Why Clean Roofs Are Critical for Food Storage Facilities: A Guide to Commercial Exterior Cleaning

When it comes to food storage facilities, most people focus on the hygiene inside the building, sanitised surfaces, pest control, proper ventilation, etc. But there’s one crucial area that’s often overlooked… the roof.

Yes, that big thing over your head is more than just a lid for your building. If it’s covered in moss, algae, bird mess, or worse, it could be compromising the safety, cleanliness, and compliance of your entire operation. That’s where commercial exterior cleaning comes in.

Let’s break down why a clean, properly coated roof is non-negotiable in the food industry.

Moss, Algae & Mould: A Recipe for Contamination

Roofs on commercial buildings, especially large warehouses or food storage units, are exposed to the elements all year round. Rain, wind, birds, pollution, you name it. Over time, this creates the perfect breeding ground for moss, algae, and lichen. Not only are these unsightly, but they’re also surprisingly good at holding onto moisture, dirt, and bacteria.

And guess what loves bacteria? Pests.

If your roof becomes a rooftop buffet for birds or rodents, there’s a real risk of contamination, not just from droppings, but from decaying organic matter washing into gutters and potentially seeping into ventilation systems.

Suddenly, what seemed like a bit of harmless moss can land you on the wrong end of a food safety inspection.

The Role of Commercial Exterior Cleaning in Food Facility Safety

This is where commercial exterior cleaning becomes essential. It’s not just about aesthetics (though a sparkling clean roof does look far more professional). It’s a preventative measure, keeping biological growth at bay and helping you meet hygiene compliance regulations.

At The Roof Cleaning Experts, we carry out roof cleaning Essex wide and beyond, and we’ve seen it all. Warehouses with roofs so green they could’ve passed for meadows. Don’t be that warehouse.

Our cleaning process removes all organic matter, treating the roof with environmentally safe biocides to ensure nothing nasty grows back any time soon. We also offer roof coating services using ProPERLA, which adds a water-repellent barrier that keeps roofs drier, cleaner, and more resistant to microbial growth.

How Roof Coatings Help Prevent Contamination

Think of roof coatings as the final boss level of protection. A clean roof is great, but a clean and coated roof is the gold standard, especially for commercial food storage facilities.

Our ProPERLA coatings don’t just repel water – they’re breathable, self-cleaning, and highly durable. Once applied by our trained specialists, your roof will stay cleaner for longer, reduce energy costs (hello, thermal efficiency!), and most importantly, offer another layer of protection against biological nasties.

As one of the few ProPERLA Approved Platinum Applicators in the UK, you can trust us to get the job done to the highest possible standard. In fact, ProPERLA won’t even let us use their product unless we meet their strict quality checks, and we photograph and document every job to prove it.

Not All Roof Cleaners Are The Same!

Choosing the right roof cleaning company is essential. There’s a world of difference between someone with a pressure washer and a bucket of bleach and a team like ours.

All our staff are trained in:

  • First Aid
  • Manual Handling
  • IPAF & PASMA
  • Working at Heights
  • Ladder Safety
  • And more…


Plus, we’re fully insured and have over 1,000+ glowing reviews on TrustATrader; more than any competitor in our sector.
