, calculations, and determinations.
2. Professional Engineer
The engineering assessment and report will be performed and prepared by a professional engineer licensed in the jurisdiction where the Property is located.
Turnwood is retaining the Engineer as an independent professional consultant. The Engineer is not represented as an employee, partner, or agent of Turnwood.
Turnwood will not direct, alter, override, or guarantee the Engineer’s professional judgment. No preliminary discussion, estimate, photograph, text message, or statement made before issuance of the report constitutes a final engineering opinion.
The report will be signed or otherwise authenticated by the Engineer. It will be sealed only when required by applicable law, required by the agreed scope, or considered appropriate by the Engineer. A governmental submission, permit package, or sealed repair design is not included unless expressly stated in writing.
3. Limited Nature of Assessment
The Services constitute a limited visual assessment and are not a comprehensive structural inspection of the entire building.
The Engineer will observe only conditions that are:
Visible at the time of the visit;
Reasonably and safely accessible;
Within the stated area of concern; and
Relevant to the limited purpose of the engagement.
The assessment does not include demolition, removal of finishes, excavation, probing, invasive testing, destructive investigation, laboratory testing, soil testing, surveying, monitoring, or opening concealed construction.
The absence of a comment about a particular component does not constitute a determination that the component is safe, code-compliant, properly constructed, or free from defects.
4. Concealed and Unknown Conditions
Structural conditions may be concealed by brick, siding, drywall, framing, insulation, soil, landscaping, finishes, furnishings, decking, planters, or previous repairs.
Neither Turnwood nor the Engineer is responsible for failing to identify a condition that was concealed, inaccessible, undocumented, misrepresented, altered, or not reasonably discoverable during the limited visual assessment.
If concealed or materially different conditions are later discovered, the opinions and recommendations in the report may require modification. Additional investigation, calculations, site visits, or documents will constitute additional services and require separate written authorization and payment.
5. Client Responsibilities
The Client shall:
Provide the correct Property address and contact information.
Disclose all known structural movement, cracking, repairs, water intrusion, foundation work, insurance claims, reports, permits, and contractor recommendations relevant to the affected area.
Provide available drawings, photographs, proposals, and prior reports before the site visit.
Provide lawful access to the Property at the scheduled time.
Ensure that an owner or authorized adult representative is present unless alternative access has been approved in writing.
Remove planters, stored materials, decking components, vegetation, or other obstructions that prevent access to the affected wall and foundation.
Provide a reasonably safe working environment.
Restrain animals and disclose known hazards.
Obtain any required permission from owners, tenants, condominium associations, or other interested parties.
Turnwood and the Engineer may refuse to enter or inspect an area considered unsafe, obstructed, unsanitary, structurally unstable, or outside the agreed scope. Such refusal will not constitute a breach of this Agreement.
6. No Emergency or Life-Safety Service
The Services are not emergency-response services and are not intended to determine whether immediate occupancy is safe.
Brick veneer that is separating from a wall may present a falling-material hazard. Until the condition has been evaluated and appropriately stabilized, the Client is responsible for restricting access to the affected area and taking reasonable precautions to protect occupants, visitors, workers, vehicles, and neighboring property.
If active movement, falling masonry, imminent collapse, or another immediate danger is suspected, the Client should vacate the affected area and contact emergency services, the local building authority, and an appropriately qualified stabilization contractor. Purchasing this service does not transfer responsibility for site safety to Turnwood or the Engineer.
7. Services Not Included
Unless expressly added through a separately signed written agreement, the following are excluded:
A whole-building structural inspection.
Destructive or invasive investigation.
Demolition or reconstruction.
Soil borings, geotechnical engineering, or laboratory testing.
Property-line, elevation, or topographic surveying.
Continuous movement monitoring.
Structural calculations for a repair design.
Design of helical piers, foundations, walls, anchors, ties, lintels, or masonry repairs.
Construction drawings, specifications, or permit documents.
Architectural design.
Contractor selection or bidding.
Construction means, methods, sequences, procedures, or safety precautions.
Supervision or control of any contractor.
Review or approval of shop drawings or contractor submittals.
Inspection or certification of completed construction.
Verification that repairs comply with the Engineer’s recommendations.
Municipal, lender, insurer, purchaser, or court testimony.
Expert-witness services, depositions, mediation, arbitration, or litigation support.
Additional meetings, site visits, revised reports, or responses to third-party questions.
8. No Warranty or Guarantee
Professional services will be performed using the ordinary degree of skill and care normally exercised by similarly situated professionals performing comparable services under similar circumstances.
No other warranty or guarantee, express or implied, is made.
Neither Turnwood nor the Engineer guarantees:
The discovery of every defect or cause of movement;
That observed conditions will remain unchanged;
That a recommended repair will fall within a particular budget;
That a contractor’s proposed work is adequate;
That a property transaction will close;
That the Property is marketable, insurable, financeable, or code-compliant;
That a municipality, lender, insurer, buyer, contractor, or other party will accept the report; or
That no additional repairs, investigation, or professional services will be required.
The report is a professional opinion based on limited observations and information available on the date of the assessment. It is not a warranty, insurance policy, certification of structural soundness, or guarantee against future movement or failure.
9. Reliance and Third-Party Use
The report is prepared solely for the Client and solely for the purpose described in this Agreement.
No buyer, lender, insurer, municipality, contractor, tenant, real-estate professional, or other third party may rely upon the report without the Engineer’s prior written authorization.
The Client may provide a copy of the report to another party for informational purposes, but doing so does not create a professional relationship, duty, or liability to that party.
If the Client requires the report to be addressed to, relied upon by, assigned to, or revised for a third party, the request must be made before the site visit. Additional review, contractual terms, insurance requirements, reliance letters, or fees may apply.
The Client shall not alter, excerpt, reformat, remove qualifications from, or present portions of the report in a misleading manner. The report must be distributed in its complete form.
10. Fee and Advance Payment
The fixed fee for the stated Services is provided above.
Payment in full is required before the Engineer is retained, project materials are reviewed, or the site visit is reserved. No appointment is confirmed until Turnwood has received cleared payment and issued written scheduling confirmation.
The fixed fee is based on the scope and conditions described in this Agreement. Additional services are not included and will not be performed without written authorization, except for actions reasonably necessary to address an immediate life-safety concern observed during the visit.
11. Cancellation and Refunds
Any cancellation right required by applicable law remains unaffected.
Subject to any non-waivable statutory cancellation right:
The Client may cancel before Turnwood has retained the Engineer, reviewed project materials, or reserved the site visit.
Once professional work has commenced, Turnwood may retain the portion of the payment attributable to services performed, administrative time incurred, consultant commitments made, and nonrecoverable expenses.
Once the Engineer has been retained or the appointment has been reserved, amounts committed to the Engineer are non-refundable.
Once the site visit has occurred, the fee is earned and non-refundable.
Once the report has been delivered, no refund will be issued based on dissatisfaction with the Engineer’s findings, conclusions, recommendations, repair implications, or a third party’s response to the report.
A request for a particular result does not obligate the Engineer to reach that result. An unfavorable engineering opinion is not grounds for a refund.
12. Rescheduling, Access Failure, and Missed Appointments
Requests to reschedule must be received in writing at least two business days before the confirmed visit.
Rescheduling remains subject to the Engineer’s availability. The Client is responsible for any fee charged by the Engineer because of cancellation, delay, or rescheduling.
If the Engineer cannot gain access, the required representative is absent, obstructions have not been removed, or the site is unsafe, the visit may be terminated and treated as a missed appointment. A return visit will constitute an additional service and require payment of an additional fee before scheduling.
Turnwood and the Engineer are not liable for delays caused by weather, illness, emergency conditions, travel disruption, unsafe conditions, incomplete information, delayed access, governmental action, or other events beyond their reasonable control.
13. Report Delivery
The report will be delivered electronically after the site visit and completion of the Engineer’s professional review.
Any delivery estimate is an estimate rather than a guaranteed deadline unless Turnwood expressly agrees to a deadline in writing.
The Engineer may request additional information or recommend further investigation before issuing a final opinion. A reasonable delay required to complete the professional review does not constitute a breach or entitle the Client to a refund.
14. Additional Services and Changed Scope
Conditions encountered at the Property may require services beyond those reasonably anticipated when this Agreement was accepted.
Additional services may include:
Further site visits;
Review of newly produced documents;
Destructive investigation;
Structural calculations;
Repair design;
Construction documents;
Contractor coordination;
Responses to governmental or third-party comments;
Review of completed repairs; or
Testimony or dispute-related services.
Additional services require a separate written proposal or written authorization and will be billed separately. The Client is not obligated to purchase additional services from Turnwood or the Engineer.
15. Contractor Responsibility
Neither Turnwood nor the Engineer is responsible for a contractor’s work, pricing, scheduling, workmanship, materials, means and methods, sequencing, site safety, temporary support, or compliance with laws and permit requirements.
Reviewing a contractor’s proposal does not constitute approval, supervision, control, or acceptance of the contractor’s work.
Contractors remain solely responsible for field verification, temporary stabilization, safe performance of construction, compliance with the contract documents, and notifying the Engineer of conflicts or materially different conditions before proceeding.
16. Ownership and Permitted Use
The Engineer retains ownership of the report, photographs, calculations, notes, and other instruments of professional service, subject to the Client’s limited right to use the final report for the Property and stated purpose.
Payment grants the Client a nonexclusive license to use the final report for the stated purpose. The Client may not reuse the report for another property, another structure, a materially altered condition, or an unrelated project.
Preliminary notes, internal communications, draft reports, field notes, and working documents are not deliverables unless expressly identified otherwise.
17. Photographs and Documentation
The Client authorizes Turnwood and the Engineer to photograph and document accessible areas of the Property for professional evaluation, recordkeeping, insurance, and report preparation.
No personally identifying project information or recognizable images of the Property will be used publicly for marketing without the Client’s separate permission, except as reasonably required by law, professional standards, insurance reporting, dispute resolution, or defense of a claim.
18. Limitation of Liability
To the fullest extent permitted by law, Turnwood’s aggregate liability arising from its coordination, administration, scheduling, communication, or other non-engineering services under this Agreement shall not exceed the amount actually paid to Turnwood under this Agreement.
Turnwood is not responsible for independent professional opinions rendered by the Engineer or for construction performed by contractors or other third parties.
Nothing in this Agreement waives or limits a liability that cannot lawfully be waived or limited. The Engineer’s professional liability, if any, remains subject to applicable law and any separate terms issued by the Engineer.
The Client agrees that the fee reflects the allocation of risk stated in this Agreement. If the Client requests a higher contractual liability limit, Turnwood may consider that request before services begin in exchange for an additional fee and revised written agreement.
19. Waiver of Consequential Damages
To the fullest extent permitted by law, the Client and Turnwood waive claims against each other for indirect, incidental, special, exemplary, punitive, or consequential damages arising from this Agreement.
This waiver includes, without limitation, alleged lost profits, lost sale proceeds, loss of financing, diminution in property value, loss of use, relocation expenses, delay damages, emotional distress, and losses arising from a third party’s refusal to accept the report.
This provision does not waive any remedy that applicable law prohibits the parties from waiving.
20. Claims Notice and Opportunity to Address
The Client shall notify Turnwood in writing of any claimed error, omission, or breach promptly after discovery and before altering, concealing, demolishing, or repairing the condition involved, except when immediate action is reasonably necessary to protect life or property.
The notice must describe the claimed issue and include relevant photographs, reports, and communications.
To the extent reasonably possible, the Client shall provide Turnwood and the Engineer an opportunity to review the claimed condition before corrective work begins. Failure to provide notice and a reasonable opportunity to review will bar recovery to the extent the failure materially prejudices the ability to investigate or mitigate the claim.
21. Dispute Resolution
The parties shall first attempt in good faith to resolve any dispute through direct written communication.
If the dispute is not resolved within 30 days after written notice, the parties agree to participate in non-binding mediation before filing a civil action, unless emergency injunctive relief is reasonably necessary or a statutory filing deadline would expire.
Mediation will take place in Oakland County, Michigan, unless the parties agree otherwise. The parties will share the mediator’s fee equally and bear their own legal and professional expenses.
If mediation does not resolve the dispute, either party may pursue available remedies in a court of competent jurisdiction.
Nothing in this section eliminates a Client’s right to pursue a remedy that cannot legally be conditioned on mediation.
22. Governing Law and Venue
This Agreement is governed by the laws of the State of Michigan, without regard to conflict-of-law principles.
Subject to the dispute-resolution provision above, any legal proceeding arising from this Agreement shall be brought in a court of competent jurisdiction located in the Michigan county where Turnwood’s principal office is located, unless applicable law requires another venue.
23. Electronic Agreement and Communications
The Client agrees that:
Electronic acceptance has the same effect as a handwritten signature.
Checkout records, payment records, emails, and electronic communications may be retained as evidence of the Agreement.
Notices and project communications may be delivered electronically to the email address or telephone number provided by the Client.
The Client is responsible for maintaining accurate contact information and reviewing communications concerning the Services.

Is at least 18 years old;
Has authority to order the Services;
Owns the Property or has the owner’s authorization;
Has authority to grant site access; and
Has provided accurate and complete information.
If the Client is acting for another person or entity, the Client represents that the Client has authority to bind that person or entity to this Agreement.
25. Compliance With Law
Nothing in this Agreement requires Turnwood or the Engineer to violate a law, code, licensing requirement, ethical obligation, or professional standard.
If a provision conflicts with a non-waivable legal requirement, the legal requirement will control, and the remaining provisions will continue in effect.
26. Severability
If any provision of this Agreement is found invalid or unenforceable, that provision will be enforced to the maximum extent legally permitted or severed if necessary. The remaining provisions will remain in effect.
27. No Waiver
A party’s failure to enforce a provision on one occasion does not waive the right to enforce that provision later. A waiver is effective only when made in writing by the party granting it.
28. Assignment
The Client may not assign this Agreement, the report, or any claim arising from the Services without Turnwood’s prior written consent.
Turnwood may retain and coordinate qualified consultants as reasonably necessary to perform the Services.
29. Entire Agreement and Order of Precedence
This Agreement, the product description, the confirmed project address, and any written scope modification accepted by Turnwood constitute the entire agreement concerning the Services.
They replace prior discussions, advertisements, text messages, emails, representations, and understandings concerning the same Services.
