Truss Stamp and Engineering Review for Permits
Truss stamp and engineering review for roof and floor truss packages, girders, bearings, uplift and repairs, sealed by a state-licensed PE.
- Stamped by a PE licensed in your state
- Built to IBC, IRC and local amendments
- Plan-check comments answered
Truss drawings checked, coordinated and sealed
Most roofs and many floors today are built with manufactured trusses. The truss supplier designs each truss with software and produces truss design drawings, but that is often not the end of the story at the building department. Many jurisdictions require those drawings to carry a truss stamp from an engineer licensed in the state, and many want the building’s engineer of record to confirm that the trusses work with the rest of the structure.
PE Engineer fills both roles. We review truss packages for homes, garages, barns, additions and commercial buildings, check them against your plans and the loads at your site, coordinate any corrections with the truss supplier, and have the drawings sealed by a PE licensed in the state where the project is located. We also engineer repairs for trusses that were cut, damaged or overloaded in the field.
Contractors use this service to keep a framing schedule moving when a truss submittal stalls in plan review. Truss suppliers use it when a project lands in a state where their own engineer does not hold a license.

What we review and stamp
Our review looks at each truss in the context of the whole building, not just the individual truss sheets.
Roof truss packages
Common, hip, scissor, attic, mono and girder trusses for homes, garages and additions, checked for snow, drift, wind uplift and the actual roofing weight.
Floor trusses
Open-web floor trusses checked for span, live and dead load, deflection and vibration, plus ductwork chases and strongbacks shown on the layout.
Barn and shop trusses
Long-span wood and metal trusses for pole barns, shops and agricultural buildings, including heavier snow loads and purlin or girt connections.
Girder trusses and hangers
Multi-ply girder trusses checked for ply-to-ply fastening, hanger capacity and the concentrated loads they deliver to walls, posts and footings below.
Bearing and uplift
Reactions at every bearing compared to the wall or beam that supports them, with uplift connectors and hold-downs specified to keep the roof attached.
Truss repairs
Engineered repair details for trusses that were cut for attic access, ducts or skylights, damaged in shipping or fire, or overloaded by added equipment.

When truss drawings need a PE stamp
Truss requirements vary widely from one building department to the next. Some accept the supplier’s truss design drawings as delivered. Others require additional review or a seal before they will approve the framing. You will likely need our truss stamp or review when:
- Your jurisdiction requires truss design drawings to be sealed by an engineer licensed in the state, and the supplier’s engineer is not licensed there.
- The plan reviewer asks the engineer of record to review the truss submittal for compatibility with the building design.
- The project is commercial, multifamily or agricultural and falls under the IBC, where truss submittals are routinely reviewed.
- The truss layout changed after the architectural plans were approved, moving bearings or girders.
- Trusses were cut, notched, drilled or damaged and need an engineered repair.
- You want to add load the trusses were not designed for, such as attic storage, mechanical units, solar panels or a heavier roof covering.
The ANSI/TPI 1 standard and the building codes split responsibility for trusses between the truss designer, who designs each individual truss, and the building designer, who makes sure the trusses fit the building, receive the right loads and are properly supported and braced. On many residential projects nobody has formally taken the building designer’s role. That gap is often exactly what the plan reviewer is asking someone to fill, and we can fill it.
What our truss review checks
A truss package can be internally correct and still be wrong for the building. Our review focuses on the places where trusses and the rest of the structure meet.
- Design loads. We confirm the roof dead load matches the actual roofing, that ground snow, unbalanced snow and drift against taller roofs are included where they apply, and that wind exposure and speed match your site. Collateral loads for ceilings, sprinklers or equipment are checked on commercial projects.
- Geometry. Spans, pitches, heel heights and overhangs are compared to the architectural plans, along with attic rooms, vaulted areas and mechanical spaces.
- Bearings. Every reaction is traced to a wall, beam or header. Girder trusses often deliver large point loads, so we check the post or stud pack below and the footing at the bottom of that path.
- Uplift. Uplift reactions are matched with connectors at each bearing, and the load is followed down the wall to the foundation.
- Girders and hangers. Multi-ply girder fastening and truss-to-girder hangers are confirmed for the reactions shown.
- Bracing. Permanent lateral restraint and diagonal bracing for truss webs and chords are shown, along with references to the BCSI guide for installation bracing.
Anything that does not match goes back to the truss supplier as a clear, numbered comment list. Once the revised drawings come back, we verify the changes before sealing.

Truss stamp for out-of-state and third-party truss packages
Truss manufacturers often supply projects across several states, and their in-house engineer may not hold a license everywhere they deliver. When a project lands in a state where the truss drawings need a seal from a locally licensed engineer, the supplier or the contractor can send the package to us.
Our process is straightforward:
- You send the truss design drawings, the truss placement plan, the architectural plans and the site address.
- We perform an independent engineering review of the design loads, the individual truss designs and their fit with the building.
- We send any questions or corrections to the supplier and review the revisions.
- The truss package is sealed by a PE licensed in the project’s state, ready to submit.
We do not apply a truss stamp to drawings we have not checked. The seal means a licensed engineer has reviewed the work and takes responsibility for it, which is why plan reviewers trust it. The same approach applies to other drawings prepared by someone else, through our third-party plan review and stamp service.
Because truss deliveries are usually tied to a framing schedule, we understand the time pressure. Rush review is available, and we communicate directly with the truss supplier’s designer to keep questions from bouncing through several people.
Truss repairs, modifications and added loads
Trusses are efficient precisely because every member is working. Cutting a single web or chord can make the whole truss unstable. Unfortunately it happens often: a web is removed to fit a furnace or attic stairs, a chord is notched for a duct, a skylight opening is cut, or a truss is cracked during delivery or installation.
A damaged or modified truss should never be left as is or patched by eye. We engineer a repair specific to the damage, typically using plywood or OSB gussets, lumber scabs, added webs or new bearing, with the fastener type, spacing and length specified. The repair detail is sealed so the framing inspector can approve it. When many trusses are affected, a structural redesign of that part of the roof can be more practical than repairing each one.
Added loads raise a similar question. Converting an attic to storage, hanging a heavy mechanical unit from the bottom chord, installing a heavier roof covering or adding rooftop equipment can all exceed the original truss design. For solar panels specifically, our solar structural letters evaluate the trusses or rafters for the added array load. For other changes, we check the existing trusses against the new loads using the original truss drawings when available, and design reinforcement where needed. If the roof needs to be reframed entirely, our framing plans service handles the redesign.

Codes and standards for truss review
Truss reviews and repairs follow the code editions your jurisdiction has adopted and the national truss standards they reference:
- International Building Code (IBC) Chapter 23 truss provisions
- International Residential Code (IRC) roof-ceiling and floor truss provisions
- ANSI/TPI 1, National Design Standard for Metal Plate Connected Wood Truss Construction
- ASCE 7 for dead, live, snow and wind loads
- AWC National Design Specification (NDS) for Wood Construction
- SBCA and TPI BCSI guide for handling, installing, restraining and bracing trusses
How licensing works. Engineering drawings must be sealed by a Professional Engineer licensed in the state where your project is located. PE Engineer works with a network of state-licensed PEs, so every set is reviewed and stamped by an engineer with an active license in the state where your project is located. Their name and license number appear on the seal, exactly as your building department requires.

Who designs the trusses, the supplier or you?
The truss supplier designs each individual truss and produces the truss design drawings. We review those drawings, check that they suit the building and the loads at your site, coordinate corrections, and provide the engineer’s seal and any connection, bearing or bracing details the building department requires.
Why won't my building department accept the supplier's truss drawings?
Common reasons are that the drawings are not sealed by an engineer licensed in your state, the design loads do not match your site’s snow or wind requirements, or the reviewer wants the engineer of record to confirm compatibility with the rest of the structure. We address each of those.
Can you stamp trusses for a garage, barn or shop?
Yes. We review and stamp truss packages for garages, shops and barns as well as houses. Long spans and heavy snow loads make these packages more demanding, and we check the posts, headers and girders that support them as well as the trusses themselves.
How do I fix a truss that was cut or damaged?
Do not load it further and do not patch it without a design. Send photos showing the damage, the truss design drawing for that truss if you have it, and its location in the roof. We engineer a sealed repair detail your framer can install and your inspector can approve.
Can I add attic storage or a furnace to my roof trusses?
Only if the trusses can carry it. Most standard trusses are designed for a light bottom chord load. We check the trusses using the original truss drawings or measurements and design reinforcement, or an independent platform, if the new load exceeds their capacity.
What do you need for a truss review and stamp?
The truss design drawings, the truss placement plan, the architectural plans and the project address. For repairs, add photos and a description of the damage. We usually quote a fixed fee the same day, and rush review is available when deliveries or inspections are scheduled.
