Black Country industrial roofs are full of asbestos cement
Wolverhampton’s manufacturing heritage shows in its roofline. The factories, foundries, workshops and large warehousing units that fill the city and the wider Black Country were, for decades, roofed in corrugated asbestos cement as a matter of course. Most of that sheeting dates from the 1960s to the 1980s, the boom years for this kind of industrial building. The roofs were typically given a working life of around thirty years; many have run well past it. The result locally is a stock of large portal-frame roofs that are porous, moss-laden and leaking at fixings and laps, even where the sheets themselves remain structurally sound. That condition is exactly where encapsulation earns its place, and exactly where a careful survey is needed to confirm the sheets really are sound.
Why encapsulation usually undercuts removal
On a large industrial roof, the maths matters. Encapsulation is an engineered process: the roof is surveyed sheet by sheet, cleaned under controlled conditions so moss and debris come away without releasing fibres, then repaired at the fixings and rooflights before a coating system designed for asbestos cement is applied. The cured film binds the surface, locks fibres in, restores water-shedding and extends service life. Set against stripping a large warehouse roof, disposing of every sheet as hazardous waste and paying for a full replacement, the cost difference is usually substantial. Crucially, the unit underneath stays operational, which on a working industrial site is often worth as much as the headline saving when you factor in lost production and disruption.
The duty to manage under CAR 2012
Regulation 4 of the Control of Asbestos Regulations 2012 places a duty to manage asbestos on whoever controls maintenance of non-domestic premises. You are required to identify asbestos-containing materials, assess their condition, keep a written record and manage the risk on an ongoing basis. The duty is to manage, not to remove for its own sake. Asbestos cement in sound condition can stay in place provided it is recorded, monitored and sealed where that makes sense. Encapsulation is a recognised way to meet that duty: a planned, documented control measure inside your asbestos management plan rather than a shortcut around it.
The honest limit: where removal is the only answer
Not every roof should be coated, and we say so before a survey rather than after a failure. Encapsulation is wrong where sheets are widely cracked or holed, where the cement has turned soft and friable through long saturation, or where structural movement and storm damage have compromised the roof. It also applies only to asbestos cement. If a survey finds asbestos insulating board, lagging or sprayed coatings, that material is licensable and must be removed by an HSE-licensed contractor, not sealed over. When removal is the right route for your building, we put it in writing and decline the coating rather than take on work that will not last and would put your compliance at risk.
Survey-led, England-wide, Wolverhampton covered
We work from a South-East base and cover England, so Wolverhampton and the Black Country fall well inside our survey area. Every job begins with an inspection, not a sales pitch:
- A condition survey of sheets, fixings, rooflights, gutters and structure
- A photographic record for your asbestos management plan
- A plain written recommendation: encapsulate, repair first, or refer for removal
- A specification and price only where coating is genuinely appropriate
- Workmanship carried out under controlled, documented conditions
If you run an industrial or warehouse building with a 1960s-to-1980s asbestos cement roof that has never been assessed, the survey settles the compliance position and the cost question in one visit, and tells you honestly which of the three routes the evidence supports.
