Choose the inspection from the decision it must support
Leak investigation asks where water enters and what repair is proportionate. Condition inspection asks what is visible and what needs attention first. A pre-work survey defines scope. A purchase-related check may inform wider questions, but its professional status and limits must be agreed before reliance.
State the building type, whether the concern is local or whole-roof, and the needed output: verbal observations, photographs, written condition notes or a repair schedule. These are not interchangeable, and this page does not promise every format.
Define the boundary before the visit
A roofing inspection is not automatically a RICS survey, Home Report, valuation, structural report, insurance assessment, expert opinion or statutory certificate. Identify any required qualification, independence or wording first so the correct professional route can be confirmed.
Name the roofs, elevations, voids and connected details in scope, plus whether the purpose is diagnosis, maintenance, quotation support or post-work comparison. A focused inspection need not pretend to answer wider legal, structural or whole-building questions.
Agree a safe inspection method and its limitations
Inspection may combine ground views, internal rooms, an accessible void and closer external viewing where planned access allows. Method depends on height, pitch, fragility, shape, ground and required detail. Remote images show position and pattern but not necessarily fixings or substrate.
Weather can conceal symptoms and build-ups remain hidden beneath coverings. Record the date, conditions, viewpoints, inaccessible areas and whether inspection was non-intrusive. Agree any opening-up, testing or monitoring separately.
Inspect each roof type on its own terms
Pitched checks cover material, visible fixings, ridges, hips, valleys, verges, eaves, flashings, chimneys, windows and internal signs. Flat checks cover membrane, seams, upstands, trims, penetrations, falls, outlets and accessible deck evidence. Map mixed-roof junctions clearly.
Traditional roofs add matching, incompatible repairs, lime mortar, lead and conservation context. Identify sound fabric, possible retention and whether a material or appearance change needs advice beyond the condition report, rather than relying on age alone.
Ask for findings that separate fact, diagnosis and uncertainty
Label direct observations, likely causes and alternatives. Tie photographs to a slope or detail and describe extent and urgency plainly. Record inaccessible areas, dry-weather limits, concealed substrates and ownership or access assumptions because they affect confidence.
Separate make-safe concerns, short-term repair, planned maintenance and monitoring. Options should state what each addresses, connected work and evidence that could change the choice. Confirm whether delivery is site notes, a written report or another format.
Prepare documents, access and the issue history
Provide reports, quotations, repair records, photographs, dates and weather linked to leaks. Give safe access to affected rooms and voids and identify locks, alarms, tenants or restrictions. Do not move insulation, lift coverings or enter an unsafe void.
For shared buildings, include factor or owner contacts and identify common roof areas. Mention deadlines without assuming third-party requirements will be met. Height, extensions, parking, public areas and fragile materials shape access planning.
Route each finding to a proportionate next step
Route pitched defects to repairs, slate, tile, leadwork or chimney work; membrane, outlet or deck concerns to flat roofing; and protected fabric to heritage roofing. Active entry may need urgent enquiry, while structural, valuation, legal or appliance issues need the relevant qualified route.
State the question, property context, evidence and intended reader. Any later proposal should confirm the service scope, output format, access assumptions and current availability. Until then, avoid promising certainty where construction is concealed or implying credentials, independence or report status.
