The problem

An ageing asbestos roof does not get cheaper by waiting

You already know the roof needs dealing with. The worry is what it costs and what it does to your operation. Most owners assume the only option is a full strip and replace: licensed removal, disposal, downtime, and a bill that runs into serious money.

So it gets put off, and meanwhile the leaks, the maintenance calls and the duty to manage that asbestos safely do not go away. There is a better route, and most contractors will not tell you about it.

The solution

EncapsulationSeal it in place, at a fraction of the cost

Encapsulation seals your asbestos roof where it is, with a coating system that locks it in and stops the leaks, with no tear off and no costly disposal. Your building keeps running while we work.

Here is what makes ASL different on price: we manufacture and install our own systems, so you are not paying a contractor's margin on top of a supplier's margin. You save twice on the same job.

Asbestos work can also qualify for Land Remediation Relief, up to a 150 percent corporation tax deduction, so speak to us about that too.

What we do

Two ways to deal with an indasbestos roof

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.

Asbestos Encapsulation

Asbestos Encapsulation

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

Asbestos Encapsulation with Solar

Asbestos Encapsulation with Solar

Seal the roof and turn it into an energy asset in one project. See the next section.

SOLAR OVER ASBESTOS

Turn a Problem Roof Into One That Pays You Back

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

Why commercial property owners choose ASL

We make and fit our own systems

Most asbestos encapsulation companies buy in their materials and add a margin. ASL manufactures and installs its own, so you save twice on the same job.
