A property condition report is the written deliverable of a property condition assessment: a building walked, its records reviewed, its systems described, and two tables produced. The first lists immediate repairs. The second is a replacement reserve schedule placing major items in future years. For most commercial buildings the roof is the largest single line in the second table.
That gives the roof line in this one document more influence over a purchase price than any other sentence written during diligence. It is also, on a surprising number of reports, the line produced with the least evidence behind it.
What is inside the report
| Part | What it holds | Who reads it closely |
|---|---|---|
| Executive summary | The headline findings and the big numbers | The investment committee |
| System narratives | Description and condition, division by division | The asset manager |
| Immediate repairs | Work needed now, with costs | The buyer, during negotiation |
| Replacement reserves | Major items placed in future years | The lender and the model |
| Photographs | Evidence for the narrative | Whoever disputes a finding |
| Limitations | What was not examined, and why | Almost nobody, and it should be first |
The limitations section is the one worth reading before the summary. It tells you how much of the rest was observed and how much was inferred, and on the roof that distinction is usually the whole question. A report that says roof access was not available is not a bad report; it is a report whose roof conclusions are an estimate, and it should be read as one.
Why the roof line goes wrong
Four things combine. Roof access is often not arranged before the visit, so the roof is viewed from a hatch or a parapet rather than walked. No testing is included, so wet insulation stays invisible. Remaining life is then taken from the roof’s age against a published service life. And the replacement cost comes from an area measurement multiplied by a unit rate.
Each of those is reasonable on its own and defensible in a general assessment. Together they produce a number with no building specific evidence in it at all. Roof life expectancy explains why age alone is the weakest predictor available, and the roof section of a property condition assessment sets out what a properly scoped section contains instead.
Reading the three roof entries against each other
Take the narrative, the immediate repairs entry and the reserve year together. Agreement between them is a good sign. Disagreement is information.
A serviceable narrative with replacement in the first year or two usually means the assessor saw a roof near the end of its life. A worrying narrative with a distant replacement year usually means the year was calculated from age rather than observed. And an immediate repairs entry with no narrative explanation behind it is a finding somebody did not want to expand on.
What the report cannot tell you
A property condition report is a survey of a whole building by a generalist, and that is what it is for. It is not a roof consultant’s report and does not pretend to be. Three questions sit outside it unless they were specifically scoped in: how many layers are already on the deck, whether the insulation is wet, and what the deck is made of.
Those three decide whether the building faces a recover or a full tear off, and the difference between them is substantial. Roof due diligence at each deal stage covers where in a transaction each question is still cheap to answer.
Turning the report into a number you can use
- Read the limitations first and note whether the roof was walked.
- Check whether the roof is treated as one area or divided by age and system.
- Find the basis for remaining life and ask for it if it is not stated.
- Test the replacement cost against the layers, the deck and the code work actually triggered.
- Move anything urgent out of the reserve schedule and into the repairs table.
The roof due diligence checklist runs the same sequence as a list you can work through with the report open, and roof capital planning covers what happens to the reserve line once the building is yours.
Common questions
What is the difference between a property condition report and a property condition assessment?
The assessment is the work and the report is the document it produces. One firm walks the building, reviews records and interviews staff; the report then sets out the findings, the immediate repairs and the reserve schedule. People use the two words interchangeably, and the distinction matters when you are agreeing scope.
- The assessment is a site visit, a records review and interviews
- The report is the written deliverable with its tables and photographs
- Scope is agreed for the assessment and inherited by the report
- A thin report usually reflects a thin scope, not poor writing
- Ask what the assessor will actually do, not what the report will say
This is why arguing with a report rarely improves it. If roof access was not arranged, no amount of revision adds a walk. Settle three things when you commission the work: who gets on the roof, whether any testing is included, and whether a roofing specialist contributes the roof section. All three are scope questions, and all three are cheaper to answer before the visit than after the document is issued.
Where does the roof appear in a property condition report?
In three places, and they are read by different people. A narrative section describes the system and its condition, the immediate repairs table lists work needed now, and the replacement reserves schedule carries the reroof in a future year. The reserve line is the one that moves the price.
- A narrative section describing system, age and observed condition
- An immediate repairs entry for anything needed at once
- A replacement reserves line placing the reroof in a future year
- Photographs, ideally located on a roof plan
- A limitations statement covering what was not examined
Read the three together rather than separately. A narrative that calls the roof serviceable while the reserve schedule places replacement in the first year or two is telling you the assessor saw a roof near the end of its life and did not want to say so plainly. The reverse happens as well: a worrying narrative paired with a distant replacement year usually means the year came from the roof's age rather than from its condition.
Why does the roof cost in a property condition report rarely match a contractor's bid?
Because it is usually built from an area measurement and a unit rate, and a real reroof is priced on the things a rate cannot see: the deck, the number of existing layers, the insulation condition, the code work triggered, the access and the equipment that has to be lifted and reset.
- Unit rates describe a straightforward roof on an easy building
- Existing layers may force a tear off rather than a recover
- Wet insulation adds removal and disposal nobody budgeted
- Current code can require insulation and edge work on reroofing
- Access, plant and occupancy drive real costs invisibly
Treat the figure as a placeholder until somebody has looked at the assembly. The gap between a rate based number and a bid is not a rounding error on a large roof, and it falls on whoever owns the building when the work happens. If the reserve line is material to the deal, the cheapest correction is a condition survey that establishes the number of layers, the state of the insulation and whether the deck is sound.
How long is a property condition report useful for?
The observations age quickly and the conclusions age slowly. A roof walked in a dry season and reported as serviceable can have opened up by the following winter, while the system type, the number of layers and the deck construction stay true for as long as nobody reroofs the building.
- System, layers, deck and area remain valid between reports
- Condition findings and photographs date within a season or two
- Any remaining life figure counts down from the inspection date
- A storm between then and now voids the condition narrative
- Lenders usually want a report issued within a set recent window
Keep the durable half and refresh the rest. When a deal stalls and restarts, or a lender asks for an update, the sensible request is a reinspection of condition against the original scope rather than a fresh assessment from nothing. That keeps the comparison honest, because two reports written to the same divisions and the same rating scale can be set against each other, and two written to different ones cannot.
What should I ask for about the roof before the report is issued?
Four things, all of which are easier to add in draft than to argue about later: the roof divided into areas rather than treated as one, a rating against a stated scale, the evidence behind any remaining life figure, and a plain list of what was not accessed and what that leaves unknown.
- Each roof area identified separately with its own age and condition
- A rating defined against a scale printed in the report
- The basis for remaining life stated, not just the number
- Photographs keyed to locations on a roof plan
- A limitations list naming what was not reached and why
Ask while the report is in draft. Assessors expect comment at that stage and the additions above are mostly a matter of presenting work already done. The one that sometimes requires more effort is the division into areas, and it is also the most valuable, because a building with roofs of three different ages has three different replacement years and a single blended figure hides all three.
