When the need for cleaning a glass roof arises, there is a sequence of steps to serve as a guideline and this varies on the type of glass roof; either conventional glass roofs, double-glazed windows, or conservatory roofs.
The first step is taking inventory of your cleaning appliances and safety gear. The instruments used in cleaning glassware like glass roofs differs from normal household cleaning appliances, this is because of the fragile nature of the glass. The safety gear and appliances should include gloves, safety boots, a ladder, a bucket, a little bucket, and a squeegee if available. There are cases where the position of the glass fitting has some edged designs that aren't easy to access, so you should try to add a telescopic brush to your inventory.
