Apart from the obvious aesthetic benefits to a clean roof, there are many more serious reasons why you should remove build up from your roof:-
- Moss, algae and lichens on your roof absorb and retain water.
- Weight on the roof is increased as water weighs 1 tonne per metre cube (m3). This stresses the roof and supporting structure.
- Damp battens and roof structures under increased load will eventually buckle and warp. This can be clearly seen on some buildings.
- Roof tiles constantly wet eventually become porous
- Wet tiles splinter and break when subjected to frost
- Wet sand and cement mortar will splinter and break
- Roof tiles, ridge, hip and bonnet tiles can become dislodged.
- Damp battens and roof structures start to deteriorate through damp rot, dry rot etc.
This all means water penetrates the roof space and causes damage!
As Part of our service, we not only clean your roof but undertake appropriate repairs to ensure it is watertight and weatherproof.
