The Marshall Air Roof Scraping System: Honest Review

A Game Changer for the Roof Cleaning Industry?

Disclaimer: I am not affiliated with Marshall Air and have not been paid to write this post.

To Be Clear: I won the Marshall Air Kit in a raffle. When I reached out to the owner to ask if I could return the favour in any way, his only request was for me to be honest when talking about the equipment.

This review is based on approximatley 16 hours of use, so my experience is limited, but I wanted to share my early impressions for customers and professionals alike.

First Impressions

As a UK-based exterior cleaning company, we’re always on the lookout for new tools that can improve our efficiency and results. We had seen speak of this new equipment entering the market over the last 12 months and became really lucky when we won this at a suppliers Christmas Raffle.

Roof scraping is a regular part of our workflow, and while manual methods get the job done, they’re often labour-intensive and time-consuming. Enter the Marshall Air – an air-assisted scraping system that aims to streamline the process and deliver more consistent results.

After a short initial use on a job with heavy, dry moss buildup, here’s what I found.

Positives

✅ Professional Finish, Better Results

From the moment you unpack it, the kit looks professional – and more importantly, it delivers. Compared to traditional scraping, the Marshall Air system removes moss faster and more thoroughly, particulalry on the edge of profiled tiles.

✅ Reaches Where Manual Scrapers Can’t

Thanks to the air-assisted design, the system blows air between roof tiles to dislodge moss from areas that would be near-impossible to reach manually. This saves time and ensures a more complete clean.

✅ Efficiency Boost

No need to go over an area multiple times with different scraper attachments. The air movement helps loosen and push moss down in one pass, reducing repeat work.

✅ Quick and Easy Setup

Setup is straightforward – within 5 to 10 minutes of arriving (depending on roof access), you can be ready to go. This is a huge bonus when working to tight schedules.

✅ Lightweight and User-Friendly

The scraping head and brush are surprisingly lightweight, which reduces fatigue and makes handling the pole more manageable over longer periods.

✅ Client Appeal

Some homeowners prefer scraping or soft-washing methods over pressure washing, believing they’re gentler on roof tiles. Offering this as a service may attract a broader customer base.

✅ Double Up for Efficiency

With the option to run two poles and hoses from a single machine, you can have two operatives scraping at once – a real bonus for large properties or tight deadlines.

✅ Adaptable to Different Roof Profiles

The Marshall Air head supports different profile blades, meaning it can be tailored to suit various roof tile shapes – a flexible solution for varied property types.

Negatives

⚠️ No Instant Transformation

Like manual scraping, the Marshall Air doesn’t give the instant visual transformation you get with low-pressure deep cleaning. It relies on post-clean biocide treatment for full effect so expectations need to be managed with clients.

⚠️ Still Physical Work

Let’s be clear: this isn’t a magic wand. You’ll still get a good workout on the pole, especially on larger roofs. It is easier and faster than manual scraping – just not effortless.

⚠️ Refuelling Required

The machine's fuel tank lasts around 2 hours, so depending on the size of the roof, you may need to top up a couple of times a day. Not a dealbreaker, especially considering the quality of the scraping. 

⚠️ Higher Initial Cost

For those starting out in roof cleaning or running a smaller outfit, the price may be a hurdle. But for businesses doing regular scraping work, it’s an investment that could pay off quickly.

Test VS Manual Scraper

The image below shows what was achieved with a manual scraper vs the air marhsall pro. The manual scraper result is on the left and the air marhsall on the right. 

As you can see we have covered roughly the same area in 3 minutes. 

However, the amount of moss which has been removed by manual scraping is significanlty less. This would need to be repeated again with another blade to achieve any significant results. 

Whereas the Air Marshall has removed alot more moss and needs less time to get a better result. 

Future Considerations

🧪 Yet to Try on Wet Moss

My use was on a roof with heavy, dry moss. It’ll be interesting to see how the system handles damp, slimy moss – something I’ll hopefully be testing soon.

 🌬 Moss Particles & Wind

The system blows lots of moss fragments off the roof. On windy days, this could be harder to control, possibly affecting neighbouring properties. It might also be worth wearing a mask while using it, especially when working upwind.

💧 Biocide Sprayer Option (Pressure Pot)

Marshall Air also offers a pressure pot attachment for applying biocide post-clean. I haven’t tested this yet, so can’t speak to its effectiveness – but it’s a promising add-on worth exploring.

Final Thoughts

If roof scraping is a big part of your workflow, the Marshall Air Kit could be a serious upgrade to your toolkit. It’s quick to set up, efficient and delivers professional results. While it doesn’t eliminate the need for elbow grease, it significantly reduces the time and effort compared to traditional methods.

I’ll share another update after I’ve spent more time with the machine and tested it in different conditions – but so far, this feels like a big step forward for the roof cleaning industry.

I do believe this could be a game changer for Roof Scraping Services.
