Preparation

STEP 1: Fungicidal Wash

A treatment of Smartseal fungicidal wash is recommended to eliminate the underlying active infestation of moss & lichen spores. This will help prevent future re-growth and minimise further maintenance.

STEP 2: Roof Cleaning

The roof should be thoroughly cleaned by high pressure washing this will remove moss, algae, lichen, dirt and pollutants. Remember to take care during the roof cleaning process not to block existing gutters and downpipes.

STEP 3: Repairs

At this point it makes sense to repair any damaged areas on the roof. Defective mortar between crests, ridge and hip tiles can be hacked out and re-pointed using a fibre re-enforced polymer mortar. Also any loose ridges and crests can be re-bedded and damaged roof tiles replaced.
