Roof Repairs to the 2014 Lexus IS 250 and 350

LEXUS USES THE LATEST in high-tech manufacturing processes when assembling the 2014 IS 250 and 350 in the factory. Each vehicle’s roof is laser brazed to its body, resulting in a cleaner, more sophisticated appearance. The task is carried out by robots and takes about a minute to complete. While this makes for an excellent assembly process in the factory, laser brazing cannot be duplicated in the collision repair shop. As a result, replacing the roof on these vehicles must follow an alternative method. Shops working on the IS 250 and 350 should follow Lexus-recommended repair instructions in order to properly carry out this work.

“As with any repair to a Toyota, Lexus or Scion vehicle, start by consulting the instructions in TIS,” says Joe DiDonato, Collision Training Administrator, Technical & Body Training Department, Toyota Motor Sales, U.S.A., Inc. “TIS will explain what is involved in the repair and give you detailed instructions about how to perform each portion of the project. Following the OEM instructions is the best way to ensure your repair is safe and meets the Lexus standard for fit, quality and finish.”



Replacing the roof on the IS 250 and 350 does not follow the procedures of a typical roof replacement job. Toyota’s Technical Information System (TIS) recommends affixing a replacement roof to the vehicle with a series of brackets that are used to secure the roof to the frame. This process involves using a new roof panel, roof panel reinforcement brackets, roof panel reinforcement plates and adhesive. The basic steps are:

  • Bond the roof panel reinforcement brackets to the new roof.
  • Weld roof panel reinforcement plates to the vehicle’s roof frame.
  • Apply bonding materials to the adjoining parts.
  • Bolt the roof panel to the vehicle through the reinforcement plates.

This repair requires more time and detail than a standard roof replacement repair job. Technicians must make precise measurements to ensure that all tabs are affixed in the correct location. The tabs come in different sizes for different locations, and precise placement of each tab is crucial. At each stage of the process, the bonding agent must be given enough time to dry sufficiently. Proper planning, scheduling and closely following the repair procedures are necessary to execute this job correctly. Before undertaking this repair, ensure that you have read the relevant repair instructions in TIS and understand the scope of the project.

“Replacing the roof of the IS 250 and 350 is a unique repair job that requires patience, diligence and precision,” explains DiDonato. “This repair will be an involved, time-consuming project for any shop that undertakes it. Taking the required time and making sure it’s done right are crucial to delivering a repair that works as intended and looks great.”



Another element to accomplishing this repair properly is making sure that the lines of communication between your client and all parties involved are open. This means informing all parties about the nature of the repair and the labor, time and cost required. This will ensure that all parties have reasonable expectations about the repair and can help head off questions about the repair’s lengthiness or cost.
