The problem
Our asbestos encapsulation system provides a safe, compliant and cost-effective way to protect ageing asbestos cement roofs and extend their working life by up to a further 20 years.
Rather than removing and replacing the existing roof, we carefully clean, prepare and encapsulate the asbestos cement sheets, creating a durable, weatherproof and leak-resistant barrier that protects the roof for years to come.
We use a specialist closed-head cleaning system and steam technology to safely prepare the roof surface, with waste captured and passed through advanced filtration to minimise the risk of contamination throughout the process.
Once prepared, we apply our Nano-Tech Advanced Coating system, sealing the asbestos cement and providing long-lasting protection against weathering, water ingress and further deterioration.
The solution
We can also carry out associated roof works as part of the same project, helping you deal with multiple issues in one planned programme. This can include:
This means you don't have to coordinate multiple contractors to get your roof back into a safe, serviceable and weather-resistant condition.

What we do
ASL also treats metal and cladding roofs, cut edge corrosion, gutters and flat roofs. If your site has more than one roof type, we can handle all of it.

Seal the roof in place with a durable coating system. No removal, no disposal, far less cost and disruption.

Seal the roof and turn it into an energy asset in one project. See the next section.
Over-cladding fits a new roof over the asbestos rather than treating it - usually more structural work, a higher risk of disturbing the fibres, and a shorter lifespan than encapsulation. Book a free roof survey and we'll tell you honestly which is right for your building.

SOLAR OVER ASBESTOS
Most contractors will tell you that you cannot put solar on an asbestos roof. ASL can. Using our own patent pending frame and bolt system, we fit a solar array over a safely sealed asbestos roof, so the same roof that was a liability starts cutting your energy bills.
Why ASL
Unlike many asbestos encapsulation contractors, ASL manufactures the systems we install. That means we have greater control over the products, the quality of the installation and the overall cost of your project.
Because there’s no third-party manufacturer or middleman adding another margin, we can offer a more cost-effective, streamlined solution from manufacture through to installation.
One company. One system. One accountable team.
Our in-house expertise means the system we manufacture is the system we install - giving you greater consistency, better control and a more competitive solution for your roof.
ASL has experience delivering roofing and asbestos encapsulation projects for major national operators, including Amazon, as well as large-scale retail and industrial environments.
Working in these high-demand environments means understanding that safety, compliance, quality and minimal disruption aren't optional - they're essential.
Our experienced teams are used to working around live operations, strict site requirements and demanding project schedules, delivering solutions that keep your building protected while helping your business keep moving.
If we can work around the demands of a national operator, we can work around yours.

How it works
We keep the process simple, transparent and managed from start to finish. Our team handles the detail, so you know exactly what to expect at every stage.
We visit your site to assess the condition of your roof, identify any areas requiring attention and understand your requirements.
You'll receive a clear proposal outlining the recommended works, costs and timescales, including any applicable tax relief opportunities that could help reduce the overall cost to your business.
Once you're happy to proceed, we'll arrange a pre-start meeting and agree the programme with you. Our experienced team then carries out the works using systems manufactured by ASL, with progress and quality checked throughout.
Once the work is complete, we'll provide your O&M documentation and project records, including your applicable guarantee and details of the system installed.
A roof needs looking after to perform at its best. We can provide a tailored maintenance schedule and ongoing inspection programme, with costs agreed as part of the project if required.
One team. One process. One point of contact.
From the initial survey through to installation and ongoing maintenance, ASL manages the entire process, giving you a straightforward route to a safer, longer-lasting roof.
