Why should you clean your roof?

Removing organisms that stain your roof like algae, moss and lichen that can damage your roof surface.
Roof algae, lichen and moss can penetrate your roof and attack the timber framing causing rot.
In extreme cases your insurance company may cancel your insurance.
A dirty roof does not reflect sunlight in the way a clean roof does. Your dirty roof can cause your ceiling cavity or attic to get extremely hot in summer.
Cleaning your roof annually can prolong the life of the surface coating giving you a cost-saving alternative to re-roofing years sooner than needed.
Cleaning your roof reduces the risk of animal and insect invasion. Rotting wood attracts a variety of insects. They attack weak spots in your timber and make their home. Birds then eat the insects and soil your roof.
