Asbestos cement roofing across Birmingham’s industrial stock
Walk around Birmingham’s older industrial estates, the workshops and warehouse units, and you’ll see a lot of asbestos cement roofs. The stuff went up in volume through the 60s, 70s and 80s because it was cheap, fire resistant and quick to fix. That’s why so much of it is still sitting overhead today. If you own or run one of these buildings, that roof isn’t just a maintenance question, it’s a compliance one.
Asbestos cement is a lower-risk form of the material, as long as it stays sound. The fibres are locked into the cement. They only become a problem when sheets get cut, drilled, broken, or left to weather until the surface starts to release them. For any duty holder, the question is simple: what condition is your roof actually in, and what does that mean you need to do?
The duty to manage: what the 2012 Regulations ask of you
The Control of Asbestos Regulations 2012 say that if you’re responsible for a non-domestic building, you have a legal duty to manage any asbestos within it. That means finding it, logging its condition in an asbestos register, assessing the risk, and keeping a written management plan. For an asbestos cement roof that’s still in decent nick, the regulations don’t demand you rip it off. They demand you manage it, monitor it, and keep it safe so nobody’s at risk.
Encapsulation fits right into that framework. A properly encapsulated roof is sealed, weatherproofed, and easier to inspect. The work gets recorded as part of your management plan. For a lot of Birmingham building owners, it’s the most sensible and proportionate way to meet the regulations.
What encapsulation involves
Encapsulation means sealing the sheet surface under a coating system designed specifically for asbestos cement. It locks down those fibres and shuts out the weathering that breaks the material down. Done right, it’s a controlled, systematic process:
- We start with a condition survey of the roof, before we recommend anything.
- Controlled cleaning and moss removal. Never dry abrasion or open jet washing.
- Repairs to fixings, flashings and individual damaged sheets, if that’s what’s needed.
- Application of a coating system matched exactly to asbestos cement substrates.
- Updated records for your asbestos register and management plan.
Compared to stripping and re-sheeting, encapsulation usually costs less, causes far less hassle, and you avoid full-roof asbestos disposal charges. Crucially, the building can often stay in use while we work. For an occupied unit on a busy Birmingham trading estate, that last point often makes all the difference.
When encapsulation is not the right answer
We’ll be straight with you: encapsulation only works on sheets that are fundamentally sound. If a roof is badly cracked, delaminating, soft, or friable, coating it doesn’t make it safe. All it does is hide a failing material under a new surface. If your roof is in that state, the right way forward is removal by a licensed asbestos contractor, then re-roofing. We won’t coat roofs that should be removed, and we’ll tell you plainly if yours falls into that category.
The same goes for roofs with widespread impact damage or a history of uncontrolled jet washing. If the damage is localised, we might still be able to replace individual sheets and encapsulate the rest. But that’s a judgement we make on the roof, not from the ground.
Survey first, always
Every job we do starts with a survey. We never guess a quote from a postcode. We’re based in the South East but we work across the whole UK, including Birmingham and the wider West Midlands. That survey is what tells us whether encapsulation, a partial repair, or full removal is the honest recommendation for your building. If you’re looking at an ageing asbestos cement roof on an industrial unit, workshop, or agricultural building, ask us to take a look before you commit to anything.
