A roof inspection finds and records defects. A roof repair fixes them. They are separate pieces of work with separate skills, and the decision that shapes the outcome is made before either starts: whether the firm writing the defect list is also the firm quoting to work through it.
Neither arrangement is wrong. A contractor who inspects and repairs is quicker and often cheaper, because one mobilisation covers both. An inspector with no repair arm produces a list that nobody profits from, which is what you want when the list will go to a board, a lender or an insurer. What causes trouble is not choosing deliberately.
Three ways to arrange it
| Arrangement | What it suits | What to watch |
|---|---|---|
| One firm inspects and repairs | Routine maintenance on roofs you know | The incentive to find work, and the scope nobody checks |
| Inspection only, repairs tendered | Budget decisions, capital planning, disputes | Slower, and the report has to be good enough to price |
| Inspection then approved repair list | Portfolios and annual programmes | Keeping the approval limits current |
Most owners use the second for anything that will be read by somebody outside the building and the first for everything else. Roof inspection company: how to choose one sets out the four kinds of firm behind that table.
The report has to be priceable
The difference between the two arrangements only exists if the inspection report can be priced by a contractor who was not there. That is a test you can apply to any sample report before you book, and it is the single most useful question to ask a prospective inspector: can another firm quote from this without a second visit?
A priceable defect line carries five things. Where it is, on a plan or a numbered area. What is wrong with it. What happens if it is left. How soon it needs doing. And what the work involves, in enough detail to be costed. Reports that say the flashings need attention fail all five at once.
Priority, not a flat list
A defect list without priorities moves the decision back to you, usually at the point when there is money for some of it and not all. Ask for three bands and nothing more complicated: work that cannot wait, work for this budget year, and items to watch and photograph again next time.
That last band is the one owners cut and should not. A split that has not moved in two years is information. A split that has doubled is a different roof, and only the record shows which you have. Commercial roof inspection services covers what a programme keeps between visits.
Priorities also protect the budget from the opposite failure, which is doing everything at once because the list arrived as one document. Most roofs have two or three items that matter this month and a dozen that do not, and the second group is cheaper to deal with when it is planned rather than when it is urgent.
Emergency work is the exception
When water is coming in, the order reverses: make it safe, record what you did, then work out what caused it. Temporary work done in weather is not a repair and should never be treated as one in the file. Post storm roof inspection covers the sequence after an event, including photographing the temporary work before anything permanent covers it.
What to agree before anybody goes up
- Who writes the defect list and whether they may quote the work
- A value limit for small repairs carried out on the visit
- That every same visit repair is photographed before and after
- Whether a manufacturer warranty restricts who may touch the roof
- Who owns the report and the photographs afterwards
Settle those five in the quote rather than on the roof. Roof inspection service sets out what a single visit covers and what comes back with you, which is where the first and the last of those usually gets decided.
Where to go next
If the roof is under a programme rather than a single visit, annual roof inspection programmes covers how the repair list is carried between years. If the repairs are starting to look like a replacement, get the remaining life question answered before approving either.
Common questions
Does the inspection fee come off the repair price?
Sometimes, and it is worth asking before you book rather than after. Where a firm credits the fee against work it carries out, the arrangement is reasonable as long as the report would read the same whether you accepted the repair or not.
- Ask whether the credit applies to any work or only theirs
- Ask what happens to the credit if you use another contractor
- A credit on a small fee changes very little either way
- A large credit is a discount on the repair, priced in
- Get the arrangement in the written quote, not in conversation
The reason to ask early is that the answer tells you how the firm thinks about the inspection. A company that treats the fee as the price of the report will credit a little or nothing and will not mind being asked. A company that waives it entirely has decided the report is a sales cost, which is fine as long as you read the recommendations knowing that. Neither is wrong. Only one of them produces a document you can put in front of a third party.
What should a repair recommendation in the report contain?
Enough for another contractor to price it without going back up on the roof. That means a located defect, what is wrong with it, what happens if it is left, a priority, and a described scope of work. A recommendation without those five is a sales note.
- Location tied to a roof plan or a numbered area
- The defect itself, photographed and described
- The consequence of leaving it, stated plainly
- A priority: urgent, this season, or monitor
- A scope specific enough to price against
The test is simple to apply. Hand the report to a contractor who has never seen the building and ask for a price. If they can give one, the report is a working document. If the first thing they say is that they need to look at it, you have paid for an opinion rather than a specification, and you will pay again to get the thing you thought you bought.
Can repairs be made during the inspection visit?
Small ones often can, and they should still be recorded. A loose fastener driven home or a lifted flap sealed on the day is sensible work. The risk is the undocumented fix, where something is quietly put right and nobody can tell later what the roof was like before.
- Agree in advance what may be done without approval
- Set a value limit on same visit work
- Require a photograph before and after each fix
- Keep the item on the defect list, marked complete
- Anything structural waits for a priced scope
Two reasons to insist on the record. The first is the warranty: a manufacturer system can be voided by work carried out by an unapproved contractor, and a repair nobody wrote down is the hardest kind to defend. The second is the trend. The value of inspecting the same roof every year lies in comparing one report against the next, and a defect fixed on the day and never recorded breaks the comparison.
How do I stop a repair list growing into a replacement quote?
By asking for the two to be priced separately and by requiring the replacement case to be argued from the roof, not from the list. Repairs that keep a sound roof going and a replacement that ends its life are different decisions, and a single document that slides between them is doing neither well.
- Ask for repair cost and replacement cost as separate figures
- Ask what the repairs buy in years, in writing
- Ask whether the insulation beneath has been tested
- Compare annual repair spend against replacement over its life
- Get a second view before approving a replacement
The honest version of this conversation has a number in it. Repairs that cost a fraction of a replacement and add several years are good value, and repairs approaching half the cost of a new roof usually are not. What makes the comparison possible is knowing whether the deck and the insulation are wet, because a roof with saturated insulation cannot be repaired back to a dry one at any price.
Who warranties a repair found by somebody else's inspection?
The contractor who carries out the repair warranties their own work, and only their own work. An inspector who recommended it warrants nothing about the repair, and a manufacturer system warranty covers neither unless the repair was done by an approved contractor to an approved detail.
- The repairing contractor's warranty covers that repair
- Ask for the term and what it excludes, in writing
- Check whether a system warranty is still in force first
- Unapproved work can void a manufacturer warranty
- Keep every repair record with the warranty paperwork
The order of those questions matters on a roof still inside a manufacturer warranty, because the cheapest competent repair can be the most expensive thing you ever do to it. Establish what warranty exists and who is allowed to touch the roof under it, then commission the repair. Doing it the other way round has cost owners a twenty year warranty for the price of a day's work.
