Ontario condo board roofing quote review under the Condominium Act
Written by Marc D., GCT Expert Analyst · Updated April 2026 · 2 min read
Ontario condo directors face personal exposure on roofing decisions. Here is the Condominium-Act-aligned method to review a roofing quote without errors.

Direct answer
Under Ontario's Condominium Act, 1998 (s. 37), condo directors owe a fiduciary standard of care to the corporation. A defensible roofing-quote review requires three things: a comparable tender on identical scope, an independent technical review by a qualified third party (engineer, technologist or specialized review service), and a documented decision trail in the board minutes showing why the chosen bid was selected.

Why rigour is non-negotiable
An Ontario condo roof typically represents $120,000 to $850,000. A poorly documented decision can:
- Personally expose directors (s. 37 due-diligence standard)
- Trigger an owners' action
- Void D&O (directors & officers) insurance coverage
- Compromise reserve-fund-study compliance under s. 94
- Conflict with the management agreement's procurement clauses
Step 1 — Comparable tender
Issue an identical specification to every bidder:
- Measured roof area (engineer-stamped or independent survey)
- Membrane / shingle type, brand, model, thickness, warranty
- Insulation R-value (Ontario Building Code SB-12 alignment)
- Parapet, drain, scupper, curb details
- Access plan, parking impact, owner-notice timing
- Working hours (noise impact on residents)
- Warranty terms required (manufacturer + installation)
- Acceptance, holdback (Construction Act 10% statutory holdback) and substantial-performance protocol
Different scopes = unusable comparison = unprotected directors.
Step 2 — Independent technical review
Mandate a qualified third party (P.Eng., C.E.T., or specialized review service like GCT Expert) to:
- Confirm quantity coherence
- Surface hidden exclusions
- Compare membrane brands and CSA certifications
- Weight lifespan against price
- Confirm WSIB clearance, $5M+ liability, completed-operations coverage
- Review the contract for Ontario Construction Act compliance (holdback, notice of non-payment, adjudication rights)
Step 3 — Documented decision trail
Board minutes must record:
- All bids received (count, amounts, dates)
- Weighted evaluation criteria
- The independent reviewer's report (attached as schedule)
- Justification for the chosen bid (even if not the lowest)
- Project oversight assignment (board sub-committee or property manager)
- Notice-to-owners plan under s. 97 if substantial change
This trail is the directors' primary defence in any subsequent dispute.
Weighted evaluation grid
| Criterion | Weight |
|---|---|
| Technical conformity to tender | 30% |
| Total price + exclusions clarity | 25% |
| Condo experience + verifiable references | 20% |
| Installation warranty + financial strength | 15% |
| Project-management plan (noise, access, owner notice) | 10% |
Common Ontario condo-board mistakes
- Picking the lowest bidder "to preserve reserve fund"
- Accepting bids on different scopes
- Skipping the independent technical review (false economy on a $300k project)
- Approving without a written report on file
- Omitting the statutory 10% holdback clause
- Releasing the holdback before publication of substantial performance per Construction Act s. 32
- Paying deposits from the reserve fund without legal review
