A commercial roof condition survey is a planned visual inspection of a commercial building's roof, recording its current state with photographs before problems become emergencies. City Building and Roofing Ltd survey flat and pitched commercial roofs across London and Surrey, prioritise visible defects, and provide maintenance recommendations that landlords, managing agents and facilities teams can budget against.
What a commercial roof survey involves
Commercial roofs fail expensively and rarely conveniently. A planned condition survey replaces guesswork with a documented, photographed record of the roof's actual state — coverings, drainage, rooflights, plant penetrations and edge details — reviewed by roofers who repair these roofs for a living.
The output is practical rather than academic: a photographic schedule of the roof, a prioritised list of visible defects, and clear recommendations separating urgent repairs from planned maintenance and items simply worth monitoring.
Surveys suit landlords, managing agents, facilities managers and business owners responsible for offices, retail units, schools, warehouses, industrial premises and residential blocks with communal roofs.
When to commission a survey
- You are budgeting next year's maintenance and need real information about the roof
- A lease event, dilapidations discussion or property purchase requires evidence of roof condition
- Tenants report recurring leaks and piecemeal patching is no longer working
- The roof has never been formally inspected and its age or history is unknown
- You manage multiple properties and want a consistent photographic record across the portfolio
What the survey covers
Roof coverings
Felt, single-ply, asphalt, metal or tiled coverings — splits, blisters, ponding, corrosion, slippage and general ageing.
Drainage and outlets
Gutters, internal outlets, downpipes and overflow provision — the most common cause of commercial roof damage is simply blocked drainage.
Details and penetrations
Upstands, rooflights, plant bases, cable and pipe penetrations, expansion joints and edge trims where most leaks start.
Photographic schedule
Dated photographs of every roof area and defect, giving you a baseline record for future comparison and for contractors quoting work.
Defect prioritisation
Findings ranked into urgent, medium-term and monitor-only categories so budgets go where they matter.
Maintenance planning
Practical recommendations — clearance cycles, minor repairs, localised recovering — to extend the roof's serviceable life.
How It Works
Scope and access
We agree the buildings and roof areas to survey, and the access and safety arrangements each roof requires.
The survey visit
We inspect the roof areas visually, photograph coverings, drainage and details, and note every visible defect.
Optional drone or thermal support
Where suitable, drone photography covers large or inaccessible areas and thermal imaging can assist moisture investigation — availability confirmed per site.
Reported findings
You receive the photographic schedule with prioritised defects and plain-English maintenance recommendations.
Quotations where needed
Where repairs are recommended, we provide itemised written quotations — with no obligation to use us for the work.
Scope and limitations
- This is a visual condition survey of accessible roof areas; it does not include opening up, core sampling or structural calculations
- Concealed defects beneath coverings or within the deck cannot be seen and may only emerge during repair work
- Access and safety arrangements can limit which areas are inspected — anything not accessible is recorded as such
- Drone and thermal support depend on site conditions, weather and suitability, and are confirmed per building
We would rather tell you the honest position than win work on promises we cannot keep.

Frequently Asked Questions
How often should a commercial roof be surveyed?
As a general rule, a visual check every year — ideally after autumn leaf-fall or winter storms — keeps drainage clear and catches defects early, with a fuller photographic survey every few years or after significant weather events. The right frequency depends on the roof's age, covering and history, which the first survey establishes.
Do you survey occupied buildings?
Yes. Most of our commercial surveys are on occupied buildings. The work is external and non-disruptive; we agree access arrangements with your facilities team or managing agent and comply with the site's safety procedures.
Can the survey be used for dilapidations or lease discussions?
The photographic schedule and defect record provide dated, factual evidence of roof condition, which surveyors and solicitors frequently use to inform dilapidations and lease-end discussions. We report condition as roofing contractors; formal dilapidations assessments remain the domain of your building surveyor.
What does a commercial roof survey cost?
It depends on the size of the roof, the number of buildings, access requirements and whether drone or thermal support is useful. We confirm a fixed written price before attending, and multi-building portfolios are priced accordingly.
Do you also carry out the repairs?
Yes — we are a roofing contractor first, so survey findings translate directly into itemised quotations for any recommended work. You are under no obligation to use us for repairs; the survey and its photographic record are yours either way.
Can you survey a roof we cannot access ourselves?
Usually. Between ladders, towers and drone photography where conditions and airspace allow, most roofs can be assessed safely. Where a specific area genuinely cannot be reached or flown, the report says so rather than guessing.
