Can you overclad an asbestos cement roof?

In many cases yes — overcladding encapsulates the existing sheets rather than disturbing them, which is often the lowest-risk and lowest-cost route. Where removal is the right answer we work with licensed removal contractors.

How long does an industrial overclad take?

A typical 2,000 square metre warehouse roof overclad runs in weeks rather than months, phased so the building stays in use throughout.

Will overcladding improve energy performance?

Yes. Adding an insulated skin typically transforms the U-value of an older single-skin or degraded built-up roof and reduces heat loss and condensation.

Roof Overcladding & Recladding

Overcladding installs a new insulated roof or wall skin over the existing one. It stops the leaks, upgrades the thermal performance and extends the life of the building without stripping the roof or emptying the unit.

For facilities managers and warehouse owners weighing up a leaking roof, a failing insulation value or a full strip-and-reclad against a lower-disruption overclad.

Overclad or strip and reclad?

An overclad is faster, cheaper and keeps the building watertight throughout because the original roof stays in place until the new one is over it. A strip-and-reclad is the answer where the existing sheets, purlins or fixings are beyond saving, or where asbestos has to come out.

Why owners choose overcladding

No decant, no stripped roof exposed to weather, far less waste to landfill, a measurable improvement in U-value and heating cost, and a roof with a fresh manufacturer-backed life expectancy.

How a UDM overclad runs

Survey and core sample, structural check on the existing frame, system selection and specification, access and edge protection plan, phased installation, then handover with warranties and an as-built record.
