Our FAQ

An inspection evaluates the general condition of the roof and produces a deficiency report. An assessment goes further: it identifies the causes of a specific problem — persistent infiltration, construction deficiency, hidden defect — and produces a document usable for a legal or financial decision.

An inspection twice a year — spring and fall — is generally recommended for commercial roofs. This frequency allows for the detection of winter damage and prepares the roof before the cold season. Bill 16 also reinforces this obligation for condominium associations.

Asset management involves tracking the condition of multiple roofs over a multi-year horizon — evaluating remaining service life, planning interventions, and optimizing budgets. It is a particularly useful service for property portfolio managers, school boards, and healthcare networks.

A roofer evaluates a roof with the potential to sell work afterwards. Gestion Defcor does not carry out full re-roofing projects — our opinion is structurally neutral. This model produces a diagnosis you can use to decide, negotiate, or contest without any conflict of interest.

Yes. The technical consultation includes a comparative analysis of quotes — identifying what is justified, what is missing, and what is superfluous. It is one of the most frequent mandates, particularly for condominium associations that need to approve major work.

Our primary mandate is independent consulting and expertise. For certain minor corrective work identified during a mandate, we have an internal technical team. Contact us to discuss your specific situation.

Thermography detects temperature differences — a method sensitive to weather conditions and stray heat sources such as debris. The Tramex Dec Scanner measures electrical impedance to confirm the actual presence of water beneath the membrane, with a lower risk of false positives.

It is particularly useful before a resurfacing project to target the zones to remove, after a repaired infiltration to confirm that the moisture has not spread, or during a real estate transaction to validate the true condition of the system in place.

Bill 16 requires condominium associations to maintain an up-to-date maintenance logbook and an adequate contingency fund. An independent roof inspection or expertise constitutes a solid reference document for meeting these obligations and protecting the association in the event of a dispute.

Yes. Gestion Defcor holds RBQ licence 5772-1268-01, issued by the Régie du bâtiment du Québec. This licence confirms that the company meets the legal requirements to carry out construction and inspection activities in Quebec.
