Moss and Mould Treatment

For a Decramastic roof we use a fast-acting Moss and Mould Treatment that is sprayed on to the roof to kill any and all moss, mildew and lichen growth on the roof.

With our fast-acting Moss and Mould treatment that we apply, the roof only needs a rinse to remove all the dead moss, mildew and lichen.

Roof Repairs


Ridge-Cap Replacement

The ridge cap of a decramastic roof serves a great purpose as it seals and joins the two sides of the roof. If it has deteriorated or is loose it could leave the roof exposed and cause a leak. it is best to get repaired or replaced as soon as possible.


Tile Replacement

Once a decramastic tile has been to badly dented it creates a tear water can penetrate. If not replaced or repaired the leak can cause further damage to the structure or inside of your house.


Batten Replacement

A batten is an essential to support the tiles and if one is broken or soft, the tiles dip and creates a possible leak. The batten needs to be replaced with new timber and then properly nail down the tiles.
