AC roofs · Cladding · Portal-frame · Plant rooms
Industrial and warehouse asbestos — it's mostly on the roof.
Portal-frame industrial units built between 1950 and 1999 almost universally have asbestos-cement roofs and often cement or cladding-panel side walls. The material is safe in situ, but every re-roof, gutter clean, PV installation, insurance survey and demolition triggers a duty to manage.
Overview
What actually matters in industrial & warehouse.
Cement asbestos was the dominant roofing material for UK industrial and warehouse buildings for nearly 50 years. In our data, more than 85% of portal-frame units built before 1999 still have cement roofs — often now weathered, cracked and shedding fibres into gutters.
Gutter linings, downpipes, bitumen felting, ridge caps and rooflights all commonly contain asbestos. Where the roof has been over-clad, the original AC sheet is very often still in place beneath the new profile.
For owner-occupiers, landlords and tenants alike, an R&D-grade roof and cladding survey is the correct baseline before any roof access, PV installation, re-cladding or demolition. Where the building is operational, a Management Survey covers the standing-day duty.
Era-by-era context
What was original, and what got added later.
1950s–70s portal-frame units
Steel or concrete portal frames with cement AC roofs, cement cladding, cement gutters and cement flues.
1980s–90s distribution sheds
Continued use of cement roofs and cladding right up to the 1999 ban. Later over-cladding often left original AC sheet in place.
Plant rooms and boiler houses
Pipe lagging, boiler insulation, calorifier jackets — legacy findings in every era.
Typical asbestos locations
Where we find it most in industrial & warehouse.
Cement roof sheeting
The default risk. Safe if unbroken and not walked on; degrades with weathering.
Gutter linings and downpipes
AC gutters and downpipes — often filled with weathered fibre debris.
Cement cladding panels
Side and gable elevations, often behind later over-cladding.
Rooflight fixings and mastics
Bitumen mastics and gaskets around GRP rooflights.
Plant-room lagging
Pipe lagging, boiler insulation and calorifier jackets.
Textured coatings and Artex to office areas
In the offices-and-amenities blocks attached to warehouses.
Common scenarios
The situations clients come to us with.
Pre-purchase or pre-lease survey
R&D-grade roof and cladding inspection with photographic condition report, informing the cost model.
Re-roof, over-clad or PV installation
Full R&D survey with cement roof management plan and, where required, licensed removal specification.
Insurance-driven inspection
Following a fire, storm or roof failure, insurers routinely require an asbestos report before reinstatement.
Demolition
R&D survey of the entire structure, with removal specification and disposal audit trail.
Recommended surveys and services
The right survey for the job — no upselling.
We are consultancy-only. Every recommendation is scored on risk, not scope of work.
Refurbishment & Demolition Survey
The right survey before any roof access, over-cladding, PV installation, re-roof or demolition.

Book lab analysisFrequently asked
Industrial & Warehouse — the questions clients ask us first.
Do I need to remove a cement asbestos roof?
No — cement sheeting is safe in situ if unbroken and not walked on. Remove only when the roof is beyond service life, being over-clad, or being demolished.
Can we install solar PV over an asbestos roof?
Only with a full R&D survey, a written cement-roof management plan, and — usually — either roof replacement or a ballasted PV system designed to avoid penetrations.
