Roof Condition Assessments

In order to give good advice, one needs to know the available specifics of your existing roof assemblies (structure, deck, vapor retarders, insulation, slope, membrane type and date of installation, number of roof membrane layers, penetration locations and flashings).  Facility managers that have existing records can shorten the time needed to gather this data.

Depending on the degree of detail requested by the owner, Roof Assessment Surveys can be as simple as a visual inspection with the owner to provide onsite verbal comments and recommendations; a comprehensive survey in the beginning of a roof asset management program may include such things as:

  • An overall roof plan (when the building complex is too large to show roof detail of each sector).
     
  • A scaled roof plan of every sector with notations and/or photos of special features or typical deficiencies.
     
  • All previously known existing data for each roof and each sector such as roof assembly components, product manufacturer, installing contractor, leak history (if any), and repairs.
     
  • Documentation of all newly gathered roof assembly data regarding structure, deck, vapor retarders, insulation, slope, membrane type and date of installation, number of roof membrane layers, penetration locations, flashings, and asbestos test results.
     
  • Results from the detailed visual inspection and sometimes nondestructive testing such as:

    - Infrared Thermography

    - Electro-capacitance surveys

    - Nuclear grid sample surveys

    - Electro-vector mapping

    - Fastener pullout test →
  • Detail perimeter edge and adjacent wall or curb flashing.
  • Preliminary repair alternative options (spot repair, coating applications, recover overlays, reroof replacement) and recommendations.
     
  • Preliminary budget estimates, energy saving potential, life-cycle cost estimates.

To gather data needed for a comprehensive condition survey the work may sometimes require, site measurements, GPS surveys, transit elevation measurements, core cut analysis, electronic probes, deficiency counts, location maps, photo location maps, larger scale drawings of complicated areas with numerous penetrations & rooftop equipment, section detail drawings, and overall roof evaluations.

   

Roof Assessment Reports are a valuable tool for building owners to manage their existing roofs, prioritize spending, and make informed decisions regarding their future roof asset budget needs.   Every building owner’s need for this service varies according to number of buildings, number of roofs, type of roofs, and the extent that they need professional assistance.  Therefore, ConSpecT will review your needs and expectations, then prepare a proposal to provide a customized roof assessment tailored to your unique needs.
