The first stage to cleaning should therefore be to wet down the roof and scrape off any weed or moss growth which should be placed into designated asbestos waste bags.

I d imagine most people aren t too keen to scrub it with a wire brush for risk of particles getting inhaled and wouldn t a power washer be likely to damage the tiles. A north facing roof usually has little sunlight which enables moss to buildup on the roof.

It does take a bit of time for this process to work so you have to be patient. If the roof is pitched spray it with strong moss killer the moss killer should kill the roots which keep the moss attached to the roof. Removing asbestos from any part of your home is a very important step to limiting the possible exposure to this cancer causing agent. If the water will not reach the peak of the roof from the ground you can spray while standing on a ladder.

Certified companies can remove your asbestos roof tiles but if you choose to do it yourself take proper safety precautions. Liquid moss killers cover the roof more evenly than dry powders and they let you stay on the ground for the application. The roots and the moss shrivel up and wind rain and gravity wash the dead moss down into the gutter. Moss can grow quite quickly and it will grow in between roof tiles filling in the voids and lifting up roof tiles and slates.

This adds to the weight of the roof and in extreme cases can penetrate the asbestos cement severely weakening the already fragile surface.
