Roof Cleaning

What Does Roof Cleaning Involve?

Although it differs from job to job, broadly speaking, commercial roof cleaning is the process of removing algae, moss, trash and debris from the surface of your rooftop. The goal is leaving your roof looking as good-as-new.

You might be tempted to clean your roof yourself, most retail products simply aren’t effective enough at removing tougher particles from the surface and their effectiveness will vary depending on the roof type. Common methods used to wash roofs include soft washing, biocide treatments and pressure washer cleaning.

At APT-ICC, we pride ourselves on achieving long-lasting results that leave your roof looking – and performing – at its best for years to come.

Why is Roof Cleaning Important?

Roof cleaning is particularly important when the weather turns colder.  If moss freezes during the winter months, it can cause frost heave and ice dams. Both of which cause considerable damage to your underlying roof tiles. These frost and ice dams can cause structural problems too, due to the extra weight bearing down on your roof.

If that wasn’t enough, algae, mould and moss are all living organisms. So, the longer you leave them, the more they multiply. All while physically eating away at your roof. The mere presence of algae, mould and moss also attracts bugs that thrive in those conditions.

As well as looking unsightly, should mould and algae get into your heating and cooling system, you could be putting your employees and clients at risk of some unpleasant side effects.

Our specialist commercial roof cleaning services prevent damage to your building and the people within it by removing all traces of moss and algae.

Working around your business 24/7, it’s no wonder we’re one of the UK’s top roof cleaning companies. Here’s what our clients have to say about us:

“As Director of Estates on a very busy military airfield (RAF Odiham, home of the UK Chinook Force), I employed the services of APT-ICC Ltd to clear guttering and clean facades of buildings that had fallen outside routine maintenance for several years. The results were dramatic; not only did the buildings look superb, but the inherent problem of grey water causing damage to structures was also reduced.

I must commend the on-site delivery team for their professionalism and flexibility. They were very sensitive to the operational needs of the RAF and understood SAFEGUARDING principles when working at height and ‘air-side’ near manoeuvring aircraft.”J Edwards – RAF Squadron Leader – Ministry of Defence – RAF Oldham

What Are the Benefits of Bringing in Professional Roof Cleaners?

Cleaning away the grime and dirt from your roof not only looks good but has other benefits too. These include:

Save money on repairs
Moss, algae and other particles eat away at the roofing beneath them. By getting your roof regularly cleaned, you’ll keep your roof tiles looking and performing their best for years to come.

Offering – quite literally – a clean slate, you can rest easy knowing your roof is in tip-top shape.

It’s better for your health

Did you know that a mouldy rooftop might be violating local health regulations?

If mould, algae and moss make their way into your heating or air conditioning systems, you could be putting your business in jeopardy – no matter the industry.

And even if it (thankfully!) doesn’t make its way inside, you could be putting off potential clients and customers by having a scruffy roof.

By washing away murky grime from your roof tiles with a reputable commercial roof cleaning service like ours, you’ll keep your workforce protected.

You can see the condition of your roof

Dirt, debris and algae can obscure the condition of your roof. By covering imperfections, you could easily miss signs of degradation.

By cleaning your roof regularly, you’ll be able to spot these problems early on. For example, finding a weakened seam could save you thousands of pounds by allowing you to intervene early.

It saves you from working at a height

If nothing else, roof cleaning and moss removal is always best left to commercial roof cleaning companies due to the danger of working at height.

Roof Cleaning FAQs

At APT-ICC, we use many specialist techniques to guarantee the results you’re looking for. These include:

  • Hand scraping: This removes the dirt, algae and moss by manually scraping tiles clean.
  • Chemical cleaning: Chemicals offer a safe way for you to remove unwanted deposits from roof tiles. Softwashing your roof with specialist chemicals will give your roof a uniform clean. This is visible from the outset.
  • Steam cleaning: Safe on most roof tiles, low-pressure steam cleaning works to remove any unsightly deposits on your roof whilst also being eco-friendly and kind to surrounding areas.
  • Biocidal washes: One of the most popular methods of roof cleaning, moss is removed manually before a chemical solution is applied. This kills any stubborn organisms still residing on your roof, keeping them at bay for years to come.

Yes, it is! As well as looking unsightly, moss retains water like a sponge. When this water freezes, it causes your roof tiles to crack.

And worse still, if you have an abundance of moss on your roof, this heavy soilage forms a blanket over your roof tiles. Over time, this leads to rotting, bacteria and mould growth – all of which will significantly shorten your roof’s lifespan.

How much our commercial roof cleaning services costs depends on the type of building, the extent of moss, algae and debris and the cleaning method required.

Before every project, we’ll carry out a no-obligation site survey. During this, we’ll assess your building and discuss your particular needs. Then, our experts will recommend the best approach to guarantee superior results – and let you know how much it’s likely to cost.

Generally speaking, it’s a good idea to draft in commercial roof cleaners once per year. By doing this, not only will you keep your building looking pristine, but you’ll be able to catch any problems before they worsen.

If you’ve recently had a brand-new roof installed, you may only need a thorough roof clean every one or two years.

By investing in regular, professional roof cleaning services, you’ll restore the appearance of your roof and remove any unwanted grime, moss and algae.

As well as reducing discolouration, by investing in commercial roof cleaning, you’ll be able to accurately assess the condition of your roof, helping to improve its overall lifespan.

No, you shouldn’t. Although pressure washing is one of the cheapest ways to clean a roof, it’s also a technique that’s likely to cause damage.

This leads to a false economy as although the cleaning itself will be cheap, the cost of repairing broken tiles isn’t!

We’ll never use pressure washing at APT – only industry-leading, safe techniques.
