A roof inspection, and who is really paying for it
What a proper inspection covers - outside, inside the attic, and the structure - plus the honest problem with the free ones.
What is roof inspection?
A roof inspection is a documented assessment of the roof covering, its flashings and penetrations, the attic below it and the structure carrying it - producing a written report with photographs and an estimate of remaining service life. It takes roughly 45 minutes to a couple of hours on a typical house. The report is only as useful as the inspector's independence from whoever gets the resulting job.
Signs you need roof inspection
- You are buying a house and the roof is the largest unknown number in the purchase
- Your roof has passed the fifteen-year mark and you have never had it looked at
- A significant storm has been through and you want a record of the roof's condition regardless of whether you claim
- Your insurer has asked for a roof condition report or a certification before renewing
- You are selling and want to head off a buyer's inspection finding with your own documentation
- You have a stain, a draught or a recurring ice build-up and want a diagnosis before you get bids
- Trees overhang the roof and you want the wear checked before the next windy season

How roof inspection actually works
Exterior - the covering and everything that penetrates it
The inspector walks the roof where it is safe to, or uses a drone where it is not, and records the condition of the field, ridges, hips and valleys, granule loss, fastener condition, and every penetration - chimney, vents, skylights, satellite mounts.
Watch forA ground-level look with binoculars written up as an inspection. There is a legitimate place for a ground assessment, but it is a triage, not a report, and it should be priced and described as one.
Attic interior - where the evidence actually lives
From below, the inspector looks for daylight, staining on the sheathing and rafters, damp insulation, mould, rust on fasteners and inadequate ventilation. Interior evidence often predates anything visible from above.
Watch forNobody asks to get into your attic. An exterior-only inspection cannot tell you whether water has been getting in, and this is the single most common thing left out of a "free" inspection.
Structure and drainage
Sagging between rafters, deflection along the ridge, spongy decking underfoot, and whether gutters and downspouts are actually taking water away from the building rather than into the fascia or the foundation.
Watch forStructural notes with no photographs. A sagging ridge is a serious finding and a serious expense - it should be documented well enough that a second professional can evaluate it without climbing anything.
A written report you can act on
A useful report separates what needs doing now, what to budget for, and what to monitor; states an estimated remaining service life; and includes dated photographs of each finding. It should be readable by somebody who is not a roofer.
Watch forA report that is really a quote. If the deliverable is a price with photographs attached rather than findings with severity levels, you did not buy an inspection.
The walkthrough
The inspector should talk you through what they found, what it means, and what happens if you do nothing for another year. That conversation is most of the value, and it is where you find out whether they actually went into the attic.
Watch forUrgency introduced during the walkthrough that was not in the report. A finding that needs a decision today has never been a good sign, and it is the standard shape of a storm-chasing pitch.
Certification, where you need one
A roof certification is a separate product: an inspector states a roof is sound and estimates a number of years it should remain so. Lenders and insurers ask for these, and buyers occasionally do.
Watch forTreating a certification as a warranty. It is a professional opinion at a point in time, and it does not obligate anybody to pay for a failure afterwards.
What does roof inspection cost?
A paid independent roof inspection typically runs from the low to mid hundreds, more for drone or infrared work and for large or steep roofs. Contractor inspections are usually free because they are a bid visit. Our cost guide breaks down what each one includes.

When roof inspection is the wrong call
When saying yes is the wrong move:
- You already know you are replacing the roof. If the covering is obviously finished and you have decided, the money is better spent on getting three properly scoped bids than on a report telling you what you already know.
- You want the roofer bidding the job to be your independent assessor. Free inspections are marketing, and a great many of them are honest - but the person performing it is paid only if you buy work. For a decision worth five figures, pay somebody who is not bidding.
- Water is coming in right now. An inspection is a scheduled, documented assessment. Active water entering the house needs stabilising first; book the assessment once the roof is dry.
- A door-knocker offered it after a storm in your area. The free post-storm inspection is the single most common opening move in roofing fraud. If you want the roof looked at, choose the inspector yourself.
- Your roof is under a year old and you have no symptoms. There is nothing to find yet, and the installer's workmanship warranty covers what an inspection would catch.
- You need it purely to satisfy an insurer, and they name their own inspectors. Check the carrier's requirements first - an inspection they will not accept is money spent twice.
Types of roof inspection
What to check when hiring for roof inspection
- Are you also going to bid on any work you find? Not disqualifying, but it changes how you read the report. Ask it first, and ask it plainly.
- Will you go into the attic? The fastest way to sort real inspections from bid visits. Half the evidence of a leaking roof is on the underside of the deck.
- What do I receive at the end - and can I see a sample report? A sample tells you in thirty seconds whether you are buying a document with findings and severity levels, or a quote with photographs.
- Will you estimate remaining service life, and on what basis? The number you actually need for planning. An inspector who will not put one on paper is not giving you much to work with.
- Do you walk the roof, or inspect by drone - and which applies to mine? Both are legitimate. Steep, tile, slate and wet roofs are often drone-only for good safety reasons, and knowing which you are getting sets expectations for what can be assessed.
- What certifications or licences do you hold? Roof inspection is not licensed uniformly across states. Ask what the credential is and who issues it, then check it - the answer is verifiable in a minute.
- How long do the findings stand for, if I need to show them to an insurer or a buyer? Reports have a practical shelf life, and one storm can invalidate a six-month-old assessment. Ask before you rely on it in a transaction.
