CHAS Advanced · NFRC · Reset Compliance 01 — What a survey deliversA written record of the roof, not a quote in disguise.
A roof survey is a documented assessment of the roof's condition, defects, materials and remedial priorities. It is not a quotation. The output is a written report that the client can use independently — for budget approval, insurance discussion, capital programme planning, procurement of a replacement project or simply to know what state the roof is in.
Most commercial roofs need a survey before any meaningful procurement decision can be made. Pricing roof work from a photograph is unreliable; pricing from a written survey with photographic evidence is professional. Evenii separates the survey work from the repair work so clients are not paying for a sales pitch.
The survey output is owned by the client. There is no obligation to instruct Evenii for the remedial work — although many clients do, because the building is now known and the specification flows naturally from the survey findings.
02 — What the report coversStandard sections of a written condition report.
Building & access
Building location, roof areas surveyed, roof types, access method used (ladder, scaffold, MEWP, drone where appropriate), safety constraints encountered and any areas the survey could not reach.
Scope · access · constraintsCondition narrative
Written description of the roof condition area-by-area, in plain English. Slate or tile state, membrane condition, flashings, drainage, penetrations, plant areas, edge detail and visible defects.
Narrative · plain EnglishDefect list
Structured list of identified defects with photographic references. Each defect carries a priority band (urgent / planned / monitoring) and a brief recommendation.
Defects · priorities · recsPhotographic appendix
Dated, captioned photographs cross-referenced to the defect list. Wide-context shots and close-detail shots. Supplied as part of the report PDF; raw photos available on request.
Photos · evidence · referencedIndicative costs
Where appropriate, indicative cost banding against remedial items. Bands rather than exact figures, because a survey is not a quotation. Helps with budget planning and capital programme prioritisation.
Bands · budget · prioritisationRecommendations
Short concluding section: whether to repair, replace, monitor or commission a more detailed survey of specific roof areas. Honest about uncertainty where it exists.
Repair · replace · monitor 03 — Who commissions surveysThe procurement reader for a roof survey.
Roof surveys are commissioned by buyers who need a documented record before making a decision. NHS estates teams commissioning surveys ahead of capital programmes. Schools and academies commissioning surveys for budget approval cycles. Housing associations commissioning surveys for stock condition data, disrepair claim defence or planned investment.
Local authority property officers commission surveys for civic estate management. Property management firms commission surveys on portfolio properties to support tenant relationships, lease decisions and insurance discussions. Insurance loss adjusters commission surveys to confirm the scope of damage following storm events.
Some surveys are one-off — a single building, a single decision. Others are part of a wider programme — multiple buildings, repeat visits, condition tracking over time. The survey scope and report format are sized accordingly.
04 — How a survey is deliveredFrom enquiry to report.
01
Enquiry
Building location, roof type if known, reason for the survey (capital programme / insurance / planned investment / one-off), access position and any time-sensitive context.
02
Attendance
Surveys are typically completed within five working days of instruction. Attendance routes are chosen for safe roof access — ladder, scaffold, MEWP or drone where appropriate.
03
On-site survey
Roof areas surveyed in a documented order. Photographs taken throughout. Notes on defects, access constraints and any areas that could not be safely reached.
04
Report drafting
Survey notes turned into the written report — condition narrative, defect list, photographic appendix, indicative costs where appropriate, recommendations. Typical turnaround is 5–10 working days from site visit.
05
Delivery
Report supplied as a PDF. Follow-up call to walk through the findings is offered. If remedial work is required, the report becomes the basis for specification — either by Evenii or by another contractor.
05 — Drone surveysWhere drones are useful — and where they aren't.
Drone roof surveys are appropriate for specific situations: large roof areas where ladder or MEWP access is impractical, listed-building work where physical access risks the fabric, high-rise pitched or flat roofs, and rapid condition overview surveys across a portfolio.
Drones are less useful for surveys that need physical touch — checking whether a tile is loose, lifting a flashing to inspect the underlay, or testing whether a roof outlet is partially blocked. The honest position is that drones complement a physical survey rather than replace it. The report will identify which findings were established remotely and which were verified physically.
