CLIENT OF 40+ Years
I have known Dan Winarski professionally for approximately 40 years. Mr. Winarski has provided goods and services when he was a Tremco representative, and after when he started his own firm. Services provided include roofing and building envelope design, specification and inspection services. As an added service, he has also assisted with pre-qualification documents for roofing contractors.
Over the years, I have found Dan to be the consummate professional. He has assisted and provided me with;
- Roofing review and analysis resulting in a 5-year capital plan for roofing replacement for a four hospital alliance,
- Collaboration on a roofing design to best suit hospital conditions,
- Roofing specifications and tender packages, including tender submission review,
- Project management and project review / reporting,
- Warranty reviews / repairs
- EIFS projects review / reporting
- Building envelope consultation / recommendations
- Capital budget planning
In my former role as Director, Facilities Management Department, for 6 hospitals in South Western Ontario, I have found Dan’s contributions to be invaluable from concept through to completion. Probably the best testament I can offer is that in any project that Dan and I have collaborated on, I have never experienced one single failure.

Project Manager (Capital Projects) Facilities & Asset Management Wilfrid Laurier University
Building Exterior Consultants (BEC) Inc. have been involved in many roofing projects for Wilfrid Laurier University over the past few years. Projects have included small roof renovations and full roof replacement projects.
Currently, BEC Inc. is providing roofing consulting services for the replacement of the roof at our Northdale Campus Building and have previously provided consulting services for the roof replacement at the Arts A Building.
The firm maintains a reputation of providing excellent consulting expertise and service through a combination of effective problem solving, detailed and accurate documentation, excellent coordination with the project team and trades, and a commitment to meeting project deadlines. BEC Inc. has proven themselves by continually demonstrating their ability to work with the project team, contractors, and in support of the University’s best interests.
I have found the firm to be extremely client oriented and highly professional in dealing with design, construction documents, and construction administration to ensure the University receives full dollar value in its investment for each project.
I would not hesitate to recommend BEC Inc. for any roof consulting projects.
