Roofing Assessment
Do You Have a Roofing Problem Nobody Can Explain?
Some roofing problems go beyond the scope of an ordinary visual inspection — hidden defect, construction deficiency, dispute between parties, insurance claim. Gestion Defcor performs independent roofing assessments for condominiums, institutions, and property managers in Montreal, on the South Shore, and across Quebec.
Finally get an independent technical opinion.
Independence as the Foundation of the Diagnosis
A contractor assesses a roof with their own interests in mind. Gestion Defcor acts with nothing to sell — our diagnosis aims for technical truth, not a conclusion favourable to one party or the other.
This positioning makes our report a document that all parties — the condominium association, the insurer, the lawyer, the manager — can consider neutral and actionable.
What a Roofing
Assessment Includes
Complete Technical Analysis
We examine all components of the roofing system:
- Membrane: General condition, cracks, delamination, abnormal wear
- Joints, Terminations, and Flashings: Sealing at critical junctions
- Drains and Slopes: Water pooling, obstruction, design
- Mechanical Penetrations: Quality of sealing around units
- General Conditions: Aging, visible history, prior repairs
Root Cause Analysis
The assessment does not stop at observation — it explains. We identify the probable origin of each observed deficiency:
- Inadequate installation or non-compliant with industry standards
- Design defect affecting the durability of the system
- Premature aging linked to lack of maintenance
- Execution error during prior work
- Localized infiltration that was misdiagnosed and poorly repaired
Professional Report
The report produced by Gestion Defcor is designed to be used, not filed away in a drawer. It includes:
- Captioned technical photos for each documented deficiency
- Objective findings stated without ambiguity
- Structured conclusions with identification of causes
- Actionable recommendations tailored to the mandate's objectives
When To Get an Assessment
A Montreal roofing assessment applies to very different contexts. Here are the most common scenarios in which Gestion Defcor is mandated.
Litigation or Insurance Claim
Your insurer is contesting the cause of the damages, or a dispute has arisen between the condominium association and the contractor. An independent assessment report establishes the technical facts without bias — a document both parties can submit in the context of proceedings.
Recently Completed Work Already Showing Problems
A roof re-done less than two years ago is already showing infiltrations or visible deficiencies. The assessment determines whether the problem stems from a construction deficiency, a material defect, or an external cause — and supports a claim if necessary.
Building Purchase or Sale
Before signing a promise to purchase on a commercial building or condominium, an independent roofing assessment validates the true condition of the system. It can influence the sale price, the conditions of the transaction, or the final decision.
Condominiums and Bill 16
Bill 16 requires condominium associations to document the condition of their assets and maintain an adequate contingency fund. An independent roofing assessment constitutes a solid reference document for meeting these obligations — and for protecting the association in the event of a dispute.
From Montreal to Gaspésie, we operate across Quebec.
