Porous tiles absorb water, once wet they provide the ideal breeding ground for plants such as moss, lichen and once waterlogged become covered in algae.
In turn the flow rate of water from your roof can slow down, and your guttering systems and drainage can become blocked from the falling moss, not to mention the mess on paths and driveways.
In sub zero conditions the water inside your tiles, freezes and expands which leads to small cracks and eventually the tile may suffer from a structural failure, a full length crack or, start to crumble. This leads to water penetrating into your home. Damp homes encourage the growth of mould, which can be bad for your health.
Secondly we treat the tiles with an anti-fungal biocide to remove any biological contaminants, inhibiting the return of moss, lichen and algae.
Your roof renovation continues with the repair stage, where we remove all cracked, broken or unserviceable tiles and replace them with a new tile. In the case of a historic building or very old roof with Kent peg tiles, will will source and use serviceable reclaimed tiles that are individually checked, inspected and cleaned prior to replacement.
