Would you know if the treatment being sprayed over your roof was actually legal to use?
Most people wouldn't.
And why would you?
You're paying somebody to clean your roof. You shouldn't need to spend your evening researching chemical regulations beforehand.
But biocides are regulated, and where approval is required, the product needs that approval before it can legally be supplied and used.
That's one reason we're particular about what we use.
Our treatment is BacClear Pro BAC50 from PureSeal Services.
It's a licensed professional surface biocide, registered on the HSE's COPR database under No. 10878, with specific guidance for professional roof use.
So there's no mystery around what's being put on your property.
It has a name.
A manufacturer.
Proper product information.
And a registration that can actually be checked.
BacClear Pro is also bleach-free, acid-free and non-caustic.
Its active ingredient is BAC â benzalkonium chloride.
If you've never heard of it before, you're probably not alone.
BAC chemistry is also widely used in disinfectant products, including a range healthcare products too.
That doesn't make our roof treatment exactly the same as hospital disinfectant, and that doesn't mean we're going to be scrubbing your roof with disinfectant wipesđ
It simply gives a bit of perspective to a name that sounds far more intimidating when you've no idea what it actually is.
We don't expect customers to know the chemistry.
We don't expect you to understand HSE regulations either.
But we think the company putting something over one of the most important parts of your home should.
And we think you should always be able to ask what they're using and get a straight answer.
