Roof Specifications, System Design and Bid Review

When it's time to replace a roof, a clear specification lets you get comparable bids and hold the contractor to a defined system. We write roof specs based on the building, its current roof, how it's used and what the owner needs it to do.

What goes into a specification

  • System choice and the reasons for it: TPO, PVC, EPDM, modified bitumen, metal or a coating
  • Tear-off vs. recover, deck repairs and insulation
  • Attachment method, edge metal, flashing and drainage details
  • Manufacturer warranty requirements to put in the bid documents
  • Code and wind-uplift requirements that apply to the building, as confirmed by the design professional where one is required
  • Submittals, inspections during the job, and closeout documents

Bid review and oversight

We can review bids against the spec, answer contractor questions, and inspect the work during installation so what gets built matches what was specified.

Where a project requires a licensed engineer or architect, our specification work supports theirs; it doesn't replace it.

Who we work for: Blake consults for insurance carriers and for building owners, and takes appraisal and umpire assignments for carriers and policyholders on large commercial, institutional and multi-building losses, available nationwide. In Texas and Oklahoma, Blake takes consulting projects of any size, including residential appraisal and umpire work. See Texas and Oklahoma.

Frequently asked questions

Will you bid on a roof you specify?

Tell us up front how you want to handle it. Many owners want the consultant independent of the bidders, and we respect that.

Which roof systems do you specify?

Single-ply (TPO, PVC, EPDM), modified bitumen, built-up, metal, coatings, and steep-slope systems.
