Commercial Roof Repair and Protection

Retrofit Design

Our design team provides a wide range of retrofit design services that carefully match the challenges of each unique project. These services range from simple repair recommendations to complete retrofit bid documents, which will include detailed drawings and technical specifications so that you can visualize the outcome of your project. Our retrofit design projects carry the same detail-oriented approach and thoroughness we commit to new construction projects.


Our retrofit design services are available for every commercial roof or building envelope project, and include:


  • Preparation of the project’s design documents (instructions to bidders, technical specifications, and detail drawings)
  • RCW 64.55 compliance services (Washington State’s “Condo Act” Law)
  • Preparation of all maintenance manuals
  • Assistance in helping you to prioritize your individual project’s unique aspects of work
  • Facilitation of pre-bid job-site meetings with contractors
  • Taking the project out for bid
  • Helping you select the winning bid
  • Quality Assurance Monitoring
  • Project Management


No matter the scope of your project, our design team will prepare the documents, take the project out for bid, and help you select the winning contractor to ensure your project is completed properly and that it meets or exceeds your requirements.
