A depreciation report is a forecast, and a forecast is only as good as the data feeding it. For the exterior of a building — roofing, gutters, cladding, hardscape — most of that data comes from routine maintenance visits, which means what gets documented during those visits matters well beyond the day the work is done.
An invoice line isn’t evidence
“Gutter cleaning — completed” tells a depreciation report nothing about condition. What actually helps the next assessment is a record that shows what the component looked like at the time: photographs of the roofline, the gutters, the hardscape, taken during routine work rather than commissioned separately for the report.
Deficiencies belong in the file the moment they’re found
If a contractor notices a lifted shingle, a separated gutter seam, a hairline crack in sealed concrete or early efflorescence while doing routine work, that observation is worth more written down immediately than recalled months later from memory. We report anything we find with photos as a matter of course — not as an upsell, as part of the job — specifically so it lands in the property’s file at the point it was actually noticed, not reconstructed later.
Dates matter more than descriptions
A depreciation report models when a component will need replacing, which depends on knowing when it was last serviced or treated — not just that it was. A roof moss treatment with a moss-free guarantee term attached, for instance, gives a concrete date range the next report can work from, rather than a vague “treated at some point.”
Consistency across buildings
For a multi-building complex, the report needs comparable records across every block, not detailed notes on one building and nothing on the others. Scoping exterior maintenance as one coordinated program across the whole property — see scheduling roof moss treatment across a strata complex — is partly why: the documentation comes back in the same format for every building, which is what lets the next report actually compare them.
What a council can ask for directly
If your current contractor doesn’t provide photographed, dated records as standard, it’s reasonable to ask for them specifically — a depreciation report prepared without that input is working from less information than it should have. Confirm it’s part of the scope in writing before the work is approved, not requested afterward as an afterthought.
How we document every visit
Every job — gutters, roof treatment, pressure washing, sealing — comes back with completion photographs and a written note of anything found along the way, delivered to the property manager or council contact on file. The strata services overview covers how that documentation fits into the rest of how we scope and schedule recurring work, and what to ask for in a strata exterior maintenance quote covers what should be agreed to before the work even starts.
Send us the property details and we’ll confirm how documentation works for your specific scope before anything is booked.
