Black & White Facilities / Service brief
Liquid-Applied Roofing
A roof crowded with pipes, plant bases and awkward upstands, or one whose surface is ageing but whose structure is sound, may be a candidate for a liquid-applied membrane. Note when the defects appeared, whether they recur and whether anything has changed on the roof recently. That history helps decide between a coating, a repair and a fuller renewal.
What the work can include
- Substrate checks and compatibility with the proposed system.
- Surface preparation and treatment of upstands, outlets and penetrations.
- Application of the specified system to the agreed areas.
The scope states which roof areas are to be coated, what remains untouched and the documentation due at handover. On a multi-building instruction each roof needs its own site and location reference so costs and follow-on actions stay with the right asset.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.
Important decisions
Whether a liquid system is suitable depends on the existing roof's condition, the moisture within it and the product proposed; coating over a wet or unstable build-up hides the problem rather than solving it. Cross-reference every defect to what sits beneath it, with repair history and renewal ranking on the building's record.
Before we visit
Describe the roof construction, the existing finish, any condition reports and the penetrations that will need detailing. Site records, operational impact and the approval limit go with the enquiry, as do the local contact and the hours in which the roof can be worked on without stopping critical activity.
How the work proceeds
From the enquiry come two things: the outcome the client needs and the information that already exists. Substrate and compatibility checks then confirm what the roof can accept and where the instruction's limits sit; the agreed method sets sequence, protection and access before application begins.
At completion the coated areas are recorded against the site or roof reference, the result noted and any outstanding action logged apart from the finished work. That record informs the maintenance plan and the next budget.
What affects cost and timing
Preparation, the reinforcement needed at details, weather during application, curing windows and access determine resources, sequence and duration. A photograph or an estimated area will not fix them on its own.
Where the instruction spans several sites, the tasks and access assumptions behind each have to be tested for consistency before a programme is built from them. Agree temporary operating arrangements and when extra work returns for a decision.
Applications across sectors
Over a warehouse the stock and operations below govern the method; over an office the ceilings and occupied space need protecting; over a school or hotel the application window has to suit the people inside. The sector pages give the full range.
Local coverage
Black & White Facilities covers sites throughout North East England, including Northumberland, Tyne and Wear, County Durham and Tees Valley. Postcode and access details should accompany enquiries for roofs in Newcastle, Gateshead, Durham, Middlesbrough and the other areas listed; the location pages give the detail.
Frequently asked questions
Can a liquid system go over any existing roof?
No. The substrate, its moisture content and its compatibility all have to be checked against the specified product. Some roofs need stripping or other repairs before a liquid system is appropriate.
What information helps scope liquid-applied roofing?
The roof construction, the existing finish, condition reports and details of the penetrations, with the result you are looking for and any dates that constrain access. Earlier survey findings let the assessment pick up where the last left off.
What has most effect on price and programme?
Preparation, detail reinforcement, weather, curing time and access. Proposals only compare like for like when each is priced against the same list of preparation, access and completion activities.
How should the finished work be recorded?
Under the site and work reference, with the areas coated or components changed and any remaining action; where the work stopped short of full scope, note that as a distinct item so completed and incomplete work stay apart.
Guides and useful reading
The roofing planning guide covers preparation and decision points for this service, and repair versus replacement helps decide whether coating, repairing or renewing an ageing roof better balances condition, cost and disruption.
Application work on a roof falls within HSE roof-work guidance, which gives the wider context.
Related services and your enquiry
This service is one of the Roofing family, alongside Metal and Sheet Roofing, Pitched Roofing and Roof Access and Safety Systems. All services, maintenance, projects, sectors and locations cover the wider requirement.
Contact Black & White Facilities with the site reference, the operational priority, who is authorised to instruct and which records exist. Roof construction, existing finish, condition reports and the penetrations to be detailed, where known, mean the next step is scoped against the roof as it is.
