Roof Inspection Costs UK: Prices & What's Included

Q: Should I charge for a roof inspection?

Yes. Free inspections are loss-leaders that devalue your time and the deliverable. Even a "free" walkaround should be priced at £180-£300 with a credit toward subsequent works. This signals professionalism and ensures the work pays for itself if the customer does not proceed.

Q: Do I need professional indemnity insurance for inspections?

Strongly recommended. If you write a report stating "the roof is in good condition" and the buyer relies on it, you can be sued if the roof subsequently fails. PI insurance covers professional negligence claims; £1m cover costs £400-£900/year for a typical sole-trader roofer.

Q: Can I use a drone for inspections instead of going up?

Drones complement but do not replace physical inspection on most jobs. They cannot lift tiles, inspect under-flashings or feel for soft spots. CAA registration and operator qualification (A2 CofC or GVC) are mandatory for commercial drone work over 250g.

Q: How long should a roof inspection take?

A quick visual inspection on a typical 80-100m² semi-detached roof is 30-60 minutes including access setup. A comprehensive survey including loft and detail photography is 2-4 hours. Pre-purchase legal inspections often take 3-5 hours including the report-writing. Drone inspections add ~30 minutes of flight time plus pre-flight planning.

Q: What should a roof inspection report include?

Cover page with inspector details, executive summary, roof material identification, age estimate, itemised defect list with photos and severity, recommended actions, indicative costs, limitations (what couldn't be inspected and why), PII details, signed and dated. Always include weather conditions on the day of inspection — defects may not be visible in dry weather.

Summary

A roof inspection is a deceptively profitable product line for an established roofer. The work is short, the materials cost is zero, and a structured report with photographs becomes a quotable asset for any subsequent repair or replacement. Many sole-trader roofers charge nothing for an inspection if it leads to a quote; this leaves significant money on the table and devalues the inspection itself in the customer's eyes.

Pricing depends on three things: access (ladder vs tower vs scaffold vs drone), report depth (verbal walkaround vs written report vs full survey for legal/insurance use), and turnaround (same-day vs 1-week). Builders should publish a clear schedule of inspection fees on quote stationery so customers see the value before booking.

This guide covers the four common inspection types — quick visual, comprehensive survey, pre-purchase/legal, and post-event (storm, fire, damp) — and the documentation that distinguishes each.

Detailed Guidance

Inspection Type 1 — Quick Visual

The simplest product: 30-60 minutes on site, photos taken by phone, verbal summary delivered on the day, no written report. Suited to customers who already suspect a specific problem and want a professional opinion to inform their next step.

Deliverables:

8-15 photographs sent via WhatsApp or email same day
One-paragraph email summary identifying defects observed
Indicative repair cost range (not a formal quote)
Recommendation: repair, full survey, or replace

Cost: £180-£300 typical. Some firms waive the fee if the customer proceeds with quoted works; others charge as a separate line and credit on the works invoice. Latter is more profitable and more honest.

Inspection Type 2 — Standard Written Report

The bread-and-butter survey product. 1-2 hours on site, structured written report with photographs, indicative cost ranges for any remedial work recommended.

Report structure:

Cover page — property address, date, inspector name and qualifications
Executive summary — overall condition (good/fair/poor), urgency rating
Roof coverage — material identified, estimated age, life remaining
Defects observed — itemised with photographs and severity (immediate / 1-5 years / monitoring)
Recommended action — repair, partial replacement, full replacement
Indicative costs — ranges only; "estimate not quotation"
Limitations — areas not accessible, weather affecting inspection, parts that couldn't be inspected
Inspector qualifications and PI insurance — signed and dated

Cost: £280-£500. Turnaround typically 3-7 working days. Used by customers planning capital works, by landlords for periodic condition checks, by buildings insurance for renewal documentation.

Inspection Type 3 — Comprehensive Condition Survey

A deeper inspection used before a major roof refurbishment, a re-roof decision, or a high-value sale. Allows 2-4 hours on site with full access (scaffold or tower if needed), detailed photographic record, and a multi-page written report with specific repair recommendations.

What it adds over standard:

Loft inspection — under-roof condition, deck staining, insulation thickness, ventilation
Rafter and ridge inspection — timber condition, sag, splitting, woodworm
Chimney and lead work — detailed inspection of all flashings, sealing, condition
Valleys, hips, abutments — close inspection of all junction details
Gutters and rainwater goods — clearance, fall, downpipe condition
Specific cost estimates — broken down by category and indicative scope of works

Cost: £450-£900. Turnaround 5-10 working days.

Inspection Type 4 — Pre-Purchase / Legal

When a prospective buyer requires a roof report as part of conveyancing, mortgage application, or buildings insurance, the inspection becomes a legal document. The report may be relied on by third parties (lender, solicitor, insurer) and the inspector carries professional liability.

Requirements:

Inspector must hold professional indemnity insurance (typically £1m-£5m)
Report must include scope limitations clearly stated
Comparable to RICS Level 2 (HomeBuyer) standard for the roof element
Often issued alongside a full RICS Building Survey, focused on the roof specifically
May require structural engineer input for sagging or distorted roofs

Cost: £700-£1,500. Most general roofers should not offer this product unless qualified — a chartered surveyor or member of a roofing trade body with PII coverage is the right provider.

Inspection Type 5 — Drone Survey

Drone surveys are increasingly used for high or inaccessible roofs, large commercial premises, or where rapid turnaround is needed. The operator must hold CAA registration and an A2 Certificate of Competency (CofC) or GVC for the relevant operational category.

Process:

Pre-flight risk assessment (over-flight of property, distance to people, distance to vehicles)
Permission from neighbouring properties if drone overflies them
Flight in dry, low-wind conditions (typically <15 mph)
High-resolution photos (24-48 MP) of full roof
4K video walkthrough
Thermal imaging upgrade £200-£400 — useful for identifying leaks and insulation defects
Report integrating drone imagery with ground-level inspection

Cost: £350-£650 for standard; £550-£900 with thermal imaging. Limitations: cannot directly inspect ridge, chimneys close-up, or lift lifted tiles (no replacement of physical access). Drones are a complement, not a substitute, for hands-on inspection on most jobs.

Inspection Type 6 — Storm Damage and Insurance

When a customer suffers storm damage and needs to make a buildings insurance claim, the inspection must produce evidence that meets the insurer's requirements.

Insurer requirements typically include:

Photographs of damage taken within 7 days of the storm
Photographs showing pre-existing condition (if possible — older inspection reports help)
Written description of damage and cause
Quote for remediation, broken down by item
Statement that damage is consistent with the storm event (i.e. not pre-existing wear)
Date and weather record cross-reference (Met Office data showing the storm event)

Cost: £200-£500. Insurers typically accept the inspector's photographs and report; some insurers send their own loss adjuster who may dispute findings. Always cooperate with loss adjusters and provide additional photographs/evidence if requested.

Heritage and Listed Building Inspection

For listed buildings, conservation area properties, or planning-sensitive sites, a roof inspection often forms part of the listed building consent application. Requirements include:

Like-for-like material identification
Slate or tile pattern documentation
Detail photographs of historic features (lead work, finials, decorative tiles)
Conservation officer interaction (some councils require their officer to inspect)
Listed building consent application supporting documentation

Cost: £800-£1,800. Time-sensitive — listed building consent applications take 4-12 weeks before works can start.

Pricing as a Standalone Service

Many roofers undercharge for inspection because they see it as a sales tool. This is wrong. A written report:

Has independent value to the customer
Reduces post-job disputes about what was discovered vs. what was scoped
Is required by lenders, insurers and solicitors regardless of who does the work
Justifies the quote that follows

Pricing structure: charge full inspection fee, credit a percentage (typically 50%) against any subsequent works invoice up to a 3-month limit. This monetises the inspection while incentivising the customer to proceed.
