Asbestos, Roofing and Retrofit: Getting the Work in the Right Order
Check the whole project before the first fixing.
Roofing, scaffolding, solar and refurbishment teams can all disturb the same building. Bringing their plans together helps asbestos information reach the right people before work begins.
AI-generated illustration of a pre-works planning visit. This is not a photograph of a named ASM or F&I Group project.
What should come first: the asbestos survey, scaffolding or roof works?
Agree the combined work scope first, then establish suitable asbestos information before any affected building material is disturbed. There is no universal sequence: safe access may be needed to complete an inspection, but scaffold ties and other fixings must not disturb suspect materials before their asbestos status and the necessary controls are resolved.
For roofing and retrofit, the investigation needs to follow the work beyond the roof covering: think about soffits, concealed layers, service routes, ventilation openings and the fixings for new equipment.
One building programme can create several asbestos interfaces
A client may describe a project as a roof replacement, a solar installation or an energy-efficiency upgrade. On site, that same project could involve scaffold anchors, altered roof edges, new cable penetrations, ventilation ducts and replacement internal finishes.
The useful question is not simply, “Do we have an asbestos report?” It is: “Does the information cover every building element that each trade proposes to disturb?” A report can be useful within its original scope while leaving gaps for later design changes or additional trades.
Our recommendation is to bring the drawings and work schedules together before finalising quotations. It gives the asbestos surveyor a clearer brief and gives each contractor the opportunity to identify access, protection, reinstatement and handover requirements early.
HSE advises sharing asbestos information as early as possible for planned work, including when seeking quotations: information for people who might disturb asbestos.
Where each trade should connect with the asbestos brief
These are examples to discuss when scoping a project, not a claim that every material listed contains asbestos. The investigation should reflect the actual building and proposed disturbance.
Roof replacement and roofline work
Look beyond the visible covering. Identify which soffits, undercloaks, boards, insulation, gutters and adjoining wall components will be removed or penetrated. Agree who leaves the building weatherproof between packages.
Possible Group route: ASM, the appropriate asbestos-removal team, John Flowers or John Flowers Flat Roofing.
Scaffolding and temporary access
Mark proposed tie locations, drill points and access routes. Ask whether the access installation itself affects suspect cladding or boards. Where access is needed for surveying, agree a safe enabling arrangement rather than assuming everything must wait.
Possible Group route: ASM and Ingleford Scaffolding, with project-specific access design where needed.
Solar PV, batteries and electrical routes
Include the route from roof equipment to the inverter, battery and electrical connection. Roof fixings, wall penetrations, ceiling voids and equipment mounting surfaces can fall outside a roof-only brief.
Possible Group route: ASM, roofing/access specialists and Flowing Energy Solutions.
Insulation, ventilation and domestic improvements
Identify loft access, boards to be lifted, wall fixings, ventilation openings and affected roofline components. A change intended to improve energy performance can still involve intrusive work to existing materials.
Possible Group route: ASM, Flowing Energy Solutions and, for suitable residential work, Flowing Home Improvements.
Refurbishment and reinstatement
Agree what remains after any asbestos removal: exposed openings, unfinished surfaces, disrupted fire protection or areas needing reinstatement. Define the next contractor’s starting condition rather than assuming removal includes a finished building.
Possible Group route: ASM and Flowing Construction Services for an agreed construction package.
Permanent roof safety and future maintenance
Consider future inspection access and equipment maintenance during design. Proposed anchors, supporting surfaces and penetrations should be coordinated with the asbestos information and roofing specification before installation.
Possible Group route: ASM, the roofing designer and Zenith Safety Systems.
An asbestos result is not a roof-safety assessment
Identifying a roof material does not establish its load capacity, condition or suitability for solar equipment. HSE advises treating roofs as fragile until a competent person confirms otherwise. Structural design, weatherproofing, electrical safety and working-at-height controls require their own competent assessment.
Five checkpoints before one trade hands over to the next
We suggest agreeing these checkpoints with the client and project team. They are planning prompts, not a replacement for the project’s risk assessments, method statements or construction-phase arrangements.
Combine the proposed work into one survey brief
Mark the roof, elevations, rooms, fixings and service routes affected by all trades. Review existing reports against that drawing. Include temporary works and planned opening-up, not only the finished design.
A management survey supports normal occupation; intrusive alterations may need a suitably scoped refurbishment asbestos survey. Targeted sampling can answer a specific material question, but one negative sample does not clear unrelated materials or concealed layers.
Resolve access and information gaps
Agree safe access, isolations and occupation arrangements before inspection. Destructive survey areas must be vacated and confirmed fit for reoccupation before people return. Programme any further investigation needed for restricted locations.
“Not accessed” is not an asbestos-free finding. Do not release work that depends on an unresolved area. Address the gap through further investigation or an appropriately assessed presumed-asbestos approach before disturbance.
Agree the asbestos response and package boundaries
Where asbestos is identified, decide whether the design can avoid it, whether it can remain protected or whether removal is needed. A positive result does not automatically require removal of every asbestos material in the building.
Confirm the appropriate work category, contractor, notification requirements where applicable, waste arrangements and any analytical support. Identify who provides access, weather protection and reinstatement. Agree the next trade’s start conditions in writing.
Release the defined work area on evidence
Do not programme the roofer or installer to start simply because removal was expected to finish that day. Identify the inspection, cleaning, testing and completion records relevant to the actual asbestos work.
Where formal four-stage clearance applies, the required stages must be completed before reoccupation. It is not automatically required for every asbestos-cement roof job, and a reassurance air test is not a substitute. Agree the appropriate air-monitoring and clearance requirements before mobilisation.
Complete the building records, not just the installation
Bring together the survey information, relevant removal and waste records, analytical documentation where applicable, as-built routes and installation handover information. Clearly record any asbestos that remains and any restrictions on future work.
Update the asbestos register and management arrangements where required. Keep the asbestos information connected to the building’s maintenance records and the health and safety file where applicable.
Further guidance: HSE survey scope and access; management-plan review; commercial-client responsibilities under CDM.
A new cable route or fixing location can change the survey scope
A late decision to move an inverter, add ventilation, alter scaffold ties or replace an extra section of soffit can introduce materials that were not included in the original investigation.
Use a simple change-control question: “Does this revision disturb anything outside the agreed asbestos information?” Refer the change back for review before intrusive work proceeds. A completed report should not be treated as permission for an expanding programme.
One starting conversation, with the right specialists brought in
An existing ASM client can bring us a roof, access or retrofit requirement alongside the asbestos brief. Equally, a client already working with an F&I roofing, scaffolding or energy team can ask for ASM to review the asbestos information before intrusive work is planned.
ASM directly undertakes appropriate non-licensed and notifiable non-licensed asbestos work. Where an HSE-licensed contractor is needed, that package can be delivered through Flowing Construction Services within F&I Group. Read our asbestos removal service guide for the appropriate route.
The opportunity is to coordinate compatible work, not to assume every project needs every Group company. You can commission asbestos services alone, retain existing contractors or discuss a wider package. Scope, price, availability, responsibilities and the contracting entity must be agreed for each appointment.
Technical decisions remain impartial
Survey findings and any analytical or clearance decisions must not be driven by follow-on sales. Agree the analytical appointment with the client, disclose relevant commercial links and address conflicts before work starts. Use an independent external UKAS-accredited organisation where required to protect impartiality.
HSE advice on competent surveyors, analysts and accreditation.
Clear roles, not assumed responsibility
Using several Group businesses does not automatically create one contract or appoint ASM as principal contractor. The client, designers and contractors still need clear project arrangements and the appropriate CDM appointments.
UKAS 32982 applies to ASM’s defined inspection/testing scope. It is not accreditation of Group roofing, scaffolding, removal, construction or energy installation.
Leam Lane: several building improvements in one programme
F&I Group’s published Leam Lane case study describes 70 SHDF projects delivered by Flowing Energy Solutions for Bell Group over six months. The stated scope included scaffolding, re-roofing, roofline work, solar PV, insulation, ventilation, environmental cleaning and asbestos removal.
It demonstrates the type of linked programme discussed here. The case study is Group delivery evidence; it does not identify ASM as the survey provider, so we do not present it as an ASM surveying case study.
Two useful conversations to have before tendering
A school roof and ventilation programme
Ask whether the asbestos brief covers the roof edge, ceiling access and new ventilation routes. Plan access and any occupied-area restrictions before the holiday window. Agree what evidence allows each area to pass from asbestos works to roofing and installation.
Illustrative planning scenario, not a named completed project.
A warehouse solar installation
Ask the installer for equipment locations, roof fixings and the full electrical route. Review these alongside the roofing and structural assessments. Establish whether the scope reaches internal boards, service cupboards or wall penetrations that a roof-only inspection would not address.
Illustrative planning scenario, not a named completed project.
For repeat programmes, agree a property-by-property scope and a common handover format. Our property-portfolio service and facilities-management support provide routes for that discussion. Do not assume identical-looking buildings contain identical materials.
What should you send ASM before asking for a quotation?
- The property and existing records: site address, building use, available survey reports, register, relevant drawings and previous removal records.
- The complete proposed work: roofing, access, insulation, ventilation, solar, electrical routes, fixings and any internal alterations.
- Access and programme constraints: occupation, opening-up permissions, isolations, shutdown dates and any known inaccessible locations.
- The delivery arrangement: your project contact, existing contractors and which additional Group disciplines you would like considered.
Tell us what must be ready for the next trade, not just what you would like removed. We can then agree whether an information review, sampling or a project-specific survey is the appropriate starting instruction.

Asbestos, roofing and retrofit FAQs
Does a roof-only asbestos check cover a solar installation?
Not necessarily. The installation may also affect cable routes, equipment mounting surfaces, walls, ceilings and service cupboards. Match the asbestos investigation to the full installation scope, not only the roof covering.
Can scaffolding be installed before the asbestos survey?
Safe access may be needed for the survey. However, ties, fixings and other access work must not disturb suspect materials before suitable asbestos information and controls are in place. Agree the enabling-access sequence with the surveyor and access designer.
Is a management survey enough for roofing or retrofit work?
Only information suitable for the actual disturbance should be relied upon. A management survey may leave concealed materials or project-specific locations uninvestigated. Intrusive alterations commonly require a suitably scoped refurbishment survey.
What happens if the design changes after the survey?
Review the revised work against the surveyed areas and materials. A new penetration, fixing location or service route may require additional investigation before that part of the work can proceed.
Does every asbestos roof-removal job need four-stage clearance?
No. The analytical and completion requirements depend on the asbestos work undertaken. Formal four-stage clearance applies to relevant licensed removal; it is not an automatic requirement for every asbestos-cement roof project. Agree the appropriate assessment and records before work starts.
Can an existing F&I Group client appoint ASM for surveying only?
Yes. The asbestos requirement can be discussed as a separate appointment. Wider roofing, access, construction or energy support is considered only where relevant and agreed with the client.
Does using F&I Group automatically mean one contract?
No. Confirm the legal contracting entity, scope, costs, programme and project responsibilities for each package. Group membership does not automatically transfer supplier approval or create a principal-contractor appointment.
What should the next contractor receive at handover?
The relevant survey information, the defined released work area, applicable asbestos-work completion and analytical records, remaining asbestos restrictions and agreed next-stage controls. Keep the building register and management arrangements updated where required.
