A thorough review, testing, and modeling provided essential insights for the client, ensuring alignment with IO Sustainability Guidelines and offering cost-effective repair options for low-slope roofing systems.  

The facility is one storey, has a footprint of approximately 1190m2 (12,800ft2), and houses a public health lab requiring OPS security clearance. The purpose of the roof study was to provide a detailed condition assessment of the existing roof assembly including drains, flashings, etc. Physical review, thermography, destructive testing, and preliminary energy modeling using RETScreen were performed by Pretium.

The report included findings of the physical review, thermographic scan, and destructive testing, as well as multiple repair/replacement options considering IO Sustainability Best Practice Guidelines, and opinions of probable cost. The report also included annual maintenance recommendations, an analysis and comparison of several low slope roofing systems, as well as preliminary energy modeling and considerations. 

Client Benefits 

Pretium determined the overall condition and estimated the remaining service life of the existing roof, made recommendations regarding repair vs. replacement, and provided opinions of probable cost. Pretium developed a roof maintenance manual for the owner.

To deliver this project, Pretium completed the following measures:

Condition Assessment / Feasibility Study 

Condition Assessment / Feasibility Study 

A detailed assessment of existing conditions, including drawings, permitted use, failure mechanisms, rnand remedial options, allows for our clients to choose the building restoration and renewal program that best suits their objectives.
Infrared Thermography

Infrared Thermography

Infrared thermography is used in building science to detect thermal variations in building envelope assemblies using non-destructive infrared (IR) radiation detector sensing equipment. Detection of these thermal variations can be used to identify a variety of potential deficiencies.
Roof Openings / Test Cuts

Roof Openings / Test Cuts

Our team creates small openings to determine roof compositions including the type of membrane, type and thickness of thermal and tapered insulation and overall roof assembly height, type of vapour barrier, and the condition of the roof deck. Openings also allow for checking suspect areas that may be actively leaking and testing using a Delmhorst Moisture Meter.
Energy Modeling

Energy Modeling

A quantitative tool that assists designers in evaluating the environmental, technical, and financial viability of a proposed building retrofit or design for a new building. The data obtained from the analysis allows designers to communicate recommendations to building owners and managers more effectively. The information is used to identify optimal solutions.
