Can it be effective for red & black algae on cream-rendered exterior walls, without damaging the render finish?

Green Clear PRO can be used to kill and remove red and black algae on cream coloured render. A soft brush can be used to remove organic growth on badly contaminated areas.

How would your product be applied to a house roof?

Green Clear PRO is usually applied by a sprayer. In the case of house roofs, depending on access, it can be sprayed from a ladder or scaffolding. If the roof is not that high, then it can be applied using a sprayer and an extendable lance.

Does it also clear weeds, please?

Green Clear may kill some types of weeds, but is not regarded as a weed killer. It would be best to purchase a specific weed killer for that purpose.

Is this product animal/bird friendly?

We would not classify the Green Clear Pro as animal or bird-friendly immediately after application. Once dry, it is totally safe for birds and other animals to walk on.
