Leaky Roofs

In 2005 Malcolm began developing Renov-8 after discovering a new way of repairing roofs. Many roofs in this country, and of course throughout the world, suffer from porosity when they have aged. A seventy year old fibre-cement roof will have become porous, whether it is made of slate-like tiles or corrugated sheet. After testing the idea on a friend's roof, he used his expertise to develop Renov-8 and applied for a patent to cover its use in the marketplace.

A Cheap Solution

His friend was delighted because he had repaired his leaky roof for a fraction of the cost of a new one! The actual tiles were the last thing he suspected of causing damp in the plaster of the walls, which was falling off despite everything he had done to prevent it. If your roof tiles are damp on the inside it is likely that the rain is just coming straight through!


The photographs here show the results one and two months after treatment with Renov-8. The treatment was carried out in November so the drying out process was happening in the middle of winter. Despite this, the increasing appearance of dried salts proves that the moisture that previously was permeating the tiles is now being resisted.

Stonework Too

The process is also useful in treating old stone work where the stone has been attacked by acid rain and pollution. This can be seen on most lovely old buildings. So far the only solution is the very expensive replacement of the stone itself. Treatment with Renov-8 costs just a fraction of this, and can be done really quickly.

In its present stage of development the treatment is patented but not commercially available. Ifyou are interested in obtaining more details or a quotation please contact the Studio.
