Full roof restoration comprises the following important stages:
Stage 1. Cleaning
its important before painting any surface, especialy roofs, that the surface is cleaned properly, otherwise the most expensive paint will not stick to it for too long.
We use a very high pressure cleaning unit to clean years of hard dirt buildup, moss and lichen from your roof. We pay special attention to areas where tiles are overlaped, the gap on these areas are almost imposible to reach and clean manualy. Of couse the roof has to be water tight before cleaning so the water doesn't get in to roof cavity.
*we will clean any residual mess as always.
The pressure of the cleaner unit is adjustible and we will gently and with low pressure, clean any mess we may create from walls, windows, fascias, gutters and foot paths.
Stage 2. Preperation for painting Replace any broken faulty tiles, ridge capping and badly rusted valley iron. Repair / replace or treat minor rust of flashing.
Repair / replace or treat minor rust of flashing, replace any badly rusted roof sheet, treat minor rust and rescrew loose sheets (if metal roof).
Rebed / rebedding:
- Lift and leave aside ridge capping, valley and gable tiles.
- Remove the existing old crumbling mortar / cement.
- With a blower unit remove all small leftover particals and dust.
- Lay new foundation (mortar) and reset back all ridge capping and tiles.
Repoint / Repointing: a compound (*ridgebond or flexipoint) is applied by trowel over the bedding to a thickness of 3mm and applied to all ridge capping, valleys and gables tiles. This provides a neat, waterproof finish.
*Ridgebond is a fine sand based sticky compound. It's waterproof, durable and protects the bedding to last longer. It will not go hard and brittle like mortar alone, so it won't crack or fall with roof movement. It expands and contacts like rubber, comes in already made up buckets of 10 litres and in a range of colors to match most tiles, in particular terracotta tiles.
Stage 3. Painting:
We use a powerful spray unit to paint the roof. Our roof paint is very thick, almost like yoghurt, and provides a durable, long lasting finish.
We firstly apply a coat of sealer / undercoat which makes the paint stick to the tile surface. Next we apply 2 two top coats in the chosen colour. To avoid mess and over spray, some areas will be brush painted such as skylight flashings and fluepipes on top of brick chimneys. We protect and cover areas that are not supposed to be painted such as skylight domes.
We use the highest quality roof paint, it's UV resistance means minimal colour fading. It is flexible, waterproof and resists harsh weather conditions. It is also safe for collection of drinking water and it lasts, performs and looks as good as a new roof.
Terracotta roof tiles should never be painted. but we do glaze them (optional) with 2 straight coats of semi or full gloss terracotta glaze.
Metal roofs, if the surface is in good condition we will use 2 straight coats of metal roof paint/sealer. If the roof surface is too old and too poor or needs many repairs prior to painting, we may need to apply one coat of sealer / under coat.
Cleaning and preparation is the same as above.
