Booking a roof survey can feel daunting for homeowners, landlords and property managers. This guide explains, step-by-step, what to expect during a professional roof survey so you can prepare, understand the findings and decide on next steps with confidence.
1. Booking and pre-survey checks
Your survey usually starts with a short pre-inspection conversation. The surveyor will ask about known issues (leaks, draughts, recent storm damage), access limitations and whether the property is occupied. Roofing, Roofers and Roofs offers free quotations and will confirm the survey type—visual, invasive or a drone inspection—based on your answers.
- Document check: planning constraints, previous reports or insurance claims if available.
- Access arrangements: keys, ladders, scaffolding needs and parking.
- Health & safety: occupants informed and hazards flagged (asbestos, loose tiles).
2. Arrival and initial walkaround
On arrival the surveyor will do an external walkaround to note obvious issues and roofline condition. This establishes context—gutter performance, fascia and soffit condition, chimney flashings and visible moss or algae growth. Expect quick notes and photographs taken from ground level.
- Checks on gutters and downpipes for blockages or overflow.
- Assessment of rainwater dispersal, nearby trees and vegetation.
- Photographs for the report and insurance records.
3. Roof inspection: safe access and methods
Surveyors use a mix of methods according to risk and roof type. For pitched roofs they’ll often use ladders and lightweight harnesses; for high or hazardous roofs they may use scaffolding or a drone. Flat roofs, felt, EPDM or GRP roofs are inspected on-foot where safe.
- Drone inspection: useful for steep, high or complex roofs and for documenting slate, tile or metal systems; less disruptive and quicker.
- On-roof inspection: checks seals, flashings, ridge and verge, tile/slate condition and ventilation components.
- Internal inspection: a brief look in the loft or ceiling void to check insulation, ventilation, signs of water ingress or staining.
4. What the surveyor will look for
Surveyors have a checklist to spot current problems and future risks. Expect the following to be examined:
- Covering materials: broken or slipped tiles/slates, cracked or blistered membranes, rusted metal sheets.
- Flashings and details: chimneys, skylights and abutments need secure leadwork or alternative flashing.
- Rainwater goods: gutters, downpipes and outlets for leaks, capacity and blockages.
- Ventilation and insulation: roof vents, eaves ventilation, loft insulation levels and signs of condensation or mould.
- Structural signs: sagging timbers, rot, damp patches or compromised decking.
- Age and expected life: an assessment of remaining lifespan and which elements may need work soon.
5. Diagnosing leaks and hidden problems
Not all issues are visible from outside. The surveyor will use the loft space and targeted probing—tap tests, moisture meters or thermal imaging when needed—to find hidden leaks, trapped moisture or insulation gaps. Where external cause is unclear, they may recommend a more detailed intrusive inspection.
- Moisture readings and photos to show ingress locations.
- Identification of patch repairs versus systemic work needed (e.g. full re-roof).
- Advice on timescales for repairs to prevent structural damage or mould growth.
6. The survey report: what it contains and how to read it
After the inspection you will receive a written report and photographs. Good reports are clear and prioritised so you know urgent fixes from recommended maintenance.
- Executive summary: quick view of urgent issues and overall condition.
- Detailed findings: annotated photos, measurements and condition notes.
- Recommendations: repair options, replacement suggestions, materials and expected lifespan.
- Cost estimates: sometimes provided as ranges or a separate quote for works.
7. Next steps and choosing the right work
With the report in hand you can prioritise action. For minor problems, a targeted repair or maintenance plan might suffice; for widespread deterioration, a re-roof or partial replacement could be the most cost-effective long-term solution. Roofing, Roofers and Roofs can provide tailored proposals for repairs, replacements, flat roofing or specialist work such as lead flashing, EPDM or GRP installation.
- Get at least two quotes for major work and compare materials, warranties and timescales.
- Consider preventative options like roof coatings, improved ventilation or insulation to reduce future costs.
- For insurance claims, use the survey report to support your case—survey photographs and dated notes are valuable evidence.
8. Why a professional survey saves money and stress
