Clean and Protect Your Roof

Moss, algae and lichen cause mechanical and chemical damage to the factory protective coating on your roof. This means decay or erosion of the protective coating, possible rust, potentially expensive repair bills and an unmaintained, dirty appearance of your home.

Cleaning your roof with Bio-Shield® will kill and remove these destructive growths gently, without damaging the roof’s surface and provide extended protection from re-growths and at lower cost than other roof cleaning methods.

Over the past week the Association has been contacted by two of your customers who called to convey their gratitude and compliments on the high standard of workmanship and customer service provided to them. I would therefore like to congratulate your organisation, this has reflected well on not only your reputation but on that of the Association.
