Cold Weather and Cracks: Why Asbestos Cement Roofing Needs Attention Now
As temperatures drop and frost sets in, asbestos cement roofing becomes increasingly vulnerable to damage. For warehouses, factories, industrial units, and even older agricultural buildings, this seasonal change brings a higher risk of cracks, water ingress, and accidental disturbance of asbestos-containing materials (ACMs).
In this blog, we offer practical advice for building managers, facilities teams, and contractors working on commercial and industrial properties this autumn and winter. We’ll also explain why proactive action now can save you from unexpected disruption—and legal trouble—down the line.
Why Asbestos Cement Roofs Are at Risk in Cold Weather
Asbestos cement sheets—commonly used for roofing and cladding—were prized for being cheap and durable. But that was decades ago. With age and exposure to the elements, these sheets become brittle, and cold weather accelerates that deterioration.
Here's what can happen:
Cracks form due to thermal movement and frost
Sheet fixings loosen due to corrosion or repeated freeze-thaw cycles
Water seeps in, increasing the risk of internal damage and fibre release
Storm debris or maintenance traffic may cause breakages
A small crack now can easily become a major hazard by mid-winter.
Key Signs You Need an Inspection
If you're responsible for an older commercial roof, look out for:
Hairline cracks or flaking on the roof sheets
Signs of water ingress in the ceiling below
Debris or broken fixings on the floor or around downpipes
Moss or frost damage along roof joints
Any of these could point to asbestos roof panels deteriorating. If you're unsure, call a licensed asbestos contractor like Safe Asbestos Removal for an inspection.
Why You Shouldn’t Delay Action
Waiting until a leak appears or sheets collapse could:
Force a full roof closure during peak business periods
Result in emergency removal costs far higher than planned works
Risk an HSE investigation if staff or contractors are exposed
According to HSE statistics, commercial properties are among the most common sites for asbestos-related enforcement notices, particularly where maintenance has been neglected.
What You Can Do This Season
Here’s our step-by-step guide to keeping your asbestos cement roofing safe over the colder months:
Book a Visual Roof Inspection | Even if you’re not sure whether asbestos is present, our team can survey the roof and confirm material types. We'll document any defects and provide a practical, commercial-friendly report.
Schedule Repairs or Removal Outside Operating Hours | We offer weekend or overnight asbestos cement sheet removal for businesses that can’t afford downtime.
Plan for Winter Storms | Pre-emptively remove or encapsulate damaged panels before frost or wind cause further cracks. We can also install safe access systems for future maintenance.
Review Your Asbestos Management Plan | If your property is legally required to have one, now is a great time to update it. Make sure staff and contractors are informed of known ACMs.
When Removal is the Best Option
While some minor issues can be managed or encapsulated, you’ll likely need full asbestos roof sheet removal if:
The sheets are heavily cracked or damaged
There’s a plan to install solar panels or new insulation
Your insurer requires a safer modern roofing material
We offer:
Safe asbestos removal using licensed techniques
Full waste handling, disposal, and documentation
Replacement roofing solutions or referrals to trusted roofers.
