To Submit for a WTW:

  • Completely fill out the entire WTW Submittal Package.
  • Provide all documents outlined in the WTW Submittal Package including details.
  • Send information to Sheffield Metals Technical Department. Email is preferred.
  • All products used in a WTW are required to be purchased from SMI. The only exception to this is if the product is not offered by SMI. (i.e. curbs, rigid insulation etc.) All items not supplied by SMI must be approved by the SMI Technical Department.
  • Non Engineered profiles are not approved for WTW applications. The SMI 1.0 FF will not be approved for a WTW in any situation.
  • WTW’s require the minimum use of a synthetic and peel and stick UDL combo installation (Sharkskin Ultra and Ultra SA) but most WTW’s will require a full peel and stick UDL installation (Sharkskin Ultra SA) for WTW approval.
  • WTW’s will require that either Novaflex Metal Roof Sealant, TFC 1000 or APS 500 sealant be used. Novaflex Metal roof Sealant is preferred.
  • All WTW installations are required to be installed per the project engineering requirements. If there are no requirements set the roof will be installed per UL 90.
  • If a penetration is too large to use a pipe boot on, a pre-manufactured curb approved by the SMI Technical Department will be required.
  • Any square penetration will require a pre-manufactured curb approved by the SMI Technical Department.

After Sheffield’s Technical Department receives the submittal package:

    • Invoice for required inspections, if required. (All inspections fees must be paid prior to the inspection taking place.)

During the project installation:

  • Inspections are required based on the length and type of WTW; inspections are as follows:
    • A ZOOM will be scheduled with a supervisor of the installation contractor who will be on site for the duration of the project. During the Zoom the approved details will be discussed and any questions answered. This is mandatory and will be required to take place before the project starts.
    • In-Progress – To be conducted while the roof install is in progress, as necessary.
    • Final – To be conducted after the roof is 100% installed.
  • Inspections are to be scheduled at least 3 weeks in advance.
