How Roofs Should Be Addressed in a BC Strata Depreciation Report
A roof line in a strata depreciation report should do more than attach one replacement year and one cost to the entire building.
Many strata properties have several roof areas, different installation dates, multiple roofing systems and concealed components that cannot be understood during a single visual walk. If those differences disappear into one generic entry, the council may have little basis for deciding what to maintain now, what needs further investigation and what should be included in the contingency reserve fund forecast.
This guide explains how BC strata councils and property managers can prepare better roof information for the qualified person writing the depreciation report. It is about making the roofing portion of the report more complete and usable. It is not legal advice, a project specification or a substitute for the statutory report.
What BC currently requires
Under BC's current rules, strata corporations with five or more strata lots must obtain a depreciation report on a five-year cycle. The former option to defer the report through an annual three-quarter vote is no longer available. Strata corporations in Metro Vancouver, the Fraser Valley and the Capital Regional District that did not have a report, or whose report was received before December 31, 2020, had a July 1, 2026 deadline. The corresponding deadline for other areas of BC is July 1, 2027, subject to the geographic exceptions and new-strata timelines described by the Province.
The Province's current depreciation-report requirements should be checked for the corporation's specific circumstances. Since July 1, 2025, the report provider must also belong to one of the designated professional groups and have the knowledge and expertise required by the regulation.
Section 6.2 of the Strata Property Regulation requires a physical component inventory and evaluation based on an on-site visual inspection where practicable. The inventory must address the common property and other components the strata corporation is responsible to maintain or repair. The regulation expressly includes the building exterior, including roofs, roof decks and skylights. It also requires anticipated maintenance, repair and replacement costs over 30 years and at least three cash-flow funding models.
Those are statutory requirements for the qualified depreciation-report provider to interpret and satisfy. Raven Roofing does not replace that provider or prepare the statutory depreciation report unless the person preparing it independently meets the applicable professional and regulatory qualifications. A roofing contractor's useful role is narrower: documenting roof systems and observed conditions so the qualified provider has better source information.
A depreciation report and a roof condition review are different documents
The two documents can support each other, but they answer different questions.
| Document | Main purpose | Typical roof output | Important limit |
|---|---|---|---|
| Statutory depreciation report | Inventory common assets and forecast major maintenance, repair and replacement costs and funding over 30 years | Component descriptions, estimated service-life timing, planning costs and funding models | Usually based on visual review; it is not automatically a technical audit or construction specification |
| Roof condition review | Document the observed condition of identified roof areas and components | Roof plan, system information, photographs, deficiencies, priorities, limitations and possible next investigations | Visual findings do not reveal every concealed condition or provide certainty about remaining service life |
The Province's practical tips for depreciation reports make a similar distinction: the physical component inventory is not the same as a technical audit, and problem areas may require additional testing. A council should therefore avoid assuming that a depreciation-report site visit is a detailed roof investigation unless the agreed scope says so.
If the roof history is incomplete, leaks recur, several roof sections have been installed at different times or concealed moisture could change the capital decision, a separate commercial roof inspection or condition assessment may provide the report author with a stronger evidence base.
Build the roof inventory by area, not just by building
A useful inventory begins with a roof plan and consistent identifiers such as Roof A, Roof B and Podium 1. Each area should be described separately when its age, system, elevation, drainage or exposure differs.
For each applicable area, record:
- membrane or roof-covering type, including whether the section is low-slope or steep-slope;
- approximate installation date and the source of that date;
- known recover, replacement, alteration and repair history;
- deck type where records or prior openings establish it;
- insulation, cover board, vapour-control and air-control information where known;
- perimeter edges, parapets, copings and roof-to-wall transitions;
- drains, scuppers, overflows, gutters and leaders associated with the area;
- curbs, vents, pipes, roof hatches, skylights and other penetrations;
- rooftop equipment, walkways, amenity overburden or solar equipment that affects access and maintenance; and
- warranties, maintenance obligations and known exclusions.
Do not fill information gaps with assumptions. Mark an assembly layer, installation date or responsibility boundary as unknown when the available documents do not establish it. An explicit unknown can be investigated or carried as planning uncertainty; an undocumented guess may create false precision.
Assemble a roof-information package before the site visit
The quality of a depreciation report depends partly on the information supplied by the strata corporation. The Province recommends gathering maintenance and repair documentation and speaking with people familiar with the property because a visual visit may not reveal seasonal or historical problems.
Provide the qualified report author with the most relevant available records:
- roof plans, architectural details and original specifications;
- prior depreciation reports and building-envelope reports;
- roof replacement, recover and major-repair contracts;
- closeout documents, product information and as-built records;
- manufacturer, contractor or association warranty documents;
- inspection reports;
- maintenance logs, invoices and dated repair photographs;
- leak incident records showing dates, weather and interior locations;
- records of new HVAC units, solar work, penetrations and tenant alterations;
- council-approved projects that have not yet been completed; and
- relevant bylaws or agreements affecting maintenance responsibility.
Organize records by roof-area identifier and date. If a 2019 invoice says only "roof repair," it may not help a future reader understand which membrane or detail was repaired. A short index that maps each record to Roof A, Roof B or another plan reference can make the package much easier to use.
Describe condition, uncertainty and evidence separately
An installation date is not a condition assessment. Two roof areas of the same age may perform differently because of design, materials, exposure, drainage, workmanship, alterations, traffic and maintenance history.
For each roof area, the planning record should distinguish:
- Known facts: system type, documented installation date, warranty term or completed repair.
- Observed conditions: open seams, damaged flashings, blocked drainage, membrane wear, corrosion or past interior staining observed during the stated review.
- Professional opinions: a condition rating, planning horizon or recommended action, with the basis and assumptions stated.
- Unknowns: concealed moisture, undocumented layers, inaccessible sections, deck condition or uncertain responsibility boundaries.
Remaining-life estimates are planning ranges, not promises. They should be revisited when new evidence appears or conditions change. A roof that has reached a generic age benchmark is not automatically failed, and a younger roof is not automatically free of material defects.
Where a decision depends on concealed conditions, the report may recommend additional work such as records research, selective openings or an appropriately designed moisture investigation. These methods have different limitations. Raven's guide to roof moisture investigation methods explains why anomalies generally need context and confirmation before they are used to define a repair or reroofing scope.
Separate recurring maintenance from capital events
The depreciation report's financial forecast focuses on common expenses that occur less often than once a year or do not usually occur. The Province notes that everyday routine repairs and maintenance are generally handled through the annual operating budget instead.
For roofs, it is useful to maintain separate planning lines for:
- recurring inspection, drainage cleaning and preventive maintenance;
- near-term investigation needed to reduce an important uncertainty;
- targeted repairs to identified details or areas;
- less-frequent major maintenance or restoration, where technically appropriate; and
- eventual replacement of each distinct roof area, including related access and interface allowances identified by the report provider.
Combining those categories into one distant "roof replacement" number can hide work needed before the forecast replacement year. Conversely, moving every small annual task into the depreciation report can make the capital plan harder to read. The qualified provider and strata's financial or legal advisers should determine the correct treatment for the corporation.
Planning costs should also state what they include. Roof work may affect removal, temporary protection, drainage, sheet metal, curbs, deck repairs, insulation, permits, design or consulting, testing, access, overburden and taxes. Not every item applies to every property, and concealed conditions may require an allowance rather than a fixed prediction. Figures in a depreciation report are planning inputs, not contractor quotations or guaranteed future prices.
Check decks, skylights, equipment and responsibility boundaries
The word "roof" can conceal several separate assets and scopes. The regulation specifically identifies roofs, roof decks and skylights, but the correct inventory depends on what the strata corporation is responsible to maintain under the Act, bylaws and any agreements.
Ask the report provider how the inventory treats:
- the roof covering versus structural or non-structural deck components;
- skylight units, curbs and surrounding flashings;
- podium or amenity membranes concealed below pavers, landscaping or other overburden;
- roof drainage components and their connections to plumbing systems;
- rooftop mechanical equipment versus its curbs, supports and waterproofing interfaces;
- owner-installed equipment or alterations; and
- limited common property or strata-lot components with different repair obligations.
These are coordination questions, not an invitation for a roofing contractor to assign legal responsibility. If the bylaws, strata plan or agreement is unclear, the council should obtain advice from the appropriate qualified professional or lawyer.
Review the draft roof section before the report is finalized
When the qualified provider issues a draft, compare the roof section against the records and roof plan. The Province specifically advises councils to check the component list, assumptions, figures and whether template information from another property has appeared by mistake.
Questions to ask include:
- Are all materially different roof areas identified?
- Are installation dates labelled as documented, estimated or unknown?
- Does the condition description match the latest roof report and repair records?
- Are active deficiencies separated from longer-term lifecycle planning?
- Are concealed or inaccessible conditions clearly limited rather than assumed?
- Do cost allowances identify major inclusions, exclusions and assumptions?
- Does the forecast avoid counting the same component in two different asset lines?
- Is further investigation tied to a decision and a realistic planning date?
- Are routine operating-budget tasks kept visible somewhere in the strata's annual plan?
The aim is not to force a false level of detail into the depreciation report. It is to make sure the report's planning assumptions can be traced to the best information currently available.
Turn the report into an annual roof-planning cycle
A five-year reporting cycle does not mean the roof information should sit untouched for five years. The Province explains that updated reports need to reflect assets that last longer or shorter than predicted, changes in costs and materials, completed work and new site information.
Between statutory reports, a strata council can keep the roof record useful by completing a simple annual cycle:
- Update the roof plan and document index after repairs, replacement or alterations.
- Review current inspection and maintenance findings by roof area.
- Record which recommended work was completed, deferred or changed.
- Compare new evidence with the depreciation report's timing and assumptions.
- Ask the qualified report provider or other appropriate adviser whether a material change should affect capital planning before the next scheduled update.
Regular roof maintenance can help a strata track changing conditions and preserve a clearer history, but it cannot guarantee a particular service life or eliminate the need for future capital work.
Prepare evidence before assigning a replacement year
The most useful roof entry in a BC strata depreciation report connects four things: a clearly identified asset, current condition evidence, stated uncertainty and a planning response. That may mean maintenance now, further investigation, a targeted repair allowance, a replacement scenario or continued monitoring with defined review points.
Raven Roofing can help strata councils and property managers document existing roof areas and observed conditions before the qualified depreciation-report provider completes the statutory report. A roof condition assessment should be scoped around the building, the available records and the decision the council needs to support.
Frequently asked questions
Does every BC strata corporation need a depreciation report?
The Province says strata corporations with five or more strata lots must obtain reports on a five-year cycle. Strata corporations with four or fewer lots are exempt from this requirement. New strata corporations and corporations in different regions may have different first-report deadlines, so confirm the current rule for the specific corporation.
Can a roofer prepare the depreciation report?
Only if the person preparing the statutory report independently satisfies the current professional designation, knowledge and expertise requirements. A roofing contractor can provide roof-specific condition information, but that supporting review does not itself become the statutory depreciation report.
Should one replacement year be used for the whole roof?
Not automatically. Separate dates or planning scenarios may be more useful where roof areas differ in system, age, condition or risk. The report provider should explain how areas were grouped and what evidence supports the selected timing.
Does a visual review establish the roof deck's condition?
Only to the extent that the deck is visible or reliable records and prior openings establish relevant information. A visual roof-surface review generally cannot confirm every concealed layer or deck condition. If that uncertainty could change a major decision, the appropriate next investigation should be discussed.
Is the replacement cost in a depreciation report a quotation?
No. It is a planning estimate built on stated assumptions and projected over time. Actual project pricing depends on the eventual scope, design, site access, concealed conditions and market conditions when the work is procured.
