Preparing Your Commercial Property Roof for Winter: Essential Maintenance Tips

As the days grow shorter and temperatures begin to drop, it’s the perfect time for facilities managers to turn their attention to the condition of their roofs. Winter weather in the UK can be unpredictable—heavy rain, strong winds and occasional snow all place extra strain on roofing systems. A little preparation now can help prevent costly leaks, emergency call-outs and disruption to your operations when the bad weather sets in.

At this time of year, the majority of our emergency call-outs are to roofs that already had hidden weaknesses—loose slates or tiles, blocked gutters, or flat roofs with standing water. A proactive approach is far more cost-effective than waiting for the next downpour to reveal a problem.

With winter on the horizon, now is the perfect time to ensure your commercial property is ready for whatever the UK weather has in store.

Here are our top recommendations:

1. Schedule a Professional Roof Inspection

An annual inspection—ideally in spring or early autumn—is the single most effective way to maintain the integrity of your roof. A professional survey highlights any damage caused by the previous winter and gives you time to carry out repairs during drier months, reducing the risk of leaks when temperatures drop.

2. Keep Gutters and Downpipes Clear

Leaves, moss, and debris can quickly build up in gutters, causing blockages and overflow that leads to water damage. We recommend cleaning and checking gutters and downpipes at least twice a year: once in late autumn to prepare for heavy rain, and again in spring as part of your annual maintenance programme.

3. Act Quickly on Minor Repairs

Don’t underestimate the impact of a single loose slate or cracked tile. Even small gaps allow water ingress, creating moisture that leads to mould, timber decay, and costly internal damage. Prompt repairs save time and money by preventing minor issues from becoming major structural problems.

4. Inspect Chimneys and Flashings

It’s not just the main roof covering that needs attention. Chimneys, flashings, and roof penetrations are common entry points for water. During your annual inspection, ensure all flashing is secure, mortar is sound, and chimney pots or flue covers are intact.

5. Check Inside for Early Warning Signs

Lofts, attics, and ceiling voids should be checked for damp patches, staining, or mould. Identifying a leak from the inside often reveals problems before they are visible externally.

6. Prepare for Severe Weather Events

Commercial roofs in the UK must withstand heavy rain, high winds, and occasional snow or ice. Make sure drainage outlets are clear, roof membranes are intact, and any rooftop equipment (HVAC units, vents, solar panels) is properly secured.

7. Plan for Access and Safety

If your property requires high-level maintenance, safe access is critical. Specialist equipment such as MEWPs (mobile elevating work platforms) or rope access may be needed. Partnering with a professional roofing company ensures compliance with health and safety regulations and protects your team from unnecessary risk.
