Question 1

How often should I have my roof cleaned?

Accepted Answer

Most roofs benefit from cleaning every **2 to 5 years**, depending on factors like shade, nearby trees, and local weather conditions. Roofs prone to moss or algae growth may need more frequent attention.

Question 2

Will moss and algae grow back?

Accepted Answer

Some regrowth is possible, but applying a biocide treatment after cleaning can significantly reduce it, often for **12 to 24 months.** Regular maintenance also helps keep growth under control.

Question 3

How long does roof cleaning take?

Accepted Answer

Most standard roof cleaning jobs take 1 to 2 days, depending on the size of the roof and the level of moss or algae present. Larger or multi-storey properties may take longer.

Question 4

Do roof cleaning professionals need qualifications?

Accepted Answer

No formal qualifications are required, but it’s a good idea to check if roof cleaners have experience, training in working at height, and insurance to ensure safe, effective work. Plus, all tradespeople on MyBuilder undergo checks at registration, such as ID documents, company details and skill assessments, allowing you to hire with confidence.
